Spring is warm and flowers are blooming, all things are recovering, and at this time, it is time for animals to breed again. In the animal husbandry industry, preparations for animal reproduction have begun. Among them, "semen" is inseparable, which requires not only quality assurance, but also quantity. Under such demanding conditions, the preservation of semen becomes the focus. As we all know, semen preservation is to store it in an ultra-low temperature environment after special treatment to achieve long-term preservation. Usually stored in liquid nitrogen at -196�°C. The advantage is that it can be stored for a long time and its use is not limited by time, region and animal life span. At the same time, as a container that accompanies the demand for liquid nitrogen storage, the livestock liquid nitrogen tank can provide a vacuum insulated environment for the liquid nitrogen medium, extend its use time, and thereby preserve frozen semen. It has gained countless popularity because of its small size and light weight. User approval. However, for the safety of frozen semen, you should pay attention to the following points when using livestock liquid nitrogen tanks: 1. When storing and withdrawing frozen semen, the lifting tube is only allowed to be lifted below the mouth of the tank, and the time out of liquid nitrogen shall not exceed 10 seconds. If necessary, it must be immersed again before extraction; 2. When transferring frozen semen, the lifting tube should not be separated from the liquid nitrogen for more than 5 seconds; 3. After storing frozen semen, the tank plug should be capped in time to reduce the number and time of opening the cap plug to reduce liquid nitrogen consumption and prevent foreign matter from falling into the tank; 4. Frozen semen of different varieties should be numbered clearly to avoid confusion. 5. Liquid nitrogen tanks used for long-term storage of frozen semen should be cleaned and scrubbed regularly to avoid collisions. If the liquid nitrogen consumption in the tank increases significantly, or if there is frost on the outside of the tank, it should be replaced in time and repaired and replaced.
The use of liquid nitrogen has become increasingly common in scientific experiments and medical fields. As an ultra-low temperature liquid, it requires special containers, namely liquid nitrogen tanks, for storage and transportation. Liquid nitrogen tanks are a series of low-temperature containers that are made of aviation aluminum and have double-vacuum structures. They can only be used for liquid nitrogen storage or transportation. The advantage is that they are well insulated and can store liquid nitrogen for a long time, so that liquid nitrogen can be used to freeze biological samples. The disadvantage of using it is that it is difficult to move after loading liquid nitrogen and samples, and it is afraid of bumps. The connection between the neck tube and the inner tank cannot withstand shaking. However, in the storage of experimental samples, it is difficult not to involve the issue of indoor transportation. After all, it must serve the experimental subject. then what should we do? Under this demand, the liquid nitrogen tank trolley came into being! It is a tool specially designed for transporting liquid nitrogen containers. It has become an indispensable helper in the laboratory with its advantages of durability, wear resistance, collision resistance and ease of movement. The liquid nitrogen tank trolley is made of 304 stainless steel. The mechanical properties of the steel enable the trolley to maintain core stability when transporting liquid nitrogen containers and not deform due to constant pressure. For some emergencies, such as collision and friction, the wear resistance and collision resistance of stainless steel can effectively reduce the impact on the container and ensure safe transportation. In addition, the trolley is equipped with universal wheels. This user-friendly design makes movement more convenient and allows users to easily transport liquid nitrogen containers from one place to another. This is undoubtedly a great boon for laboratories and medical institutions that need to frequently move liquid nitrogen containers. The emergence of liquid nitrogen tank trolleys has effectively improved transportation efficiency and reduced labor costs. In short, liquid nitrogen tank trolleys have become an essential tool for transporting liquid nitrogen containers due to their durability, wear resistance, collision resistance, and convenience and ease of movement.

Quality without compromise, always get the exact rug you see on our website. We are the market leaders in Cowhide products. An obsession with quality has been the hallmark since our family business. Our hides have adorned homes and businesses. Do this to care for your cowhide rugs Shake out leather & cowhide rug instead of vacuuming them to remove loose dirt & dust. (Never use a beater bar on them! Shaking out rugs gives them a chance to â??breatheâ?? some fresh. Gently brush animal skin rug in the direction of the grain (or the hair growth if itâ??s a fur rug). Leather rug with hair, use lightly brush the leather with a wire rug brush designed for brushing for (like a wire bet brush).try to remove as much dust, dirt, and grime as you can with the brush. Give your cowhide rug plenty of time to air dry by draping it (evenly) over a banister or railing, make sure your rug have dried completely before placing them on your floor, furniture or walls never use heatâ??like the sun or a hair dryerâ??to dry cowhide rugs. Air your cowhide rugs out every few months by hanging them fur-side down over a banister railing outside in the sun.do this for no more them 1-2 hours at a time though; the idea is to give your rugs a healthy dose of fresh air after being cooped up inside gathering dust and dirt, a little bit of sunlight is good for rugs.
A pneumatic piston pump, also known as an air-operated diaphragm pump, is a type of positive displacement pump that utilizes compressed air or gas to transfer fluids. It is widely used in various industries for pumping liquids with varying viscosities, including chemicals, paints, adhesives, sludges, and more. The pump operates based on the reciprocating action of a piston driven by pneumatic pressure, allowing for efficient and reliable fluid transfer. The working principle of a pneumatic piston pump can be broken down into several key steps: Pneumatic pressure supply: The pump is connected to a source of compressed air or gas, typically at a regulated pressure. This air supply acts as the driving force for the pump's operation. Air distribution system: The pump is equipped with an air distribution system, consisting of control valves, air chambers, and diaphragms. These components regulate the flow of compressed air into specific areas of the pump to initiate and control the reciprocating motion of the piston. Intake stroke: When the compressed air is directed to the appropriate chamber, it pushes against the diaphragm connected to the piston. This creates a partial vacuum in the pump's inlet chamber, causing the fluid to be drawn into the pump through an inlet valve. The fluid flows into the pump's chamber as the piston moves away from the inlet, enlarging the space within the chamber. Compression stroke: As the piston reaches the end of its intake stroke, the air distribution system redirects the compressed air to the opposite side of the pump. This pushes against the diaphragm connected to the piston, causing the piston to move in the opposite direction. This motion reduces the volume of the pump's chamber, compressing the fluid inside.

Frozen embryos are one of the prerequisites for implementation, the other is the cultivation of embryos. After the eggs and sperm are completely extracted, in order to ensure the viability of the eggs and sperm, they will immediately enter the cryopreservation stage, suspend their life activities, and then complete insemination in an external culture system to complete the embryo development. After the embryo is transplanted into the uterus, it still needs to be stored at low temperature. The method of preservation is to put it into a low-temperature medium - liquid nitrogen. Since the temperature of liquid nitrogen is much lower than normal temperature, organisms in direct contact will be frozen. Otherwise, the plastic will be frozen brittle. In order to ensure the vitality of the sperm and egg "combination" embryo, a special liquid nitrogen container is needed to store it. We can also call it an embryo storage tank, because it is used for embryo storage at this time. The embryo storage tank is composed of two layers: an inner and outer bladder. The inner and outer layers are insulated by a vacuum. It has good thermal insulation and can reduce liquid nitrogen consumption. Even so, the liquid nitrogen balance and temperature in the tank need to be tested every day to ensure that the ambient temperature of the cryopreserved embryos is normal and stable. In order to ensure the safety of the embryos and improve work efficiency, we can install a liquid level alarm, which can detect the liquid level in the tank. When the ambient temperature reaches the upper and lower limits, an alarm will sound to remind the staff to replenish liquid nitrogen in time. It also supports text messages. , telephone, and email alarm functions. The addition of a liquid level alarm can avoid embryo loss caused by insufficient liquid nitrogen. This safety measure ensures the safety of the embryonic baby to a certain extent, preventing the embryonic baby from being harmed by the external environment and receiving the same careful care as in the mother's body. It not only improves the success rate of IVF, but also improves the efficiency of laboratory work management. Moreover, using embryo storage tanks to freeze embryos ensures their vitality during the period between the completion of cultivation and delivery to the mother, reducing damage to the embryos due to temperature changes, etc., and ensuring the success rate of IVF.
When there are a large number of stem cell samples that need to be preserved, whether it is the founder of the cell bank, the manager of the hospital blood bank, or the personnel of the preservation center, they all choose a specialized cell storage tank - a gas-phase liquid nitrogen freezer. This liquid nitrogen container Can popular branch! Because it has the advantages of large capacity, small daily evaporation loss of liquid nitrogen, safe and reliable use, and easy operation. In addition to stem cells, it is also suitable for the long-term static storage of various tissues and organs such as plasma, semen, and embryos. Originally made for the storage of plasma and stem cells, it has been widely recognized and favored by blood stations, cord blood banks, sperm banks and other institutions since its launch. What are the advantages of using a gas-phase liquid nitrogen freezer to preserve stem cells? 1. The tank body is made of high-quality stainless steel, with polished surface, good load-bearing, low temperature resistance and corrosion resistance; 2. The tank mouth is designed with an offset structure, large capacity, high vacuum, and low liquid nitrogen loss; 3. Two storage methods, gas phase and liquid phase, can maintain a low temperature environment of -190�° on the top of the jar; 4. Rotating trays are used internally for partitioned storage, making it easier to take out cells; 5. It has an intelligent monitoring system and can modify parameters in the settings according to needs; 6. The system can display high and low liquid levels in real time. Ultra-high and ultra-low will provide liquid level alarms, over-temperature alarms, and automatic control of fluid replenishment; 7. It has a hot gas bypass leakage function in the pipeline. The hot gas in the pipeline will not enter the tank during liquid replenishment, ensuring a low-temperature storage environment to the greatest extent; 8. It has a cover-opening and defogging function, which makes it easy to see the stored items and make them easy to extract;
The stainless steel liquid nitrogen tank is also a self-pressurizing liquid nitrogen tank. The tank itself has a pressurizing system and is adjusted through a pressurizing valve. When the booster valve opens, the pressure increases, and when it closes, the pressure decreases. During use, what is the reason why the booster valve is opened but unable to boost pressure? The reasons why the pressure does not rise after the booster valve of the self-pressurized liquid nitrogen tank is opened are as follows: 1. The booster valve is damaged When the vent valve and the inlet and outlet valve are closed, and the pipeline is unobstructed but does not pressurize, it means that there is a problem with the booster valve itself and the booster valve needs to be replaced. You can contact the manufacturer for replacement. 2. Pipe blockage The main reason for pipeline blockage is that external air and moisture enter and are not discharged in time. Under the influence of low temperature in the tank, they condense into ice and block the pipeline. The correct way to clear the pipe is to use hot nitrogen or hot air to blow away the ice and clear the pipe. After unblocking, it is recommended to transport liquid nitrogen to test whether it is unblocked. Do not use tapping to unblock. 3. Insufficient pressure Check whether the pressure in the liquid nitrogen tank is sufficient. If the pressure in the liquid nitrogen tank is too low, the pressure cannot be increased even if the pressure increase valve is opened. 4. Container leakage The container leaks and the vacuum is destroyed, which will also result in the inability to pressurize. It is easy to judge whether the container is leaking. You can observe the frosting phenomenon on the tank body. The location of a large area of frost is the leakage location. At this time, the jar can no longer be used normally. You can contact the manufacturer for after-sales treatment. In short, there are many reasons why the pressure does not rise after the booster valve of the self-pressurizing liquid nitrogen tank is opened. Check them one by one to find out and solve the problems.

In biological sample centers or scientific research institutions, there are a large number of cells, strains, vaccines and other samples that need to be cryopreserved. The scientific research of these samples is of great significance, and their safety cannot be ignored. In addition, there are requirements for batch management and data collection. Vapor phase liquid nitrogen tanks are often chosen over aviation aluminum Dewars. Vapor-phase liquid nitrogen tank, also known as "stem cell liquid nitrogen tank", is named after it is often used to establish stem cell banks. It is different from ordinary liquid nitrogen containers. It has two storage modes: gas phase and liquid phase. The sample storage method is unconventional and its working principle is break the usual. Sample storage methods in gas phase liquid nitrogen tanks: Partition management, gas phase preservation! The inner tank of the stem cell liquid nitrogen tank is divided into two areas. The upper area is for samples, which is the storage area for stem cells, embryos, bacteria, etc.; the lower area is for liquid nitrogen storage only and does not contain any samples. The bottom position, which is the liquid nitrogen storage area, is equipped with an evaporator to provide evaporated nitrogen for sample storage to cool down. The sample is only "close" to the liquid nitrogen, but does not touch it, and the volatilized low-temperature nitrogen is used to store the cells. Working principle of gas phase liquid nitrogen tank: The principle is actually very simple, such as the use of liquid nitrogen evaporation cooling mentioned above! When the nitrogen in the sample storage area is insufficient to support the sample demand, the bottom evaporator starts working to supply liquid nitrogen to the upper part. This has the advantage of avoiding sample cross-contamination. The reason why I donâ??t mention its other storage mode - liquid phase is because the liquid nitrogen reserve in the container is large, much higher than that of conventional liquid nitrogen containers, and the evaporation loss of stainless steel is higher than that of aluminum alloy. When storing in liquid phase, replenish the liquid. Frequent and troublesome, difficult to use, only gas phase storage is recommended. In addition, the gas-phase liquid nitrogen tank also has high dual-gallery vacuum + high thermal insulation performance, which reduces heat conduction, reduces the evaporation rate of liquid nitrogen, and maintains stable pressure inside the tank. The built-in intelligent control management system is used for real-time detection and abnormal warning of temperature, pressure and liquid level to ensure the stability of the tank and the safety of stem cells. If you have any needs, please contact KGSQ liquid nitrogen tank:
Currently, the methods of cell preservation are refrigerator and liquid nitrogen. When it comes to long-term storage, liquid nitrogen wins. However, conventional liquid nitrogen tanks need to constantly detect the liquid level, and the cells cannot be stored higher than the liquid nitrogen level, which is not conducive to long-term storage of cells. However, the "stem cell liquid nitrogen tank" that breaks the rules can do it! For long-term storage of large quantities of dry cell samples, it is ideal to use stem cell liquid nitrogen tanks by default. Why? 1. Storage temperature is -150~-196â?? For cells, the more comfortable storage temperature is -150â??~-196â??. Conventional liquid nitrogen tanks only have a temperature option of -196â??. Samples at this temperature are not in danger. The storage temperature of stem cell liquid nitrogen tanks changes with the sample area. The temperature difference in each storage area is 10�°C, which provides more options for cells. You can choose a more suitable temperature for cells to store. 2. Prevent pollution Another important point in cell cryopreservation, stable storage time and how to prevent contamination during storage. To stabilize the storage time, the stem cell liquid nitrogen tank adopts the characteristics of vacuum multi-layer insulation, electronic temperature control and liquid nitrogen dispersion, making the storage tank intelligent cooling and constant temperature process uniform and stable. To prevent storage contamination, you must know that cells become contaminated because they are in direct contact with liquid nitrogen. First, because the cryopreservation tube is not well sealed, liquid nitrogen enters through the gap. After taking out the test tube, there is a temperature difference and pressure difference between the inside and outside. Under the combined action of temperature and pressure, the tube explodes. Second, bacteria will enter the liquid nitrogen tank after it has been used for a period of time. These bacteria are likely to flow into the freezing tube with the liquid nitrogen and contaminate the sample. Stem cell liquid nitrogen tanks can prevent contamination because they can store liquid nitrogen and cells separately, avoiding direct contact between the two. At the same time, they can also use the low-temperature environment formed by the evaporation of liquid nitrogen for storage to avoid pipe explosions and cross-contamination. risk.
