Introduction: 4-hydroxyethyl piperazine ethosulfonic acid (HEPES) is an important hydrogen ion buffer, which has a good buffer ability in the pH range of 6.8 to 8.2, and can control a constant pH for a long time. Using a concentration of 10 ~ 50mmol/L, the general culture medium containing 20mmol/L 4-hydroxyethyl piperazine taurine can have a good buffer capacity, and has no toxic effect on cells. Application: HEPES (4-hydroxyethyl piperazinethesulfonic acid) is a non-ionic amphoteric buffer with high polarity, and is inert to a variety of chemical reagents and enzymes. It does not participate in and interfere with the process of biochemical reactions, and has no inhibitory effect on enzyme chemical reactions. Therefore, it can be used specifically for the research of proteins and enzymes that are highly volatile and ph-sensitive to organelles and very volatile. Buffer solution preparation: (1)hepes buffer can be directly added to the prepared culture medium according to the desired concentration, and then filtered to remove bacteria. 2.38 g HEPES was added to each 1000ml of culture medium, the pH was adjusted to 7.2 with lNNaOH after dissolution, and the bacteria were removed by filtration before use. At this time, the concentration of HEPES was 10mmol/L. (2) 100x storage solution (lmol/L) could also be prepared. Before use, 99ml culture solution was added to lml storage solution, and the final concentration was 10mmol/L. lmol/L (100x) hepes buffer was prepared as follows: 23.8gHEPES was dissolved in 90ml double distilled water, the pH was adjusted to 7.5-8.0 with lNNaOH, and then the water was fixed to 100ml, filtered to remove bacteria, divided into vials (2ml/ bottle), and stored at 4�ºC or -20�ºC. Purpose: 1.Biological buffer; Reaction buffer, prehybridization buffer and hybridization buffer for isolation and analysis of RNA nuclear fraction; For RNA with T4RNA 2.Molecular biology grade is used for RNA3' -end labeling with T4 RNA ligase 3.Cell-cell adhesion, short-term cell aggregation culture, cleaning of tissue and cell buffer

Speciality valve is a largest Cryogenic valve manufacturer in India. Cryogenic valves, as their name , are intended for use in extremely cold environments. Companies that work with liquefied natural gas LNG or compressed natural gas CNG use them the most CNG. The oil and gas industry, for example, regularly employs cryogenic temperature ranges beginning at 238 degrees Fahrenheit 150 degrees Celcius .Furthermore, some gases are characterised as 'cryogenic' not because of their temperature, but because compressing their volume requires more than a simple pressure rise. Cryogenic valves are designed to transmit and store cryogenic gases in a safe and efficient manner. Cryogenic Valves Working To keep cryogenic gases or other medium secure and safe, cryogenic valves are kept in a naturally closed condition. A cryogenic valve is often designed to respond to high pressure by opening the valve, allowing gas or other media to flow freely through it. This open flow will continue until the pressure drops again, at which time it will swing back and close with a special metal seat bubble tight shutdown to prevent any leakage. The cryogenic valves have the device drivers as bevel gear, pneumatic, handle, or electric. The design standards used for these valves are API 602, BS 6364, and API 600. Being used in cold applications, cryogenic valves mainly hold impxortance in the factories that deal with compressed natural gas. These valves help to store the heavy cryogenic gasses efficiently and safely. When you search for the best cryogenic valve supplier in , we would be topping up the list. Thus, get in touch with us today. Cryogenic Valve is use in many industries such as Medical Industry. Aerospace Industry. Air Separation Plants. Petrochemical Industry. LNG Storage Industry. Types of cryogenic valve Cryogenic gate valve Cryogenic globe valve Cryogenic ball valve Cryogenic check valve Cryogenic butterfly valve Advantages of Cryogenic Valves Built to open under high pressure to allow free flow of gases before the pressure drops, at which point it seals with a metal seat to prevent further leakage. Cryogenic Globe valves provide Long-term sealing capacity. Cryogenic valves come in a number of shapes and sizes, allowing them to work in a variety of pressure levels. Therefore, they are great for whatever type is needed. Description Body materials stainless steel SS304, SS316, CF8M, SS316L, SS904L Size 12 12 Class 150 1500 PN10 PN450.
