HEPES (4-hydroxyethyl piperazine ethanesulfonic acid) is a kind of hydrogen ion buffer with pH value ranging from 6.8 to 8.2. In the process of cell culture, we often need HEPES buffer. It is a kind of weak acid. In the open culture condition, if HEPES is added, it can prevent the increase of pH oxidation in the culture medium and maintain the pH at about 7.0. The final concentration of HEPES buffer was 10-50 mmol / L, which had no toxic effect on cells. Generally, 20 mmol / L HEPES can achieve buffering capacity. Since we often use it in cell culture medium, what are its advantages in cell culture medium?
Most of the cells need pH 7.2-7.4, but the optimal pH for cell culture varies with different cell types. Fibroblasts prefer higher pH (7.4-7.7), while the subculture and transformation cell lines need acid pH (7.0-7.4). HEPES is a kind of nonionic amphoteric buffer, which has good buffer capacity in the range of pH 7.2-7.4. The advantage of this method is that it can maintain a relatively constant pH value in open culture or cell observation. Under this condition, the cover of the cell culture bottle should be tightened to prevent a small amount of carbonate needed in the culture medium from scattering into the air.
HEPES produced by Desheng is white crystal powder, with main content of 99.50%, iron ion 5ppm, sulfate 0.05%, and heavy metal residue (PB) 10ppm. Can provide trial sample powder, self-made solution for testing.

What is pe/pp bicomponent fiber? PE/PP bicomponent fiber is a type of synthetic fiber that is made up of two different polymers, polyethylene (PE) and polypropylene (PP), which are combined in a single filament. What are the advantages of using PE/PP bicomponent fiber in textiles? PE/PP bicomponent fiber offers several advantages in textiles, including improved strength, durability, and moisture management. It also provides a softer feel and can be used in a variety of applications, such as sportswear, outdoor apparel, and home textiles. What are some common uses of PE/PP bicomponent fiber in the textile industry? PE/PP bicomponent fibers have several advantages that make them popular in the textile industry. Some of these advantages include: Improved Strength: PE/PP bicomponent fibers have a higher tensile strength than regular fibers, making them ideal for use in high-stress applications. Enhanced Durability: These fibers are resistant to wear and tear, making them ideal for use in products that need to withstand daily use. Improved Comfort: PE/PP bicomponent fibers have a soft texture, which makes them comfortable to wear against the skin. Moisture Management: These fibers are hydrophobic, which means they repel water and moisture. This property makes them ideal for use in products that need to stay dry. Some common uses of PE/PP bicomponent fiber in the textile industry include: Clothing: These fibers are often used in the production of sportswear, outdoor clothing, and other products that require enhanced durability and moisture management. Home Textiles: PE/PP bicomponent fibers are used in the production of carpets, curtains, and other home textiles that require enhanced strength and durability. Nonwoven Fabrics: These fibers are used in the production of nonwoven fabrics, which are used in a wide range of applications, including medical products, hygiene products, and filtration materials. Overall, PE/PP bicomponent fibers offer several advantages that make them a popular choice in the textile industry for a wide range of applications.
Advantages: It is uniformly depressed anti-adhesive, with excellent film-forming properties; Polymerization of continuous device production makes the quality high and stable.

PE Granules High density polyethylene (HDPE) for non-toxic, tasteless, no smelly white particles, melting point is about 130 �° C, relative density of 0.941 ~ 0.960. It has good heat resistance and cold resistance, chemical stability, but also has high rigidity and toughness, good mechanical strength. Dielectric properties, environmental stress cracking resistance sex also is good. Low DENSITY POLYETHYLENE (LDPE), commonly known as high-pressure POLYETHYLENE, is mainly used in plastic bags and agricultural film due to its LOW DENSITY and the softest material. Linear Low Density Polyethylene (LLDPE) is a copolymer of ethylene and a small amount of advanced olefin in the presence of catalyst.LLDPE is similar to LDPE in appearance, with poor transparency and good surface gloss. LLDPE has the advantages of low temperature toughness, high modulus, bending resistance and stress cracking resistance, and good impact strength at low temperature. We have a wide range of grade PE materials with different physical properties. If the table does not meet your requirements, please feel free to consult us we will try our best to meet all your requirements for plastic granules.

XPS (Extruded Polystyrene) foam insulation boards are commonly available in 4x8-foot sheets. These sheets are used for various insulation applications in construction, such as insulating walls, roofs, and floors. XPS insulation is known for its closed-cell structure, which provides good thermal resistance and moisture resistance.
PVC resin is a polymer compound formed by polymerization of vinyl chloride monomer (VCM), and its structure unit is [CH2-CHCL]n. polymerization degree is usually 590-1500. According to the content of residual polyethylene monomer in PVC resin can be divided into: industrial grade, food hygiene grade and medical grade. The appearance of PVC resin is white powder. PVC resin SG3 SG5 SG8 is flame-retardant (flame retardant value above 40), high chemical resistance (resistant to concentrated hydrochloric acid, 90% sulfuric acid, 60% nitric acid and 20% sodium hydroxide), mechanical strength And the advantages of good electrical insulation. But its heat resistance is poor, with a softening point of 80�°C, it starts to decompose and change color at 130�°C, and precipitate HCI. Application: It is widely used in the production of polyvinyl chloride boardy leatheroid, paint and adhesive agents, paint and adhesive. Packing: 25kgs two layers draft paper bag or 1000kgs PP bag.
