virus transport medium-inactivated typeusing high concentration of guanidine can quickly inactivate and preserve respiratory pathogens, so that the sample lost infectivity.Inactivated samples can be matched with a variety of viral DNA/RNA extraction kits, M32/M96 nucleic acid extraction apparatus for rapid nucleic acid extraction, and respiratory pathogen PCR detection kit for rapid detection, the specificity and sensitivity are not affected.Virus preservation fluid has many functions:1. The operation is simple, no liquid distribution is needed, the system contains highly effective virus lysate, the virus is immediately inactivated after sampling, and the risk of secondary infection is effectively prevented.2. Contain nucleic acid Rnase enzyme inhibitor, protect the viral nucleic acid from degradation to a greater extent, and greatly improve the efficiency of nucleic acid extraction.3. The product can be stored at room temperature for 12 months before sampling, and the sample can be stored at room temperature for one week after sampling, with good tightness, which is convenient for storage and transportation and saves transportation cost.Since 2005, desheng has been committed to the research of sample collection and in vitro diagnosis and the production and sales of related raw materials.Welcome to inquire!

carbomer 980 - is a commonly used wave series materials, carbomer is acrylic bonded allyl sucrose or pentaerythritol allyl ether polymers, usually in the form of loose white slightly acid powder, lower dosage can produce efficient thickening effect, which were very wide viscosity range and different rheological property of emulsion, cream, gel and transdermal preparations.different card's performance is slightly different, different models for different viscosity, a short rheological or long rheological said, such as: cabo 940 has a short rheological properties, in 0.5% of 63000 mpa viscosity. S, proper the product with high viscosity, cabo 941 has long rheological properties, in 0.5% viscosity reached 7500 mpa. S suitable for low viscosity products, carbomer corresponding models have no resistance to ion and ionic resistance performance.carbomer 980 has good thickening, high transparency, high viscosity, and strong suspension.carbomer 980 is widely used in daily chemical products, such as skin lotion, cream, transparent gel products, transparent skin gel, hair styling gel, shampoo, shower gel and disposable disinfection gel.notes:1. If the solution is used in the usual way, carbomer cannot be stirred when added to the water. Stirring while adding will cause carbomer to form a white water ball, and bubbles will be difficult to eliminate after neutralization;2. After the neutralization of carbomer, long time stirring or high shear stirring will cause viscosity loss;3. The presence of electrolyte will reduce the thickening efficiency of kapo resin;4. Long-term ultraviolet irradiation will reduce the viscosity of kapo resin.desheng technology is specialized in the collection of acrylate series of blood vessel separation adhesive, capom980, caps, mops and other surfactants and biological buffers.
