Disposable Filtration Products
GVS Laboratory Filtration Products series, including syringe filters and Vacuum Filters, are designed specifically for the filtration of culture media and organic solvents in research and industrial laboratories They are purpose-built with features designed to bring the highest levels of performance and purity to your research A variety of membrane types and membrane areas are for choice that offer the wide applicability range for separation and purification of most liquid samples to meet different laboratory needs. The filtration products should be driven by syringes or vacuum pumps. All the products are manufactured with high quality material (ABS, PP or GPPS) and by provented technique, which assure them work under pressure and still hold integrity.
Tips on choosing membrane MCE (Mixed Cellulose Ester)
By the mixture of nitrocellulose and cellulose acetate, hydrophilic, chemical compatibility, low protein adsorption. The use temperature can not be higher than 40°C, the optimum pH range is 3-6. Particle analysis, particle removal, biochemical analysis, HPLCsample preparation for general media and aqueous solutions. Can not be used to filter ethanol and alkaline solution.
Nylon
Providing a broad range of chemical compatibility of the filtration of either aqueous or organic solvents, hydrophilic, can be used in a broad pH range.
PVDF (Polyvinylidene fluoride)
Extremely low protein-binding, for filtration of non-aggressive aqueous and mild organic solutions, or were maximizing protein recovery is important
PES (Polyethersulfone)
Low-affinity for proteins and extractable with substantially faster flow rates than PVDF; suitable for pre-filtration and filtration of buffers and culture media.
PTFE (Polytetrafluoroethylene)
Extremely strong chemically resistant and is compatible with various sterilizing methods; ideal for gas and in organic or organic samples in aggressive environments.
CA
Lowest binding material available Hydrophilic and high throughput Strength and dimension stability Uniform pore structure.
