GVS capsules are disposable filtration units designed for the removal of particles or bacteria from aqueous or solvent solutions and gas streams. They are ready to use, eliminating the need to disassemble, clean and reassemble filter housings. GVS capsules contain no glue or surfactants and feature serial layer filter design for increased throughput and extended life. Two upstream vents are included to facilitate venting in any position. All capsules containing membrane media are preflushed with purified water to reduce extractables. GVS capsules pass class VI toxicology testing and are integrity tested prior to shipment. Capsule filters are available in sterile and non-sterile versions. -
Features and Benefits • High range of chemical compatibility: Resistant to a wide range of chemicals • Smooth, thin, glass-like surface: Captures all particles on the surface larger than the pore size • Precise pore size and density: Provides flow control for liquids moving through the membrane capturing 100 percent of cells larger than pore size • Low extractables: Ensures tests will be clean promoting consistent results • Low protein binding: Low binding prohibits absorption of cells being filtered • Negligible absorption/adsorption:Maximizes critical solution recovery -
GVS PCTE Membrane is made from a thin, microporous polycarbonate film material. It is ideally suited for use in blood assays and high-purity and general filtration. Though polycarbonate is hydrophobic, the membrane is treated with a wetting agent to make it hydrophilic. Features and Benefits • Smooth, thin, glass-like surface: Planar surface makes it ideal for particle identification by microscopy • Superior strength: Tensile strength of 207 bar (> 3000 psi) maintains pore size and density, and will not stretch • Low extractables: Ensures tests will be clean promoting consistent results • Low protein binding • Negligible absorption/adsorption:Maximizes critical solution recovery -
GVS polypropylene membrane filters are composed of pure polypropylene with absolute pore size ratings. These filters offer broad chemical compatibility allowing its use with aqueous and organic solvent samples. The polypropylene filter has extremely low extractable levels designed to provide accurate, consistent analysis results for sensitive ion chromatography applications while prolonging column life. GVS polypropylene filter is the preferred filter membrane for HPLC applications where the detection levels are below 230 nm. The filters also exhibit negligible protein binding which, is essential for maximum sample recovery of critical, small volume protein samples. -

GVS Nylon Filtration Membrane is internally supported with an inert polyester support web giving it added dimensional strength and stability that prevents cracking, tearing, curling and breaking. This added strength and durability is advantageous during usage that involves aggressive handling or automated equipment. A naturally hydrophilic membrane, GVS Nylon Filtration Membrane does not require wetting agents that can interfere with biological processes. This membrane has porosity of 70/80% for high diffusion and low-flow resistance. -
This strong, microporous film asymmetric membrane is constructed from a high-temperature polyethersulfone polymer that is acid and base resistant. Its strength and durability are advantageous during usage that involves aggressive handling or automated equipment. GVS PES Filtration Membrane is naturally hydrophilic without added wetting agents and has low extractables. Due to its inherent uniform porosity and controlled pore size, GVS PES Filtration Membrane efficiently removes particulates from solutions during general filtration. Additionally, its low protein and drug binding characteristics maximize recovery of critical drugs used in I.V. therapy, chemotherapy, and open-heart surgery. -
GVS Life Sciences MCE Filtration Membranes are composed of a mixture of inert cellulose nitrate and cellulose acetate polymers. The uniform microporous structure of these filters provides the fastest flow rates and highest throughputs available in a membrane filter. Because they are biologically inert, GVS Life Sciences MCE Filtration Membranes are ideal for a wide range of clarification, sterilization and analytical applications such as: microbiological analysis, clarification or sterilization of aqueous solutions, industrial hygiene applications, silt density index and particulate-matter analysis. For gravimetric analysis using ashing techniques, GVS Life Sciences MCE Membranes yield a residue or less than 0.045% of their initial weight. They are hydrophilic with a noncytotoxic wetting agent and yield extractable levels of less than 4% of their weight. These membranes are autoclavable at 121°C (250°F) for 20 minutes. Sterilized product lifetime is 24 months from sterilization date. -
GVS CA Filtration membranes are composed of pure cellulose acetate that is internally supported by an inert polyester web. This web gives each membrane exceptional strength to prevent cracking, tearing, breaking and distortion when handled or creased. The resulting membrane has dimensional stability that can withstand autoclaving or steam sterilizing leaving the membrane unaffected in temperatures up to 274ºF (135ºC). The exceptional dimensional strength and low binding characteristics of GVS CA Filtration Membranes provide higher throughputs than competitive offerings and reduce the number of filter changes needed during proteinaceous solution filtering. -
