Laboratory Filtration

Disposable sterile Cellulose Acetate hydrophilic filtration media syringe filters are individually blister packed and feature Luer-Lok™ and pressure fitting. They are ultrasonically bonded for reliability and the filter media type is clearly inscribed on barrel. Excellent unit-to-unit and lot-to-lot reproducibility and consistency. The unique concentric funnel shaped barrel increases volume and decreases back pressure. Very low binding capacity for proteins. Cellulose acetate is nitrate-free making it suitable for groundwater & EPA ASTM's. Use for filtration under sterile conditions ...

Disposable non-sterile PES / Polyethersulfone hydrophilic filtration media syringe filters feature Luer-Lok™ and pressure fitting. They are ultrasonically bonded for reliability and the filter media type is clearly inscribed on barrel. Excellent unit-to-unit and lot-to-lot reproducibility and consistency. The unique concentric funnel shaped barrel increases volume and decreases back pressure. High filtration flow rates and an inherently low affinity for proteins. Low extractables. Use for introduction of additives into tissue culture vessel. Certified for Ion Chromatography. Use for ...

Biologically inert mixtures of cellulose acetate and cellulose nitrate result in membranes with a smoother and more uniform surface than pure nitrocellulose filters. MCE is easier to handle and less likely to crack and fracture than traditional CN membranes. Pure surface, no additional smoothing treatment or surfactants.Non-sterile version is bright white with an accurate pore structure and highly regulated density for accuracy. Medium-fast flow rates with reproducible loading capacity. Clean-edge processing ensures easy separation from stack and less curl. Autoclavable.Use for ...

Grade TSS is a Binderless high efficiency (HEPA type) filter medium with particle retention of 1.50um. Liquid filtration properties have been specifically designed for EPA Methods 2540C and 2540D for testing dissolved and suspended solids in water and wastewater. High flow rate with high capacity. Binderless borosilicate glass fiber media has no added extractables to aid in the elimination of sample contamination. Excellent wet strength. Other common applications include gravimetric analysis of air pollutants, membrane support pads, membrane prefilters, clarification of reagent and buffer ...

Grade VSS is a binder free material used in high heat applications beyond typical borosilicate glass blends. Suited for determination of Fixed & Volatile Solids Ignited at 550°C Method 2540E. Low fiber shedding improves quality assurance of test results and low percent weight loss when used in gravimetric tests. Particle retention of 1.50um and high loading capacity due to high surface area and complex pore structure. Compliant with requirements of standard methods 2540C & 2540D and EPA Method 160.2 for establishing water quality in suspended solids content. Widely used in air ...
