Cellulose Acetate (CA) Membrane
CELLULOSE ACETATE (CA) MEMBRANE Sterlitech Cellulose Acetate membrane is a supported, hydrophilic membrane that is naturally low binding. It is ideal for use in enzyme loading and latex bead entrapment assay formats or as a pre-filter.
FEATURES AND BENEFITS
• Ideal for use in enzyme loading and latex bead entrapment assays or as a pre-filter
• Superior strength, can withstand aggressive handling or be used with automated equipment without breaking or tearing
• Low protein binding, BSA binding capacity of 3.8ug/cm2 prohibits absorption of cells being filtered
• Low extractables, ensures tests will be clean with consistent results • Exceptional sensitivity, detects low-level components • Hydrophilic, wets out rapidly without wetting agents that can interfere
with biological processes • Lot-to-lot consistency, quality checks ensure consistent flow and
diffusion rates for dependable results every time • Nonlysing of cells, prevents corruption of critical solutions

EXCEPTIONAL STRENGTH AND BINDING FOR IMPROVED PERFORMANCE Sterlitech Cellulose Acetate membrane filters are composed of pure cellulose acetate that is internally supported by an inert polyester web. This web gives each filter 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 135°C (274°F). The exceptional dimensional strength and low binding characteristics of Sterlitech Cellulose Acetate provide higher throughputs than competitive offerings and reduce the amount of filter changes needed during proteinaceous solution filtering. Its uniform pore size and consistent flow rates ensure reliable performance for use in enzyme loading and latex bead entrapment assay formats or as a pre-filter.

Glass Fiber Membranes Glass fiber filters can be used to extend the life of a final filter as a prefilter or they can be used alone for low cost sample clarification. The filters are available with or without binders. Binders are used to increase the strength of the membrane and also reduce media migration. Binder-free membranes are able to withstand higher temperatures. FEATURES AND BENEFITS
• Type GC-50 meets the requirements for suspended solids testing, as described in Standard Methods for the Examination of Water and Wastewater, current edition.
• Reduce filtration costs and premature clogging when filtering difficult-to-filter or highly contaminated solutions.
• Extend filter life and make fewer final filter changes with high capacity prefilters.
• Eliminate sample contamination. Binder-free borosilicate glass fiber has no added extractables.
• Filter a wide range of particulate loads and viscous solutions with a selection of filter thicknesses to choose from.
• Excellent wet strength for each handling and filter integrity.
