Phenex Glass Fiber Prefilter + CA (GF/CA) Syringe Filters

Broadly Used in Biological Sample Filtration

Cellulose Acetate (CA) membranes exhibit ultra-low protein binding and are broadly used in the filtration of biological samples. This filter also incorporates a glass pre-filter. Phenex-GF/CA membranes are excellent for filtration of tissue culture media, general biological sample filtration, and clarification.

* Removal of high particulate matter with a glass fiber prefilter is critical before any drug, tox, or dirty environmental sample is filtered to ensure the highest syringe filter membrane performance.
** For high load and particulate-laden samples you may consider placing a Glass Fiber (GF) prefilter, either integrated with the membrane as one unit (Phenex- GF/NY or -GF/CA) or in series with the membrane syringe filter of your choice. Generally, 0.45 μm porosity filters are used to remove particulates from samples and mobile phase solutions. For sterile-filtration, a 0.20 μm porosity filter can be used.
