Phenex Glass Fiber Prefilter + CA (GF/CA) Syringe Filters
Phenex glass fiber prefilter + CA (GF/CA) syringe filters are excellent for the filtration of tissue culture media and general biological sample filtration

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.

An integrated syringe filter unit containing an inert borosilicate glass fiber prefilter and a CA membrane. Outlet connection is luer lock.

Recommended Use
Filtration of tissue, cultures, media, and buffers that are highly viscous or contain high concentrations of particulate matter


Application / Sample* Recommended Filter** First Alternative
Tissue Cultures, Media, Buffers GF/CA PES

* 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.
