CA Membrane Filter
Product Description

Microlab Cellulose Acetate membranes combine high flow rates and thermal stability with very low adsorption characteristics and are therefore excellently suited for use in pressure filtration devices. The membrane with 0.2µm is the filter of choice for sterile filtration of aqueous solutions, such as nutrient media, buffers and sera. The results of publications on adsorption are difficult to correlate, as mostly different test substances, conditions and detection methods were used, and the membranes were tested without previously being sterilized.


•    Bacterial removal
•    Biosensors
•    HPLC flowing particle removal
•    Drug filtration
•    Organic solvents filtration    
•    IV filters
•    Lateral flow assays
•    Particulate removal

Products Feature

Ideal for use in general filtration or medical assays
•    High wick rates (lateral flow), substances move quickly through the membrane
•    Uniform pore structure provides consistent flow and diffusion rates
•    Superior strength, withstands aggressive handling or can be used with automated equipment without breaking or tearing
•    Exceptional sensitivity, detects low-level components
•    Lot-to-lot consistency, quality checks produce dependable results every time
