醋酸纤维素膜(CA)具有高流速、强热稳定性以及低吸附等优点。0.2μm的滤膜非常适合于水溶液、缓冲液、血清和培养基的除菌过滤。0.45μm的滤膜非常适合于HPLC的流动相过滤。关于得到膜吸附的公开结果是比较困难的，其与过滤的物质、过滤的条件和采用的测定方法以及被测定的膜没有被预先除菌有关。

Aisimo 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.

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

Feature and Specification
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
