Cosmonice filter
Injection of samples containing particulates (microparticles, precipitates, colloid substances) will clog HPLC columns, shorten injector life, and result in extensive maintenance on pumps. Cosmonice filters are used to remove particulates from samples and prolong the life of HPLC system components. There are two types of Cosmonice filters as stated below.
W series (Aqueous solution)
W series are installed with low adsorption hydrophilic durapore filter (polyvinylidenedifluoride, PVDF). W series can be used with both aqueous and organic solvents. They are best suited for prefiltration of protein and other biological samples.
S series (Organic solvents)
S series are installed Teflon filter (polytetrafluoroethylene, PTFE) with strong resistance to organic solvents, acids and alkalis. They are best suited for prefiltration of samples with aggressive organic solvents such as chloroform and tetrahydrofuran.

Cosmospin filter
Cosmospin filters are used to remove fine particles and precipitates from samples by centrifugation. They utilize Omnipore hydrophilic PTFE membrane filter, which has a wide range of chemical resistance. Cosmospin filters are the best choice for HPLC sample filtration. Two pore sizes, G (0.2 m) and H (0.45 m), are available.
