Cosmonice Filter

Prefiltration Tools / Syringe Filters for HPLC

Cosmonice Filter is able to remove the dust (microparticles, precipitates, colloid substances, and so on) from sample, to minimize adverse effects for the injection sample, to extend the life of column, and to keep the stable data. There are two types of Cosmonice Filter as stated below.

 

W Series (Aqueous Solution)

W series are installed new material of low-adsorptive and low-extractive durapore-filter (poly vinylidenedifluoride, PVDF) which can be used for the various solvents. So they are able to minimize the loss of the proteins in the small amount of sample, and to prevent from secondary contamination at the prefiltration.

 

S Series (Organic Solvents)

S series are installed teflon-filter (poly tetrafluoroethylene, PTFE) shows strong resistance for solvents, acids, and alkalis. It is the best for the prefiltration of the sample extracted with solvents such as chloroform, tetrahydrofuran, and so on
