Prefiltration Tool for Liquid Chromatography

Cosmonice Filter Series

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 (polymvinylidenedifluoride, 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.

Cosmospin Filter 

• Dimensions: Diameter 10.6 mm x Length 45 mm
• Membrane: Omunipore Hydrophilic PTFE
• Sample Reservoir and Sample Vial: Polypropylene

Cosmospin Filter can easily remove the particles and precipitations from the sample only by using a centrifugal machine. Moreover, it is adopted omunipore hydrophilic PTFE membrane filter with wide-ranging chemical resistance. So it is the best for prefiltration of HPLC. According to the pore size, G (0.2 μm) and H (0.45 μm) are available.
