Syringe filter

Eternalwater KZ series--syringe filters are suitable for prefiltration of small amount of samples in the laboratory, clarification and removal of particles, and sterilizing filtration of liquids and gases. Low adsorption to samples ensures maximum sample recovery. The housing is made of polypropylene (PP), which has excellent chemical stability. A variety of filter membranes and specifications are available.
