x-ray quality assurance or calibration devices

White 1+PAC White gridded discs are designed for the recovery and retention of E. Coli bacteria in water / waste-water analysis as well as other microbiological tests.

GVS MCE Filtration Membranes are composed of a mixture of inert cellulose nitrate and cellulose acetate polymers. The uniform microporous structure of these filters provides the fastest flow rates and highest throughputs available in a membrane
