Gravimetric analysis samples require filters to be weighed both before and after sampling to determine the amount of contaminate collected. Zefon® pre-weighed cassettes eliminate the inconvenience of pre-weighing filters by providing the filter weight on each cassette prior to sampling.

Features
• Each cassette is labeled with weight and serial number
• Use of pure homopolymer PVC filters provides excellent weight stability
• PVC filters specially designed with no silica and low ash properties

*Limited shelf life
