Gravimetric analysis samples require filters to be weighed both before and after sampling to determine the amount of contaminate collected. Zefon® match-weighed cassettes eliminate the need of weighing filters before sampling by providing two filters which are matched in weight. The top filter collects particulate and the bottom filter serves as a control. After sampling, both filters are weighed and the difference in weight equals the amount of contaminate collected. 

Features
• Each cassette labeled with serial number
• Color coded to indicate filter type
• Preloaded - ready to use

*Limited shelf life
