Zefon match-weighed cassettes eliminate the user's inconvenience of pre-weighing filters for gravimetric analysis. Each cassette contains 2 filters which are matched in weight. After sampling, the user will weigh both filters. The difference in weight of the two filters will determine the sample amount.
Zefon uses the best in filter weighing technology to produce premium quality match-weighed cassettes. Our process includes preloading under strict environmental controls to ensure reproducibility - and provides the user with a quality product at a competitive price.
