Cassette Blanks
Cassette blanks are two or three section housings for filters. They hold the filter securely in place during sampling and are ideal for personal sampling.
Opaque filter cassette blanks are designed to handle light-sensitive compounds such as PNA (Paraffins, Naphthenes and Aromatics) hydrocarbons.
All SureSeal cassettes are inspected to meet a vacuum leak test of <1 inch Hg delay per 30 seconds when subjected to 24 inches Hg vacuum and a pressure decay of 1 psi per 30 seconds when subjected to 5 psi pressure. SureSeal Leak-free cassettes require the use of a SureSeal Cassette Opener.
