- Leak-free design contains all the samples collected
- Use with 37-mm diameter membranes
- Two-piece housing
- Conductive black polypropylene construction
- Becomes electrically conductive when grounded
Use two-piece housings for closed face sampling applications. With 35% less surface area than three-piece housings, there is less surface area for the contaminants to cling to, so more contaminants will end up on the filter membrane. Three-piece housings feature one spacer ring while the four-piece housings feature two spacer rings, separating the inlet from the filter media. Four-piece model allows for a center filter placement to be placed in the shoot-through FTIR cassette for on-site analysis. Both three- and four-piece housings are suitable for open and closed face sampling applications.
