Whatman VACU-GUARD 150 Gas Traps
Manufacturer: Cytiva
The VACU-GUARD line of filter devices combine the best of three classic chemical traps with proven vacuum protective (hydrophobic) PTFE membrane. The PTFE membrane is built into a pleated cartridge and is permanently fuse bonded inside the base of the capsule. These types of chemical traps have been recommended by Menniger and Vilardi for protection of vacuum pumps and the environment, from their exhaust, when used to "polish" incoming air from an evaporation system. The activated carbon traps are recommended for organic vapors. Anhydrous calcium sulfate (molecular sieve) traps are recommended for organic and alkaline air streams. Silica aluminate zeolite (dessicant) traps are recommended for acidic air streams. The hydrophobic filter cartridge using pleated PTFE membrane is inside the housing and fuse bonded to the outlet of the capsule. This stops aqueous solutions and 99.99% of particulates 0.1µm in air/gas. Inlets of these traps are ½" stepped barb connectors. Outlets are stepped barb connectors that will accept 3/8" to ½" tubing sizes.
