TrapIT Universal ¼ -28 connection Chemical Exhaust Filter prevents volatile compounds (known to affect health and safety adversely) from entering the laboratory from the TrapIT system.
The large capacity 65g absorbent component filters out nearly all evaporating organic solvent vapours. The optional colourimetric indicator picks up trace amounts of acetone, acetonitrile, aliphatic and aromatic hydrocarbons, ethanol, ethyl acetate, methanol, methylene chloride, and THF. They are designed to provide real-time indication of vapours' breakthrough, when the absorbent is saturated, a colour change in the detector from orange/pink to dark purple. A small charcoal filter absorbs the vapours after passing the sensor making this both an ideal and necessary safety addition to the laboratory.
