Safety Exhaust Filter

exhaust filter with breakthrough detector
  • Prevents pollution of ambient air with volatile compounds
  • Large capacity and long lifetime
  • Break-through detector available, alerting users to saturation of the filter absorbent
  • Universal 1/4-28 connection - fit all VICI safety caps and VICI caps
  • Adapter to competitor products available

Our improved exhaust filter is the center of the VICI Jour safety program, ridding ambient air of solvent vapors which could adversely affect the health of lab workers. When placed on the waste bottle of an HPLC system, the specially-treated absorbent filters out nearly all organic solvent vapor evaporationg out of the waste solution.

With 65 g of absorbent, our filters have a larger capacity than competing brands. Typical lifetime is up to 10 months* for methanol, and up to 8 months* for acetonitile.

breakthrough detector

The optional break-through detector recognizes trace amounts of acetone, acetonitrile, aliphatic and aromatic hydrocarbons, ethanol, ethyl acetate, methanol, methylene chloride, and THF. When the absorbent is saturated, break-through is indicated by a color change in the detector from orange/pink to dark purple. A small charcoal filter absorbs the vapors after they pass the detector.

*Based on results of our tests (water/organics = 50/50; flow rate 1.0 ml/min during the day, 0.5 ml/min overnight, 0.1 ml/min during weekends).

TECH TIPS

  • Larger capacity = longer lifetime = lower costs
  • As a general rule, halving the flow rate doubles the lifetime at constant composition and temperature. Doubling the flow rate halves it.
  • Acetonitile and water form an "azeotropic" mixture at 85% acetonitrile. Due to this physical property, the vapor of an acetonitrile/ water mixture always corresponds to the 85/15 mixture.This explains the non-linearity of the lifetime for acetonitrile compared to methanol.
