Each ductless fume hood will have a magnetised certification label outlining the certification number, the chemicals approved for usage, the filter lifetime and means of determining filter saturation
Erlab, the inventor of the ductless fume hood in 1968, introduces an improved service - the Captair ValiQuest.
Its accredited laboratory will review all existing and potential client chemical handlings to certify carbon filter lifetime, toxic grams retained in the carbon, evaporation rate and method of determining filter saturation.
Each of Erlab's Captair ductless fume hoods will have a magnetised certification label outlining the Erlab certification number, the chemicals approved for usage, the filter lifetime and means of determining filter saturation.
A government test report certifies Erlab's filtration efficiency at 99.999% in keeping the user at 1% of Osha levels.
Erlab's book, the Captair Chemical Listing, documents the filtration efficiency of the over 650 chemicals found in Osha's Niosh guide.
Captair ductless fume hoods exceed Osha, Ansi, Afnor and CSA standards, it says.
