Patterson Scientific offers new precision flow-rate and temperature compensated vaporizers specifically calibrated for use with our SAS-3 anesthesia systems. The new 3EX is an extended capacity (250ml) vaporizer that has a 10 year warranty contingent upon a 2 year service cycle. Larger capacity for liquid anesthetic means filling the vaporizer less often which, in turn, reduces exposure to anesthetic gases. Both isoflurane vaporizers and sevoflurane vaporizers with either funnel fill or pin index/key fill systems are available.
