A significant drawback of chemical CO2 absorbers is the production of compounds harmful to patients.  This results in increased cost and environmental impact, including the daily disposal of special waste.

low-flow anesthesia cannot be safely achieved using traditional chemical CO2 absorbents

"In order to address the build-up of neuro and nephro-toxins, the industry solution is to use higher fresh gas flow rates"

(Bengtson JP 1988, Cotter SM 1991, Feiss P 1990)

"Over 80% of the anesthetic gases are wasted when a fresh gas flow of 5.0 L/min is used. Several studies show that the use of low […] flow anesthesia techniques can dramatically reduce the annual costs of volatile anesthetics" (Bengtson JP 1988, Cotter SM 1991, Feiss P 1990)

Sustainable management of general anesthesia is a growing concern.  Continually diluting anesthetic circuits, and the disposal of chemical granulate are serious environmental problems.

our aim is ...

increased patient safety

no harmful products created

cost savings

savings of anesthetic agent use


easily clicks in place of GE or Dräger catridges with a conveninently low replacement cycle


fully recycable with no harmful substances

low-flow anesthesia

the absence of harmful products allows for a significant reduction in anesthetic agent waste

environmental stewardship

reduced anesthetic agent waste into the atmosphere reduces global warming
