AIMS™ CO2 Flowmeter

CO² Flowmeter

 

Calibrated to accurately deliver CO2 to ANY Chamber.

Small profile with an easy to set Flow-Rate and 3-way ball valve for quick chamber fill when needed.

Barb fitting for connecting to 5/16" or 1/4" ID hose. Wall-mount option.

Example Calculations for 20% Chamber Vol/min
Large Rat Cage
19” x 10” x 8” = 1520 in3.
1520 in3 x 0.20 = 304 in3 (flow rate wanted 304 in3/min).
304 in3/min divided by 61.024 = 4.98 l/min AIMS CO2 flowmeter setting.

AIMS CO2 Chamber (cylinder)
? x Radius2 x Height
3.14 x 4”2 x 7” = 352 in3.
352 in3 x 0.20 = 70 in3 (flow rate wanted 70 in3/min).
70 in3/min divided by 61.024 = 1.15 l/min AIMS CO2 flowmeter setting.

AVMA Guidelines for CO2 Euthanasia
General recommendations—Carbon dioxide is acceptable......using a gradual fill method is less likely to cause pain due to nociceptor activation by carbonic acid prior to onset of unconsciousness; a displacement rate from 10% to 30% of the chamber volume/min is recommended......... The practice of immersion, where conscious animals are placed directly into a container prefilled with 100% CO2, is unacceptable. From AVMA Guidelines for the Euthanasia of Animals:2013 Edition.
