Description

Compliance made easy for CO2 Euthanasia

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 70% Chamber Vol/min
Large Rat Cage
19” x 10” x 8” = 1520 in3.
1520 in3 x 0.70 = 1,064 in3 (flow rate wanted 1,064 in3/min).
1,064 in3/min divided by 61 = 17.4 l/min AIMS CO2 flowmeter setting.

AIMS CO2 Chamber (cylinder)
π x Radius2 x Height
3.14 x 4”2 x 7” = 352 in3.
352 in3 x 0.70 = 246 in3 (flow rate wanted 246 in3/min).
246 in3/min divided by 61 = 4.0 l/min AIMS CO2 flowmeter setting.

Which CO2 Flowmeter to use? Calculate the total volume of your chamber in cubic inches (in3). Your chamber volume should fall between the min and max of the selected CO2 flowmeter for the selected Chamber Displacement Rate (CDR).

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 30% to 70% 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:2020 Edition.
