EA-34000 Lab Control Unit

Four Cage Output – Four Programmable Timing Presets

Compliant with AVMA Guidelines

  • Treats animals at individual cage level
  • Designed for investigators that need to retrieve animals quickly
  • Utilizing the full range of Euthanex Lids or induction chambers
  • Minimizes operator error and excessive gas use
  • Automatic shut-off saves gas and protects personnel
  • Selector switch allows for four different cycle times
  • Lights indicate cycle completion
  • Easily attaches to wall

The EA-34000 Lab Control Unit is designed for small scale use by individual investigators in their laboratories. The Controller automates on/off gas flow at the push of a button, delivering CO2 to an individual cage or Euthanex lid. The EA-34000 has four gas outputs and four programmable cycles that include charge and dwell times. The run and ready lights visually indicate operation and completion. Operates at a fixed flow rate based on the external CO2 source.

Euthanex recommends paring Flow Restrictors with Lids for the EA-34000 to avoid the need to adjust the incoming flow rate as the number of cages connnected changes. Flow Restrictors are chosen according to your cage size and installed into the Euthanex lid. When a consistent pressure is maintained, the AVMA compliant flow rate will be delivered to each lid -regardless of the number of cages in use.

EA-34000 includes:
SMARTBOX® Lab Control Unit and four EA-1130 Lab Unit Hoses (Lids sold separately)


These products may be required for use with your SMARTBOX Controllers



EA-550 Regulator – (0 – 100 PSI Output) – EA-550 Connects directly to the CO2 cylinder with CGA-320 fitting.  Capable of handling high flow rates. Incorporated electric heater keeps unit from freezing during operation.

EP-IL60 Inline CO2 Regulator  ( 0 – 60 PSI Output) – For use with house gas supply – not for use with cylinders.




Euthanex Lids allow for the treatment of animals in their home cages and are available in a range of sizes.


Flow Restrictors avoid the need to adjust the flow rate due to change in cage number and ensures AVMA compliance of CO2 flow using a set pressure.
