EA-34004C Lab Control Unit 

Four Cage Outputs – 4 Programmable Timing Presets with Individual Start Times

Compliant with AVMA Guidelines

  • Increases efficiency by staggering cage start times
  • Treats animals at individual cage level
  • Designed for investigators that need to retrieve animals quickly
  • Utilizing the full range of Euthanex lids, Sure-Seal Chambers, or existing induction chambers
  • Minimizes operator error and excessive gas use
  • Automatic shut-off saves gas and protects personnel
  • Double throw switches start and stop each output
  • Lights indicate cycle completion
  • Controller easily attaches to wall

The EA-34004C Lab Control Unit automates on/off gas flow at the push of a button, delivering CO2 to individual induction chambers or Euthanex Lids. The EA-34004C is designed for small scale use by individual investigators in their laboratories. The Controller has four separate and independent gas outputs – allowing up to four cages to be euthanized individually or staggered. This feature increases the user efficiency when individually euthanizing a large number of animals. The run and ready lights easily indicate outputs in operation. Operates at a fixed flow rate based on the external CO2 source.

Euthanex recommends pairing Flow Restrictors with our lids or Sure-Seal Chambers for the EA-34004C to avoid the need to adjust the incoming flow rate as the number of cages connected changes. Flow Restrictors are chosen according to your cage size and installed into the Euthanex lid or Sure-Seal Chamber. Using consistent pressure, the AVMA compliant flow rate will be delivered to each cage – regardless of the number of chambers in use.

EA-34004C includes:

SMARTBOX® Lab Control Unit and four color-coded EA-1130 Lab Unit Hoses (Lids sold separately)







Add our E-27000 SMALL MOBILE WORKSTATION and we can mount the EA-34004C to the workstation for a complete mobile solution. Contact Customer Service (1-877-559-0159) for more information.





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-1150-P Preset Regulator – (0 – 50 PSI Output) Connects directly to the CO2 cylinder with CGA-320 fitting. For use with equipment that requires a specific incoming pressure. Preset at factory. Non-heated.

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.
