R540 Enhanced Anesthesia Machine


The Enhanced animal veterinary anesthesia machine is designed for safe, simple, and controllable inhalation anesthesia for rat, mouse, rabbit, hamster and Guinea pig, with two anesthetic agents optional.


The R540 incorporates the following functions in addition to the functions of the preceding R510 tabletop anesthesia machine:

The push button O2 Quick Flush purges induction chamber at the rate of at least 1000 cc/min before removing animals, or rescuing animals during your experiment.

The Toggle Switch allows convenient and fast switch of gas flow between induction chamber and anesthesia masks (breathers).

Table top and wall mount available in one unit, and post mount optional.



  • Design generous, beautiful appearance, simple operation
  • Accurate oxygen flow meter, Flow control range: 0-4 L/min available
  • High accuracy vaporizer (Each one has an independent test report)
  • Gas toggle switch, button switching gas path, more than 100,000 times of service life.
  • Quick oxygenation switch to remove residual anesthetic mixture in the tube or anesthesia induction chamber.
  • Oxygen or air can be chosen as gas supply.
  • Easy Fill, Pour Fill, Key Fill for adding drugs is optional.
  • Can be upgraded into portable anesthesia machine to save space and facilitate movement
  • The double flowmeters installation space on the back to meet the simultaneous

About RWD Anesthesia

RWD Life Science has been always dedicated to study and provide perfect and competitive inhalation anesthesia systems that have great practical value to the life science research community. Multiple complete solutions to different procedures in mice, rats, rabbits, cats, dogs, monkey, pig etc. have been set up, which has remarkable and even exclusive advantages over existing system, for example:

  1. Precise and stable control of anesthetic agents output regardless of environmental changes like pressure, temperature and air flow within the specific limits.
  2. The miniaturized design like anesthesia machines and scavenging system helps to improve laboratory space utilization.
  3. Unique stereotaxic frame nosecone masks and cone masks with tiny sizes satisfy more delicate surgeries like craniocerebral and ophthalmological surgery, and at the same time minimize harmful exposure to the research subjects while connecting to evacuation system.
  4. The latest-designed waste gas evacuation system with weighing (Cat No.R546W) brings research subjects great convenience.
  5. Higher performance to price ratio helps research subjects to reduce their expense while maintaining successful research.
  6. High adsorption efficiency of activated charcoal filter canister (Cat No.R510-31 & R510-31S).

Advantages of Inhalation Anesthesia:

  1. Can offer an improved level of control over depth and duration of anesthesia, especially for prolonged procedures.
  2. To be relatively insoluble and faster elimination in blood enables rapid recovery.
  3. Be of rapid onset and offset with minimal side effects.
  4. Have little or no toxic effects thanks to non-metabolism characteristic of Sevoflurane and Isoflurane.
  5. Be more safer and efficient performance to reduce morbidity rates and increase the chance for successful outcomes.
