Demonstrating the Precision of Low-Flow Anesthesia Systems Observing the Tail Curl Reaction in an Anesthetized Mouse


  • Everything has been going very well - we have done a ton of surgeries in the last few weeks and used minimal isoflurane with no obvious exposures, which my technician is thrilled with.

  • We have a few somnosuites as well as somnoflos, they are great!

  • Thank you for reaching out. We purchased the SomnoFlo several months ago and absolutely love it! We have used it many times and, while we had issues at the beginning with a calibration issue that Kent Scientific fixed quickly, we haven’t had any issues since and it has worked great! We have been telling other groups here at CSU to purchase one for their labs. Most labs here use the older style vaporizing anesthesia systems that require annual calibration so switching would be advantageous as well as a cheaper alternative

  • We have 4 SomnoFlo units and all 4 of us rodent surgeons here LOVE them! The vaporizers are used extensively and we've had them for almost a year now and not one of us had to replace the 250ml bottle of Isoflurane that we started with yet. It is so efficient that from November until this month (August), and after 166 surgeries, the charcoal filter is heavier by a mere 14 grams. We placed an order for 1 more unit recently so that we can completely replace all of the high flow vaporizers that we used before.

  • We actually did order a SomnoFlo and we like it a lot. We just ordered a second one.
