SomnoSuite® Low-Flow Anesthesia System

Starting at $4,975

SomnoSuite is our innovative low-flow anesthesia delivery system designed specifically for mice and rats. Unlike traditional vaporizers, the SomnoSuite is engineered with a precision syringe pump and integrated digital vaporizer which uses either room air or compressed gas to deliver anesthesia at low flow rates proportionate to the animal's size. Using less anesthesia not only benefits the animal during procedures, but significantly reduces the risk of exposure to lab personnel from waste anesthesia gas.

Features & Benefits

SomnoSuite® Videos

See why the SomnoSuite low-flow anesthesia is safer for you and your animals, offering higher precision over traditional systems.

See a detailed demonstration of how to set up and operate the SomnoSuite low-flow anesthesia system, which provides both automated and manually adjustable options for precise airflow and anesthesia delivery based on animal body weight.

The SomnoSuite smart low-flow anesthesia system can deliver isoflurane using ambient air or compressed oxygen, increasing the flexibility of your setup. See how to set your SomnoSuite to use ambient air or compressed gas.

The SomnoSuite is electronically calibrated, so no annual calibration or re-certification is required. This low-flow electronic vaporizer maintains accurate anesthesia delivery with solid state electronics, hardware, and software, rather than passive vaporization and moving mechanical parts.

Calculation Based on:
  • Flow rate of 0.2 L/min for SomnoSuite & 2 L/min for Traditional
  • Iso Concentration of 2%
  • Annual calibration cost of $200 – $300* for Traditional.
  • Average cost of a typical 250 mL bottle size of Iso is $35:
    Volume x $35 x 4 = $Cost/year
  • Compressed gas fees vary from academia to pharma. Most tanks are rented with fees for tank fill/replacement averaging ~ $1,000/year.
  • Calculations are based upon a specific customer request, and can be adjusted to other specific uses.

With the RoVent Automatic Ventilator add-on module, the vaporized anesthetic is delivered directly to the animal along the inspiratory line coming from the ventilator. This close proximity of the vaporized gas to the animal’s lungs allows you to use far less anesthetic than traditional vaporizers, which require hook-up on the back side of the ventilator.

Uses Less Anesthetic Gas

The SomnoSuite is specifically designed to be used with mice and rats. It is pre-calibrated for use with both isoflurane and sevoflurane. Typical “human-sized” vaporizers on the market today waste more anesthetic gas than you would actually use in a given procedure. Using the SomnoSuite during a typical 30-minute procedure at a gas concentration of 2.5% isoflurane results in using less than .3 mL of isoflurane! It is capable of anesthetizing up to 2 mice simultaneously. The internal pump allows you to use room air or you may hook it directly to a compressed gas source. If you need to anesthetize more than two mice or multiple

Syringe Selection

For optimum precision, response and consistency of anesthetic delivery, we recommend using the 5mL syringe size for mice and the 10mL syringe size for rats. Because mice require very low flow rates for anesthetic maintenance, very little liquid anesthetic is needed. A larger syringe at the same flow rate will cause the syringe driver mechanism to run more slowly, causing pulsatile flow of anesthetic. For example, for a 30g animal with a calculated maintenance flow of 36mL/min set at 1.5% isoflurane, the syringe pump moves approximately 4 pulses per second with a 5mL syringe, and 2 pulses per second with a 10mL syringe. Although the animal’s response time to changes in anesthetic tends to occur over a few minutes, a more pulsatile anesthetic flow rate may in some cases introduce variables related to anesthetic maintenance.

Average 5 stars:
  • What I like about the system is the easy-operation and precise control of the drug amount, and saving reagent.

  • We are enjoying our original SomnoSuite so much that we ordered 2 more. We found they are relatively easy to setup and start.

  • What I like SomnoSuite thing that it is a small and light so that it is easy to move anywhere I want.

  • I love the SomnoSuite system, because it is digital, we have absolute control over the delivered anesthetic, it has an intuitive user interface with an easy-to-use touchscreen, it can be enhanced with other functionalities within the same device (e.g. pulse oximetry, CO2 measurements etc.), it can be used with multiple animals at the same time, and many other functions that analog systems do not offer.

    Our lab uses only SomnoSuite, and I propose the system to other colleagues as well.

  • I love it. It works very easily and I have no trouble at all. I find it simple to use and excellent.

    I think most of the other investigators I have spoken with have also switched to this system.
