SomnoSuite is the innovative low-flow anesthesia delivery system from Kent Scientific 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 anaesthesia at low flow rates proportionate to the animal’s size. Using less anaesthesia not only benefits the animal during procedures, but significantly reduces the risk of exposure to lab personnel from waste anaesthesia gas.

Features & Benefits

Integrated Digital Vaporizer Auto calculates flow rate based on animal weight
Built-In Air Compressor Uses room air or compressed gas
Flow Rates from 25 mL to 1 L Saves money by using less than 1mL of isoflurane/hour with typical use
Intuitive Touch Screen Control The easy to use multi-parameter touch screen display shows vital signs
Safer for the Animal Digital dial control for precise delivery and safety
Safer for the Technician With such a small amount of anaesthetic and oxygen used there is very little waste gas exposure risk
Induction Chamber Flush Minimizes waste anaesthetic gas exposure
No Servicing or Calibration Needed Cost-effective, reliable equipment
Easily Integrates into Stereotaxic Setups Use your own anaesthesia mask or use one of ours
Modular Capability Select modules for a variety of functions
Smaller Footprint Significantly smaller footprint compared to traditional vaporizer and stand, further reduced by combining additional modules including RoVent and MouseSTAT
Multi-Animal Capability Greater efficiency – Our clinical department will be pleased to review your study protocol to confirm that our product will meet your specific study requirements
Real-Time Recordings
5 Safety Alarms

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.

Uses Less Anaesthetic 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 anaesthetic 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 anaesthetizing 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 anaesthetize more than two mice or multiple rats, check out our traditional multi-animal systems, capable of anaesthetizing up to 6 animals.

SomnoSuite system layout

With the RoVent Automatic Ventilator add-on module, the vaporized anaesthetic 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 anaesthetic than traditional vaporizers, which require hook-up on the back side of the ventilator.

Variety of nosecone sizes
Rodent facemasks and nosecones are available for all systems in many sizes
