SomnoSuite Low-Flow Anaesthesia System

SomnoSuite is Kent Scientific’s innovative low-flow anaesthesia 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 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

SomnoSuite Videos

See why the SomnoSuite low-flow anaesthesia system 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 anaesthesia 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 anaesthesia 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.

Extend Your SomnoSuite’s Capabilities with the Following Add-On Modules

Start with the modules you need now and add on later. All modules are sold separately.

• Automatic Ventilator Module – RoVent®

• Pulse Oximeter & Heart Rate Monitor Module – MouseSTAT®

• End-Tidal CO2 Monitor Module – CapnoScan®

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.

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

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 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 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 anesthetize more than two mice or multiple

Syringe Selection

For optimum precision, response and consistency of anaesthetic 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 anaesthetic 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 anaesthetic tends to occur over a few minutes, a more pulsatile anesthetic flow rate may in some cases introduce variables related to anesthetic maintenance.
