SomnoSuite® Low-Flow Anesthesia System
"The SomnoSuite is everything it claims to be and more: it uses a fraction of the isoflurane, and as such, minimizes exposure to investigators, all while maintaining perfectly stable levels of anesthesia in our adult rats. The only thing better than having one SomnoSuite would be having two!"

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 rats, click here to check out our traditional multi-animal systems, capable of anesthetizing up to 6 animals.
With the RoVent Automatic Ventilator 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.
Safer for the Animal and Technician
Dialing in the percent of anesthetic gas delivered to the animal is digitally controlled for exact precision and safety. Because you are using such a small amount of anesthetic and oxygen, there is very little waste gas exposure and less risk to you and your environment. A charcoal canister is included with all systems and easily attaches to the back of the SomnoSuite. A charcoal canister will last about 6-weeks (8 hours use per day).
Although supplemental oxygen is appropriate for some studies, prolonged exposure to high oxygen concentrations can create the potential of causing lung injury. Diminished lung volumes, hypoxemia and damge to airways are common results of oxygen overexposure. Designed with an internal pump and a solid state digital vaporizer, the SomnoSuite can run on room air and produces undetectable amounts of waste anesthesia gas (WAG), significantly reducing the risk of oxygen toxicity and WAG exposure.
Using Lower Flow Rates
• leads to significant cost savings: less isoflurane, fewer charcoal canisters.1,2,4
• decreases the risk of personnel WAG exposure.1,4
• benefits the animal's health - high flow rates promote hypothermia and respiratory tract drying.1,4
• improves physiological monitoring accuracy; high fresh gas flows can cause false low ETCO2

Because SomnoSuite requires such small amounts of anesthetic gas and can use room air instead of compressed gas to deliver precise flow rates, your cost savings could be significant. The chart below illustrates particular examples of actual savings from the SomnoSuite's minimal isoflurane use vs. a traditional vaporizer that requires compressed gas at high flow rates.
The SomnoSuite has a significantly smaller footprint on the lab bench compared to the traditional vaporizer and stand. It is extremely portable, similar in size to a laptop computer. The internal pump and optional battery which allows mobility make it possible to use room air to mix with your anesthetic. The RoVent Automatic Ventilator and MouseSTAT Pulse Oximeter are additional modules that can be integrated into the vaporizer unit, further reducing your overall footprint.
Optional induction chambers and nose cones available for purchase (see our selection below).
Kent Scientific recommends the smallest syringe size that will accommodate the duration of your application. Using a large syringe size with very low flow rates can cause uneven anesthetic delivery.

If you are using the SomnoSuite with a compressed oxygen gas source, the pressure from the gas source should be regulated to between 5 and 10psi. An optional pressure reducer is available for purchase if your oxygen source cannot be regulated down to between 5 and 10psi. Click here to view our pressure reducer.

"For anesthesia delivery, precision vaporizers and monitoring equipment (e.g., pulse oximeter for determining arterial blood oxygen saturation levels) increase the safety and choices of anesthetic agents for use in rodents and other small species."
Principles and Guidelines for Reporting Preclinical Research
The NRC held a workshop in June 2014 on the issue of reproducibility and rigor of research findings. The workshop focused on the common opportunities in the scientific publishing arena to enhance rigor and further support research that is reproducible, robust, and transparent.
Physiological monitoring and precision anesthetic delivery help control variables in order to achieve greater reproducibility.
