Quietek CO2 Induction Systems

Overview

Automated Euthanization Device Ensures AVMA Compliance

humane CO2 induction guidelines

Now you can ensure that your laboratory rodents are humanely euthanized without disrupting your laboratory workflow. The Quietek™, in use worldwide since 2013, is the original, affordable, fully-automated instrument specifically designed to ensure compliance with 2013 AVMA guidelines. (It’s also designed to withstand urine and excrement.)

Takes the Guesswork Out of Euthanasia

Designed by animal research facility managers and scientists, easy to use, accurate system ensures that you correctly administer CO2 by automatically calculating gas delivery for your cage volume and desired fill rate. CO2 conditions will be consistent every time, thereby eliminating a source of variation.

Fail-Safe and Easy to Operate

All you need to do is press the start button. There are no valves to turn (or accidentally leave open) between runs and no regulators to adjust. Ideal for the inexperienced, sleep deprived, or overworked laboratory technician. The Quietek also features a key lock that prevents unwanted or accidental tampering with the settings.

Reduces Impact on Your Lab

The Quietek seamlessly integrates into your current protocols. Use it with most common chambers or cages. Lids are available in several sizes.


Benefits

humane CO2 induction in rodent cage

Easy Compliance

The Quietek seamlessly integrates into your existing workflow with no additional training required. Just push the “Start” button to operate.

Prevents Errors

The recommended gas rate is administered appropriately, every time. Use the key lock to prevent settings from being changed.

Consistent

The Quietek eliminates variation in CO2 induction conditions which can change tissue characteristics. A run timer allows you to document conditions for each animal.

Humane

Flow and pressure sensors ensure that the flow of CO2 is accurate, so that ethical standards are maintained. With this precision, you can tailor the flow rate as desired within the guidelines, such as to be more gradual or to save time.

Features

Features

All of our models can switch between 2 cage sizes, for example, if a lab works with mice and rats or 2 different size mouse cages.
The Quietek™ 1 is available with and without RapidFill™, in which after the rodent is anesthetized, you can maximize the fill rate and save time. The Quietek 2 can run CO2 into 2 cages of the same size. A researcher can start CO2 into the first cage, and a few minutes later start CO2 into the second cage. The Quietek XL is for larger cages.

Contact us about custom models.

Quietek models are designed for different sizes and numbers of cages.The Quietek 1 is suitable for cages between 3 and 30 liters in volume, and can be used with one chamber at a time. The Quietek 2 can be used for two chambers simultaneously.For larger chamber sizes (30 to 200 liters), we offer the Quietek XL. If you require an instrument for very small chamber sizes (0.5 to 10 liters), choose the Quietek SC.

Calibration

Calibration & Service

The Quietek™ is a robust instrument. Its precision should not vary significantly over time, however, periodic calibration ensures proper operation such that it meets or exceeds the ethical and quality standards of your animal use program. The Quietek is not serviceable by anyone other than Next Advance certified technicians. The software is integrally coupled to the hardware. Modification of any components may render the instrument inaccurate and will void any warranty.

Next Advance continuously strives to provide industry leading solutions to researchers in the life sciences. We regularly identify and make modifications to our products to improve functionality and operation. The Quietek calibration service will provide you with the latest software update, will include repair and replacement of worn parts (misuse or abuse is not covered), and will submit your Quietek to our vigorous testing procedure, thereby ensuring that the Quietek is fully compliant when it leaves our facility.

Any custom program requirements you wish to have can likely be included as well. If you have custom flow requirements we can incorporate those as part of this service.

Note that for calibration or any other service, you must clean your Quietek and certify that it has been decontaminated. Please contact us before shipping the Quietek.


Guidelines By Country

International Guidelines

Now you can ensure that your laboratory rodents are humanely euthanized without disrupting your laboratory workflow. Introducing the Quietek™, the affordable, fully-automated device specifically designed by us to ensure compliance with strict international guidelines.

United States: “An optimal flow rate for CO2 euthanasia systems should displace 10% to 30% of the chamber or cage volume/min. Prefilled chambers are unacceptable.” 2013 AVMA Guidelines (pg. 49)

Canada: “…a gradual-fill rate of less than 30% and greater than 20% of the chamber volume per minute should be used.” CCAC Guidelines on: Euthanasia of Animals Used in Science (pg. 19)

United Kingdom: “Exposure to carbon dioxide gas in a rising concentration: appropriate for rodents and rabbits and birds up to 1.5kg…a controllable, metered source of carbon dioxide gas should be used.” The Humane Killing of Animals under Schedule 1 to the Animals (Scientific Procedures) Act 1986 (pg. 6)

European Union: “Only to be used in gradual fill.” Official Journal of the European Union (pg. 72, 73)

Australia: “a gradual fill of the chamber with 100% CO2 at a rate to fill 20% of the chamber volume per minute was agreed as good practice” Guidelines to Promote the Well-being of Animals Used for Scientific Purposes (pg. H3)
