Water, Pure & Simple ..

Complications with drinking water for laboratory rodents, either too much water or no water at all, are among the most common complaints an animal facility manager receives today.  Historically, the only options have been water bottles or automatic watering.   Avidity is now proud to offer a revolutionary alternative.


We are pleased to present an alternative watering system that vastly reduces labor, scientific variables, operating costs and ergonomic issues, while offering improved animal husbandry procedures.

The Hydropac® Pouch and sterile disposable valve™ offers a convenient, reliable and economical alternative watering system for various research rodents.  Designed for use with facility-supplied drinking water, the AWS-2500 Pouch Machine produces up to 600 water pouches an hour by a specially formulated FDA-grade Hydroseal™ film that is fed through the machines to produce hermetically sealed, ready-to-use individual water pouches.  A sterile disposable drinking valve delivers water from a pouch to the research animal.  Valve installation is quick and easy. Just press a valve into the stainless steel grommet, push a filled pouch onto the valve and that’s it – you’re ready to go!
