PHM-127
Volumetric Drinking Tubes
for Liquid Intake Monitoring

Quickly and Easily Monitor Liquid Intake ideal for:
• Drug Dosing
• Phenotyping
• General Health Monitoring

Do you need to quantify daily water consumption in your mice but don’t want to invest in expensive equipment? Our PHM-127 Volumetric Drinking Tubes are economical solutions that provide accurate and reliable measurements of water intake. Now you can equip all of your cages with volumetric drinking tubes to monitor water intake in your entire colony, or in just a few cages.

Two sizes available will handle daily water consumption volumes from just a few milliliters up to 50 milliliters. Drinking tubes feature high quality lixit valves to minimize problems associated with leaks.

Two valve styles are available:
• Standard lixit valves when cost is a factor
• Deluxe lixit valves, featuring a Teflon gasket to prevent bedding from jamming the valve

Both valve styles are highly resistant to leak problems and allow for accurate quantitation of daily water intake. Standard valves are easier for the animal to operate, and may be preferable for small mice, or animals that have a weaker lick.

Case Study: Doxycylcine in the Drinking Water A biomedical research laboratory developed a transgenic mouse model that featured a tet-inducible transgene. Expression of the transgene could be down regulated by including doxycycline in the animals’ drinking water. Accurate quantitation of daily water intake was necessary for determining the appropriate oral dosage of doxycycline. Med Associates’ PHM-127 volumetric drinking tube design allowed accurate determination of water intake in mice, resulting in accurate dosing of doxycycline.
