Product Innovation

We are dedicated to the advancement of science by developing groundbreaking products designed to maximize productivity and generate accurate and reliable research data, which ultimately propels important research discoveries. Our commitment to product innovation recently led us to the development of the UID Mouse Matrix, a home cage activity and temperature monitoring system for rodents, and the UID Controlled Substance Inventory System, an RFID system for secure and accurate management of controlled substances.

UID Mouse Matrix

Home cage activity and temperature monitoring system for rodents

  • Continuous, real time (24/7) recording of animal location, movement and temperature.
  • Undisturbed, remote monitoring of Group Housed animal activity.
  • Individual monitoring of up to 5 mice per cage.
  • Objective monitoring of animal behavior at night when the lights are off and rodents are most active.
  • Create your own Smart Cage for rodent activity monitoring.

Controlled Substance Inventory System

RFID system for secure and accurate management of controlled substances

  • Combines a two-part authentication process, novel software and RFID tracking technology for secure access and detailed inventory for controlled substances.
  • Accurate account for the use and storage of controlled substances.
  • Reduce errors and miscalculations inherent in manual data entry systems.
  • All records captured electronically for accurate inventory and documentation.

Customer Testimonials

“The temp microchips were a godsend! The entire staff was incredibly happy – much faster to collect the temps and MUCH less messy! 😉 It was so quick and easy getting the temps, that we were able to collect them 3x/day from 50 lambs and thus catch animals sooner when they were getting ill. Plus we were able to provide additional data for the researchers, which they appreciated. All around this change was a raving success!”

“The UID microchips and reader are wonderful, practical, simple, and very easy to use. We tested it on mice that we analyzed for 30 days. After that time, the reader correctly read all the animals. We are very happy with the purchase and very grateful for this recommendation.”

The temperature monitoring system “…is working excellent. We were surprised how close we had to hold it to the animal [pigs] and it has to be held what we consider upside down. However, it is ten thousand times better than taking rectal temps!”
