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!”

“My company has migrated to almost exclusive use of RFID for identification. This facilitates workflows and electronic data collections and reduced the human error in maintaining and reading other forms of identification. We exclusively use rodent models. The platform we use is from UID Identification Solutions for both rats and mice. The chips are proprietary to the UID readers but they have a whole series from handheld, to wands, and pass throughs. The chips are very reasonable in price and come with the advantage of user defined character space on the chip identification. This was very attractive to us as we can put our animal numbers and study numbers on the chip in human readable form rather than relying on a computer to read the chip code (very hard for staff to use that number to drive operations). In addition, we have now been using their temperature capable chips that will simultaneously provide body temperature at the same time as the animal ID, very useful for our host resistance studies. We are also using the 2D arrays from that are the footprint of rodent cages and facilitate tracking animal activity and body temperature in real-time. We are very pleased with the product and will continue to use UID. In addition, their customer service and troubleshooting is very good, responsive, and timely.”

“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!”

“We use the Unified Information Devices (UID) equipment at our facility, we have been using it for about 3 years now. All of their equipment is durable and on the rare occasion we need something repaired they have never charged us for it! Their micro-chips are programable but don’t have to be as each chip has a unique number/letter combination already on that can be used for identification. As far as I know this system is compatible with most any data collection programs being used. UID has everything you need for animal identification, TA jar identification, micro-chip implantation, etc. They will also work with you on quantity pricing for micro-chips and other items. UIDs customer service is second to none. If I have a problem I call (they will answer) or e-mail them and they are always happy to help. I have zero complaints with UID.”

“I did our pilot study with just the microchips and I came in 2x/day to take temps. It was nice that the reader worked through the cage, so I didn’t have to open each cage twice a day.”

“We have been using the temperature microchips in a few pigs now and they work well. Anecdotally, the microchip and rectal temperatures are the same. I am happy with the option overall.”

“As someone who used to (and still does when helping with other people’s projects) use a rectal probe for temperature monitoring, these chips are an amazing time saver, way more accurate and help keep my mice straightened out over the prolonged period I have them. I thoroughly enjoy using them. I would hate to go back to a rectal probe!”
