AMPLIFIED ANIMAL RESEARCH

The new UTAS with BigShot™ offers researchers the most capable animal ganzfeld on the market. Perform flash ERG (with option to add pattern testing) with ease on any small-to-medium sized animal. Adding to its flexibility, BigShot can also be used for human clinical research as well as veterinary clinic use.

With over 40 years of electrophysiology experience, amplification with LKC’s digital biomedical amplifiers allows faithful reproduction of every nuanced recording.

Upgrades & New Features

 

The UTAS now has a reduced footprint and features three noticeable upgrades in its hardware and functionality

Pattern-Based Test Monitor:  The CRT pattern monitor has been replaced with a high-quality LCD Monitor carefully selected and driven in a manner to clinically eliminate customary flash artifacts common to LCD displays and to maintain the superior performance formally only found in CRTs


 

New UTAS Interface: The MGIT or Isolation Transformer and the UTAS Interface were combined into one unit and will now take only half the space


UBA Biomedical Amplifier

Completely redesigned UBA amplifier offering six differential channels with 24 bit A-to-D conversion using a native USB connection.

The previous UBA had an amplifier unit attached to the UBA interface unit via a fiber-optic cable, which was then connected to the computer through a separate USB cable.


Windows 10 Compatibility

The enhanced UTAS system is now fully Windows 10 based allowing the UTAS to benefit from the latest PC technology and associated security enhancements

Testimonials

“I have been a loyal LKC customer for over 20 years. I started with the UTAS system for ERG testing to determine not just surgery candidacy for patients with cataracts, but also to thoroughly evaluate retinal function in cases with retinopathy and vision loss.”
