LAS VEGAS, September 30, 2014 – Sable Systems International announces the launch of the best-in-class Promethion AC-2 metabolic screening access control module for computer-controlled, automated access to food in mouse and rat laboratory environments. The Promethion AC-2 module retains all the benefits of the earlier model AC-1 module – such as compatibility with numerous feeding programs (paired, yoked, duration-limited and quantity-limited), intelligent obstruction detection, and an entirely in-cage design – while making a number of significant improvements. Most notably, the new AC-2 has stand-alone capability to permit operation without a mass measuring device. This provides better cost-effectiveness for behavioral researchers interested in food access and food choice applications where mass monitoring may not be necessary.

The new AC-2 modules quieter operation decreases animal stress while creating a more pleasant work environment. The AC-2 is more easily mounted to the cage lid with two thumb screws, a setup that requires no tools for mounting. Self-calibration is now easier and more consistent, and a controllable RGB LED light has been added for applications involving operant conditioning or in-cage artificial lighting.

“The AC-2 is, at heart, a result of customer feedback and we’re extremely grateful for all the valuable conversations our customers have had with us,” said Robbin Turner, CEO of Sable Systems International. “It provides a number of improvements over the AC-1 which were requested by customers while further setting the Promethion Access Control module, and the Promethion line as a whole, apart from its competition.”

The Promethion AC-2 metabolic screening access control module is available immediately from Sable Systems. For more information, click here.
