Warner Instruments has introduced the VT-8 Valve Timer, a low-cost, easy-to-use eight channel microcontroller-based unit that communicates with Windows-based computers via the high speed USB 2.0 port
Designed with Warner's perfusion valve controllers in mind, the instrument also makes an excellent general purpose lab timer.
A user friendly, software-driven computer interface makes it easy to generate an automated protocol for valve opening and closing during any experiment.
The timer continuously communicates with the computer facilitating instantaneous responses to user-directed commands of the output TTL.
The VT-8 features a 'syringe configuration tool' that ensures adequate solution volume to complete the experiment, and includes an emergency cut-off that can be used to automatically close all valves simultaneously.
