“We use the ValveBank in electrophysiology on a Xenopus oocyte recording rig. We have run a twelve-channel manual perfusion delivery system for several years with timed solenoid valves. The ValveBank and accompanying EasyCode Macintosh software allow us to program full wash and delivery sequences in advance with significantly more accurate switching. The new manual perfusion timing option allowed the ValveBank to perform exactly like the controller we had built before. Basically, the ValveBank saves us the worries of monitoring reagentdelivery, and it works.” Dr. David Julius Department of Cellular and Molecular Pharmacology University of California, San Francisco­­ ValveBank® Controller • Run experiments automatically – even unattended By running experiments automatically, AutoMate Scientific systems will leave you free to accomplish other tasks – saving you both time and money. • Microprocessor-based for accuracy and flexibility The ValveBank® can store sixteen user programs with 10 millisecond switching accuracy. It includes powerful perfusion commands and capabilities not offered by competing valve drivers: open single or multiple valves, master channel for control/buffer solution, and computer control. • Low noise & low voltage valve control Designed for electrophysiology. CE marked for Europe. • Manual, TTL (digital), and serial (RS-232) inputs Control valves manually (by keypad) or by computer – simultaneously thanks to the microprocessor design. • Low cost & low profile, simple design ­ Optional BNC cables and 19” rack-mounting brackets.

VALVEBANK CONTROLLER • User-selectable for normally open or closed valves • 1.5 amp, 12V AC power supply included All AutoMate Scientific valve controllers switch 12V DC solenoid valves open and closed rapidly using full power, then hold-in at 1/2 power to prevent thermal transfer to your solutions. Low noise circuitry minimizes recording artifacts in electrophysiology. ValveBanks are designed for use with pClamp, Pulse, et al. All AutoMate Scientific products include a one-year warranty. The ValveBank® remains the only programmable valve controller for physiology that does not require a computer....
