ValveBank®4 L/L PTFE inert Perfusion System

Increase reproducibility with 10 millisecond accuracy

Stand-alone design - no computer necessary

Run experiments automatically - even unattended

Microprocessor-based for accuracy and flexibility
Because they lack a microprocessor, competing valve controllers do not offer a serial port, or simultaneous manual and computer valve control.

Manual, TTL (digital input) and RS-232 inputs

*10 millisecond (0.01 sec) switching accuracy
*16 user programs of 256 commands per channel - up to 99 hours long
*Non-volatile battery memory program storage
*Menu-driven interface
*Detached 16-key membrane keypad and 2 line, backlit LCD screen
*Four programmable digital inputs and outputs
*Dual RS-232 serial port
*Many manual perfusion features built-in

Valve Driving:
*Control 4x 12V DC solenoid valves
*User selected normally open or closed
*Valves are opened or closed rapidly using full power, then held-in
at 1/2 power to prevent thermal transfer to your solutions
*Low noise circuitry for electrophysiology

System Includes:
* ValveBank4® controller
* 4x ringstand-mounted 12V DC, two-way solenoid PTFE inert valves
Each valve includes an indicator LED & 5' long RCA cables
* 4-into-1 PTFE inert micro manifold -for bath and Oocyte perfusion
* 4x 35ml syringes and 2-way stopcocks
5, 15, 35, 60 and 140ml syringes available.
* Tubing for plumbing the system
* Power supply and manual
* One year limited warranty covering both parts and labor
