Gravity Bath Perfusion  Detailed description

Key features of the VC3-8xG Series include:

Choice of low-maintenance pinch valves or fast-response solenoid valves

Customizable reservoir sizes and materials

DAQ control via analog or TTL input

Valve control through DAQ, Valve Commander software, or controller

Spill sensor with automatic shutoff to protect microscope optics

Valve open and close timestamps via analog or digital output


Each VC3-8xG Series system includes the following:

  • Magnetic stand with poles
  • Valve manifold with solenoid or pinch valves
  • Reservoir bracket with 60mL syringe reservoirs
  • VC3 electronic valve controller with a USB cable and Valve Commander software
  • DB9-BNC8 cable for TTL trigger inputs or outputs
  • DB9-CABLE controller to valve manifold cable
  • Manual 3-way stop cock luer valves, manual pinch flow valves, spill sensor, tubing
  • MMF-8 MiniManifold TM 8 channel perfusion outlet manifold


Each VC3-8xG Series system features a choice of valves:

  • Pinch valves : The 3-way normally open and normally closed pinch valves require minimal maintenance in long-term perfusion experiments and have response times of 15-20 ms.
  • Solenoid valves : The 2-way normally closed solenoid valves are optimized for high-speed solution exchange. These valves feature a biologically inert internally wettable surface and have response times of 1-2 ms.
