Overview

The VC3-8xP Series from ALA includes 8 channel valve controlled pressurized perfusion systems that fulfill the basic requirements of the student lab but can also be optimized to fit the most demanding applications of patch clamp recording and/or imaging. All VC3-8xP Series systems provide electronic control of solution exchange which improves reproducibility over manual methods. These systems are designed to minimize electronic noise so sensitive electrophysiological recordings are not disturbed.

Key features of the VC3-8xP Series include:

  • Choice of low-maintenance pinch valves or fast-response isolation
    valves
  • Customizable reservoir sizes and materials
  • DAQ control via analog or TTL input
  • Valve control through DAQ, Valve Commander software, or controller
  • Optional spill sensor with automatic shutoff to protect microscope
    optics
  • Optional MilliManifold™  or Quartz MicroManifold®  perfusion outlet options for low volume and rapid solution exchange applications
  • Valve open and close timestamps via analog or digital output

Details

Each VC3-8xP Series system includes the following:

  • Magnetic stand with 1 x pole
  • Valve manifold with isolation or pinch valves and 5mL pressurized
    syringe reservoirs
  • VC3 electronic valve controller with a USB cable and Valve
    Commander software
  • DB9-CABLE controller to valve manifold cable

Each VC3-8xP 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.
  • Isolation valves: These 2-way normally closed isolation valves
    are optimized for high-speed solution exchange. These valves are
    completely isolated when closed and have response times of 3 to 4
    ms.

Additional options include:

  • Glass reservoirs for volatile solutions
  • Spill sensor: used to detect spills around the microscope to prevent damage to expensive optics
  • Breakout Box: BOB-8 for TTL trigger inputs or outputs

Need to be ordered separately:

  • 8 x CF-1’s and QMM-4WT for fast focal applications
  • MLF-8 and tubing for fast bath applications
