Categories: ,

Details

Each VCPlus-8xG Series system includes the following:

  • Magnetic stand with 2 x 18” poles
  • Valve manifold with isolation or pinch valves
  • Reservoir bracket with 60 mL syringe reservoirs
  • VCPlus electronic valve controller with a USB-C cable and control software
  • DB9-CABLE controller to valve manifold cable
  • Manual 3-way stop cock Luer valves and tubing
  • MMF-8 MiniManifold™ or MLF-8 MilliManifold™

Additional options include:

  • Spill sensor: used to detect spills around the microscope to prevent damage to expensive optics
  • Flow Control Valve, FCV-1: manual pinch valve with thumb screw to adjust output flow rates from the output of the MMF-8 or MLF-8
  • 5ml or 10ml syringe reservoirs
  • Breakout Box: BOB-8 for TTL trigger inputs

Valves

Each VCPlus-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.
  • 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 2 – 3 ms.

ABOUT

ALA Scientific’s 4 and 8 channel gravity flow perfusion systems are ideal for student labs and advanced applications like patch clamp recording and imaging. They feature electronic control of solution exchange, enhancing reproducibility and minimizing electronic noise for sensitive electrophysiological recordings.

 

Key features of the VCPlus-8 gravity systems include:

  • Choice of low-maintenance pinch valves or fast response isolation valves
  • Customizable reservoir sizes and materials
  • Valve control via DAQ, VCPlus software, or controller
  • Optional spill sensor with automatic shutoff to protect microscope optics
  • MilliManifold™ and MicroManifold™ outlet options for low volume and rapid applications
  • TTL timestamp for valve operation tracking
  • Spike and hold circuit for rapid and cool valve operation

VCPlus Systems offer pinch valves with 15 – 20 ms response times and easy cleaning, and isolation valves with 2 – 3 ms response times for high-speed applications. Unlike competitors, all VCPlus systems include Windows-compatible software for setting and initiating protocols, with control options via analog or TTL input.
