Système perfusion gravité VCPlus-4
ALA Scientific’s 4 channel gravity flow perfusion systems fulfill the basic requirements of the student lab and can also be optimized to fit the most demanding applications of patch clamp recording and/or imaging. All VCPlus gravity systems provide electronic control of solution exchange. This improves reproducibility over manual methods. These systems are designed to minimize electronic noise so sensitive electrophysiological recordings can be performed.
Key features of the VCPlus-4 gravity systems include:
Choice of low-maintenance pinch valves or fast response isolation valves
- Customizable reservoir sizes and materials
- Valve control through 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 to indicate valve opening
- Spike and hold circuit for each valve for rapid valve opening and cool valve operation
VCPlus Systems have the option of integrating either pinch or isolation valves. Three-way pinch valves have response times of 15-20ms and are easy to clean because solution runs through the valve in removable tubing. Isolation valves have response times of 2-3ms and are made for high speed applications.
Unlike other competitive perfusion systems, all VCPlus systems include Windows compatible command software. This software allows users to set protocols for opening and closing of specific channels for preset amounts of time. Protocols can be initiated by starting within software or by external trigger from data acquisition systems. Individual valves of the VCPlus systems can also be controlled via analog or TTL input.
