Multichannel Perfusion System
for single ion channel and whole-cell Solution exchange |
 |
MPS-2 is a programmable 8-channel perfusion system designed for single channel and whole-cell patch preparations. It offers the best combination of performance and value. The MPS-2 incorporates the same high quality solenoid valves found on similar but much more expensive systems. Unlike other perfusion systems on the market, which often compromise performance to fit every possible application. The MPS-2 is the only perfusion system designed and optimized specifically for single-channel and whole-cell patch perfusion applications. The MPS-2 is therefore the best perfusion system on the market for these specific applications and is offered at a very attractive price.

The system can be controlled manually (i.e., via membrane switches on the front panel) or through a PC. Two different manual control modes are offered. One controls each channel independently and the other mode allows the user to assign a master channel that will keep the system flow when all other channels are switched off. User-friendly graphic timing software is included, and the programmed perfusion sequence can be started by computer, a patch clamp amplifier or other external trigger, or manually by the user
The perfusion fluid flows through specially designed color-coded polyurethane ribbon style tubing. The color-coding allows the user to easily trace each channel for diagnostic or set up. The ribbon style of the tubing keeps the system very neat and clean. Unlike PVC based tubing, polyurethane tubing contains no plasticizer, which can caused contamination. The tubing ribbon is designed as an economical disposable item, which is often critical when cleanness is needed.
The most unique feature of the MPS-2 is its perfusion mini manifold. Using the latest microfluidic techniques, the injection molded mini manifold provides the least flow resistance and dead volume of any product on the market. The flow channel inner diameter is approximately 1.0 mm, except for the last 5 mm before the junction point. This design allows a fast flow rate without using a pressured system. The maximum flow rates are 1 and 16 microliter per second for the 15 mm long 100 µm and 250 µm ID tips, respectively. Small channels and a unique design at the merging point further reduce the chance of cross contamination. Dead volume is less than 80 nL. The injection-molded mini manifold is also designed as an economical disposable item, eliminating problems of cross-contamination from other experiments.
