MPS-2 Multichannel Perfusion System for single ion channel and whole-cell solution exchange ● Manual or Programmable PC control with user-friendly GUI interface ● Fast LAFF solenoid valve ● Color-coded polyurethane tubing for easy identification ● Super low dead volume (<100 nL) micromanifold ● Economically priced inputs from 1/16” ID tubing internal passage ID: 250 µm PUMPS, MICROINJECTION mounting rod connector output: 100 or 250 µm ID quartz/ polymide tubing 14 mm OD internal junction OD: 600 µm Micromanifold closeup: Fluid-filled passages are shown in magenta. MPS-2 is a programmable 8-channel perfusion system designed for single channel and whole-cell patch preparations. Offering 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 system can be controlled manually 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 MPS-2 Multichannel Perfusion System & Control Software allows the user to easily trace each channel for REPLACEMENT PARTS diagnostic checks or set up and the ribbon style of 502109-15 Color-coded Polyurethane Tubing, 1/16” ID x 8 Channels, 15 ft tubing keeps the system very neat and organized. Unlike 502110 Micromanifold, 100 µm ID tip, 2 pcs/pk PVC based tubing, polyurethane tubing contains no 502125 Micromanifold, 200 µm ID tip, 2 pcs/pk plasticizer, which can cause contamination. The tubing ribbon is designed as an economical disposable item, Specify line voltage and Micromanifold tip OD when ordering. which is often critical when cleanness is needed. MPS-2 SPECIFICATIONS CHANNELS VALVE RESPONSE TIME VALVE CONTROL SYRINGE RESERVOIR VOLUME MANIFOLD TIP ID MAXIMUM FLOW RATES (gravity fed) DEAD VOLUME 8 2 ms USB, TTL, external start via software 10 mL 8 to 1 250 micron and 100 micron. 100 µm ID tip, 8 µL/min. at 50 cm 250 µm ID tip, 250-500 µL/min. at 50 cm < 100 nL excluding the single outlet tubing The most unique feature of the MPS-2 is its perfusion micromanifold. Using the latest microfluidic techniques, the injection molded micromanifold 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 50 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 100 nL.
