Mounting of Perfusion Capillary:
The system has to be absolutely free of air bubbles to allow backlash-free pumping. The back of the perfusion capillary must be made burr-free by fire-polishing to prevent scratching of Teflon sealing cone and silicone tubing. Also, avoid scratches on the pump piston and on the sealing surface of the compression screw.
Remove Teflon cone only with supplied special tool. For instructions on how to open the pump, mail us.
Keep ambient temperature constant as thermal expansion or shrinkage of capillary and pump piston may lead to significant errors in the perfusion rate. At end of the experiment, release pressure on silicone tubing and Teflon cone by loosening front end cap and compression screw and remove perfusion capillary.
