There are tubing sets available on the BASi webpage that support operating up to 3 probes in parallel (e.g. OFM-P3-110, Three Channel Push Tubing or OFM-PH3 Three Channel OFM Pump Head Tubing). Please refer to the OFM pump user manual which is also available on the BASi webpage (Resources & Support). Chapter “Installing Pump Tubing and Perfusate Bag” shows step by step instructions on how to install the tubing into the pump head.
