Does your pump integrate push and pull options in the same unit? Is there any calibration required?
Yes, the OFM pump (MPP102PC) has push and pull options in the same unit. Either one pump head can be used for push and the second pump head for pull or, wit...

How tightly controlled are the push and pull pump heads? Is there any difference between the push and pull pump head settings (for example, pull setting is 10% higher than the push)?
Flow rates can be adjusted between 0.1–10 µl/min with an accuracy of ± 20%. We recommend using pre-calibrated tubing to ensure sufficient accuracy.  Furtherm...

What is the flow rate range with which I can operate the OFM pump in push-pull mode?
Lowest flow rate: 0.1 µl/min Highest flow rate: 10 µl/min. Flow rates can be adjusted between 0.1 – 10 µl/min with an accuracy of ± 20%. We recommend us...

Do I have to use the OFM Bag to deliver the perfusate (e.g., aCSF) or can I use a container filled with the buffer externally?
For better sampling results, we recommend using the OFM perfusate bag, which is delivered fully sealed in gamma irradiated protective packaging. However, if...

Is there any potential for CPU control of the OFM pump in the future?
Joanneum Reaserach is considering a CPU control for the next version but unfortunately it is not yet available for the current version.

How do you prevent liquid from coming out of the connectors on the perfusate bag when filling with a syringe?
Please refer to the OFM pump user manual which is also available on the BASi webpage (Resources & Support). Chapter “Installing Pump Tubing and Perfusat...

How do you fit up to 3 tubings at one pump head?
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...

What is second flush mode? Is this necessary when running on one flow rate?
Flush mode is generally used to flush the tubing set and get rid of air bubbles. Thus the pump is operated at a freely selectable flowrate of e.g. 10 µl/min...

Why would we need to have different flow rate settings for P1 and P2?
cOFM probes are normally used at the same flow rate for P1 and P2 (e.g. 0.3 to 1 µl/min), but as the pump is also designed to operate dermal probes, flow ra...
