All you need to know about your 4U Pump

is a 4-channel precision pressure pump for a variety of microfluidic applications, where accurate and stable flow rate delivery is required. All the features of the pump can be controlled with the

: up to 10 bar or 145 PSI - external compressor or vacuum pump required.

Can the 4U Pump be used for Droplet Generation experiments (single and double encapsulation)?

✅ Yes, one of the applications of our 4U Pumps is Droplet Generation. Below is a video on how to use 4U Pump for Droplet Generation:

Can the 4U Pump be used for long term cell culture and Organ-on-chip experiments?

✅ Yes, one of the applications of our 4U Pumps is Organ-on-chip experiments. Below is a video on how to use 4U Pump for Organ-on-chip studies:

Can two 4U Pumps be used simultaneously while using the SmartFlo software?

✅ Currently, the 4U Pump is optimised to be used individually but we would be happy to customise the pump as per your needs and requirements.

Can you use the 4U Pump with your existing flow chambers and tubing kits?

✅ Yes, 4U Pumps are compatible with different flow chambers and tubing. However, if you require tubing and flow chambers, we would be happy to provide them. Check them out on our

✅ Yes, the flow control in the 4U Pump is completely customisable. Below is a video on how to customise flow control:

✅ Please, do not force it. It can damage the pump. You must press on the edge of the fluidic adaptor it is connected to, and then pull it out slowly.

✅ Please, check if all the fluidic connections are tightened properly so they are not leaking air. Ensure you also check connections to the sample reservoirs and flow sensors.

✅ Make sure that the external air compressor is connected and switched on.

✅ Please, press the power button and hold it for 2-3 seconds until it turns green. If you press the button but do not hold it pressed, the pump will not power up. This is the same for powering down the pump.

✅ Make sure that the pressure line hose is 6mm in diameter. If your external pressure compressor has a bigger or smaller pressure line hose, you will need a pneumatic adapter to 6mm. These are widely available.
