Pump Speed and Sample Uptake Calculator

Step 1. Select pump configuration

Pump diameter (to outside of rollers)    mm
Number of rollers    
Roller diameter    mm

Step 2. Select pump tubing

Step 3. Calculate pump speed or sample uptake

Sample uptake (µl/min)   Pump speed RPM

Enter your required sample uptake to calculate the pump speed OR your actual pump speed to calculate the sample uptake.

This calculation should be used as a guide only. Variations between pump tubes and roller pressures mean that the accuracy of the calculation cannot be guaranteed.
