Tubing Number | 13 | 14 | 16 | 17 | 18 |
|---|---|---|---|---|---|
Tubing Size(ID) | 0.8 mm | 1.6 mm | 3 mm | 6.3 mm | 8 mm |
Pump Speed (rpm) | ~2-100 | ~2-100 | ~2-100 | ~2-100 | ~2-100 |
Flow Rate (mL/min) | 0.1-6.0 | 0.3-21.0 | 1.3-80.0 | 4-280 | 6-380 |
From this chart, you can easily calculate a pump speed given a tubing number and flowrate. At the appropriate tubing number, divide the given flowrate by the maximum flowrate and multiple this quantity by 100. This simple calculation will give you the speed of the pump in rpms given a tubing size and flow rate.
