The peristaltic tubing sizes are rather arbitrary and are labeled by numbers: 13, 14, 16, 17, and 18 in increasing order of size.
The table below gives you an idea of the flow rates that can be achieved by a peristaltic pump for different tubing sizes.
For 100 rpm pumps
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 |
For 600 rpm pumps
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) | ~6-100 | ~6-100 | ~6-100 | ~6-100 | ~6-100 |
Flow Rate (mL/min) | 0.36-36.0 | 1.3-130.0 | 4.8-480 | 17-1700 | 23-2300 |
