Micropipette volume ranges
Laboratories usually stock a small set of air-displacement bodies whose nominal ranges overlap common P20 / P200 / P1000 work. Exact min/max is printed on the pipette; this page does not invent a calibration table.
How to read a range
The useful range is the interval printed on the pipette, not a nickname. “P20” in lab speech usually means a micropipette whose upper mark is 20 µL, but always confirm the scale on the instrument and in the SOP.
How labs typically cover a bench
- Low-volume body for single-digit and low-teen microlitres
- Mid-volume body around the 20–200 µL band
- High-volume body around the 100–1000 µL band
Overlap is normal. Do not run a pipette at the extreme bottom of its scale when a smaller body exists — precision usually degrades there. For a buying list, send the volumes you actually pipette, not a brand slogan.
Tips must match the body
A P1000 tip on a P20 body is not a workaround. Specify tip length/filter needs with the volume range in the RFQ.

FAQ
On the calibration certificate and in ISO 8655 for the pipette’s nominal volume. This page does not reprint a guessed table.
Usually no. Cover the bench with a small overlapping set and calibrate that set.
