Summary datasheet
| Models and ranges | P10 (0.5-10 µL), P20 (2-20 µL), P50 (5-50 µL), P100 (10-100 µL), P200 (20-200 µL), P1000 (100-1000 µL), P5000 (1-5 mL), and P10000 (2-10 mL) |
| Setting increment | 0.1 µL on the P10 up to 0.1 mL on the P10000 |
| Stated systematic error | At nominal volume, from 0.50% on the P5000 to ±0.90% on the P10. The catalog states it at three volumes per model —nominal, half and a third, lower point: one tenth, except on the P5000 and the P10000, where it is the floor of the range—; the worst figure in the whole table is ±2.00% |
| Stated random error | At nominal volume, from ±0.15% on the P100, P200 and P5000 to ±0.80% on the P10. At the other two volumes tabulated, the worst figure in the whole table is ±2.00%, on the P50 at 5 µL |
| Tips | 10, 200, 1000, 5000 µL, and 10 mL depending on the model |
| Sterilization | Fully autoclavable at 121 °C, according to the manufacturer's catalog |
| Availability | Import to order / to be confirmed |
Whole into the autoclave, at 121 °C
That is the statement that defines the family, and the only sterilization claim on the series' page: “Whole Autoclavable — 121 ℃”. There is nothing to disassemble and no parts to protect: the complete instrument goes through the cycle.
The eight published models cover 0.5 µL to 10 mL, with the same tip pattern as the M series —10 µL at the bottom, 200 µL through the middle, own tip on the three largest— and the same increments.
Against the M series it buys autoclavability, not accuracy
At nominal volume the two series state the same figures from 50 µL up. Where the P states less error is in the smaller models and at the low point: the P20 marks ±2% at 2 µL where the M20 marks ±3%, and the P10 states less accuracy error than the M10 at all three volumes in its table, although on repeatability it ties with it at two of them.
Choosing between them comes down to one question: does the instrument have to go into the autoclave? If the answer is no, the M does the same measuring job.
What to look at when picking the step
The rule is the same as for any micropipette —the model's maximum close to your everyday volume— and the P's table shows it just like the M's: ±0.8% at 20 µL against ±2% at 2 µL on the same instrument.
