Pipettes

Calibration frequency depends on usage intensity and method risk. Many labs verify pipettes quarterly for critical work and at longer intervals for routine applications.

Multichannel models are useful when the workflow repeatedly loads plates, strips, or parallel rows. Single-channel pipettes are more flexible for mixed-volume or low-throughput tasks.

Choose a volume range that keeps routine transfers near the middle of the instrument range, where control and repeatability are usually easier to maintain.

Accuracy describes how close a dispensed volume is to the target value, while precision describes how consistently repeated transfers match one another.

Not always. Electronic pipettes help with repeat dispensing and operator fatigue, while manual pipettes are often preferred for simpler workflows, lower cost, and easier field replacement.
