Pipettes, Fillers & Burettes

Choose a pipette or burette rated for the volumes you actually measure, since using one far outside its range hurts accuracy.

A filler bulb suits simple, occasional transfers, while a mechanical or electronic pipette suits repetitive, high-precision work.

An automatic burette gives more consistent, precise drop control than trying to titrate with a pipette alone.

A worn or cracked bulb or pump seal lets air leak in, throwing off your measured volume without any obvious sign.

No, mouth pipetting is outdated and unsafe. A filler bulb, pump, or mechanical pipette should always be used instead.

If measured volumes start drifting from expected results, or the tool hasn't been checked in several months of regular use, it's worth recalibrating or servicing.

An automatic burette refills from a reservoir and often gives a digital or more precise volume readout, saving time on repetitive titrations.

No, always use a fresh tip between different liquids or samples to avoid contamination and inaccurate results.

This usually means the rubber has perished or there's a crack in the seal, letting air leak in. Replacing the bulb is the simplest fix.
