Pipetting is one of the most common tasks in daily laboratory work. Studies have shown that over 40% of laboratory professionals experience physical discomfort from pipetting. In order to obtain the best ergonomic advantage, the following qualities must be observed when choosing a pipette:
1. Small pipetting force, tip installation force and tip ejection force
2. Balanced and comfortable to hold
3. Light weight and suitable length
4. Quick and easy capacity adjustment
5. Easy to read capacity display
6. Can be operated by left and right hands

To avoid aerosol or droplet spreading of the sample when the tip is ejected, one must make sure to choose a pipette with soft tips. If the spray head is soft when it is ejected, the remaining droplets or aerosols are less likely to spread over a large area. If you want a quick and easy decontamination step, choose an entire autoclaved pipette that doesn't require disassembly. This also applies to multi-channel models. You should choose a pipette that can use the filter on the tip cone, or you can use a filter tip.
All pipettes require regular maintenance to ensure reliable results and maximum equipment life. However, in reality, many pipettes "do not work" because the pipette is broken, but the pipette needs maintenance. When choosing a pipette, choose one that is easy to remove, with as few removable parts as possible. The easiest-to-maintain pipettes have only three removable parts that can be removed without tools.
