Neck and back problems, pain in the hand and fatigue. That's the other side of lab life. Excessive effort, high operating forces and repeated physical strain can cause health problems in the long run. This is not only inconvenient for people in the lab, but also for their employers. Syndromes like the repetitive strain injury syndrome (RSI) increase the number of absences from work.
Today, healthy working conditions become more and more important. Responsible organizations already discover the value of personal health for their company culture, being a prerequisite for long term competitive advantage.
Ergonomics means to never feel the effects of hard work!
Ergonomic working conditions start with the pipette itself: the shape, the weight, operating forces, the concept of operation. Even small differences between the pipettes used on a daily basis can make the difference between development or absence of health problems:
- Operational forces play a crucial role during the pipetting action. For example, repetitive and effortful pressing of the control and eject button under permanent change of thumb position puts stress on your muscles of hand and fingers.
- The volume adjustment of a mechanical pipette with gloves requires manual dexterity. The repeated thumb movements require relatively strong muscle activity.
- A pipette with an unfavorable center of gravity can be poorly balanced in the hand. This requires a stronger grip, which in turn places unnecessary strain on the hand and fingers.
