Do mechanical pipetting devices eliminate all hazards associated with pipetting?

Mechanical pipetting devices do not eliminate all hazards associated with pipetting, which is why the correct answer is that it is false. While these devices can significantly reduce risks associated with manual pipetting, such as exposure to contaminants and repetitive strain injuries, they do not entirely remove all potential hazards.

For instance, while a mechanical pipette can prevent direct contact with hazardous liquids, it does not eliminate the risk of spills or aerosols that could occur when handling the samples or during the pipetting process itself. Additionally, users may still face ergonomic risks if they do not maintain proper posture or technique, regardless of the device used. Mechanical pipetting devices also require proper maintenance and calibration; failure to uphold these practices might lead to malfunctioning equipment, which can cause additional hazards.

By understanding that mechanical pipetting devices improve safety but do not guarantee complete elimination of hazards, users can maintain a higher level of vigilance and employ additional safety measures in the laboratory environment.
