Mechanical pipetting devices eliminate all hazards associated with pipetting.

Mechanical pipetting devices are designed to reduce some of the hazards associated with manual pipetting, such as exposure to potentially hazardous biological agents or chemical spills. However, they do not eliminate all hazards entirely. For instance, while these devices can minimize the risk of aspiration and exposure to toxic substances, they may not safeguard against all forms of contamination—particularly if proper technique is not followed. Furthermore, there are still risks related to the handling of samples, potential mechanical failure, and misuse of the devices. Hence, it is important to practice good laboratory techniques and follow safety protocols regardless of the equipment being used. This understanding is crucial for maintaining a safe laboratory environment.
