Accuracy and precision are critical performance specifications for Universal Pipettes, ensuring reliable and reproducible liquid transfers. Accuracy refers to how close the pipette volume readings are to the actual volume delivered, while precision refers to the consistency of volume measurements.

Pipettes have varying accuracy and precision specifications, typically represented as a percentage or as deviations in microliters. For example, a pipette with an accuracy of ±0.5% and precision of ±0.2% means that the delivered volume can deviate from the target volume by a maximum of 0.5% and 0.2%, respectively.

Higher-quality pipettes, often with tighter manufacturing tolerances, offer improved accuracy and precision. These are typically recommended for applications where precise measurements are crucial, such as molecular biology experiments, PCR, or any assay where small variations can significantly affect results.

Ergonomics is an important consideration in pipette design, as it directly affects user comfort, ease of operation, and productivity. Pipettes with ergonomic features minimize user fatigue and the risk of repetitive strain injuries during prolonged pipetting sessions.

Ergonomic design elements may include features such as a lightweight and well-balanced body, a comfortable grip, and an easy-to-use plunger mechanism. Some pipettes also offer adjustable finger rests or volume setting dials to accommodate different hand sizes and reduce strain.
