Can pipette tips be reused?

Pipette tips are disposable plastic tips used in laboratories and clinical diagnostics, primarily for accurate and precise dispensing of liquids. They are designed for single use to ensure the stability of metrological properties and to avoid contamination.

Pipette tips can be used to measure liquids multiple times, but they must not be reused once they are ejected from the pipette. To achieve a leak-free seal with the pipette, the tip material is slightly elastic. Repeated installation of the tip may result in reduced accuracy and precision. However, some special material pipette tips, such as PFA material pipette tips, can be reused and can withstand a variety of strong acids and alkalis. In addition, autoclavable pipette tips are also suitable for repeated sterile use.
