Description

Technical Field

[0001] The utility model relates to the technical field of pipette tip detection, in particular to a detection device for pipette tips. Background Technique

[0002] Pipette tips are tools for liquid transfer in laboratories. They are usually made of plastic, and there are tips with different capacities and shapes suitable for different operation requirements. Pipette tips are connected to a pipettor through a pipette or an electronic pipette, and are used to accurately aspirate and release liquids. For example, they are commonly used to dispense solutions, samples or reagents in fields such as molecular biology, biochemistry, and clinical diagnosis.

[0003] Pipette tips play a crucial role in laboratory pipetting operations. If their specifications are incorrect, or there are defects such as leakage holes or surface burrs, it may seriously affect the accuracy and repeatability of experimental results. At present, many manufacturers will conduct manual inspections one by one before leaving the factory to ensure that the quality of the tips meets the standards. However, the one-by-one inspection has low detection efficiency, and even under such strict inspections, due to careless operation or improper protection, there is still a risk of contamination of the pipette tips, and bacteria or other contaminants may adhere to their surfaces.
