Description

Technical Field

[0001] The utility model relates to the field of centrifuge tube cover openers, in particular to a multi-purpose centrifuge tube cover opener. Background Art

[0002] Centrifuge tubes are essential consumables in molecular biology experiments. They are primarily used for dispensing reagents or samples. Common laboratory sizes include 0.2ml, 0.5ml, 1.5ml, and 2ml. During experiments, lab technicians frequently open and close the caps of different tube sizes. Currently, most commercially available centrifuge tubes are made of polypropylene (PP) or polyethylene (PE). These tubes have the following drawbacks: First, they can easily injure fingers: The caps are too soft, snap tightly together, and lack a firm pressure point, making them prone to thumb injuries. Second, they can affect work efficiency: opening the caps is laborious, and different cap openers are required for different tube sizes, significantly impacting efficiency. Third, they can easily cross-contaminate different samples: manually opening or closing the caps can easily touch the inner wall of the tube caps, causing cross-contamination between samples and affecting the accuracy of experimental results. Therefore, a convenient cap opener that prevents cross-contamination is needed to address these technical issues. Utility Model Content
