A pipette tip is one of the commonly used experimental consumables in the laboratory. They are disposable and used frequently. For consumables such as tips, many experimenters often only pursue cheapness, but ignore their quality. In fact, the influence of the quality of the pipette tips on the experimental results should not be underestimated. What impact will the pipette tip with poor quality have on the experiment? How to choose the right pipette tip?
The influence of the pipette tip on the experiment mainly includes the following points:
1. The material of the pipette tip
Generally, the best pipette tip is mostly made from 100% impurity-free polypropylene, free of plasticizers, heavy metals and other substances, and the wall of the pipette tip has good elasticity. Such tips can be used in low temperatures or high temperatures. The endurance tolerance is also good.
2. The matching of the pipette tip
The matching of the pipette tip and the pipette will directly affect the accuracy of the experimental results. The manufacturing process of inferior pipette tips can easily lead to problems such as different sizes and poor sealing of pipette tips, which will affect the accuracy of liquid suction. When pipetting with a discharge gun, such tips are prone to uneven liquid levels, which may lead to deviations in experimental data.
3. The structure of the pipette tip
There are burrs and the tip even lacks material for the pipette tip due to the rough inner wall. When the pipette is used for the discharging liquid, there will be residual liquid on the inner wall of the pipette tip, which will hang on the wall. Residues may directly affect the accuracy of experimental data, especially in fine sample pipetting.
4. The purchase of pipette tips
The pipette tip with better material, smooth inner wall and fine processing should be selected as far as possible, and the matching of the pipette should be taken into consideration to ensure the accuracy of the experiment.
