Did you choose the right pipette tip?
Pipette tips are one of the commonly used experimental consumables in the laboratory. They are basically disposable and are used very frequently. For consumables such as suction tips, some experimenters often only seek low prices, but ignore their quality. In fact, the effect of the quality of the tip on the experimental effect cannot be ignored, so what impact will the inferior tip have on the test? How to choose a suitable tip?
The main influences of the tip on the test are as follows:
1. PipetteTips material
Generally, good tips are mostly made of 100% impurity-free polypropylene (PP) material, free of plasticizers, heavy metals and other substances. The endurance endurance in a high temperature environment is also better.
2. The matching of the Filter tips
The matching of the tip and the pipette will directly affect the accuracy of the experimental results. If you choose a poor quality tip, it is easy to have the problem of different tip sizes and poor sealing performance, which will lead to the accuracy of liquid absorption. In addition, when using a discharge gun to pipette, this type of tip is prone to uneven liquid level, which will lead to deviations in experimental data. In the final analysis, it is due to the limited manufacturing process of the tip. Therefore, laboratory personnel must select high-quality tips when choosing products.
3. The structure of the Robotic tips
Because the inner wall of the poor quality tip is rough, has burrs, the tip is even notched, etc., when using a pipette to discharge liquid, there will be residual liquid on the inner wall of the tip and appear to be wall-mounted, especially for refined sample pipetting operations , Trace residues will directly affect the accuracy of experimental data.
