The pipette tip, just like the bullet of the gun, is an indispensable accessory. In theory, the quality of the tip also has a great influence on the accuracy of pipetting, and its importance is no less than that of the pipette itself.[ Micro Filter Tips,Filter Tips 200ul,Pipette Tip 200ul,Blue Pipette Tips,300 Blue Pipette Tips ]
The current pipette tips on the market are basically made of polypropylene plastic (colorless and transparent plastic with high chemical inertness and a wide temperature range). However, the same polypropylene has a big quality difference: high-quality tips are generally made of natural polypropylene, while cheap tips are likely to use recycled polypropylene plastic (in this case , We can only say that its main ingredient is polypropylene).[ Micro Filter Tips,Filter Tips 200ul,Pipette Tip 200ul,Blue Pipette Tips,300 Blue Pipette Tips ]
In addition, most of the tips will add a small amount of additives during the manufacturing process. The more common additives are:
1. Chromogenic materials. The commonly known blue nozzles (1000ul) and yellow nozzles (200ul) on the market are the addition of corresponding color-developing materials to polypropylene (as a user, you definitely want high-quality masterbatches instead of low-cost industrial pigments. );
2. Release agent. It is mainly used to help the suction head to be separated from the mold quickly after forming. In this case, the more additives, the higher the probability that an undesirable chemical reaction may occur during the pipetting process. So the safest thing is to add no additives.
However, due to the relatively high production process requirements, pipette tips without additives are really rare in the market. Therefore, our users can only choose pipette tips with less additives when choosing.
