Pipette suction head, also called TIP head, pipette nozzle.

The pipette suction is an indispensable tool in the experimenter's hand. A suitable pipette nozzle can not only reduce the loss of pipette, but also improve the accuracy of experimental results. The suction head is a disposable consumable, which can be directly in contact with the liquid sample. It will not only affect the accuracy of the pipetting results, but also affect the analysis results directly if it is dissolved or contains foreign biological pollutants.

So, how should the experimenter choose the right suction head? From the following aspects:

1. Low adsorption

When a low adsorption suction head removes a liquid with low surface tension, the liquid can slide off the inner surface of the suction head very easily, leaving very little residual liquid in the suction head. This low adsorption property is useful for PCR, real-time PCR, cloning, SDS-PAGE, and other nucleic acid or protein analysis methods.

2. With filter element

a. Anti-contamination. The filter element is a consumable designed to avoid cross contamination and is often used in molecular biology, cytology, virology and other experiments. Helps to reduce the likelihood of smoke formation and prevent aero
