1. Standard suction head

The standard suction head (that is, the ordinary suction head) is a widely used suction head, and it is the most affordable class of suction heads, and other types of suction heads are also evolved from the standard suction head. If there are no special requirements, most pipetting needs can be met by using standard suction heads.

2. Low adsorption head

The surface of the low adsorption head has been treated with hydrophobic treatment, which can reduce the surface tension of the liquid left more residue in the head.

In general, when the liquid is discharged, a part of it will remain in the inside of the suction head, no matter what experiment is done, it will cause a certain result error.

3. Filter element suction head

Filter element suction head is a suction head designed to avoid cross contamination. The sample removed by the filter cartridge suction head will not enter the inside of the pipette, thus protecting the pipette components from contamination and corrosion, and more importantly, ensuring that there is no cross-contamination between the samples.
