As a consumable used in combination with the pipette, the suction head can be divided into standard suction head, filter cartridge suction head, and low adsorption suction head according to the different applications.

Standard suction heads are the most widely used suction heads, and almost all pipette operations can use ordinary suction heads, which is the most economical class of suction heads.

The filter cartridge suction is a consumable designed to avoid cross contamination and is often used in molecular biology, cytology, virology and other experiments.

For experiments with high sensitivity requirements, or precious samples or reagents that are easy to remain, low adsorption heads can be selected to improve recovery. The surface of the low adsorption head has been treated with hydrophobic treatment, which can reduce the low surface tension liquid left more residue in the head.
