Suction head as a consumable used in combination with pipette, generally according to the different applications can be divided into: standard suction head; Filter element suction head; Low adsorption head; No heat source suction first class.

1. Standard type: It is a widely used suction head, and almost all pipette operations can use ordinary suction heads, which is an economical class of suction heads.

2. Filter cartridge type: It is a consumable designed to avoid cross contamination and is often used in molecular biology, cytology, virology and other experiments.

3, low adsorption type: For experiments with high sensitivity requirements, or precious samples or reagents that are easy to remain, you can choose low adsorption type to improve the recovery rate. The surface of the low adsorption type is treated with hydrophobic treatment, which can reduce the low surface tension liquid leaving more residue in the suction head.
