Suction head as a consumable used with pipette, generally according to the different application can be divided into: ①. Standard suction head, ②. Filter element suction head, ③. Low adsorption suction head, ④. No heat source suction.

1, the standard suction head is the use of more suction head, almost all pipetting operation can use ordinary suction head, which is a kind of affordable suction head.

2. Filter element suction is a consumable designed to avoid cross contamination and is often used in molecular biology, cytology, virology and other experiments.

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