"As long as it can be mounted on the suction head is a usable suction head" -- this is almost all users of the common understanding of the suitability of the suction head. This is partly true but not entirely true. The pipette can be mounted on the suction head and pipette can indeed form a pipette system to achieve the pipette function, but is this reliable? A question mark needs to be placed here. The answer to that question requires data.

1, you may wish to match the pipette with the suction head after the performance test. After washing the suction head, repeat the sample adding operation several times, weigh each sample adding amount, and record the reading.

2, according to the density of the test liquid converted into volume and then calculate the accuracy and accuracy of pipette operation.

3, we want to choose a suction head with good accuracy. If the pipette and the pipette are not matched accurately, the seal between the pipette and the pipette is not guaranteed, making the result of each operation impossible to reproduce.
