Installation: The correct installation method is called rotating installation method, the specific practice is to insert the top of the white sleeve into the suction head (whether it is the bulk suction head or the box suction head is the same), while gently pressing down, the pipette in the handle is rotated 180 degrees counterclockwise. Remember that the force should not be too strong, not to take the method of cutting the head to install, because doing so will cause unnecessary damage to the pipette in your hand.

Capacity setting: The correct capacity setting is divided into two steps, one is rough adjustment, that is, through the emission button to quickly adjust the capacity value close to their own expected value; The second is fine adjustment, when the capacity value is close to its expected value, the pipette should be placed horizontally in front of its own eyes, and the capacity value will be slowly adjusted to the expected value through the adjustment wheel, so as to avoid the impact caused by visual errors. When setting the capacity, there is another area that needs special attention. When we go from a large value to a small value, it's just fine; However, when the small value is adjusted to the large value, it needs to be adjusted more than a third of the circle and then returned, because there is a certain gap in the counter that needs to be made up.
