The Operation Steps Of Pipette – Assembly Of Pipette Tip
When the pipette tips are put on the pipette, many people will knock hard on the pipette box. This is wrong because it will cause the internal parts of the pipette tips to become loose due to the instantaneous impact force produced by the tapping, and even cause the scale adjustment knob to jam.
The correct method is to insert the liquid transfer device vertically into the pipette tip and to tightly integrate it by slightly turning left and right. The tightening mark of the pipette tip is slightly over the O-ring, and a clear sealing ring can be seen in the connecting part.
The above-mentioned operation method can be simply summarized as the following three steps:
1. Single-channel suction tube, the end of the suction tube is inserted into the suction head vertically, , slightly rotated left and right, and tightened.
2. Do not repeatedly hit the pipette tighten the pipette head, so as not to control the dial knob stuck.
3. Multichannel pipette, the pipette of the first channel is aligned with the first pipette, inserted at an Angle, and gently shaken before and after tightening. When the pipette is inserted, it can be slightly larger than the o-ring.
