Pipette Use Steps

In the research of analytical testing, a pipette is generally used to measure a small amount or a small amount of liquid. The correct use of the pipette and some details

Operation is something that many people will ignore and is described in detail in several aspects.

Range adjustment
When adjusting the range, if you want to adjust from a large volume to a small volume, follow the normal adjustment method, turn the knob clockwise; but if you want to adjust from a small volume to a large volume,

You can first rotate the scale knob counterclockwise to the scale beyond the range, and then adjust back to the set volume, so as to ensure the highest accuracy of the measurement.
During this process, never push the button out of the range, otherwise it will get stuck in the internal mechanism and damage the pipette.

Assembly of the gun head
When putting a pipette tips on a pipette, many people will knock a few times on the tip of the gun, which is a mistake because it will cause the inside of the pipette.

Parts (such as springs) become loose due to the instantaneous impact force generated by the tap, and may even cause the scale adjustment knob to become stuck. The correct way is to insert the pipette (vertical) vertically

In the tip of the gun, a slight force can be used to make it tightly coupled. If it is a multi-channel (such as 8 or 12) pipette, you can align the first line of the pipette with the first one.

The tip of the gun is then inserted obliquely and can be clamped by shaking in the forward and backward directions. The logo of the gun head is slightly over the O-ring, and the connecting part can be seen to form a clear seal.
