Pipettes are often used to remove a small amount of liquid in the laboratory. Micropipette first appeared in 1956, invented by Schnitger who is a scientist of the Institute of physiology and chemistry, Germany.
Pipettes of different specifications are equipped with different sizes of pipette tips. Shapes of different manufacturers are slightly different, but the working principle and operation method are basically the same.
Pipettes are a kind of precision instrument, when use and storage, should be careful to prevent damage and avoid affecting its range.
Adjustment of pipette range
When adjusting the range, if you want to adjust from large volume to small volume, according to the normal adjustment method, clockwise rotation knob. But if you want to adjust from small volume to large volume, you can first turn the scale knob counterclockwise to the scale beyond the range, and then adjust back to the set volume, which can ensure the highest accuracy of the measurement. In this process, do not turn the button out of the range, otherwise, it will jam the internal mechanical device and damage the pipette.
After use, pipettes can be hung vertically on the pipette holder, but be careful not to fall off.
