Measuring pipette is the straight glass tube with scale.Designed for quantitatively dispensing exact volumes of liquid. The pipette is usually used when the reaction needs to be controlled of adding liquid. The process of "ring printing" is adopted, which has the characteristics of clear lines, uniform thickness, bright color and no change of color. It not only has beautiful appearance, but also has accurate capacity. Volumes range from 0.1ml to 50ml. A and B grades are available.
Application:
1. Before use
Check whether the upper and tip are damaged or stained.To observe the sizes of the pipettes, the sizes of the pipettes used should be equal to or approximately equal to the volume of the solution to be absorbed.
2. Grip:
The thumb and middle finger clip the pipette, the index finger is free.
3. Absorb:
Vertical liquid intake, moderate depth, Ear Wash ball absorption, liquid extraction height higher than 2-75px scale, index finger according to the upper end of the intake pipette, scale pipette lift off the liquid surface, observe no bubbles in the liquid, filter paper wipe off the wall of the pipe
4 drain liquid to graduation line:
The pipette is vertical, the right eye is parallel to the graduation line, loosen the index finger gently, rotate the pipette, so that the liquid level slowly decreases, only to the lowest point and the graduation line tangentially.
5 Drain liquid to container
The pipette is vertical and the container is inclined 45 degree so that the solution flows out of the container naturally.
A pipette absorbs only one solvent and immerses it in water immediately after use.
Attention:
1 Should not be dried in oven
2. Do not absorb solutions that are too hot or too cold.
3. The same pipette should be used as far as possible in the same experiment.
4. After the pipette is used, it should be washed with tap water and distilled water immediately and placed on the pipette rack.
5. In order to reduce measurement errors when using the pipette, the solution of the required volume should be lowered from the top scale (0 scale) at each time, instead of absorbing as much volume as needed.
