Classification
Divide fat belly pipette and commonly used pipette. It consists of a rubber nipple and a glass tube with a pointed mouth.

Use
Extract or add a small amount of reagent and extract supernatant to separate the precipitate.

Matters needing attention
During drip-adding, the pipette should be kept perpendicular to the top of the container, avoid tilting, do not stand on its head, do not reach into the container, do not touch the container wall. In addition to absorbing the solution, the piping tip should not touch other utensils to avoid contamination of impurities. Do not use one tube for two purposes.

The ordinary pipette needs to be cleaned after use, while the special pipette can not be cleaned, it needs to be dedicated to the tube, put back to the original reagent bottle after use. When using, do not use the only thumb and index finger pinch, with middle finger and ring finger clip.

Method of use
1. When using the eyedropper, squeeze the rubber nipple with your finger to expel the air from the eyedropper, then put the eyedropper into the reagent bottle, release your finger, the reagent will be inhaled.
2. The rubber head should be kept on the upper part of the dropper after taking the liquid, and should not be laid flat or inverted to prevent the reverse flow of the solution from corroding the rubber head.
3. Drop the liquid, it should be suspended on the top of the beaker, do not touch the burning glass wall, so as to avoid contamination of the dropper or reagent pollution.
