Glass Pasteur Pipette With Cotton

Pasteur pipette is a glass tube with opening at both ends. One end of the pipette is narrow and the external diameter is 1 mm , and the external diameter of the other end is 7.2mm equipped with a rubber dropper.Excellent visibility. It has a wide range of applications and can be used in biology, bacteriology, hematology and other laboratories.

Generally, it is used to transfer and disperse a small amount of liquid safety and rapidly , but it can be "corrected" by counting the number of droplets transferred by milliliters. Before use, cotton plug is inserted into the upper end of the pipette, and then sterilized. The pipette is blocked by this method. The liquid transferred from the pipette can avoid microbial contamination. In microbiology, the pipette should be blocked with cotton plugs for the same reason. The groove at the upper end can prevent the cotton from sliding into the pipe.

 Red latex dropper bulb optional.
