Stoppers/Droppers

Stoppers and droppers are testing equipment used for purposes such as sealing test tubes and moving liquids. For stoppers, silicone and fluorine resin with excellent heat resistance and chemical resistance, natural rubber, and the like are used. Synthetic rubber has high oil resistance and stainless steel pugs can be attached without directly touching the test tube. Cork borers are used for work to cut holes in rubber or cork stoppers, and some stoppers come fabricated to make cutting holes easier. Many droppers are made of silicone or natural rubber, and they are used attached to transfer pipettes, not individually. They are convenient for taking specific amounts of liquid and dripping small amounts of liquid as well as for transferring chemicals and the like from one container to another. Rubber bulbs have 3 valves, and they are used attached to measuring pipettes or transfer pipettes. Droppers and bulbs need to be selected according to the diameter of the opening of the pipette they are attached to.
