Precautions for Using Beaker Tongs

Beaker tongs are used to clamp and move high-temperature objects in chemical experiments, especially crucibles, evaporating dishes, etc. The precautions for use mainly include the following points:

1. Clamping method: When using beaker tongs, clamp from the bottom or side of the object to ensure that the clamp is stable and avoid slipping or falling.

2. Heating and cooling: Beaker tongs can be used directly to clamp heated objects, but sudden cooling should be avoided during the clamping process to prevent the object from bursting. If the clamped object needs to be cooled, it should be placed in a suitable place such as an asbestos net or a dryer for slow cooling.

3. Operation safety: When using beaker tongs, wear experimental protective equipment such as gloves and protective glasses. Avoid direct contact with the clamping part of the beaker tongs with your hands to prevent burns. During operation, stay away from flammable items to prevent high-temperature objects from causing fires.

4. Maintenance and care: After use, the beaker tongs should be cleaned in time to avoid residual substances affecting its service life and performance. Regularly check whether the clamping part of the beaker tongs is intact. If damaged, it should be replaced in time.

5. Other precautions: Do not use beaker tongs to hold objects that are too heavy or too large to avoid exceeding their carrying capacity. Avoid using beaker tongs to hold fragile or easily deformed objects to prevent damage.
