Reagent bottle

The sealing of the bottle mouth and cap is good, without the need for a cork, and it is also non permeable; the wide mouth design is convenient to use, with a smooth inner and outer wall, easy to clean, and there is no liquid residue on the inner wall of the bottle mouth, which can be cleaned in boiling nitric acid. All other concentrated, dilute, inorganic, (acid, alkali, ester) are ineffective. It is suitable for placing, high-purity, strong corrosive drugs, chemical reagents, and standard samples. However, it may be difficult to remove the cork due to long-term non use. The reason is that the liquid reagent evaporates and adheres to the glass between the cork. In this case,..." Take the following method:

1. Drop a small amount of water at the mouth of the bottle, hold the bottle body and the cork with both hands, and shake them evenly left and right to remove the cork.

2. Place the reagent bottle flat facing down into a beaker filled with hot water, soak for about 5 minutes, and wait for small bubbles to appear at the bottle mouth. Take out the bottle and hold it tightly with one hand, while shaking the cork with the other hand to remove it. If it still cannot be removed, continue soaking until it can be removed
