How to open the ampoule cap?

Generally, it is an open bottle (that is, a white glass bottle) with a blue dot around the bottleneck. It is much easier to break it along the blue dot with a small grinding wheel the size of a button. If there is no grinding wheel, you can use something else instead. In fact, sometimes we don't row, just break along the blue dot. If you are afraid of scratching your hand, you can wrap it with a cloth to prevent the glass from splashing.

Some bottles have a red dot on them. Hold it with your thumb, the upper part of the bottle with your right hand and the bottle with your left hand. Take the concave bottle force as the starting point, but break it by hand. Don't be afraid. If you are really scared, just wrap it in a piece of paper and break it. At the same time, drugs should be kept in a cool place, out of the reach of children. Dispose of the bottle after use, and don't throw it away at will. Pollution the environment. It should be wrapped in garbage bags and marked with fragile objects on the surface.
