Problems solved by technology
[0002] A beaker is a commonly used vessel in the laboratory, usually made of glass, plastic, or heat-resistant glass. There is a gap at the top to facilitate the pouring of liquid, but the gap on the upper edge of the traditional beaker is not at the same level as the upper edge of the beaker. On the plane, when some volatile liquids are contained in it, the lid is often not tight; and the traditional beaker does not have a handle, which is inconvenient to lift; in addition, the beaker is often used for heating reactions, but the bottom of the beaker is flat. The heating speed will be slower, and the flat bottom is not convenient for some chemical reactions

Embodiment Construction
[0007] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0008] see figure 1 , a beaker, comprising a beaker body 1, the upper edge of the gap 2 on the upper edge of the beaker body 1 is on the same plane as the upper edge of the beaker body 1, which is mainly convenient for other flat-bottomed covers such as glass sheets to be covered on it to prevent For the volatilization of some chemical liquids, a handle 3 is provided on the outer wall of the beaker body 1 opposite to the notch 2. The bottom of the beaker body 1 is an inwardly concave arc-shaped bottom surface 4, and its concavity is preferably 8°. The beaker body 1 can also set the corresponding range scale.

The invention discloses a beaker, relates to an apparatus for a chemical experiment, and aims to provide a beaker which can be tightly covered and is convenient to hold and heat. The beaker comprises a beaker body; the upper edge of a notch on the upper edge of the beaker body is in the same plane with the upper edge of the beaker body; a handle is arranged on an outer wall of one side, opposite to the notch, of the beaker body; and the bottom of the beaker body is an inward-sinking arc bottom surface. Compared with the prior art, the beaker disclosed by the invention has the following advantages: (1) as the upper edge of the notch on the beaker body is in the same plane with the upper edge of the beaker body, the beaker can be tightly covered conveniently with sheet glass and the like so as to avoid loss caused when a volatile substance is contained in the beaker; (2) the beaker is more convenient to hold due to the handle; and (3) the heating area can be increased by the arc bottom surface so as to facilitate quick heating and prevent liquid splash in certain chemical reactions.
Description
technical field [0001] The invention relates to a chemical experiment appliance, in particular to a beaker. Background technique [0002] A beaker is a commonly used vessel in the laboratory, usually made of glass, plastic, or heat-resistant glass. There is a gap at the top to facilitate the pouring of liquid, but the gap on the upper edge of the traditional beaker is not at the same level as the upper edge of the beaker. On the plane, when some volatile liquids are contained in it, the lid is often not tight; and the traditional beaker does not have a handle, which is inconvenient to lift; in addition, the beaker is often used for heating reactions, but the bottom of the beaker is flat. The heating rate will be slower, and the flat bottom is not convenient for some chemical reactions. Contents of the invention [0003] Aiming at the above-mentioned prior art, the technical problem to be solved by the present invention is to provide a beaker with a tight cover, which is c...
