Sealed reaction bottle for adding reactant step by step

Abstract

The invention provides a sealed reaction bottle structure for adding reactant step by step. The sealed reaction bottle structure comprises a bottle cap, a bottle body, a small beaker, a connection rod, rotating shafts, sealing rings and a drain valve. The upper portion of a reaction bottle is provided with the bottle cap. The bottle cap and a bottle body opening are tightly connected in a ground mode through grinding sand, and the airtightness of the reaction is guaranteed. The two ends of a beaker opening of the small beaker are fixedly connected with the connection rod, so that the beaker opening of the empty small beaker can face upwards. The connection rod is fixedly connected with the rotating shafts through clamping grooves. The center of the bottle wall is provided with two opposite small holes, the two rotating shafts penetrate through the two small holes respectively, and the overturning angle of the small beaker is adjusted by controlling the rotating shafts. The connection positions of the small holes and the rotating shafts are sealed through the two sealing rings. The bottom of the bottle body is provided with the drain valve, and reaction waste liquid is drained out of the reaction bottle through the drain valve. According to the sealed reaction bottle structure for adding reactant step by step, poisonous and harmful gas substances generated in the reactant mixing process are limited in a closed space, and the health of a human body is protected; the feeding time and speed of reaction liquid in the small beaker are adjusted by controlling the small beaker, a reaction is controlled, and the sealed reaction bottle structure is more reasonable in structural design.

Description

technical field [0001] The invention relates to a sealed reaction bottle for adding reactants step by step, belonging to the field of biological or chemical experiment consumables. Background technique [0002] Many biological and chemical experimental reactions require successive addition of two reactants, some of which are volatile, irritating and toxic. In addition, the two reactants may also produce toxic and harmful substances during the reaction process, which will cause harm to human health. For example, when two reactants, hydrochloric acid (HCl) and sodium hypochlorite (NaClO), are mixed, a redox reaction occurs to produce chlorine gas (Cl 2 ), and chlorine gas is a poisonous gas with a very strong pungent odor, which can invade the human body through the respiratory tract, cause damage to the upper respiratory tract mucosa, and cause breathing difficulties. When performing this type of reaction, it must be operated in a fume hood, and the toxic gas produced is re...

Problems solved by technology

However, in some cases, no fume hood is available, and the toxic gases produced by the reaction can easily affect human health if they are directly discharged into the air
