The invention provides a self-sealing reagent cup, relating to a reagent cup. A rubber seal ring (11) is arranged at the upper part in a reagent cup (10) and packages the outer edge of a glass plate (8), two lower ends of an inverse U-shaped rod (13) are fixed on the glass plate, the lower end of a vertical rod (14) is fixed at the upper part of one side of the inverse U-shaped rod, one end of a pressure rod (1) is connected with one end of the vertical rod through a shaft B (15), the other end of the pressure rod is connected with the upper end of a connecting rod (6) through a shaft A (2), the middle of the connecting rod penetrates into a horizontal rod (5) arranged on the other side of the inverse U-shaped rod, the upper and lower ends of a spring (3) sleeving the connecting rod respectively prop against the opposite surfaces of the horizontal rod and the pressure rod, and a cone-shaped sealing pillar (7) arranged at the lower end of the connecting rod penetrates into a taper hole (17) of the glass plate. According to the self-sealing reagent cup, the cone-shaped sealing pillar is opened or closed by virtue of a control part arranged on the glass plate, so that harmful gas produced due to contact between a chemical reagent and air is effectively prevented.
Description
【Technical field】 [0001] The invention relates to a reagent cup, in particular to a self-sealing reagent cup. 【Background technique】 [0002] It is known that chemical reagents are relative standard substances for chemical research and component analysis, and are an important condition for scientific and technological progress. Chemical reagents are widely used in the synthesis, separation, qualitative and quantitative analysis of substances. It can be said that chemical work The eyes of the patient are inseparable from chemical reagents in the daily work of factories, schools, hospitals and research institutes; when chemical reagents are used, some will volatilize when they meet the air, some chemical reagents will deteriorate when they meet the air, and some will When the medium content reaches a certain value, "high concentration" can cause mild irritation of the eyes and respiratory mucosa, anesthesia, and even loss of consciousness. Chronic effects are mild irritation ...
