Biological culture vessel with light-shielding sheet

Abstract

The invention discloses a biological culture vessel with a light-shielding sheet. The biological culture vessel comprises a nontransparent vessel body and a transparent vessel cover, wherein the vessel cover is composed of a panel and a skirt edge; the skirt edge sleeves the vessel body; a plurality of arc-shaped notches are formed on the skirt edge; blocking slots are formed on the side walls on one side of the notches; a plurality of arc-shaped lug bosses are formed on an outer wall of the vessel body; the lug bosses are inserted into the blocking slots at the skirt edge; an annular groove is formed on a lower end face of the vessel cover on the inner side of the skirt edge; a sealing ring is fixedly clung to the interior of the annular groove; the sealing ring is annularly pressed on an upper end face of the vessel body; an annular lug boss is formed on the upper end face of the vessel cover; a positioning column is formed on the vessel cover at the center of the circle of the annular lug boss; a fan-shaped fixed light-shielding sheet and a plurality of fan-shaped moveable light-shielding sheets are arranged in the annular lug boss of the vessel cover; the fixed light-shielding sheet is fixedly clung to the upper end face of the vessel cover; and the moveable light-shielding sheets are overlapped on the fixed light-shielding sheet and are hinged with the positioning column. The biological culture vessel has an excellent sealing property and is capable of meeting the culturing requirement for the photophilous or photophobic microorganisms.

Description

[0001] Technical field: [0002] The invention relates to the technical field of biological culture equipment, in particular to a biological culture dish with a shading sheet. [0003] Background technique: [0004] A petri dish is a laboratory vessel used for microorganism or cell culture, consisting of a flat disc-shaped bottom and a cover, and is widely used in biological experiments and medical experiments for cultivating bacteria and cells. The materials of existing petri dishes are basically divided into two types: plastic and glass, but generally transparent materials, and some cultured bacteria or microorganisms are light-loving and light-averse, and transparent petri dishes have no effect on light-loving bacteria or microorganisms. However, it has a greater impact on bacteria or microorganisms that are disgusted with light, so corresponding petri dishes are equipped for bacteria or microorganisms that are disgusted with light.
