The utility model relates to a culture dish with a movable inner bottom. The existing petri dishes can generally achieve good airtightness, but when the air pressure in the bottle changes, it is often not easy to find or observe, which is unfavorable for the culture process. The composition of the present utility model includes: a petri dish body, the bottle bottom of the body has a small hole (1) and an annular protrusion (2), the bottle mouth of the body is provided with a sealing gasket, the body and the The lid is connected with a sealing gasket. The inner wall of the main body is coated with lubricating oil that does not affect the growth of the culture. The inner bottom that moves freely along the inner wall is installed inside the main body. The side wall of the inner bottom is in the shape of an inner The concave arc is connected with the body bottle body in point contact. The utility model is used for plant tissue culture.
Description
技术领域：Technical field:
本实用新型涉及一种带可移动内底的培养皿。The utility model relates to a culture dish with a movable inner bottom.
背景技术：Background technique:
培养皿是一种用于微生物或细胞培养的实验室器皿，由一个平面圆盘状的底和一个盖组成，一般用玻璃或塑料制成。培养皿材质基本上分为两类，主要为塑料和玻璃的，玻璃的可以用于植物材料、微生物培养和动物细胞的贴壁培养也可能用到。塑料的可能是聚乙烯材料的，有一次性的和多次使用的，适合实验室接种、划线、分离细菌的操作，可以用于植物材料的培养。现有的培养皿一般都能做到具有良好的密封性，但当瓶内的气压有变化时，往往不能轻易发现或观察到，这对于培养过程是不利的。A petri dish is a laboratory vessel used for microbial or cell culture, consisting of a flat disc-shaped bottom and a cover, generally made of glass or plastic. The materials of petri dishes are basically divided into two categories, mainly plastic and glass. Glass can be used for plant materials, microbial culture and animal cell adherent culture. The plastic ones may be made of polyethylene materials, and there are disposable and multiple-use ones, which are suitable for laboratory inoculation, streaking, and isolation of bacteria, and can be used for the cultivation of plant materials. The existing petri dishes can generally achieve good airtightness, but when the air pressure in the bottle changes, it is often not easy to find or observe, which is unfavorable for the culture process.
实用新型内容：Utility model content:
本实用新型的目的是提供一种带可移动内底的培养皿。The purpose of the utility model is to provide a petri dish with a movable inner bottom.
上述的目的通过以下的技术方案实现：Above-mentioned purpose realizes by following technical scheme:
一种带可移动内底的培养皿，其组成包括: 培养皿本体，所述的本体的瓶底具有小孔和环形凸起，所述的本体的瓶口处设置有密封垫，所述的本体与带密封垫的皿盖连接，所述的本体的内壁涂有不影响培养物生长的润滑油，所述的本体内安装有沿内壁自由移动的內底，所述的內底的侧壁呈内凹弧形，与所述的本体瓶身点接触连接。A petri dish with a removable inner bottom, which consists of: a petri dish body, the bottom of the body has a small hole and an annular protrusion, the mouth of the body is provided with a gasket, the The main body is connected with the dish cover with a sealing gasket, the inner wall of the main body is coated with lubricating oil that does not affect the growth of the culture, the inner bottom that moves freely along the inner wall is installed in the main body, and the side wall of the inner bottom is It is in a concave arc shape, and is in point contact with the body bottle body.
有益效果：Beneficial effect:
本实用新型的内底的侧壁是内凹弧形，与瓶身成点接触连接，这样的结构使得内底与瓶身的接触面积小，从而在润滑油的作用下内底可沿着瓶身上下移动。由于内底通过瓶底的小孔受外界大气压作用，培养过程产生气体或消耗气体导致的瓶内气压变化会使内底上下移动，这样就能在实验过程中直观地看到瓶内气压变化。本实用新型结构简单。The side wall of the inner bottom of the utility model is concave arc-shaped, and is connected with the bottle body in point contact. Such a structure makes the contact area between the inner bottom and the bottle body small, so that the inner bottom can move along the bottle Move up and down. Since the inner bottom is affected by the external atmospheric pressure through the small hole in the bottom of the bottle, the inner bottom will move up and down due to the change of the inner bottom pressure caused by the gas production or gas consumption during the cultivation process, so that the change of the inner pressure of the bottle can be seen intuitively during the experiment. The utility model is simple in structure.
