Culture dish

Abstract

The invention relates to a culture dish. The culture dish comprises a culture dish body. The culture dish body comprises a bottom wall and a lateral wall extending along the periphery of the bottom wall. The bottom wall and the lateral wall form an upper opened space, which is suitable for accommodating a culture. The culture dish also comprises a culture dish cover. The culture dish cover comprises a top wall and a lateral extending along the periphery of the top wall. The culture dish cover can cover the upper opened space from a position above the culture dish body. A first locking part is formed on the lateral wall of the culture dish cover. A second locking part is formed on the lateral wall of the culture dish body. When the first locking part and the second locking part are locked by each other, the culture dish cover is opened in a specific angle relative to the culture dish body. The provided culture dish has the advantages that the culture dish can be placed on a workbench during the process of long term operation in an open state, the operation stability is improved, the size of the opening of the culture dish cover is guaranteed, at the same time, the left hand of a user is freed, and the user can use his left hand and right hand to carry out pipetting or other operations.

Description

technical field [0001] The invention relates to the technical field of cell or microorganism culture; in particular, the invention relates to a petri dish which is easy to operate. Background technique [0002] As containers for culture media, petri dishes have been used for decades in the field of cell or microbial culture technology and are often used in laboratories. Petri dishes are usually round and consist of a body containing the medium and a matching lid. The dish cover is placed on the dish body, which can prevent the medium from being polluted by microorganisms in the external environment, and at the same time allow air to pass through to facilitate the survival, growth, observation and detection of cells or microorganisms. Materials for making petri dishes include glass, synthetic resins, quartz, and corrosion-resistant metals (rarely used). [0003] figure 1 and figure 2 There are two existing common petri dish structures. [0004] figure 1 The culture dis...

Problems solved by technology

This requires operators to have a high degree of proficiency and to be very careful, but it is still prone to the following unfavorable situations: (1) long-term operation figure 1 When the petri dish with smooth surface is prone to slipping, etc., it is easy to operate for a long time figure 2 When the petri dish is placed in the petri dish, it is easy to accidentally grab the dish cover 1 but not the hand ring 3. The consequence is that the culture in the petri dish may be polluted, and the petri dish may be damaged if it is serious; (2) because the dish The body 1 is on the user's left hand, so the left hand cannot cooperate to participate in the precise operation when the right hand holds the pipette gun for operation; and (3) it is difficult to control the size of the opening when opening and closing the lid 1, and it is easy for external pollutants to enter inside the petri dish

These conditions will affect the process and results of biological experiments
