Description

Microbial culture dish

Technical Field

The utility model relates to a biology experimental apparatus field, concretely relates to microbial cultivation ware.

Background

Many kinds of culture dishes of microorganism are culture dishes and add a non-fixed lid as a set, when liquid inoculum is required to be evenly tiled and inoculated to the culture dish, a microorganism coater (or called L-shaped coating rod, generally, disposable and can be sterilized and then repeatedly used) is required to be additionally used to rotate the microorganism coater, so that the liquid can be uniformly coated on a culture medium, and the condition that the culture medium is crushed or the coating is uneven can be caused due to improper strength and distance control in the coating process. If a disposable sterile microbial applicator is used, the individual packages need to be unpacked during operation, increasing the workload. If a sterilizable reusable microbial applicator is used, sufficient inventory needs to be ensured, and the applicator after use needs to be self-sterilized and self-monitored for sterilization effectiveness. The workload is large, and when the sterilization is not in place, the culture analysis can be directly influenced.

The following further description of the present invention:

this novel culture dish lid combines together microorganism coating unit, and culture dish covers fixed microorganism coating piece promptly. The culture dish cover can be designed according to the diameter and the height of the culture dish matched with the culture dish cover for use, so that the distance between the microorganism coating sheet and the culture medium is fixed, and the condition that the culture medium is crushed can be effectively avoided. The smooth rounded or drop-shaped contact surface reduces the residue of liquid inoculum on the microbial applicator. During the use, the culture dish is stood still at the experiment table top, inoculates the culture medium on, covers the culture dish lid, makes coating piece and culture contact, then rotatory culture dish lid, can be with on the even coating of inoculum is to the culture medium, make the coating operation more convenient.

The coating piece can be connected with dish lid fixed connection, also can dismantle the connection, and as the optimization scheme, adopt to dismantle the connection then can select the coating piece of different size side lengths according to the thickness of culture medium. The detachable connection mode can be various, and preferably, the two ends of the coating sheet are respectively clamped and connected with the dish cover or the coating sheet is directly clamped and connected with the dish cover.

The utility model discloses can carry out size customization, extensive applicability according to different culture dishes. After sterilization, the culture dish is matched with a package to ensure the sterilization effect. Disposable, the simple operation, personnel's efficiency can promote.

Compared with the prior art, the utility model has the advantages that:

the existing bacteria spreader is separated from the culture dish cover, and the operation of inoculating the culture is as follows: opening a cover, inoculating, closing the cover, disassembling a bacteria applicator, opening the cover, coating and closing the cover. And use the utility model the operation behind the culture dish does: and opening the cover, inoculating, closing the cover and rotating the culture dish to cover for a circle. The operation steps are simplified, the efficiency is improved, the operation of repeatedly opening and closing the cover is avoided, and the possible pollution in the inoculation process is reduced.
