Problems solved by technology

However, cotton swabs or filter paper cannot completely release the collected microorganisms, which may easily cause incomplete cultivation of cultivable microorganisms; in addition, the sampling of microorganisms on the surface of objects requires aseptic operation, while cotton swabs or filter paper are used in the collection and elution of microorganisms. During the process, it is easy to be polluted by environmental microorganisms, and it is difficult to meet the requirements of aseptic operation; these shortcomings will cause the deviation of the microbial test results on the surface of the object
In addition, the operation process of the above method is cumbersome and inefficient, which easily causes waste of human resources
When the number of colonies of the target culture grown in the culture medium in the petri dish is huge, the counting process of the colonies is more cumbersome

Embodiment Construction

[0009] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the described embodiments are only used to explain the present invention, and all simplifications or equivalent changes based on the technical solutions of the present invention fall within the protection scope of the present invention.

[0010] In the discussion of specific embodiments, the shape of the split-type easy-pressing hand-held fan-shaped counting surface sampling culture dish is preferably a circle, but those familiar with the art should recognize that the present invention is also applicable to such as ellipse shape, rectangle or other suitable shape for Petri dishes.

[0011] The invention discloses a split-type easy-to-press hand-held fan-shaped counting surface sampling petri dish, which comprises...

Abstract

The invention discloses a split type easy-to-press handheld surface sampling petri dish based on sector counting. The petri dish comprises a dish bottom and a dish cover. When being stressed, at leastone transverse crack opening and at least one longitudinal crack opening formed in at least one first dish bottom side wall can be split, a movable dish bottom side wall is separated, and the at least one first dish bottom side wall is lower than the plane of a solid medium, so that surface microorganism sampling operation is simpler and more convenient; the dish bottom and the dish cover can bemore convenient to open or buckle by cooperation of at least one first gripper and at least one second gripper; the movable dish bottom side wall can be more convenient to move by at least one press boss, and the counting process of colonies can be simplified by radial lines.

Description

technical field [0001] The invention relates to an experimental equipment, in particular to a split-type easy-to-press hand-held fan-shaped counting surface sampling petri dish. Background technique [0002] Petri dish is one of the most widely used experimental equipment in biology. It is often used for the culture test of microorganisms on the surface of food packaging materials, tableware, etc., and the sampling of microorganisms on the surface of the object is usually wiped with a sterile cotton swab on the surface of the object to be tested, or Use sterile filter paper to stick to the surface of the object to be tested, and then transfer the cotton swab or filter paper to the buffer solution for eluting to achieve the purpose of sampling. However, cotton swabs or filter paper cannot completely release the collected microorganisms, which may easily cause incomplete cultivation of cultivable microorganisms; in addition, the sampling of microorganisms on the surface of obj...
