The upper portion of the culture chamber (3) is provided with an upper cover (5), the upper cover (5) is a glass piece, and the side wall of the culture dish is provided with a through hole (4) for extending into the inoculation, The through hole (4) is in communication with the fungal culture chamber (3).

As a modification of the above technical solution, the axial direction of the through hole is perpendicular to the longitudinal direction of the slide glass.

As an improvement of the above technical solution, the petri dish has a circular cross section.

As a modification of the above technical solution, the cover glass has a circular shape and a diameter larger or smaller than the diameter of the culture dish.

As a modification of the above technical solution, the cover glass is ultrasonically welded to the upper portion of the culture dish.

As an improvement of the above technical solution, the slide glass is provided with a frosted area on both sides.

As a modification of the above technical solution, the slide glass and the culture dish are each made of a light transmissive polystyrene material.

As an improvement of the above technical solution, the slide has a length of 50 to 100 mm and a width of 20 to 30 mm.

As an improvement of the above technical solution, the four corners of the slide have a chamfer.

As an improvement of the above technical solution, the slide has a length of 50 to 100 mm and a width of 20 to 30 mm.

As an improvement of the above technical solution, the culture dish has a diameter of 15 to 25 mm and a height of 2 to 5 mm, and the through hole has an inner diameter of 1.0 to 4.0 mm.

As an improvement of the above technical solution, one side of the slide glass is further provided with a trademark area marked with a trademark.

In contrast to the prior art, the present invention provides an overcapped fungal culture apparatus which utilizes a glass sheet or other material having a thinner thickness by modifying the upper lid of the culture dish. When the culture dish is placed under a microscope, the microscope is made thinner, so that the microscope is closer to the fungus for observation, so that the morphology of the fungus can be observed more clearly under the same multiple microscope, thereby achieving the use of a low power microscope. Instead of observing the effect of a high power microscope, the cost of purchasing a high power microscope is reduced, and significant economic benefits are obtained.

detailed description

As shown in Figure 1 The top cover fungus culture apparatus according to the present invention comprises a slide glass 1 on the front side of which a culture dish 2 is disposed, the slide glass 1 and the culture dish 2 are integrally formed, and the slide glass 1 is located under the culture dish 2 As its chassis, both the slide 1 and the petri dish 2 are made of a light transmissive polystyrene material.

Further, the side wall of the culture dish 2 is provided with a through hole 4 for extending into the inoculation, wherein the axial direction of the through hole 4 is perpendicular to the longitudinal direction of the slide glass 1, and the through hole 4 is used for inoculating the needle to advance the fungus into the needle. Inoculation in a solid medium, the substance in the fungal culture chamber 3 shown in Fig. 2 is not volatile due to the small pore size. The overcapped fungal culture apparatus of the present invention further includes an upper cover 5 made of glass and ultrasonically welded to the top end of the side wall of the culture dish 2. In addition, the upper cover 5 can be replaced with a cover glass, and the side wall of the culture dish 2 can be sealed with paraffin wax to meet different requirements, and is also closer to the conventional microscopic observation mode.

Referring further to Figure 2, the integrally formed slide 1 and the culture dish 2 form a fungal culture chamber 3, the through hole 4 is in communication with the fungal culture chamber 3, and both sides of the slide 1 are provided with a frosted area 7 for easy marking. Further, one side of the slide glass 1 is provided with a trademark area 8 for marking a trademark, the size and position of which are determined as needed.

As shown in FIG. 3, according to a preferred embodiment of the present invention, the outer diameter of the upper cover 5 is smaller than the outer diameter of the culture dish 2 and larger than the inner diameter of the culture dish 2 to ultrasonically weld the upper cover 5 to the culture dish 2.
