Abstract

The utility model relates to a culture dish, in particular to a disposable and aseptic double-layer culture dish with an inner ring arranged internally. The culture dish is composed of a dish cover and a dish bottom, wherein, the dish cover is cylindrically shaped, the inner ring is arranged at the central part of the dish cover, the inner ring is in the shape of a truncated cone, and the margin of the inner ring and the upper running surface of the dish cover form a certain angle; three straight ribs are uniformly formed at the internally equal corners of the dish cover; the dish bottom is cylindrical, the outer diameter of the dish bottom is smaller than the inner diameter of the outer ring of the dish cover, and the dish bottom is covered with the dish cover during bacilli culture. The culture dish has low use cost, reduces the storage space in a package and an incubator, and decreases the expenditure; although the double-layer culture dish has simple structure, the application thereof is wide, and the double-layer culture dish has certain economic and social benefits.

Description

The aseptic double-deck culture dish of disposable use

Technical field

The utility model relates to a kind of culture dish, is provided with the aseptic double-deck culture dish of disposable use of inner ring in particularly a kind of ware lid.

Background technology

Existing culture dish all is an individual layer, for the monolayer culture ware, should draw two flat boards when carrying out microbial culture by standard usually, the one, and S.S flat board, the 2nd, TCBS flat board or sorbyl alcohol Mai Kangkai flat board etc.Because the monolayer culture ware will use two flat boards, therefore, the cost of microbial culture is than higher, and in addition, a culture dish can only carry out single sample to be cultivated, and multiple sample is cultivated then needs the polylith culture dish, so just increases the parking space that has taken in the incubator.

The utility model content

Technical problem to be solved in the utility model provides in a kind of ware lid and is provided with inner ring, pours into difficult drop-off behind the agar, can prevent dull and stereotyped in bacterium fill the air the aseptic double-deck culture dish of disposable use of growth because of steam.

For solving the problems of the technologies described above, the utility model is realized as follows: the aseptic double-deck culture dish of disposable use described in the utility model is formed at the bottom of by ware lid and ware; Described ware lid is for cylindrical, and its central authorities are provided with inner ring, and inner ring is a truncated cone-shaped, and inner ring edge and ware lid upper face are angled; It is protruding distracted that the triangle such as grade is evenly equipped with three in-lines in the ware lid; Be cylindrical at the bottom of the ware, the external diameter at the bottom of the ware is less than the internal diameter of ware lid outer ring, and during culturing bacterium, ware covers at the bottom of the ware.

Material at the bottom of described ware lid and the ware is the medical grade polystyrene.

Positively effect of the present utility model is: the inner ring of ware lid has certain angle with the upper face that ware covers, and pours into difficult drop-off behind the agar; It is protruding distracted to wait triangle to be evenly equipped with three in-lines in ware lid, and its effect is when making double-layer plate insert in 37 ℃ of incubators at last, and the water vapor in the ware can be overflowed outside the ware, prevents that dull and stereotyped interior bacterium from filling the air growth because of steam; In addition, the utility model is simple to operate, and cultivate by the standard stool usually and should draw two flat boards, and now as long as standardized double-layer plate is just passable; This culture dish use cost is low, has reduced the parking space in packing and the incubator, has reduced expense, though double-deck culture dish is simple in structure, it uses general, has certain economic benefit and social benefit.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

3 inner rings 4 were protruding distracted at the bottom of 1 ware covered 2 wares among the figure

Embodiment

As shown in Figure 1 and Figure 2, the aseptic double-deck culture dish of disposable use described in the utility model 2 is formed at the bottom of by ware lid 1 and ware; Described ware lid 1 is cylindrical, and its central authorities are provided with inner ring 3, and inner ring 3 is a truncated cone-shaped, and it is angled that inner ring 3 edges and ware cover 1 upper face; Wait triangle to be evenly equipped with three in-lines protruding distracted 4 in the ware lid 1; 2 is cylindrical at the bottom of the ware, and 2 external diameter covers the internal diameter of 1 outer ring less than ware at the bottom of the ware, and during culturing bacterium, ware lid 1 covers at the bottom of the ware above 2.

2 material is the medical grade polystyrene at the bottom of described ware lid 1 and the ware.

Using method of the present utility model is: pour into S.S agar at the bottom of ware, pour into TCBS agar at ware lid inner ring.Pour into sorbitol-MacConkey agar as covering, simultaneously separation and Culture pathogenic colibacillus, Salmonellas and Shigellae at ware.

Shape at the bottom of ware of the present utility model lid and the ware is not limited to cylindrical, no matter different, different sizes, different double-deck culture dish just occur, all within protection domain of the present utility model.

Claims

1, the aseptic double-deck culture dish of a kind of disposable use by forming at the bottom of ware lid and the ware, is characterized in that: described ware lid is for cylindrical, and its central authorities are provided with inner ring, and inner ring is a truncated cone-shaped, and inner ring edge and ware lid upper face are angled; It is protruding distracted that the triangle such as grade is evenly equipped with three in-lines in the ware lid; Be cylindrical at the bottom of the ware, the external diameter at the bottom of the ware is less than the internal diameter of ware lid outer ring, and during culturing bacterium, ware covers at the bottom of the ware.

2, the aseptic double-deck culture dish of disposable use according to claim 1 is characterized in that: the material at the bottom of described ware lid and the ware is the medical grade polystyrene.
