Abstract

A kind of modified opened type tissue culture bottle provided by the utility model, adopts the design of L-type inlet channel, can not make mushroom vertically enter in tissue culture bottle through after sterile cotton with air-flow.Sterile cotton and the design of L-type inlet channel between the looping pit of cap top ventilation use and its below thin rounded flakes, reduced the pollution probability of plant in tissue culture bottle greatly.In group training process, often can produce some not materials of easy cleaning in addition, all be gathered in the bottom of tissue culture bottle, on the one hand, culture materials is organized in the convenient insertion of larger bottleneck and taking-up, also easier cleans up in addition body bottom after use.

Description

A kind of modified opened type tissue culture bottle

Technical field

The utility model relates to a kind of modified opened type tissue culture bottle.

Background technology

Existing general tissue culture bottle, its shape is cylinder, and the bottle end, is thicker, and bottleneck is narrower, and in incubation, some that produce in incubation for some are the material of easy cleaning not, is inconvenient to scrub.And little bottleneck is difficult for taking out and inserting material, in addition, germ is the main path of group training seedling bacteria infection in process of growth through tissue culture bottle lid.Common tissue culture bottle lid, one or more aperture is arranged at its top, inside has sterile cotton or filter paper separation layer to prevent that mushroom from immersing.But there is a small amount of bacterium still can enter tissue culture bottle by sterile cotton, airless almost in tissue culture bottle in addition, mushroom just vertically falls in tissue culture bottle on medium, makes group training seedling bacteria infection.

Utility model content

The purpose of this utility model is to provide a kind of modified opened type tissue culture bottle.

Concrete technical scheme of the present utility model is as follows:

A kind of modified opened type tissue culture bottle, it is characterized in that comprising tissue culture bottle lid and body, material is all transparent plastic, wherein the outer wall of tissue culture bottle lid has the anti-slip veins of setting, inwall has screw thread, cap top has the looping pit of ventilation use, there are downward 3 millimeters of cylinder projections at the middle place of lid, its below connects a thin rounded flakes, the diameter of this thin rounded flakes is than the little 3-4 millimeter of the interior diameter of lid, between the looping pit of cap top ventilation use and its below thin rounded flakes, there is sterile cotton, prevent that mushroom from entering; Body is cylindrical, and upper and lower bore is consistent, and there is outer wall thread body upper end; The screw thread of tissue culture bottle lid inwall and the outer wall thread of body match, to install.

Below in conjunction with drawings and Examples, structure of the present utility model is further described.

Brief description of the drawings:

Fig. 1 is overall schematic of the present utility model;

Fig. 2 is tissue culture bottle lid schematic top plan view of the present utility model;

Fig. 3 is tissue culture bottle lid schematic diagram of the present utility model;

Fig. 4 is body schematic diagram of the present utility model;

In figure: 1 is tissue culture bottle lid, 2 is body, and 3 is cylinder projection, and 4 is thin rounded flakes, and 5 is the screw thread of tissue culture bottle lid inwall, 6 looping pits for ventilation use, 7 outer wall threads that are body.
