The tissue culture vessel
Technical field
The utility model relates to the tissue culture device of plant, relates in particular to the tissue culture vessel.
Background technology
At present, known tissue culture vessel are generally discoid, the common plastics material, the two sides is smooth, all there is screw thread in the culture dish tegmental wall inboard and the culture dish wall outside, can keep culture dish airtight after lid screws, and this kind design and daily plastic ware there is no remarkable difference.Though this kind design can keep bacterium can't enter culture dish, the circulation that has also completely cut off air and moisture simultaneously can't be satisfied the requirement of plant tissue to circulation of air and moisture, is unfavorable for the cultivation of plant tissue.
Summary of the invention
The utility model is ventilative at existing Plant Tissue Breeding vessel, water penetration is relatively poor, the shortcoming of moisture humidity in can't the flexible modulation culture dish, provide a kind of and some permeability cells have been set by covering at the tissue culture ware, and in permeability cell, place absorbent cotton, can guarantee the illumination abundance like this, stop that bacterium enters the destruction plant tissue, can guarantee the circulation of air and moisture again, can also regulate the tissue culture vessel of the temperature humidity in the culture dish by opening and closing air-vent simultaneously.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
The tissue culture vessel, the culture dish lid that comprises culture dish and cooperate with culture dish, described culture dish has covered more than one permeability cell, the diameter of permeability cell is 2-6mm, permeability cell runs through culture dish lid and vertical with the plane, circular flat cover plate place of culture dish lid, there is a cavity inside of permeability cell, is placed with absorbent cotton in the cavity.Culture dish covers permeability cell is set, and in permeability cell, place absorbent cotton, can guarantee the illumination abundance like this, stop that bacterium enters the destruction plant tissue, can guarantee the circulation of air and moisture again, can also regulate the tissue culture vessel of the temperature humidity in the culture dish by opening and closing air-vent simultaneously.
As preferably, described culture dish covers and is provided with a permeability cell, and permeability cell is positioned at the center of culture dish lid, and permeability cell covers with culture dish and passes through integrated injection molding.The material of culture dish lid is plastics, and culture dish lid and permeability cell be by integrated injection molding, has convenient for productionly, processes simple advantage.
As preferably, the material of described culture dish lid is plastics, and culture dish covers and is provided with four permeability cells, and permeability cell evenly distributes around the center of culture dish lid, and permeability cell covers with culture dish and passes through integrated injection molding.Culture dish lid and permeability cell be by integrated injection molding, has convenient for productionly, processes simple advantage.
As preferably, described culture dish lid lateral wall is provided with anti-skidding line, and culture dish lid madial wall is provided with screw thread, and the culture dish lid spins by screw thread with culture dish.
As preferably, described permeability cell comprises outer permeability cell that stretches out the culture dish lid and the permeability cell that is positioned at the culture dish lid, and the height that outer permeability cell stretches out the culture dish lid is 5-20mm, the thickness that the height of interior permeability cell covers less than culture dish.
As preferably, described culture dish covers ventilated membrane is set.Ventilated membrane can guarantee the circulation of air and moisture, can also regulate the tissue culture vessel of the temperature humidity in the culture dish simultaneously.
The utility model is owing to adopted above technical scheme, have significant technique effect: the lid material of tissue culture vessel is plastics, transparent, help the irradiation of sunlight, be convenient to simultaneously observe, culture dish covers some permeability cells is set, help the circulation of air, the upper opening place of permeability cell is provided with ventilated membrane, stops when can guarantee to breathe freely that bacterium enters invaded tissue, permeability cell can freely be selected to open and close, and helps humidity and temperature in the free adjustment culture dish.
