A kind of Petri dish box
The present invention relates to Bioexperiment instrument and equipment field, more particularly to a kind of Petri dish box.
Culture dish is the commonly used glass experiment equipment of Microbiological Lab, is mainly used to cultivate various microorganisms.It is logical
The process of microbial inoculant culture is as follows in the case of often：(1) it cleans the culture dish dried to be wrapped up with newspaper, pressure cooker sterilizing；(2)
Culture medium flat plate is made in superclean bench, to be solidified (because of laboratory superclean bench limited amount, tablet solidified
Other people can arbitrarily use in journey)；(3) it is inoculated with；(4) inoculated culture dish is put into tying in disposable freshness protection package；(5)
Being transferred in incubator culture, (because laboratory cultures box number is limited, various microorganisms are put together culture, Er Qiepei
Other people can arbitrarily open incubator during supporting).There are obvious shortcomings for the above whole operation process：(1) culture dish sterilizing does not have
There is fixed container, can only be wrapped up with newspaper, water inlet is easy in not only time-consuming and laborious but also sterilization process, culture dish is caused to scatter
Sterilizing is not thorough；(2) microbiological contamination is easy in good culture medium flat plate process of setting；(3) disposable freshness protection package wrapping, not only wastes
And it is airtight, it is unfavorable for the growth of aerobic bacteria；(4) various microorganisms put together and cultivate not only easy microbiological contamination in incubator,
And aerobic-anaerobic condition can not achieve.
In view of the foregoing deficiencies of prior art, the purpose of the present invention is to provide a kind of Petri dish boxes, for solving
The problems of the prior art.
In order to achieve the above objects and other related objects, the present invention provides a kind of Petri dish box, including box cover, pedestal and training
Ware frame is supported, the box cover is cylinder, interior hollow, top closure, and side wall inner surfaces lower end is provided with screw thread, is arranged among side wall
There is ventilation switch, there are two the ventilation switch, symmetrical distribution；The pedestal is solid cylinder, and side surface upper end is set
It is equipped with screw thread, top is provided with jack, and jack is the 3/4 of substructure height not through entire pedestal, depth, and the jack has three
A, the symmetrical distribution of two of which jack, third jack is distributed in the first two jack and connects among the circular arc to be formed, described
Pedestal side surface threaded upper ends are corresponding with cover side wall inner surface lower thread, and box cover is opened and closed by screw thread；The culture dish
Frame is made of pillar and more than one pallet, and pillar and pallet are integral structures, can not be dismantled, and there are three the pillars, point
For cloth in tray edge, lower end protrudes from pallet, and upper end does not protrude, wherein the first pillar and the second pillar are right at left and right sides of pallet
Distribution, third pillar is claimed to be distributed between the first pillar, the second pillar, the pillar is corresponding with base jack insertion type, culture
Ware frame is fixed on the base by pillar, and detachably, the pallet has shirt rim, and there are 30 degree of sector notch at edge, with third branch
Column is centrosymmetric.
Preferably, the ventilation switch is made of plate, slot and venthole.
It is furthermore preferred that the plate and slot match.
More there is a choosing, plate upper end centre position opens that there are one grooves.
More there are choosing, the venthole to be opened on cover side wall, one layer of aperture is adhered on the inside of the wall of corresponding ventilation hole site
For 0.2 micron of ultrafiltration membrane.
Preferably, the substructure height≤box cover height.
Preferably, Petri dish box is cylinder, basal diameter >=its height, basal diameter ＞ pallet diameters.
Preferably, a diameter of 5cm-17cm of the pallet, shirt rim height are 1cm, between pallet between be divided into 4cm.
Preferably, each component of Petri dish box, including box cover, pedestal and culture dish frame are all made of heat-resisting material and are made.
The present invention provides a kind of Petri dish box, the Petri dish box both can be used for the entire mistake of microbial inoculant culture
Journey can also be used alone as culture dish sterilization container, and culture medium flat plate solidifies container or culture vessel is isolated in microorganism, reduces
Contamination rate.On the whole, the invention has the advantages that：
(1) Petri dish box provided by the invention, can use manpower and material resources sparingly as culture dish sterilization container, easily put and easily take, go out
Bacterium is thorough；
(2) Petri dish box provided by the invention, when being used as culture medium flat plate solidification container, good tablet is placed on the inside can
It is placed on that any position etc. is to be solidified, the possibility of microbiological contamination can also be reduced by being both not take up superclean bench space；
(3) Petri dish box provided by the invention, when being used as microorganism isolation culture vessel, microorganism is placed in big incubator
Anaerobic-aerobic condition can be adjusted when culture as needed and reduces the possibility for polluting other miscellaneous bacterias；
(4) Petri dish box provided by the invention, it is easy to operate when being used for the whole process of microbial inoculant culture,
And culture dish is in gnotobasis always, substantially reduces microbiological contamination risk, improves experiment success rate.
