Abstract
The utility model discloses a culture medium sterilization apparatus, including bottle lid and bottle, be equipped with ventilative filter membrane on the bottle lid, be equipped with heat -resisting rubber pad and hollow rubber stopper in the bottle lid, the hollow rubber stopper is located the below of ventilative filter membrane, and with the bottleneck of bottle closely cooperates, the bottleneck upper end is equipped with the plastics protection ring, and the lower extreme is equipped with heat -resisting rubber ring. The utility model discloses a three sealed departments between bottle lid and the bottleneck have strengthened this sterilization apparatus's leakproofness greatly, the ventilative filter membrane device that is equipped with on the bottle lid can reduce the possibility that the culture medium sprays in time with overboard steam drain in the bottle, the utility model discloses but reuse has saved experiment consumptive materials such as sealing membrane and nylon rope, the cost is reduced.
Description
Technical field
This utility model relates to labware technical field, particularly, relates to a kind of culture medium sterilizer.
Background technology
Culture medium is the nutriment of the artificial preparation growing for microorganism, plant tissue and animal tissue and maintain, generally all contain carbohydrate, nitrogen substance, inorganic salt (comprising trace element) and vitamin and water etc., therefore, culture medium carries out microorganism and animal vegetable tissue cultivation conditio sune qua non in biological experiment.But in biological experiment, usually by medium sterilization is insufficient etc., problem causes for the pollution of culture medium or culture, this creates very large impact smoothly on the growth of culture and biological experiment.So the bactericidal unit that culture medium is scientific and reasonable and sterilization process are the bases that biological experiment carries out smoothly.
At present, the culture medium sterilizer that laboratory is conventional mainly contains two kinds, one is " conical flask+sealed membrane " device, this device needs the bottleneck of artificial sealed membrane to conical flask to wrap up, although the object of medium sterilization can be reached, but often wash sealed membrane open because wrapping up shaky, thus cause sprinkling and the pollution of culture medium, especially the sprinkling of agar culture medium can cause the blocking of autoclave drain valve; It two is " blue lid reagent bottle " device, be contained in blue lid reagent bottle by culture medium and carry out disinfecting action, although this device is more time saving and energy saving than the first device, and effect might as well, but make because it lacks gas permeable devices culture medium be sprayed onto outside, do not reach desirable sterilization effect.
Utility model content
The purpose of this utility model is the shortcoming that exists according to prior art and the one that provides is easy and simple to handle, sealing and sterilization effect is good and the reusable culture medium sterilizer of energy.
The technical solution of the utility model is: a kind of culture medium sterilizer; comprise bottle cap and bottle; described bottle cap is provided with ventilative filter membrane; heat resistant rubber pad and hollow rubber plug is provided with in described bottle cap; described hollow rubber plug is positioned at the below of described ventilative filter membrane; and closely cooperate with the bottleneck of described bottle, described bottleneck upper end is provided with plastics protection ring, and lower end is provided with heat resistant rubber ring.
Preferably, described heat resistant rubber pad and hollow rubber plug are structure as a whole.
Preferably, described bottle cap and bottle adopt thread connecting mode or lock connection mode.
Preferably, described bottle is carved with containing mark, sterilizing can be carried out to culture medium quantitatively.
The beneficial effects of the utility model: the 1. three seals place between bottle cap and bottleneck greatly strengthen the sealing of this bactericidal unit; 2. steam in bottle can be discharged by bottle cap is provided with ventilative filter membrane device in time, reduces the probability that culture medium is sprayed; 3. helicitic texture makes this device more fast and convenient in operation; 4. compared with prior art, this device convenience and high-efficiency, practicality is stronger; 5. this utility model can reuse, and saves the experiment such as sealed membrane and nylon rope consumptive material, reduces cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of this utility model culture medium sterilizer;
In figure: 1 heat resistant rubber pad; 2 ventilative filter membranes; 3 bottle caps; 4 hollow rubber plugs; 5 bottleneck inwalls; 6 plastics protection rings; 7 bottleneck outer walls; 8 heat resistant rubber rings; 9 bottles.
Detailed description of the invention
By reference to the accompanying drawings the embodiment that this utility model provides is described in further detail:
A kind of culture medium sterilizer; comprise bottle cap and bottle; described bottle cap is provided with ventilative filter membrane; heat resistant rubber pad and hollow rubber plug is provided with in described bottle cap; described hollow rubber plug is positioned at the below of described ventilative filter membrane; and closely cooperate with the bottleneck of described bottle, described bottleneck upper end is provided with plastics protection ring, and lower end is provided with heat resistant rubber ring.
As shown in Figure 1, be the structural representation of a kind of embodiment of this utility model culture medium sterilizer; A kind of culture medium sterilizer, comprises the heat resistant rubber pad 1 be embedded in bottle cap, heat resistant rubber ring 8 and bottle 9 below the high temperature resistant ventilative filter membrane 2 be positioned on bottle cap, bottle cap 3, the hollow rubber plug 4 integrated with rubber blanket 1, bottleneck inwall 5, bottleneck plastics protection ring 6, bottleneck outer wall 7, bottleneck.Bottle cap 3 is made up of high-temperature resistance plastice, bottle 9 is made up of pyroceram, and be connected by the helicitic texture of bottleneck outer wall 7 with bottle cap 3 inwall between bottle cap 3 and bottle 9, namely bottle to open or close be the realization that relatively rotates by between bottle cap 3 and bottle 9, bottle 9 is carved with containing mark, sterilizing can be carried out quantitatively to culture medium, wherein, bottle cap and bottle also can be connected for buckle structure, snap close is provided with below bottleneck, when bottle cap presses down, bottle cap can pin by snap close, it is made no longer to be moved, after sterilizing, separate opening lock catch, bottle cap is directly opened.
The culture medium made in use will first be contained in sterilizing bottle by this utility model, note the heap(ed) capacity making it can not exceed bottle 9 to limit, then by the screwed tight of bottle cap 3 on bottleneck outer wall 7, heat resistant rubber pad 1 is made all can be in sealing state with the bottom of bottleneck plastics protection ring 6, hollow rubber plug 4 and bottleneck inwall 5, bottle cap 3 and these three junctions of heat resistant rubber ring 8; Then this bactericidal unit is put into autoclave and carry out disinfecting action, in sterilization process, the steam that in bottle, culture medium produces can constantly be discharged outside bottle by hollow rubber plug 4 and ventilative filter membrane 2, make pressure inside and outside bottle 9 consistent, after sterilizing terminates, taken out, reverse twist-off closure 3 when being cooled to uniform temperature, after culture medium in bottle 9 being poured out, cleaning bottle 9 and bottle cap 3, reuse after it dries.
In this description, this utility model is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, description and accompanying drawing are regarded in an illustrative, rather than a restrictive.
