Description

Mesh-type air filtration plug

The utility model is called for short " mesh plug ", and it relates to microbial technology field such as industry, agricultural, medical and health, particularly a kind of stopper that is applicable to bottle, pipe and the container of having cultivated gas fungi (Fungus), bacterium (bacteria).

Fungi, bacterium majority have belonged to the gas type, promptly need certain oxygen in incubation.But when oxygen is provided, tends to airborne assorted cingula is gone into to cause the cultivation fungi pollution in the culture vessel, and make it to scrap.At present, the conventional practice that solves this contradiction is at bottle, pipe, sack plug tampon, wrapping multilayer gauze or paper, this two classes material is organic matter because of itself, it is the culture matrix of mould, especially in the summer of high temperature, tide temperature, tampon, gauze, paper itself very easily mildew and cause bacterial classification cultivate in or cultivate pollution in the preservation after finishing.Therefore ventilation fails to be satisfactorily resolved with the problem of filtering assorted bacterium all the time.

Goal of the invention of the present utility model provides a kind of physics and chemistry and strainability all is better than traditional cotton yarn, paper plug, can finely be applicable to the mesh plug of bottle, pipe, bag or inoculating hood (chamber) that germ is cultivated.This type of novel stopper is with existing all kinds of stoppers are all different in the past, and it is mildew, nonhygroscopic, high temperature resistant (below 130 ℃) not, the corrosion of not being afraid of UV-irradiation and various chemical disinfection medicaments.Can breathe freely, satisfy that various good gas fungies, bacterial solids are cultivated or during Liquid Culture to the demand of oxygen, can filter out airborne assorted bacterium spore and mycelia fragment again, keep the assorted bacterium ecology environment of nothing in the culture vessel, the test of cultivation or production bacterium yield rate are greatly improved.Material is water insoluble simultaneously, but the boiling water washing, sterilization back repeated use, cost is low, making is simple, inoculation is easy to operate.

Goal of the invention of the present utility model is achieved in that size, the depth of the utility model according to used culture bottle, pipe, sack, inoculating hood (chamber) hole, select degree of tightness, the supporting mesh plug of length with it for use, its height is 10 millimeters to 500 millimeters, top diameter is 8 millimeters to 400 millimeters, diameter at butt end is 10 millimeters to 500 millimeters a round platform, wherein A type whole body surface is open cell type, and the Type B upper and lower surface is an open cell type, and circumferential surface is an obturator-type.

The utility model plug also can be filled in the air extractor vent in inoculating hood, the ventilation hole of transfer room in bottle pipe, the sack of the seed bottle of carrying out the cultivation of aerobe class, triangular flask, test tube, strain bag etc., purifies air to reach, and the purpose of sterile chamber ecology environment is provided.Mesh plug is processed into by High molecular material polyurethane foamed rubber.

Concrete using method of the present utility model is: after seed bottle, triangular flask, test tube, strain bag are contained culture, the mesh plug of promptly selecting fitted vessel mouth size, length for use is its bottle, pipe, sack beyond the Great Wall, thereafter high-temperature steam sterilization, sterilization finish to enter that inoculating hood (chamber) is preceding soaks mesh plug so that bottle, the mouth of pipe unlikely charing of mesh plug during the calcination sterilization on alcohol lamp flame before the inoculation with lysol or formalin.Transfer to mesh plug before the inoculation, will stopple after the inoculation fill in bottle, the mouth of pipe gets final product.When inoculating hood (chamber) uses as air filter, should be regularly with using instead after disinfectant immersion and the boiling water washing.

Unique function of the present utility model; Permeability to air obviously is better than all kinds of porous plugs of traditional cotton, yarn, paper making.Its performance is to adopt the interior aerobe silk growth of the bottle pipe of mesh plug vigorous, and the bacterium colony expansion rapidly.The effect of the assorted bacterium of filtered air is better than above-mentioned traditional stoppers, and especially in damp and hot summer, pollution rate reduces greatly.The no mildew phenomena of mesh plug itself.

The utility model: cost is low, easy to operate, application is wide, produce bacterium output height, is easy to industrialized mass, obtains to widen the two-way economic benefit on the material use and the raising mushroom output value.

Provide accompanying drawing of the present utility model below.

Fig. 1 schematic appearance of the present utility model.

Fig. 2 cross-sectional figure of the present utility model.

Fig. 3 sectional side elevation of the present utility model.

Below in conjunction with drawings and Examples, the utility model is described in further detail.

The utility model is made up of the mesh plug series of some different models, specification, the mesh plug height is 10 millimeters to 500 millimeters, top diameter is 8 millimeters to 400 millimeters, and diameter at butt end is the round platform of 10 millimeters to 500 millimeters different sizes, and wherein A type whole body surface is open cell type.The Type B upper and lower surface is an open cell type, and circumferential surface is an obturator-type.

The utility model plug is in bottle, pipe, the sack of the seed bottle of carrying out the cultivation of aerobe class, triangular flask, test tube, strain bag etc., also can fill in the air extractor vent in inoculating hood, the ventilation hole of transfer room, purify air to reach to feed, the purpose of sterile chamber ecology environment is provided.Mesh plug is processed into by High molecular material polyurethane foamed rubber.

Concrete using method of the present utility model is: after seed bottle, triangular flask, test tube, strain bag are contained culture, promptly select fitted vessel mouth size for use, the mesh plug of length.Select the mesh plug of high 40 millimeters, 16 millimeters of microcephalies, 26 millimeters in major part for use as 20 millimeters of diameters, long 200 millimeters test tube.And for example capacity is 750 milliliters, and it is high 50 millimeters that bore is that 30 millimeters seed bottle should be selected for use, 28 millimeters of microcephalies, the mesh plug that major part is 40 millimeters.The mesh plug of plug strain bag should be selected for use according to the bore of strain bag neck ring.Vessel port high-temperature vapour sterilization at once after the mesh plug beyond the Great Wall, sterilization finish to enter that inoculating hood (chamber) is preceding to soak mesh plug with lysol or formalin, so that bottle, the mouth of pipe are on alcohol lamp flame during the calcination sterilization before the inoculation, and the unlikely charing of mesh plug.Extract mesh plug before the inoculation, will mesh plug after the inoculation fill in bottle, the mouth of pipe gets final product.When inoculating hood (chamber) uses as air filter, should be regularly with using instead after disinfectant immersion and the boiling water washing.

Unique function of the present utility model; Permeability to air obviously is better than all kinds of porous plugs of traditional cotton, yarn, paper making.Its performance is that the interior aerobe silk growth of bottle, pipe of adopting mesh plug is vigorous, and the bacterium colony expansion rapidly.The effect of the assorted bacterium of filtered air is better than above-mentioned traditional stoppers, and especially in damp and hot summer, pollution rate reduces greatly.The no mildew phenomena of mesh plug itself.

The utility model: cost is low, easy to operate, application is wide, produce bacterium output height, is easy to industrialized mass, obtains to widen the two-way economic benefit on the material use and the raising mushroom output value.
