Abstract
The utility model relates to a kind of wide-mouth liquid nitrogen container with net formula moving liner, be a kind of can be from wide-mouth liquid nitrogen container the aid of quick collection transfer tobacco tissue sample, be applicable to biology field, it is characterized in that: in liquid nitrogen container, be furnished with the soft quality string bag, the upper edge hole of the string bag installs a branch of mouthful of rope by snap ring, on bundle mouthful rope, be equipped with and tighten sling, the upper edge hole of the string bag turns over the tank mouth place that is placed in liquid nitrogen container and both can be strapped on tank mouth by tightening sling, can the string bag directly be put forward from tank by tightening up a bundle mouthful rope again.Utilize the utility model can collect quickly and easily the Tissues of Tobacco sample in wide-mouth liquid nitrogen container, can leach fast liquid nitrogen and collect sample, need not from liquid nitrogen, fish for one by one again sample, not only save the plenty of time, but also ensured operating personnel's personal safety.
Description
Technical field
The utility model relates to a kind of wide-mouth liquid nitrogen container with net formula moving liner, be a kind of can be from wide-mouth liquid nitrogen container the aid of quick collection transfer tobacco tissue sample, be applicable to biology field.
Background technology
While gathering Tissues of Tobacco sample in the wild, need first sample is put into liquid nitrogen container snap frozen and store, after transporting laboratory back, then sample is transferred to from liquid nitrogen container to-80 DEG C and saves backup.From wide-mouth liquid nitrogen container, collect at present and when transfer tobacco tissue sample, after conventionally needing first the sample in liquid nitrogen container to be poured into uncovered foam box together with liquid nitrogen, re-use the long bamboo tweezer sample in gripping liquid nitrogen one by one, transfer them in ultra low temperature freezer.Because liquid nitrogen can become gaseous state from liquid state at normal temperatures rapidly, therefore when operating personnel are when toppling over sample in liquid nitrogen container and liquid nitrogen in uncovered foam box, a large amount of nitrogen that liquid nitrogen volatilization forms can seriously hinder people's sight line, bring very big inconvenience to gripping and the transfer of subsequent sample.Operating personnel can only judge reluctantly the position of sample in liquid nitrogen in aerosol, have greatly extended the transfer time of sample.If sample shift liquid nitrogen for a long time in the poor confined space of circulation of air in, the nitrogen that liquid nitrogen volatilization forms can be full of whole space gradually, and oxygen concentration in air is reduced, and likely can cause operating personnel's anoxia asphyxia.
Utility model content
A kind of wide-mouth liquid nitrogen container with net formula moving liner that the purpose of this utility model provides based on above-mentioned current condition just, utilize this device can collect quickly and easily the Tissues of Tobacco sample in wide-mouth liquid nitrogen container, can leach fast liquid nitrogen and collect sample, need not from liquid nitrogen, fish for one by one again sample, not only save the plenty of time, but also ensured operating personnel's personal safety.
The purpose of this utility model is achieved through the following technical solutions: a kind of wide-mouth liquid nitrogen container with net formula moving liner, comprise a wide-mouth liquid nitrogen container, in liquid nitrogen container, be furnished with the soft quality string bag, the upper edge hole of the string bag installs a branch of mouthful of rope by snap ring, on bundle mouthful rope, be equipped with and tighten sling, the upper edge hole of the string bag turns over the tank mouth place that is placed in liquid nitrogen container and both can be strapped on tank mouth by tightening sling, can the string bag directly be put forward from tank by tightening up a bundle mouthful rope again.
In the utility model, the quantity of snap ring is three; The described soft quality string bag is to be formed by low temperature material braiding, to adapt to liquid nitrogen cryogenics environment.
In use, the soft quality string bag is put into wide-mouth liquid nitrogen container, string bag upper edge hole is taken advantage of a situation and is turned up, and tightens up bundle mouthful rope with sling simultaneously, makes pocket mouth firmly be fixed on liquid nitrogen container tank mouth, and the string bag hangs in tank naturally.When use, in tank, pack liquid nitrogen and tobacco product into, in the time that needs shift out tobacco product, liquid nitrogen is leached by mesh bag, and sample is directly collected in the string bag.Unclamp sling, this string bag can be taken out from liquid nitrogen container together with sample, tighten up bundle mouthful with sling and restrict, tighten sack, put into-80 DEG C and save backup.Use the utility model can quick collection and shift the Tissues of Tobacco sample in liquid nitrogen container, simple to operation, save the plenty of time, reduce the liquid nitrogen aerosol that the produces impact on operating personnel of volatilizing for a long time.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1. snap ring, 2. wide-mouth liquid nitrogen container, the 3. string bag, 4. bundle mouthful rope, 5. sling.
Embodiment
The utility model is described further below in conjunction with accompanying drawing:
As shown in the figure: a kind of wide-mouth liquid nitrogen container with net formula moving liner, comprise a wide-mouth liquid nitrogen container 2, in liquid nitrogen container 2, be furnished with the soft quality string bag 3, the upper edge hole of the string bag installs a branch of mouthful of rope 4 by three snap rings 1, on bundle mouthful rope 4, be equipped with and tighten sling 5, the upper edge hole of the string bag turns over the tank mouth place that is placed in liquid nitrogen container and both can be strapped on tank mouth by tightening sling, can the string bag 3 directly be put forward from tank by tightening up a bundle mouthful rope 4 again.
The described soft quality string bag is to be formed by low temperature material braiding, to adapt to liquid nitrogen cryogenics environment.
