Description
Technical field
The utility model is related to a kind of liquid nitrogen frozen device, especially a kind of liquid nitrogen container specimen storage device.
Background technology
Liquid nitrogen frozen is to inhale thermal property using the nitrogen ultralow temperature of liquid, and biomaterial is immersed into liquid nitrogen, life is made
Object material freezes, generally 20min or so can fully charge, and since the time freezed is short, the ice crystal of generation is just very thin
Small, freezing speed is more than the seepage velocity of intraor extracellular steam, and intraor extracellular generates ice crystal simultaneously, therefore makees without destruction to cell
With biomaterial can also normally recover after defrosting.Just because of this, liquid nitrogen has been widely used for biology, medical treatment, food etc. at present
In terms of the material processing in field.
Common biomaterial specimen storage mode is at present：There is the preservation pipe of strain to be encapsulated into beanbag storage,
The label with refrigeration material information is sticked outside beanbag, again by cloth after having tied up sack with a long rope
Bag is placed into liquid nitrogen container, and the other end of rope is then shelved on outside liquid nitrogen container, in order to pick and place.This mode is more original, deposits
In shortcomings：1. with for a long time, cloth bag sinks to liquid nitrogen pot bottom and leads to not take out freezing strain after rope is broken；②
A piece rope corresponds to a cloth bag, and winding, which easily occurs, when freezing plurality of target strain in liquid nitrogen container, between more ropes causes
Pick and place inconvenience；3. fold is uneven on cloth bag, label is easy to fall off, and makes experimenter can not see clearly what strain filled in cloth bag；
4. since liquid nitrogen temperature is extremely low, operating personnel will take strain with professional gloves, and with gloves when unlocks the mistake of cloth bag rope
Cheng Jiwei is inconvenient.5. it is relatively lighter due to the material characteristic of cloth bag, air is housed in cloth bag, can usually float on liquid nitrogen surface, it cannot
Guarantee is submerged by liquid nitrogen completely, influences preservation effect.6. when strain is pulled out from liquid nitrogen container, due to the porous adsorptivity of sack, bag
Liquid nitrogen above son can not distribute in time, once drip to experimenter can bring about dangerous and injury with it.
For these reasons, some related practitioners devise the special dress with storage target biomaterial in liquid nitrogen container
It sets, such as Chinese utility model patent, No. CN204776751U discloses a kind of liquid nitrogen container hand basket, and one is connected in shadoof lower part
Stainless steel pail, pail inner hollow inside have 3 spaced demarcation strips that pail is partitioned into 3 straton spaces, empty per height
Between the door for being connected to the straton space is provided on side wall.Although the liquid nitrogen container hand basket of the structure can solve existing cloth to a certain extent
The problems of bag, but the liquid nitrogen container hand basket of the utility model there are problems that being inconvenient to pick and place cryovial.It is empty per straton
Between it is stacked on top of each other together, although every layer has side door, lateral to take object be inconvenient, adds the limited height of side door, makes to take
Letting cool frozen pipe seems more inconvenient, and side door be also easy to opens voluntarily (especially when mentioning from liquid nitrogen container, liquid nitrogen pressure
Power is larger, is easy to wash side door open), causing cryovial therein to be spilt can not take out to sink to tank bottom.And near side door
Region cannot store it is too full, otherwise be easy side door is pushed open.It is stored in addition, every layer of partition board is equipped with for preserving the pipe that pipe is inserted into
Bucket further increases the difficulty for picking and placeing and preserving pipe, and causes its space availability ratio also not high.
Therefore, it is necessary to be improved the prior art, a kind of novel liquid nitrogen container specimen storage device is provided.
