Description
Technical Field
The utility model relates to a EP freezes deposits tube sheet.
Background
In traditional plastics EP tube sheet, because the material restriction of itself, can make sample temperature rise rapidly in directly putting into the room temperature pipe support with the EP pipe that the low temperature cryopreserved was equipped with the sample, to long-time experimental operation, sample holding time overlength will probably cause the degradation to influence the experimental result and influence the use of next sample. The existing treatment method is to put a proper amount of crushed ice into a foam box and then insert an EP tube into the crushed ice, so that the frozen storage can be carried out for a certain time. However, this method has several disadvantages: 1. the preparation time is too long, and a laboratory must be provided with an ice crusher; 2. because gaps are formed among the crushed ice, the temperature of each position of the sample is different when the sample is stored, and the phenomenon is more obvious particularly when an ice bag is used; 3. the carrying is very inconvenient; 4. during the experimental procedure, crushed ice may inadvertently fall into the EP tube and affect the sample.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the shortcoming that exists among the present background art, provide a EP cryopreserved tube sheet, including the tube sheet body, the inner chamber of tube sheet body is hollow structure, tube sheet body upper surface is opened there are a plurality of recesses that sink in, the both ends rigid coupling of tube sheet body has the handle, the lower surface of tube sheet body is opened there is the water injection hole, be equipped with the sealed lid of adaptation on the water injection hole, the intracavity is through the water injection hole injection cryopreserved liquid.
Furthermore, the tube plate body is made of stainless steel.
Further, the thickness between the inner wall and the outer wall of the groove is the same and is less than 3 mm.
Furthermore, the tube plate body is made of polyethylene.
Furthermore, the injection amount of the freezing liquid is smaller than the size of the inner cavity, and the freezing liquid adopts water-absorbent resin of high molecular polymer.
Further, the size of the groove is 0.2, 1.5, 5, 10, 20, 30 and 50ml for placing the EP tube according to requirements.
By adopting the technical scheme, the method has the following beneficial effects:
the utility model discloses holistic simple structure, the practicality, low cost, convenient to carry has solved because the space of garrulous ice makes EP pipe contact garrulous ice influence EP pipe temperature not of uniform size, can be fit for the quantization production, and the EP pipe that exists in the low temperature refrigerator is taken promptly and is used and need not to prepare, convenient to carry to can satisfy the cryopreserving of certain time and prevent that EP manages in the sample degradation, reduce experimental error.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the bottom structure of the present invention;
in the figure: 1-a tube plate body; 2-inner cavity; 3-water injection hole; 4-a handle; 5-groove.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Example 1: an EP cryopreserved tube plate as shown in figures 1 to 2 comprises a tube plate body 1, wherein an inner cavity 2 of the tube plate body 1 is of a hollow structure, a plurality of recessed grooves 5 are formed in the upper surface of the tube plate body 1, handles 4 are fixedly connected to two ends of the tube plate body 1, a water injection hole 3 is formed in the lower surface of the tube plate body 1, a sealing cover matched with the water injection hole 3 is arranged on the water injection hole 3, and cryopreserved liquid is injected into the inner cavity 2 through the water injection hole 3.
The tube plate body 1 is made of stainless steel.
The thickness between the inner wall and the outer wall of the groove 5 is the same and is less than 3 mm.
The tube plate body 1 is made of polyethylene.
The injection amount of the freezing liquid is less than the size of the inner cavity 2, and the freezing liquid adopts water-absorbent resin of high molecular polymer.
The size of the groove 5 is 0.2, 1.5, 5, 10, 20, 30 and 50ml for placing the EP tube according to requirements.
Example 2: the utility model provides a EP freezes deposits tube sheet, includes tube sheet body 1, inner chamber 2 of tube sheet body 1 is hollow structure, open tube sheet body 1 upper surface has a plurality of recesses 5 that sink in, tube sheet body 1's both ends rigid coupling has handle 4, open tube sheet body 1's lower surface has water injection hole 3, be equipped with the sealed lid of adaptation on the water injection hole 3, the freezing liquid of depositing is poured into through water injection hole 3 in the inner chamber 2.
The thickness between the inner wall and the outer wall of the groove 5 is the same and is less than 3 mm.
The tube plate body 1 is made of polyethylene.
The injection amount of the freezing liquid is less than the size of the inner cavity 2, and the freezing liquid adopts water-absorbent resin of high molecular polymer.
The size of the groove 5 is 0.2, 1.5, 5, 10, 20, 30 and 50ml for placing the EP tube according to requirements.
The EP pipe that will place in the recess is taken out from the refrigerator through the handle at both ends, the thickness between the inner wall of recess 5 and the outer wall reduces along with thickness, the effect of freezing is just better, the water injection hole 3 that leaves is for preventing that the freezing fluid from making cost tube sheet body 1 warp because freezing back volume grow, it is that to leave certain expansion space for the freezing fluid to freeze the inner chamber 2 that can not fill inner chamber 2, the EP board is placed in recess 5, a tube sheet body 1 can be opened a plurality of different sizes recess 5 or the same recess 5 and place different EP cast number, but need notice, the EP pipe capacity is big more, the effect of freezing is just weaker.
The utility model discloses holistic simple structure, the practicality, low cost, convenient to carry has solved because the space of garrulous ice makes EP pipe contact garrulous ice influence EP pipe temperature not of uniform size, can be fit for the quantization production, and the EP pipe that exists in the low temperature refrigerator is taken promptly and is used and need not to prepare, convenient to carry to can satisfy the cryopreserving of certain time and prevent that EP manages in the sample degradation, reduce experimental error.
Having described the basic principles and essential features of the invention, it will be understood by those skilled in the art that the present invention is not limited by the embodiments described above, which are merely illustrative of the principles of the invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed, and which are defined by the appended claims and their equivalents.
