Abstract
The utility model discloses a porous plastic seal bag for liquid nitrogen frozen biological tissue which is a small tool and related to medical and pharmaceutical teaching and scientific researches, and belongs to common-use consumables in laboratories. The porous plastic seal bag for the liquid nitrogen frozen biological tissue is characterized in that three rows of small round holes with 1.2 mm phi spacing of 8mm are formed in a single face of the lower portion of the plastic seal bag, and a label hole which enables specimens in a liquid nitrogen transfer tank to be sequentially transferred to an ultra-low temperature freezer is formed in one side of the upper portion of a seal opening. The design of the porous plastic seal bag for the liquid nitrogen frozen biological tissue solves the problems that after the biological tissue is frozen by liquid nitrogen, tube bursting may occur and the biological tissue is not prone to be frozen rapidly and evenly, and therefore operation processes are more convenient and fast.
Description
Technical field:
The experiment consumable store of medical science, pharmacy teaching and scientific research.
Background technology:
In medical science, pharmaceutical test research, need the flesh tissue sample is put into the liquid nitrogen transfer tank, make and organize quick freezing.Present most experimental technique is to cut to put into freeze pipe rapidly behind the tissue or put into plastic closures bag sealing back freezing, and then deposits-80 degree ultra low temperature freezers in.The use of freeze pipe will note preventing freezing back booster.Also have in order to organize quick freezing, in filling the container of tissue, directly pour liquid nitrogen into, and then encapsulation immigration liquid nitrogen container, this can bring operation inconvenience and occur operate miss easily or bring pollution.Therefore improve the experimental technique operation link, help to overcome the error that produces because of operation.
Summary of the invention:
For overcome biological tissue through liquid nitrogen frozen may occur freezing after booster, be difficult for even freezing problem fast, the utility model provides the porose plastic sealed bag of a kind of liquid nitrogen frozen biological tissue, it is characterized in that at plastic closures bag bottom single face three row's spacings being arranged is 8 millimeters ￠ 1.2mm circular aperture, and be transferred to ultra low temperature freezer successively for ease of the sample with the liquid nitrogen transfer tank, one label hole is arranged sealing top one side, can hitch label.
This product is for biology research laboratory consumable store commonly used, when access biological tissue, directly tissue is put into this porose plastic sealed bag after, put into the liquid nitrogen transfer tank.When from the liquid nitrogen transfer tank, taking out tissue specimen, can move into ultra low temperature freezer fast as long as extract label.Can overlap a common plastics sealed bag outside as required.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the porose plastic sealed bag structural representation of this practical liquid nitrogen frozen biological tissue.
The number in the figure explanation:
1. porose plastic sealed bag 2. seals 3. label holes, 4. breather holes
The specific embodiment:
The porose plastic sealed bag of further setting forth the utility model liquid nitrogen frozen biological tissue below by using method arranges structure.When using, the line that at first will finish writing is in advance hung label and is enclosed within label hole (3), opens and seals (2), and the biological tissue that obtains is put into bag (1), will seal and seal, and speed is put into the liquid nitrogen transfer tank, outside label is stayed.
Claims (2)
1. the porose plastic sealed bag of liquid nitrogen frozen biological tissue is characterized in that it is 8 millimeters ￠ 1.2mm circular aperture (4) that plastic closures bag (1) bottom single face has three row's spacings.
2. the porose plastic sealed bag of liquid nitrogen frozen according to claim 1 biological tissue, porose plastic sealed bag (1) seals (2) top one side a label hole (3).
