Abstract
The utility model discloses the device of a kind of quick tissue abrasion sample, comprise foam box (4), be narrow-mouthed bottle (5) in foam box (4), the bottle mouth position of narrow-mouthed bottle (5) has fixing stopper (2), V-arrangement mill (3) is through the circular hole on fixing stopper (2) and lower end is placed in narrow-mouthed bottle (5), has grinding rod (1) in V-arrangement mill (3).Different tissue samples is positioned in different mills by the utility model, during experiment, opens fixing stopper (2) and in bottle, adds appropriate liquid nitrogen rapidly and accurately, grind after tightening rapidly.The utility model is simple and easy to make, convenient and practical; To grinding-material no requirement (NR), to grinding condition also no requirement (NR), can carry out whenever and wherever possible, milling time is short, effective, to the composition of organization material without destruction, can not have any impact to subsequent experimental, not only save time and human and material resources, the carrying out of testing effective can also be ensured.
Description
Technical field
The utility model relates to the structure of the device, particularly lapping device of a kind of quick tissue abrasion sample.
Background technology
Current, the many experiments in laboratory need to carry out the process such as grinding to experiment material, the Ginding process that laboratory is commonly used is mortar grinder method, namely directly grind, the method not only wastes time and energy, and some material of easily degrading is difficult to realize, the organization material of such as minority needs to grind on ice, even if but be placed on the requirement of grinding and being also difficult to reach experiment on ice.
Summary of the invention
The technical problems to be solved in the utility model is: for the defect of the deficiency of traditional mortar grinder and the upper of technology, provides a kind of simple, easy to operate, tissue sample lapping device that grinding effect is splendid.
The technical solution adopted in the utility model is: the device of a kind of quick tissue abrasion sample, comprise foam box, be narrow-mouthed bottle in foam box, the bottle mouth position of narrow-mouthed bottle has fixing stopper, V-arrangement mill is through the circular hole on fixing stopper and lower end is placed in narrow-mouthed bottle, has grinding rod in V-arrangement mill.Foam box can prevent the hand of the leakage frostbite grind away people of liquid nitrogen.
Circular hole aperture on fixing stopper is less than the maximum gauge of V-arrangement mill.Circular hole on fixing stopper can be managed or V-arrangement mill compact siro spinning technology with grinding, prevents gas leakage and convenient grinding.
The bottom of V-arrangement mill is below the bottleneck of narrow-mouthed bottle.V-type mill can partly go deep in thin mouth, contacts with the nitrogen of the inside the object reaching cooling.
Fixing stopper is stepped cylindrical shape, and narrow-mouthed bottle is plastic bottle, is converted by thin mouth plastic bottle.
Different tissue samples is positioned in V-arrangement mill, by the label paper number of finishing.In narrow-mouthed bottle, add liquid nitrogen, mill is positioned on fixing stopper rapidly and grinds.Experiment according to carrying out is learnt, the experiment material grinding effect obtained by the method is splendid, and substantially can not cause the degraded of sample composition, for follow-up experiment provides good experiment basis.Also save experimental period and human resources simultaneously, improve the efficiency of experiment.
This device selects common thin mouth plastic bottle to be material, the circular aperture that one, brill is identical with V-arrangement mill diameter on the fixing stopper of narrow-mouthed bottle, get out experiment material on pretreatment, protective gloves is brought to be poured into fast in plastic bottle by liquid nitrogen, tighten fixing stopper and lapping device be placed on rapidly in fixing stopper circular aperture, with grinding rod rapid tissue abrasion sample.
Compared with conventional method, in quick tissue abrasion of the present utility model sampling device, experiment material used is the common thin mouth plastic bottle in laboratory and common experiment reagent liquid nitrogen, there is production cost low, make simple, fast easy to use, the features such as grinding effect is good, this simple and effective method and apparatus can bring great convenience for laboratory science research.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of fixing stopper.
Corresponding being labeled as in figure: grinding rod 1 fixes stopper 2 V-type mill 3 foam box 4 narrow-mouthed bottle bottle 5.
Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with embodiment, but be not restricted to following content.
As depicted in figs. 1 and 2, the device of a kind of quick tissue abrasion sample, this device is primarily of grinding rod 1, fixing stopper 2, V-type mill 3, foam box 4 and narrow-mouthed bottle 5 five part composition.Be narrow-mouthed bottle 5 in foam box 4, the bottle mouth position of narrow-mouthed bottle 5 has fixing stopper 2, and V-arrangement mill 3 is through the circular hole on fixing stopper 2 and lower end is placed in narrow-mouthed bottle 5, has grinding rod 1 in V-arrangement mill 3.Circular hole aperture on fixing stopper 2 is less than the maximum gauge of V-arrangement mill 3.The bottom of V-arrangement mill 3 is below the bottleneck of narrow-mouthed bottle 5.Fixing stopper 2 is stepped cylindrical shape, and narrow-mouthed bottle 5 is plastic bottle.
The thin mouth plastic bottle that the device of quick tissue abrasion sample selects laboratory common is making material, the circular aperture that one, brill is identical with V-arrangement mill 3 diameter on the fixing stopper 2 of narrow-mouthed bottle 5, get out experiment material on pretreatment, protective gloves is brought to be poured into fast in plastic bottle by liquid nitrogen, place fixing stopper 2 and V-arrangement mill 3 be placed on rapidly in the circular port of fixing stopper 2, upper narrow-mouthed bottle 5 is covered with foam box 4, can prevent liquid nitrogen from spreading the hand of frostbite operator, with grinding rod 1 tissue abrasion's sample rapidly, be convenient to continue subsequent experimental.Compared with Conventional milling methods, it is low that this method and device have production cost, and make simple, fast easy to use, the features such as grinding effect is good, can meet the grinding requirement of kinds of experiments material.Rapidly fixing stopper 2 is tightened after filling it up with liquid nitrogen in described thin mouth plastic bottle, and V-arrangement mill 3 or centrifuge tube are positioned in the circular aperture on fixing stopper 2, the centrifuge tube of different tissue samples or V-arrangement mill 3 label paper or marking pen number sorting are housed.Utilizing liquid nitrogen cryogenics quick-frozen and vaporizing to absorb heat in a large number when the circular aperture that bottleneck is fixed on stopper 2 is overflowed makes tissue sample become very easily polished pulverizing, and utilize liquid nitrogen grinding, tissue sample can not only be allowed hardening, and fragility increase is easy to grind; The not easily destroyed or degraded of various structural constituent can be made again, as DNA or RNA etc., substantially increase efficiency and the success rate of experiment.
Know through many experiments, the experiment material obtained by the method can not cause degraded and the destruction of sample composition substantially, and grinding effect is splendid, for follow-up experiment provides good experiment basis.Also save time and human and material resources simultaneously, improve the efficiency of experiment.
