Abstract
The utility model discloses an auxiliary fixing device suitable for extracting a small amount of RNA samples. The device is characterized by comprising an upper laminated plate, a lower laminated plate, a solid cuboid and four support upright posts, wherein the solid cuboid is arranged on the upper laminated plate and positioned at one side of the upper laminated plate; the upper surface of the solid cuboid is higher by 15-20mm than the upper laminated plate; centrifuge tube placement holes are correspondingly formed in the upper laminated plate and the lower laminated plate; a centrifuge tube cover placement groove is formed in the cuboid upper surface; centrifuge tube cover fixing circular rings are fixed at the two sides of the placement groove by virtue of two elastic ropes connected to the circular ring. The auxiliary fixing device has the advantages that a centrifuge tube is placed into the placement hole and can be fixed well by virtue of the device; a grinding rod is held with one hand while the fixing device is held with the other hand to grind when being used so that grinding states of samples can be conveniently observed anytime; therefore, the device is convenient to operate, the time is saved, the direct contact with the centrifuge tube filled with the liquid nitrogen can be avoided, and the device is convenient to use.
Description
Technical field
The utility model relates to a kind of auxiliary fixing device that a small amount of sample rna extracts that is suitable for, be a kind of can be in centrifuge tube the secondary station of a small amount of and rare sample of milling and extracting tobacco, also can be for the extraction of a small amount of sample of other plant.
Background technology
In laboratory, it is an operation of often using that liquid nitrogen grinding is extracted RNA at present.Conventional method is that tissue is put into mortar liquid nitrogen grinding at present, but for those a small amount of vegetable materials that maybe should not obtain as: (Henbane seed particle size is less for the seed of tobacco, approximately 11500 every gram), the tissue such as flower pesticide, filigree, can directly in the centrifuge tube of 1.5 ml, use liquid nitrogen grinding, but in the process of grinding, centrifuge tube easily shakes; Centrifuge tube is less in addition, after adding liquid nitrogen, temperature is very low, with hand steered be not very convenient, can cause grinding rod along with centrifuge tube skids, not only reduce the grinding rate of sample, also can cause and want constantly in centrifuge tube, to add liquid nitrogen, increase the usage quantity of liquid nitrogen, in addition sample is exposed in air for a long time, and the RNA of sample is increased by the probability of RNA enzyme liberating, and this RNA extraction work thereafter of also giving brings many inconvenience and unnecessary loss.
Utility model content
A kind of auxiliary fixing device that is suitable for a small amount of sample rna extraction that the purpose of this utility model provides for above-mentioned all situations just, utilize this device centrifuge tube better can be fixed, both convenient operation, save time, avoid again the directly centrifuge tube of contact dress liquid nitrogen, and use very convenient.
The purpose of this utility model is by the following technical programs: a kind of auxiliary fixing device that is suitable for a small amount of sample rna extraction, comprise top plate, lower plywood, be arranged on top plate solid rectangular parallelepiped and be arranged on, four support posts between lower plywood form, solid rectangular parallelepiped is positioned at a side of top plate, solid rectangular parallelepiped upper surface is higher than top plate 15-20mm, upper, on lower plywood, correspondence offers centrifuge tube putting hole, solid rectangular parallelepiped upper surface offers centrifuge tube lid and places groove, centrifuge tube lid clamping rings is fixed on the both sides of placing groove by two stretch cords that are connected on this annulus.
On upper and lower laminate, correspondence offers three centrifuge tube putting holes.
The utility model has the advantage of: centrifuge tube is placed in putting hole, this device can be better fixing by centrifuge tube, during use, one hand-held grinding rod is being controlled on the other hand stationary installation and is being ground fast, and can observe easily at any time the grinding state of sample, both convenient operation, save time, save the usage quantity of liquid nitrogen, avoid again the directly centrifuge tube of contact dress liquid nitrogen, and use very convenient.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1: a kind of auxiliary fixing device that is suitable for a small amount of sample rna extraction, comprise top plate 1, lower plywood 2, be arranged on the solid rectangular parallelepiped 6 on top plate and be arranged on, four support posts 5 between lower plywood form (support post is positioned at four angles), solid rectangular parallelepiped 6 is positioned at a side of top plate 1, its upper surface is higher than top plate 15-20mm, upper, on lower plywood, correspondence offers the aperture that three putting hole apertures on centrifuge tube putting hole 3(top plate are greater than lower plywood), rectangular parallelepiped upper surface offers centrifuge tube lid and places groove 7, centrifuge tube lid clamping rings 9 is fixed on the both sides of placing groove 7 by two stretch cords 10 that are connected on this annulus.
During use: centrifuge tube 4 is placed in the centrifuge tube putting hole 3 of upper and lower laminate, opens in the groove 7 that centrifuge tube lid 8 is placed on solid rectangular parallelepiped and put, utilize stretch cord 9 to fix with annulus 9.Install after centrifuge tube 4, with regard to controlling on the other hand centrifuge tube shelf (being auxiliary fixing device) with grinding rod on the other hand, grind; This device can be good at fixedly centrifuge tube, and use simple, flexible operation, and can effectively avoid grinding the problem that centrifuge tube skids in a small amount of sample in centrifuge tube.
The above; for better case study on implementation of the present utility model; not the utility model is done to any restriction, the structural changes of every any modification of being made with the utility model technical spirit, change and equivalence, all still belongs to the protection domain of technical solutions of the utility model.
Claims (2)
1. one kind is applicable to the auxiliary fixing device that a small amount of sample rna extracts, it is characterized in that: comprise top plate, lower plywood, be arranged on the solid rectangular parallelepiped on top plate and be arranged on, four support posts between lower plywood form, solid rectangular parallelepiped is positioned at a side of top plate, solid rectangular parallelepiped upper surface is higher than top plate 15-20mm, upper, on lower plywood, correspondence offers centrifuge tube putting hole, solid rectangular parallelepiped upper surface offers centrifuge tube lid and places groove, centrifuge tube lid clamping rings is fixed on the both sides of placing groove by two stretch cords that are connected on this annulus.
