Abstract
The invention discloses a test tube frame capable of clamping a test tube when being inverted downward manually or by an instrument. The test tube frame consists of three parts, namely a top layer frame, a flexible friction sheet and a base frame which form a hole slot array after being assembled together; holes or hole slots of the three parts at the same positions form test tube clamping hole slots; the diameter of each hole of the flexible friction sheet is less than the diameter of the outer wall of the loaded test tube; sufficient friction can be generated to clamp the test tube after the test tube is inserted. By adopting the test tube frame, the working efficiency of experimental steps, such as centrifugal sediment cleaning, can be improved greatly.
Description
Technical field
The present invention relates to a kind of rack for test tube, especially relating to a kind of rack for test tube that still can clamp loading test tube when being inverted.
Background technology
Micro centrifugal pipe is conventional in many laboratories does reaction tube or memotron, especially biology or Molecular Biology Lab.In laboratory, many reactions or cleaning step all can have topples over supernatant one step.Topple over the supernatant in micro centrifugal pipe, test tube is taken out from rack for test tube one by one, turn after pouring out supernatant downward, place back rack for test tube.When fill in shelf a lot of or fill test tube time, this process is just very time-consuming.Meanwhile, if test tube does not have correct label can mix up sample number program and the danger of cross pollution occurs.Therefore, need the more efficient step of one or instrument, operate centrifuge, topple over supernatant, cleaning or dry sample pellet of purifying.
In chemistry, biochemical, molecular biology or Cell Biology Experiment room, many reactions and process all relate to centrifugal, precipitation, are separated solid-liquid, cleaning or drying steps.Under lab, micro centrifugal pipe is the most frequently used does reative cell or storage vessel.In general, micro centrifugal pipe is placed on pipe support, so that take and store.When operating procedure require test tube to be inverted pour out liquid or supernatant and drying precipitated cake time, test tube is put in order to origin-location and just becomes and require great effort very much after liquid or supernatant in each test tube on shelf are poured out.The test tube be placed in traditional rack for test tube turns an angle at rack for test tube, turn towards upper and lower lower movement or when being hit, can be easy to drop out.Mix up sample like this and cause cross pollution and the danger of losing precious sample.This reduces sample disposition mistake in the urgent need to a kind of new process or instrument one and increases work efficiency.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of rack for test tube, though completely down time, it also can catch test tube firmly.
The present invention solves the problems of the technologies described above adopted technical scheme:
A kind of rack for test tube, is made up of three parts: one with the abase frame inserting cuvette groove array; One with the flexible friction sheet of perforate being same as cuvette groove array, its opening diameter is less than abase frame cuvette groove internal diameter; A top layer frame with the perforate of identical cuvette groove array.Flexible friction sheet clamps and is fixed between top layer frame and abase frame.Three parts are assembled by hinge, latch or snap close etc.When test tube height is suitable, diameter is less than abase frame and top layer frame notch diameter is still greater than flexible friction sheet test tube notch diameter, test tube is placed in shelf slotted eye and will be locked, and can not rotate and move up and down.
In this patent is preferentially implemented: abase frame adopts solid material, the half or slightly many that the degree of depth of its hole slot array is selected type test tube height, as microcentrifugal tube, PCR test tube, storage tube, test tube etc.Further in preferential enforcement: abase frame adopts plastics, and the shape of slotted eye is similar or almost identical with the outer shape of selected type test tube, to limit the movement of test tube in shelf.
In this patent is preferentially implemented: flexible friction sheet adopts block to adopt to have the elastomeric material of sufficient intensity and durability, its hole slot array identical with abase frame slotted eye array, opening diameter is slightly less than the diameter of abase frame slotted eye.Further preferentially to implement: abase frame adopts rubber or silica gel plastics, be preferably anticorrosive and the rubber of solvent or silica gel plastics.
In this patent is preferentially implemented: top layer frame adopts solid material, its through-hole array identical with abase frame hole slot array, thickness can provide sufficient intensity and stay enough highly to be convenient to test tube placement on the top of the shelf or taking-up.Further in preferential enforcement: top layer frame adopts plastics, is preferably transparent plastic.
Compared with prior art, the invention has the advantages that: though this rack for test tube completely down time, also can catch test tube firmly.

Fig. 1 is schematic three dimensional views of the present invention;
Fig. 2 is the diagram of the perforate of flexible friction sheet in the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
According to patent of the present invention, announce a rack for test tube at this.This rack for test tube is made up of three parts: an abase frame, a flexible friction sheet, a top layer frame.Three parts are connected by screw thread, hinge or size adaptor line style.Abase frame can be the rack for test tube of concrete certain hole slot degree of depth, and the degree of depth is about the half of corresponding test tube height.
In FIG, rack for test tube 10 is illustrated and is illustrated, and comprises abase frame 12, flexible friction sheet 14 and top layer frame 16.Abase frame 12 is generally smooth rectangular block, its upper surface 18 be according to institute hold slotted eye array 20(rack for test tube as shown in Fig. 1 that test tube has certain depth, 80 accommodation 1.5 milliliters of micro centrifugal pipe slotted eyes, 5 row 16 arrange).The existing taper of slotted eye 20 inwall is to hold and to limit the test tube of various outer diameter.Slotted eye 20 opening is comparatively large, to hold the tongue 24 in the perforate 22 of test tube and flexible friction sheet 14.There is a pin array 26 corner on surface 18, through flexible friction sheet 14 pin hole array 28 and compactly insert the pin hole array 30 of top layer frame 16.
Flexible friction sheet 14 adopts elastomeric material, such as, have rubber and the silica gel plastics of higher coefficient of friction, can provide enough frictional force with when test tube wall contacts.Cushion 14 has an opening array 22 identical with the slotted eye array 20 on pedestal 12, perforate has bent ligule figure 24.The thickness optimizing friction pad 14 makes it have sufficient intensity and produces enough frictional force, keeps test tube can not rotate or vertically movement.
Top layer frame 16 is rectangular blocks of plastics and so on solid material.Block has an opening array 32, it is identical with the slotted eye array 20 of abase frame 12, and opening diameter is slightly larger than test tube maximum outside diameter.
Flexible friction sheet 14 is clipped between top layer frame 16 and abase frame 12.Three incorporating aspects together, by the pin array 26 in abase frame 12 through the pin hole array 22 of flexible friction sheet 14 and the pin hole array 30 closely inserted on top layer frame 16.
In Fig. 2, illustrate the flexible friction sheet 12 that has pin hole array 28 and opening array 22, perforate is with ligule figure 24.
The system of showing here can according to place difformity and size test tube and design.Describe patent illustrative of the present invention preferentially to implement, be familiar with this technology it will be noted that issue here be only demonstration, any replacement, adaptive and change all in this patent coverage.Correspondingly, this patent is not limited to the particular implementation shown herein.
