Interconnected centrifuge tube

Technical Field

The utility model relates to a centrifuging tube technical field, concretely relates to interconnection formula centrifuging tube.

Background

In the field of biological science, especially in the research field of biochemistry and molecular biology, centrifugal tubes and centrifuges matched for solid-liquid separation have been widely used, for example, separation and preparation of various biological samples, and extraction of DNA, RNA, protein and the like can be realized through the matched centrifuges and centrifugal tubes. Specifically, the experimenter holds the biological sample suspension in a centrifuge tube, and the centrifuge tube settles suspended fine particles (such as organelles and precipitates of biological macromolecules) at a certain speed under the action of centrifugal force generated by high-speed rotation of the centrifuge tube, so that the particles are separated from the solution.

In the conventional experiment process, often need label hundreds of centrifuging tubes simultaneously, and present conventional centrifuging tube all exists alone, and the experimenter needs label one by one according to the sample size for preorder preparation work such as the label of centrifuging tube, range consumes a large amount of time, reduces experimenter's work efficiency. And the centrifugal tube for molecular experiment is generally smaller, and the problems of the centrifugal tube loss, the staggered arrangement and the like easily occur in the using process, so that the experimental result is influenced or the experiment is replenished again, and the experimental process is slowed down. Meanwhile, the experimenter usually writes the serial numbers on the tube wall and the cover of the centrifuge tube, and in the experimental process, the used organic solvent easily erases the serial numbers due to volatilization or seepage, so that the serial numbers are difficult to distinguish again, and the experimental results are lost in different degrees. In addition, the condition that the serial number writing is worn and blurred can also occur to the centrifuging tube that is equipped with the sample in long-term storage process to the follow-up of experiment is influenced.

The prior art CN207042513U discloses a row-type centrifuge tube set, which includes a plurality of centrifuge tubes arranged in a row-by-row manner, wherein the centrifuge tube includes a tube body, an inner cap, an outer cap and a telescopic connection device; the inner cover is fixedly connected with the tube body and can seal the tube body; the outer cover is sleeved on the outer layer of the inner cover at the upper part of the pipe body; the telescopic connection device is fixedly arranged on the tube body, and the plurality of centrifuge tubes are connected through the telescopic connection device, so that the distance between the centrifuge tubes can be adjusted. The utility model adopts the telescopic connecting device to connect a plurality of centrifuge tubes in groups in a row, is convenient and saves space when in use, and the numbering and arrangement between centrifuge tubes are clear and simple, thereby effectively solving the problems of easy loss, staggered arrangement and the like when a large number of centrifuge tubes are used; this flexible connecting device can guarantee simultaneously that this centrifuging tube no matter be on the centrifuge tube board or in centrifuge operation process, can both be nimble freely, be difficult for receiving the influence of tube hole distance. However, the prior art still has the following problems:

1) The inner cover arranged in the prior art is mainly used for labeling and needs manual labeling, so that a lot of time is still consumed for preparing hundreds of labeled centrifuge tubes; the label marked on the inner cover is still easy to dissolve and blur due to contact with an organic solvent for experiments, and the problems that the label consumes long time and is easy to blur cannot be really solved;

2) The design of a centrifugal tube in the prior art is too complex, the centrifugal tube is different from the conventional centrifugal tube in the market and only has one outer cover, and the centrifugal tube is provided with two layers of cover bodies, namely an inner cover and an outer cover; however, in the actual experiment process, samples are often added and sampled into the centrifuge tube, and the speed of opening and closing the cover is reduced by the two layers of cover bodies, so that the time required by adding the samples into each centrifuge tube is increased, and the experiment efficiency is obviously reduced;

3) The centrifuge tubes in the prior art are only single-row centrifuge tubes, the centrifuge tubes cannot be connected with each other according to actual conditions, and simultaneously, the selectable collocation modes are limited due to the fact that the arrangement modes of the centrifugal holes in the rotors of the centrifuge machines of different types are greatly different.
