Problems solved by technology

The use of this centrifuge tube in some cases will bring very inconvenient content, such as when there are few solid phase substances, it is often difficult or even impossible to obtain the separator from the pouring liquid end; in addition, sometimes Because the bottom area of ​​some centrifuge tube conical tubes is usually too large, solid phase substances are not easy to be concentrated

Embodiment 1

[0019] The method for separating solid-phase substances in the mixed liquid phase using the above-mentioned syringe-type centrifuge tube device specifically includes the following steps:

[0020] In step 1, the lower end 3 of the straight pipe is assembled with the upper end 4 of the tapered pipe and kept in a sealed connection.

[0021] Step 2, pour the mixed liquid phase to be separated into the straight pipe from the upper end 1 thereof.

[0022] In step 3, the tube is centrifuged on a machine to separate solid and liquid phases.

[0023] Step 4, take out the tube from the centrifuge, pour out from the upper end 1 of the straight tube or use a straw to suck out the upper part of the liquid phase separated in the tube.

[0024] Step 5, remove the reinforced protective tube 10 that is placed on the liquid outlet straight pipe 6, and apply a transverse shear force to the V-shaped incision 7, so that it breaks at the upper plane of the inner chamber partition layer of the liqu...

Embodiment 2

[0027] Such as figure 2 As shown, a syringe-shaped centrifuge tube device for conveniently obtaining centrifuged substances, including a straight tube upper end 1, a straight tube 2, a tapered tube 5, a liquid outlet straight tube 6, a liquid outlet straight tube lower end 8, and an outer wall V of the liquid outlet straight tube Type incision 7 and liquid outlet straight pipe inner cavity partition layer 9, reinforced protective tube 10; when in use, select a suitable liquid outlet straight pipe inner cavity from 1 to 10 mm according to the size of the sample volume of the mixed liquid phase and the amount of solid phase contained in it The diameter of the cavity; the reinforced protective tube 10 is directly placed on the liquid outlet straight tube 6 to play a strengthening role, so as to ensure that the V-shaped incision is not affected by external force;

[0028] The method for separating solid-phase substances in the mixed liquid phase using the above-mentioned syringe-...

Abstract

The invention relates to an injector-shaped centrifuge tube device convenient for obtaining centrifugal separation products. The injector-shaped centrifuge tube device is characterized in that the injector-shaped centrifuge tube is composed of a straight tube on the upper portion, a conical tube on the lower portion and a liquid outlet straight tube at the bottom, wherein a partition layer is arranged at the edge, close to a bottom opening, of the lower end of an inner cavity of the liquid outlet straight tube, a non-cut-off V-shaped circumferential notch is formed in the level position, outside the liquid outlet straight tube, of the upper plane of the partition layer, and a reinforcing protective tube is arranged outside the liquid outlet straight tube in a sleeving manner. According tothe method and the injector-shaped centrifuge tube device, the operation is easy to achieve, the centrifugal separation products can be easily collected, and the method for obtaining the centrifugal separation products is greatly simplified.

Description

technical field [0001] The invention relates to a device for obtaining sediment after centrifugation, in particular to a device for obtaining micro-sediment. Background technique [0002] Centrifugation is a general method for obtaining separated solid phase substances from mixed liquid phases. The centrifuge tubes currently used in centrifugation are usually centrifuge tubes with a tapered bottom, and the method of taking out the separated solid phase material is usually obtained from the pouring liquid end of the centrifuge tube. The use of this centrifuge tube in some cases will bring very inconvenient content, such as when there are few solid phase substances, it is often difficult or even impossible to obtain the separator from the pouring liquid end; in addition, sometimes Since the bottom area of ​​some centrifuge tube conical tubes is usually too large, solid phase substances are not easily concentrated. All of these will affect the acquisition, detection, analysis...
