Description

A kind of cell culture centrifuge tube

Technical field

The utility model is related to experiment appliance field, more particularly to a kind of cell culture centrifuge tube.

Background technology

Centrifuge is medicine, chemical industry, the commonly used laboratory apparatus of biological study, and centrifugation technique is mainly used in various samples Separate and prepare, sample suspension is positioned in centrifuge tube, in the case where high speed rotates, due to huge centrifugal action, suspend Molecule separated with solution with certain velocity sedimentation.Centrifuge tube is the requisite structure member of centrifugation technique, is adopted The centrifuge tube of different size and pattern is up to different experiment purposes.Conical centrifuge tube, to trace suspension thing Jing after centrifugation, The thicker beds of precipitation can be accumulated in bottom, be easy to observe color and luster and crystal shape；Round bottom centrifuge tube, is adapted to big molten of capacity Liquid centrifugation layering is used.

The round bottom centrifuge of laboratory configuration is not available for conical centrifuge tube to use, and can otherwise cause the damage of machine, if increasing Plus purchase machine then increases cost, so the conical centrifuge tube that design is applicable to round bottom centrifuge has practical value.

Utility model content

The purpose of this utility model is to provide a kind of cell culture centrifuge tube, solves existing conical centrifuge tube and does not apply to In the problem of round bottom centrifuge.

For achieving the above object, above-mentioned technique effect is reached, the utility model solves above-mentioned asking by the following technical programs Topic：

A kind of cell culture centrifuge tube, including body and lid, the body outer bottom is circular arc type structure, inner bottom surface For pyramid type structure.External structure is identical with existing standard centrifugation tube shape, centrifuge tube is brought into close contact with tube seat, is avoided that pipe Body in high-speed rotation because of unbalance stress caused by damage.Cell research belongs to micro research, is often applied to sharp bottom centrifugation Tubular body is set to circular cone bottom surface, can be met the requirement of cell research in the case of using round bottom centrifuge by pipe.

Used as a kind of above-mentioned improvement of cell culture centrifuge tube of the utility model, the lid is double-deck annuli arrangement, Internal layer ring taps is fitted with inboard wall of tube body, and outer layer ring cowling is fitted with tube wall.When covering lid, the embedded internal layer ring taps of body with it is outer In groove between layer ring cowling.The common function of lid is supported centrifuge tube, prevents which from deforming for preventing sample from leaking and volatilizing.It is single The centrifuge tube of outer cover or internal stopper is solely set, and body may not fitted with lid because the reasons such as temperature produce deformation, double-deck Circulating type lid can more preferable closed tube, prevent its deformation.

Used as a kind of above-mentioned improvement of cell culture centrifuge tube of the utility model, the body top arranges convex annular Line, annular burr are engaged with outer layer ring cowling.The contact area that annular burr can increase body and lid is set, is pressed between increase face Power, increases the friction between body and lid, it is to avoid in experimentation, lid is departed from body.

The beneficial effects of the utility model are：

The utility model by conventional round bottom centrifuge tube inner bottom surface is set to pyramid type structure, make body possess round bottom from Heart pipe external structure and conical centrifuge tube built-in function, make conical centrifuge tube be applicable to round bottom centrifuge.Meanwhile, lid is set Be set to double-deck annuli arrangement, can more preferable closed tube, prevent its deformation.The utility model can solve existing conical centrifuge tube not Suitable for the problem of round bottom centrifuge.

Description of the drawings

Fig. 1 is a kind of cell culture centrifuge tube schematic diagram.

Figure number is identified：10th, body, 11, annular burr, 20, lid, 21, internal layer ring taps, 22, outer layer ring cowling.

Specific embodiment

The utility model is described in further detail with reference to embodiments, but the utility model is not limited to following enforcement Example.

A kind of cell culture centrifuge tube described in this example, as shown in Figure 1, including body 10 and lid 20, the pipe 10 outer bottom of body is circular arc type structure, and inner bottom surface is pyramid type structure.Tube core top is column structure, and bottom is tied for inverted cone Structure, starts at tube core bottom about 2/3, and the sharp bottom for taper is gradually reduced, and the thickness of body 10 changes from small to big.

As shown in Figure 1, the lid 20 using double-deck annuli arrangement, fitted with 10 inwall of body, outward by internal layer ring taps 21 Layer ring cowling 22 is fitted with 10 outer wall of body.Body 10 is embedded in the groove between internal layer ring taps 21 and outer layer ring cowling 22, to body 10 There is certain supporting role, can prevent body 10 from deforming.10 top of body is provided with a ring shape burr 11, annular burr 11 with Outer layer ring cowling 22 engages, it is possible to increase the squeezing action to outer layer ring cowling 22, prevents lid 20 from departing from.

The operation principle of the present embodiment is：

Lid is opened, cell culture medium is put in pipe, lid is covered, centrifuge tube is put in the sleeve pipe of round bottom centrifuge (test as done single with the centrifuge of a double sleeve pipe, it is necessary to load the water of same volume in another centrifuge tube, to keep flat Weighing apparatus), start centrifuge, centrifuge tube horizontal direction is rotated at high speed, produce powerful centrifugal force, make suspension in pipe from In the presence of mental and physical efforts, it is deposited at the bottom circular cone of pipe, reaches the purpose of multi_layer extraction.Can be in bottom using conical bottom centrifuge tube The thicker beds of precipitation are accumulated into, are easy to observe and are extracted.
