Further, the non-ink area is a laser scale area formed by laser marking.

Further, still be provided with the sign region that is used for distinguishing article on the outside portion of body, the sign region is through moulding plastics formation.

Further, the centrifuging tube still includes the base, be provided with on the base and be used for placing the well kenozooecium of centrifuging tube, the cross section of base is trapezoidal.

Further, the bottom of body is provided with filtering screen, filtering screen's top is provided with the recess, be provided with on the bottom inner wall of body with the recess card is held in order will filtering screen fixed lug.

Further, the bottom of the filtering screen is in a conical structure.

The beneficial effects of the utility model reside in that: the calibration area is set to be a non-ink area, so that the centrifugal tube product is prevented from being polluted by ink printing, and the use of the centrifugal tube is influenced; and indirectly avoids the influence on the use caused by the physical or chemical reaction between the ink and the experimental reagent in the use process;

through being equipped with the base that is used for placing the centrifuging tube for the centrifuging tube is placed more portably in the use.

The above description is only an overview of the technical solution of the present invention, and in order to make the technical means of the present invention clearer and can be implemented according to the content of the description, the following detailed description is made with reference to the preferred embodiments of the present invention and accompanying drawings.

Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Please refer to fig. 1 to 3, the centrifuge tube in a preferred embodiment of the present invention includes a tube body 2 and a cover body 1 in threaded connection with the tube body 2, in this embodiment, the threaded connection is a conventional means, such as a general thread shape having a triangle, a rectangle or an arc, which is continuously or discontinuously arranged, and the general thread starts to tend to a smaller angle, and the outside tends to an angle which is greatly beneficial to the matching of the parts of the threaded connection, which is not described herein.

The outer side of the tube body 2 is provided with a scale area 21, and the scale area 21 is a non-ink area. In the present embodiment, the non-ink area 21 is a laser scale area 21 formed by laser marking. Laser marking is a marking method in which a workpiece is irradiated locally with high-energy-density laser to vaporize a surface layer material or to undergo a chemical reaction of color change, thereby leaving a permanent mark. The laser marking can print various characters, symbols, patterns and the like, and the size of the characters can be from millimeter to micron, which has special significance for the anti-counterfeiting of products. In the embodiment, the laser scale area 21 is formed in a laser marking manner to prevent the centrifugal tube product from being polluted by ink printing, so that the use of the centrifugal tube is influenced; and indirectly avoids the influence on the use caused by the physical or chemical reaction between the ink and the experimental reagent in the use process. Indeed, in other embodiments, the non-ink area 21 may also be a scale area 21 marked by other means, as long as the same purpose and effect can be achieved, and the non-ink area 21 is not specifically limited herein, depending on the actual situation. Still be provided with the sign region 24 that is used for the sign in order to distinguish article on the outside portion of body 2, sign region 24 is through moulding plastics formation, and this sign region 24 is for deckle edge in order to write or paste the label, forms comparatively convenient and fast through moulding plastics. Indeed, in other embodiments, the identification area 24 may be formed by other means, such as laser marking, and is not particularly limited herein, as the case may be. The identification area 24 has a rectangular structure, and indeed, in other embodiments, the identification area 24 may have other shapes, which are not specifically limited herein, depending on the actual situation. The outer side of the tube body 2 is also provided with a trademark area 25, which trademark area 25 coincides with the graduated area 21 and is also formed by laser marking to prevent contamination.

The centrifuge tube further comprises a base 3, the base 3 is provided with a hollow part 31 for placing the centrifuge tube, and the cross section of the base is trapezoidal. Indeed, in other embodiments, the cross section of the base may have other shapes, which are not limited to the specific shape according to the actual situation. Through being equipped with the base 3 that is used for placing the centrifuging tube for the centrifuging tube is placed more portably in the use.

The bottom of the pipe body 2 is provided with a filter screen 22, the top end of the filter screen 22 is provided with a groove (not shown), and the inner wall of the bottom of the pipe body 2 is provided with a projection 23 which is clamped with the groove to fix the filter screen 22. The bottom of the filtering screen 22 is of a conical structure so as to fit the bottom of the pipe body 2, and indeed, the bottom of the filtering screen 22 may be of other shapes, which is not specifically limited herein and is determined according to actual situations.

In summary, the following steps: the calibration area is set to be the non-ink area 21, so that the centrifugal tube product is prevented from being polluted by ink printing, and the use of the centrifugal tube is prevented from being influenced; and indirectly avoids the influence on the use caused by the physical or chemical reaction between the ink and the experimental reagent in the use process;

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
