Detailed Description

The conception, the specific structure and the technical effects of the present invention will be clearly and completely described in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the schemes and the effects of the present invention. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The same reference numbers will be used throughout the drawings to refer to the same or like parts.

It should be noted that, unless otherwise specified, when a feature is referred to as being "fixed" or "connected" to another feature, it may be directly fixed or connected to the other feature or indirectly fixed or connected to the other feature. Further, the description of the upper, lower, left, right, etc. used in the present invention is only with respect to the positional relationship of the respective components of the present invention with respect to each other in the drawings.

Referring to fig. 1 to 4, a centrifuging tube, including body 1 and tube cap 2, be equipped with lumen 11 in the

body

1, 11 one end of lumen forms mouth of pipe 12, and the other end is

shutoff end

13, 2 detachably of tube cap fix mouth of pipe 12 and will mouth of pipe 12 is sealed, and sealed back whole lumen 11 is isolated with external, can avoid external material to get into and cause the influence in 11 to the lumen 11 in the lumen 11. Wherein, the cross-sectional shape of the lumen 11 from the orifice 12 to the occlusion end 13 is a polygon, such as a triangle, a quadrangle, a pentagon, etc. Each limit of polygon all is the line segment, and is straight, consequently, the pipe wall of corresponding lumen 11 is the plane, because active cell is at the best of planar aerobic respiration effect of cultivation in-process, consequently adopts this centrifuging tube to carry out cell culture to be favorable to improving the success rate of cultivateing, and this centrifuging tube is applicable in cell culture. Wherein the cross section is a cross section perpendicular to the length direction of the tube body.

The existing centrifuge tubes are inconvenient to inoculate only by detaching the tube covers 2 when inoculating. Therefore, the utility model makes the following improvements: referring to fig. 1 and 2, a puncture hole 21 is formed in the tube cap 2, an elastic plug 22 is arranged in the puncture hole 21, and a needle tube can penetrate the elastic plug 22 through the puncture hole 21 to inoculate a sample into the tube cavity 11, so that the tube cap 2 does not need to be detached during inoculation, and the tube cap is more convenient to use.
