Abstract
The utility model discloses a kind of disposal type trace biological tissue milling tool.This utility model comprises centrifuge tube and grinding rod; Grinding rod is connected and composed by handle and abrasive tip, wherein abrasive tip have can with the curved-surface structure of centrifuge tube inner bottom part tight connecting.During grinding, grinding rod puts into centrifuge tube, agrees with completely bottom grinding rod and centrifuge tube, can realize the abundant grinding of tissue.The utility model can select the container of different capabilities as required, to meet the grinding of different tissues amount.What the utility model provided is disposable disposal type device, need not clean and reuse, avoid the cross pollution of sample room; And it is cheap, economical and practical.
Description
Technical field
The utility model relates to a kind of milling tool, particularly a kind of disposal type trace biological tissue milling tool.
Background technology
The abundant grinding of trace biological tissue is most important in the pre-treatment of nucleic acid extraction.In DNA bar code research process, in order to reduce the morphological disruption to voucher specimen, organizing of getting is the smaller the better as far as possible, needs organize Gamma Magnitude often, as a mite, the metapedes digitus of a fly, no matter commercially available milling tool is manual, or nucleic acid extraction often needs relatively a large amount of tissues automatically, the grinding requirement of microcomponent can not be met, owing to reusing, be easy to cause cross pollution, and cost is higher.
Summary of the invention
The purpose of this utility model is that the shortcoming overcoming prior art is with not enough, provides a kind of disposal type trace biological tissue milling tool.
The purpose of this utility model is achieved through the following technical solutions: a kind of disposal type trace biological tissue milling tool, comprises centrifuge tube and grinding rod; Grinding rod is connected and composed by handle and abrasive tip, wherein abrasive tip have can with the curved-surface structure of centrifuge tube inner bottom part tight connecting.
Described centrifuge tube is preferably transparent centrifuge tube; Be more preferably 1.5ml centrifuge tube or 0.5ml centrifuge tube.
The material of described grinding rod is preferably plastics; Be more preferably injection port by the Tip head (suction nozzle) sealed, the injection port place that Tip head seals have can with the curved-surface structure of centrifuge tube inner bottom part tight connecting.
Described Tip head is preferably the pipettor Tip head of 1ml or 0.2ml.
Described tight connecting refers to grinding rod when being positioned in centrifuge tube, and the abrasive tip of grinding rod and the inner bottom part of centrifuge tube do not have gap.
The utility model has following advantage and effect relative to prior art.
(1) centrifuge tube of different capabilities can be selected as required, to meet the grinding of different tissues amount.
(2) be disposable disposal type device, can clean, avoid the cross pollution of sample room.
(3) because the abrasive tip of grinding rod has the curved-surface structure coincide with centrifuge tube inner bottom part, there is no gap, the abundant grinding of tissue can be realized.
(4) material is the conventional centrifuge tube in laboratory and pipettor Tip head, cheap, economical and practical.
Accompanying drawing explanation
Fig. 1 is manufacturing process schematic diagram of the present utility model.
Fig. 2 is STRUCTURE DECOMPOSITION schematic diagram of the present utility model.
Wherein, the Tip head that not yet again melts of 1-centrifuge tube, 2-grinding rod, 3-.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment 1
Preparation process of the present utility model as shown in Figure 1, being placed on by the injection port of a Tip not yet again melted 3 on the naked light on alcolhol burner burns to slightly melting, immediately Tip head is firmly supported in the transparent centrifuge tube 1 of precooling, the injection port now obtaining Tip head is sealed, and the injection port place that it seals has the curved-surface structure that can coincide with centrifuge tube inner bottom part.Treat slightly to cool, take out Tip head, cool completely, obtain grinding rod 2.
Structure of the present utility model as shown in Figure 2, comprises centrifuge tube 1 and grinding rod 2; Grinding rod is connected and composed by handle and abrasive tip, wherein abrasive tip have can with the curved-surface structure of centrifuge tube inner bottom part tight connecting.Tissue to be ground is put into container, adds appropriate lysate, with grinding rod 2, tissue abrasion, grinding rod 2 agrees with completely with the inner bottom part of centrifuge tube 1, thus can fully grind micro-biological tissue.
During use, select different size container and grinding rod as required., arrange in pairs or groups as available 1ml Tip head and 1.5ml centrifuge tube and use, also can use with 0.2mlTip head and the collocation of 0.5ml centrifuge tube.The equal nucleic acid mentioning micro-biological tissue.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
