The utility model discloses a set up filter cap or the centrifugal pipe cap that convenient ann tore open at the centrifuging tube mouth of pipe, when guaranteeing to test the effect, saved experiment link and experimental device, improved the efficiency of work, and can effectively avoid centrifugal in -process liquid to splash, ensure the precision of experiment and experimental environment's cleanness, it is rational in infrastructure, easy operation, the effect is showing, is suitable for popularization and application.
Description
Technical field
This utility model relates to a kind of chemical experimental instrument, refers specifically to a kind of centrifuge tube suit with filtering function.
Background technology
In daily chemical laboratory, it is often necessary to some samples are carried out solid-liquid centrifugation separating treatment, after sample is performing centrifugal separation on, solid residue is frequently not and is attached to centrifugal tube wall, but is broken into bigger bulk and floats on a liquid.In order to carry out next step experiment, need to pour out liquid, remaining solid residue in centrifuge tube.And the relatively time-consuming effort of this process, need cautious operation, in case solid residue is together flowed into liquid below with liquid and receives in container, next step experiment is caused unnecessary trouble, affects experiment effect.At present, in order to ensure there being preferable experiment effect, the funnel with filter paper is generally used to carry out fine filtering.But this adds increased experiment link, cause extra work amount and burden, virtually extend the test period.Therefore, need a kind of centrifuge tube with filtering function of design badly to be set with, to solve above-mentioned technical problem.
Utility model content
For above-mentioned technical problem, this utility model provides a kind of centrifuge tube suit with filtering function, while guaranteeing experiment effect, effectively saves experiment link, significantly improves the efficiency of work.
This utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of centrifuge tube suit with filtering function, including centrifuge tube, the upper orifice compact siro spinning technology of described centrifuge tube has filter cap, and the upper outlet end face of filter cap is coated with drainage screen, and the edge that filter cap contacts with drainage screen is provided with guiding gutter.
Further, described centrifuge tube suit also includes centrifugal pipe cap close-connected with centrifuge tube upper orifice, and the upper end of centrifugal pipe cap is closed.
Further, the external wall of upper portion of described centrifuge tube is provided with external screw thread, and the inwall of filter cap or centrifugal pipe cap is provided with female thread, and centrifuge tube passes through internal and external screw thread screwing hermetic with filter cap or centrifugal pipe cap.
Further, described centrifuge tube, filter cap and centrifugal pipe cap are made by hard corrosion-resistant plastic.
Further, a diameter of 2mm～4mm of the filtering holes of described drainage screen.
The beneficial effects of the utility model are:
1, the filter cap torn open is conveniently pacified by arranging at the centrifuge tube mouth of pipe, it is ensured that while experiment effect, save experiment link and experiment equipment, improve the efficiency of work；
2, conveniently pacify the centrifugal pipe cap torn open by arranging at the centrifuge tube mouth of pipe, liquid splash in centrifugal process can be prevented effectively from, it is ensured that the precision of experiment and the cleaning of experimental situation；
3, rational in infrastructure, simple to operate, effect is notable, is suitable to popularization and application.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1-centrifuge tube, 2-filter cap, 3-drainage screen, 4-guiding gutter, 5-is centrifuged pipe cap.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model and effect thereof are further elaborated.
As shown in Figure 1, a kind of centrifuge tube suit with filtering function, including centrifuge tube 1, filter cap 2 and centrifugal pipe cap 5, the lower space of centrifuge tube 1 is used for containing laboratory sample to be centrifuged, the upper orifice of centrifuge tube 1 and filter cap 2 compact siro spinning technology, primarily serve the filtration carried out the sample after being centrifuged when supernatant is toppled over；The upper end of filter cap 2 is coated with drainage screen 3, and the edge that filter cap 2 contacts with drainage screen 3 is provided with guiding gutter 4.Drainage screen 3 is positioned at filter cap 2 top exit, high-density plastic's bar in length and breadth weave and form, define substantial amounts of filtering holes, and the diameter of filtering holes is about at 2mm～4mm, to ensure the purity of isolated extract.Extract flows out from filtering holes, and solid residue has remained in centrifuge tube 1, it is achieved that effective solid-liquid separation.
Further, described centrifuge tube suit also includes centrifugal pipe cap 5 close-connected with centrifuge tube 1 upper orifice, the top end face closure of centrifugal pipe cap 5.When laboratory sample is centrifugal in centrifuge, being tightened on centrifuge tube 1 by centrifugal pipe cap 5, when can effectively prevent centrifugal, liquid splash goes out.This centrifuge tube suit entirety, i.e. centrifuge tube 1, filter cap 2 and centrifugal pipe cap 5 is made by hard corrosion-resistant plastic.
More specifically, the upper orifice outer wall of centrifuge tube 1 is provided with external screw thread, the inwall of filter cap 2 or centrifugal pipe cap 5 is provided with female thread, centrifuge tube 1 coordinates screwing hermetic with filter cap 2 or centrifugal pipe cap 5 by internal and external screw thread, to prevent liquid from outflowing from side leakage, pollute experiment table top or the health of human body of experimenter is threatened.
In practical operation, first laboratory sample is loaded in centrifuge tube 1, centrifugal pipe cap 5 is covered tightly on centrifuge tube 1, centrifuge carries out centrifuging treatment；After being centrifuged, screw off centrifugal pipe cap 5, then filter cap 2 is screwed with centrifuge tube 1, by the drainage of guiding gutter 4 extract in centrifuge tube 1 toppled over and separate；Unscrewed filter cap 2, pours out the solid residue in centrifuge tube 1, is carried out, centrifuge shield dress in case next time reuses.This utility model effectively saves the experiment link using some complexity such as filter paper, funnel, improves work efficiency, has saved experiment equipment, it is ensured that good experiment effect.
Above example is only exemplary; this utility model can't be limited to, it should be pointed out that for a person skilled in the art, under technology provided by the utility model is enlightened; other equivalent modifications made and improvement, be regarded as protection domain of the present utility model.
