Abstract
The utility model discloses a kind of lucifuge test tube frame, including top plate, middle plate, lower plywood and two supporting plates positioned at side, difference from prior art to be:The lower section of supporting plate is provided with a curtain rolling shaft, and the both ends of curtain rolling shaft are individually fixed in the same side of two supporting plates, and with curtain rolling shaft with the soft curtain of shading and cross bar is arranged with, the support for shelving cross bar is respectively provided with the middle part of supporting plate and top.Described support is arranged in pairs, and sliding groove and handle are additionally provided with the outside of the supporting plate.Sliding groove and handle are arranged with the outside of the supporting plate of opposite side.
Description
Technical field
The utility model belongs to test apparatus technical field, and in particular to a kind of lucifuge test tube frame.
Background technology
Rack for test tube is one kind of chemical experimental instrument.Rack for test tube is (test tube can also to be positioned over to examination sometimes for placing
On pipe support, observe some experiment phenomenon), dry test tube chemical laboratory most basic laboratory apparatus.In rack for test tube
Duckpin and aperture with respective number.It is foraminate test tube can be placed vertically it is stand-by or to continue the progress of observing response.
There is clean test tube being put upside down for post, to dry.
Existing rack for test tube be typically all be made up of top plate, lower plywood and support side plate, test tube be placed into top plate and
In the test tube hole of lower plywood, because some samples need the particular/special requirements such as lucifuge, refrigeration, illumination and heating, experimenter have to be
It is placed on after pipette samples on general rack for test tube, then rack for test tube is put among the box or closet of lucifuge etc., this
It is not only inconvenient a bit, it is easier to therefore occur situations such as cause assay error, or even the normal measure of sample can not be ensured.
The especially determination of activity of natural plant extract, measure needs lucifuge, it is necessary to which taking away other rooms or position carries out instrument point
Analysis, for safety and conveniently, it is necessary to design a kind of shading rack for test tube.
Utility model content
For weak point of the prior art, the utility model provides a kind of lucifuge test tube frame, can be in needs
When shield lights.
Technical scheme:Lucifuge test tube frame provided by the utility model, including top plate 1, middle plate 2, lower plywood 3 and
Two supporting plates 4 positioned at side, difference from prior art is:The lower section of supporting plate is provided with a curtain rolling shaft 5, roller shutter
The both ends of axle 5 are individually fixed in the same side of two supporting plates, with curtain rolling shaft with the soft curtain 6 of shading and cross bar 7 is arranged with, are supporting
The middle part and top of plate are respectively provided with the support 8 for shelving cross bar.Described support 8 is arranged in pairs, outside the supporting plate 4
Side is additionally provided with sliding groove 9 and handle 10.Sliding groove and handle are arranged with the outside of the supporting plate of opposite side.
Top plate 1 and middle plate 2, which are provided with, is available for the through hole that test tube is put into.Test tube is facilitated to place, and top plate and middle level
Vertically corresponded between the through hole of plate.
Further, lower plywood 3 is provided with groove corresponding with through hole.So that the placement of test tube is more stable.
Lucifuge is set used by the utility model, is symmetrical, in the opposite side of two supporting plates, is rolled up provided with symmetrical
Curtain axle, the soft curtain of shading, cross bar, support.Also, described supporting plate is light-proof material.Rack for test tube entirety can so be ensured
In lighttight state.
Beneficial effect:For fields such as chemistry and biologies, have and much react if illumination will produce deleterious effect,
Lucifuge is needed to carry out, and the mode that often we take is that the containers such as the test tube equipped with reaction solution are placed on to the place of dark,
Question response takes out carry out follow-up work again after terminating.But so there is the defects of many fatal, to time, follow-up measuring apparatus
Position etc. is proposed very high requirement, is not so likely to cause the failure of experiment, wastes medicine, solvent, also have lost
Substantial amounts of time and efforts.This equipment easily can perfectly solve these problems.Reaction solution band can no longer hold the post whenever and wherever possible
What place, fully meets requirement of experiment.The especially design of the handle of rod-pulling type so that it is more convenient to carry.

Embodiment:
The utility model is described in detail below by specific embodiment.
As shown in figure 1, lucifuge test tube frame includes top plate 1, middle plate 2, lower plywood 3 and two supports positioned at side
Plate 4, the lower section of supporting plate are provided with a curtain rolling shaft 5, and the both ends of curtain rolling shaft 5 are individually fixed in the same side of two supporting plates, with
Curtain rolling shaft is respectively provided with the support for shelving cross bar at the middle part of supporting plate and top with the soft curtain 6 of shading and cross bar 7 is arranged with
8.Described support 8 is arranged in pairs.The outside of the supporting plate 4 is additionally provided with sliding groove 9 and handle 10.In the supporting plate of opposite side
Outside be arranged with sliding groove and handle.Handle 10 is usually taken in into sliding groove 9, when needing mobile take away, by handle 10
Extract out and be easily carried.
Exemplified by using antioxidant activity tests of the scavenging ability of DPPH free radical to determine Flavonoid substances, measuring
Before, prepare 0.1mmol DPPH ethanol solutions.The accurate various concentrations Flavonoid substances sample aqueous solution for drawing 2.0ml and
The DPPH solution of 6.0ml Fresh is in test tube, and uniformly mixing, test tube is put into above-mentioned rack for test tube, then by shading
Soft curtain is pulled out from curtain rolling shaft, and cross bar is held on support, and whole rack for test tube is in light protected environment, lucifuge reaction
30min.Its absorbance, record data are determined at 517nm.Blank control replaces sample liquid to determine second with isometric distilled water
In alcoholic solution before unreacted DPPH absorbance.Using sample liquid concentration as abscissa, free radical scavenging activity is mapped for ordinate
Analyze the ability that sample removes free radical.
