Abstract
The invention discloses a test tube capable of preserving heat. The upper end of the test tube is an opening part, and the lower end is a spherical sealing bottom part. The test tube is characterized in that an outer layer and an inner layer are arranged from the opening part to the spherical sealing bottom part; an interlayer is arranged in the middle of the outer layer and the inner layer; and the opening part at the upper end of the interlayer is sealed by a sealing ring. With adoption of the heat preservation test tube adopting a double-layer vacuumizing structure, a liquid sample can keep temperature in a certain time and does not need to be placed in a water bath box for heating, the use is convenient, and the experiment/detection speed is improved. In addition, energy source can be effectively saved, cross-infection of the sample in the water bath box is avoided, and the correctness and the authenticity of a detection result are ensured.
Description
Technical field
The present invention relates to a kind of test tube, particularly a kind of test tube with self heat insulation function.
Background technology
Test tube is the most frequently used glass apparatus in laboratory, for the various solution of splendid attire or reagent.Sometimes, laboratory gathers or the solution to be checked of preparation (for example: 37 ℃ of blood samples) has certain temperature, after test tube splendid attire, can not detect at once, sample temperature can decline rapidly under room temperature state, can not meet the requirement of detection Deng being loaded into temperature on instrument, now can cause sample waste.Therefore, after sampling/configuration, often needing that sample is put into water bath together with test tube is incubated.
So, both increase the preparation link of experiment, strengthened again the cross-infection chance of sample in water bath.In order to increase work efficiency, accelerate experiment turnaround speed, develop the concern that a kind of test tube with self heat insulation function is more and more subject to people.
Summary of the invention
The test tube that the object of this invention is to provide a kind of thermal convection current that can significantly reduce sample and heat conduction velocity, self can be incubated.
For reaching above object, the present invention takes following technical scheme to be achieved:
But a test tube for self insulation, upper end is peristome, and lower end is spherical back cover portion, it is characterized in that, from peristome, to spherical back cover portion, is provided with skin and internal layer, in the middle of outer and internal layer, be interlayer, and this interlayer is located to be shut by seal ring in upper end open portion.
In such scheme, in described interlayer, be evacuated.In described interlayer, can be filled with transparent insulation material.The described interlayer filling chemistry heat production agent that is arranged in spherical back cover portion, has pin hole in test tube upper end open portion place's seal ring and is communicated with interlayer, and this pin hole seals at ordinary times, and the used time opens.
The present invention utilizes double layer glass structure (vacuum-pumping, can fill insulant material), effectively reduces thermal convection current and the heat conduction of sample to be tested, can the long period maintain sample temperature, easy to use, experiment turnaround speed is fast, increases work efficiency.Meanwhile, cancelled and put into the test tube heat preserving method that water bath is heated, can effectively save the energy, avoided the cross-infection of sample in water bath, guaranteed the correctness and the authenticity that detect.
Accompanying drawing explanation
Fig. 1 is a structural representation of test tube of the present invention.
Fig. 2 is another structural representation of test tube of the present invention.
In Fig. 1, Fig. 2: 1, skin; 2, internal layer; 3, interlayer; 4, seal ring; 5, spherical back cover portion; 6, chemical heat production agent; 7, pin hole.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Embodiment mono-
As shown in Figure 1, but a kind of test tube self being incubated, upper end is peristome, and lower end is spherical back cover portion 5, from peristome, to spherical back cover portion 5, is double-layer glass structure, comprise outer 1, internal layer 2, skin 1 is middle with internal layer 2 is interlayer 3, this interlayer 3 is shut by seal ring 4 at upper end open portion place, this interlayer is hollow layer, can be evacuated.The present embodiment double-layer vacuum test tube, through blood sample checking, in same temperature tolerance band to be checked (37 ± 1 ℃), double-layer vacuum test tube heat insulation effect (5.0min) is 5 times of conventional monolayers teat glass (1min), has met the requirement of experiment.
Embodiment bis-
Can the transparent insulation material of filling in skin in Fig. 11 and internal layer 2 intermediate courses 3, as the transparent slurry of antimony tin (ATO) water-borne heat-insulating, this material has good transmitance at visible region (380～780nm), and near infrared region, (780～2500nm) has high barriering rate, high insulating effect, through blood sample, verify, in same temperature tolerance band to be checked (37 ± 1 ℃), fill transparent insulating layer test tube heat insulation effect (4.9min) and approach the heat insulation effect vacuumizing.
Embodiment tri-
As shown in Figure 2, filling chemistry heat production agent 6 in the skin 1 of spherical back cover portion 5 and internal layer 2 intermediate courses 3, in test tube upper end open portion place's seal ring 4, have pin hole 7 and be communicated with interlayer 3, sealing when this pin hole 7 is flat, used time opens, make air and the slow heat production of chemical heat production agent 6 effect, realize in vitro solution sample and be incubated by automatic passive.It is heat production agent that chemistry heat production agent 6 can adopt the oxidizable thin iron powder of ingress of air, the loading of the pore size of choose reasonable pin hole 7 and chemical heat production agent 6, i.e. adjustable slowly-releasing temperature, heat insulation effect can regulate at 20～40 ℃, use flexibly, be applicable to the insulation requirement of different samples.
