The test tube provided by the utility model is simple to operate, accurate to heat, high in test success rate and high in safety.
Description
Technical field
The utility model relates to a kind of general chemical laboratory installation, is specifically related to a kind of test tube.
Background technology
For guaranteeing the validity of chemical test; some experimental condition has clear and definite temperature requirement to participating in the reagent of reaction; but existing test tube is because mode that only can be by external heat heats reagent in vitro, cause that complicated operation, temperature of reagent cannot be monitored, test failure rate is high, danger coefficient is large.
Utility model content
The purpose of this utility model is to provide a kind of simple to operate, temperature of reagent is easily monitored, safety coefficient is high test tube.
The concrete technical scheme that the utility model adopts is as follows:
A kind of test tube, it is characterized in that: comprise body, cage, fixed leg, heating wire, sealing-in cap and draw wire, cage is fixedly installed in body, fixed leg is fixed on sealing-in cap, heating wire winding, on fixed leg, is drawn wire and is connected with heating wire through sealing-in cap.
Its beneficial effect is that reagent can directly heat by heating wire in body, has simplified test operation program, has improved the security of test operation.
In some embodiments, body and cage material are quartz glass.
Its beneficial effect is that quartz glass material is acid and alkali-resistance and high temperature resistant effectively, has both guaranteed that good heat-conducting effect has also guaranteed the service life that test tube is longer.
In some embodiments, body is provided with temperature sensor.
Its beneficial effect is that temperature sensor can directly react the temperature of reagent in body, is convenient to control in time temperature of reagent.
In some embodiments, body is provided with injection port.
Its beneficial effect is, injection port has guaranteed that reagent enters the security of body and convenient.
In some embodiments, fixed leg is fixed on sealing-in cap center.
Its beneficial effect is fixed leg to be fixed on to sealing-in cap center and can to guarantee the balance of test tube weight and guarantee that cage is heated even.
In some embodiments, described heating wire is wrapped on fixed leg with helical form.
Its beneficial effect is, guaranteed that stability that heating wire is placed further guaranteed that cage is heated evenly
Accompanying drawing explanation
Fig. 1 is the utility model cutaway view
Reference numeral:
Body 1, cage 2, fixed leg 3, heating wire 4, sealing-in cap 5, draws wire 6, temperature sensor 7, injection port 8
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
Test tube is mainly by body 1, cage 2, fixed leg 3, heating wire 4, sealing-in cap 5 with draw wire 6 and form, cage 2 is fired in body 1, body 1 afterbody is by 5 sealings of sealing-in cap, fixed leg is fixed on sealing-in cap 5, and heating wire 4 is wrapped on fixed leg 3 and with the wire 6 of drawing through sealing-in cap 5 and welds.
Body 1 plays test reaction vessel, cage 2 is isolated cover interior or exterior space completely and plays heat conduction, fixed leg 3 plays fixedly heating wire 4,4 heat effects of heating wire, sealing-in cap 5 had not only played the effect of fixing fixed leg 3 but also had played heat insulation effect, and drawing 6, wire is heating wire 4 power supply functions.
The material of body 1, cage 2 is quartz glass, be mainly utilize that quartz glass heat conduction is good, acid and alkali-resistance, corrosion resistant feature, the reagent that the heat energy that heating wire 4 can be produced pass in body 1 fast by cage 2 can guarantee that again test tube is longer service life.
Temperature sensor 7 is arranged on body 1 surface, and the tube wall of body 1 is passed to body 1 in its sensing part, both can realize the immediately monitoring to body 1 interior temperature of reagent, has guaranteed carrying out smoothly of test.
Injection port 8 has been fired on body 1 surface, is mainly to enter the security of body 1 and convenient in order to ensure reagent.
The center that fixed leg 3 inserts sealing-in cap 4, guarantees under the prerequisite of whole test tube weight balancing, more guarantees that cage 2 can thermally equivalent.
Heating wire 4 is wrapped on fixed leg in spiral helicine mode, both guaranteed heating evenly also guaranteed that cage 2 is heated evenly.
Above-described embodiment is only for the inventive concept of the present utility model of explaining; but not the restriction that utility model right is protected; all utilize this design to carry out that form equivalent variations, equivalent substitute etc. to the utility model unsubstantiality is changed, all should fall into protection domain of the present utility model.
