Abstract

The utility model discloses a kind of new iodine flask, it includes bottle and bottle stopper, it is characterised in that it also includes pig tail catheter, and the big opening end rotary clamping of pig tail catheter is fixed on the bottom of bottle stopper.Beneficial effect：A piece conduit is set in iodine flask, and reaction solution can completely react with load weighted iodine powder, it is ensured that the accuracy of experimental result, while avoiding waste iodine powder, experimental cost is reduced；Conduit bottom end outlet is arranged on above iodine flask bottom, and bottleneck is small, and the iodine powder volatile quantity for falling into iodine flask is small, it is to avoid because forget water seal or water seal it is excessively slow occur a large amount of iodine powder volatilizations, it is ensured that the success rate of experiment；Easy realization simple in construction, it is easy to operate.

Description

A kind of new iodine flask

Technical field：

The utility model is related to a kind of bottle, more particularly to a kind of new iodine flask.

Background technology：

During existing iodine flask addition iodine powder, easily there is the phenomenon that iodine powder is stained with iodine flask inwall；When testing, The solution reacted with iodine powder is poured into iodine flask, rocked because during the course of the reaction, iodine flask can not turn upside down, so using Existing iodine flask carries out experiment and there is problems with：1st, sticking in the iodine powder of iodine flask upper inside wall can not fully react, increase The error of experiment, makes experimental result inaccurate, while wasting iodine powder, adds experimental cost；2nd, iodine is with volatility , therefore need to carry out water seal between bottleneck and bottle stopper to iodine flask during the course of the reaction, when forgetting water seal or water seal Cross slow, then occur that iodine powder volatilizees, cause experimental error to increase, or even the failure of an experiment.

Utility model content：

The purpose of this utility model is to provide a kind of experimental result accurately, and the volatilization of iodine powder is small and iodine powder can be made fully to react New iodine flask.

The utility model is implemented by following technical scheme：A kind of new iodine flask, it includes bottle and bottle stopper, and it also includes Pig tail catheter, the big opening end rotary clamping of the pig tail catheter is fixed on the bottom of the bottle stopper.

Further, provided with two relative fixture blocks on the side wall below the bottle stopper；In the big mouth of the pig tail catheter The side wall at end is provided with two L-shaped necks being engaged with the fixture block.

Advantage of the present utility model：The 1st, a piece conduit is set in iodine flask, and reaction solution can be with load weighted iodine Powder reacts completely, it is ensured that the accuracy of experimental result, while avoiding waste iodine powder, reduces experimental cost；2nd, conduit bottom Bring out mouth to be arranged on above iodine flask bottom, and bottleneck is small, the iodine powder volatile quantity for falling into iodine flask is small, it is to avoid because forgetting water seal Or water seal occurs a large amount of iodine powder volatilizations slowly excessively, it is ensured that the success rate of experiment；3rd, easy realization simple in construction, operation side Just.

Brief description of the drawings：

Fig. 1 is overall structure diagram of the present utility model.

Fig. 2 is the assembling schematic diagram of bottle stopper and conduit.

Bottle 1, bottle stopper 2, conduit 3, fixture block 4, neck 5, bottleneck 6, bottleneck 7.

Embodiment：

Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.

As shown in figure 1, a kind of new iodine flask, it includes bottle 1 and bottle stopper 2, and it also includes pig tail catheter 3, and taper is led The big opening end rotary clamping of pipe 3 is fixed on the bottom of bottle stopper 2；Provided with two relative fixture blocks 4 on side wall below bottle stopper 2； Provided with two L-shaped necks 5 being engaged with fixture block 4 on the side wall of the big opening end of pig tail catheter 3.

Operation instruction：Conduit 3 is put into bottle 1, the big opening end side wall of conduit 3 is installed on the bottle 1 of the lower section of bottleneck 6 On inwall, and the inwall of bottle 1 of the edge of neck 5 and the lower section of bottleneck 6 is brought into close contact on conduit 3, then by load weighted iodine powder from Bottleneck 7 is poured into, and iodine powder is flowed into bottle 1 along bottleneck 7 through conduit 3, is then again poured into reaction solution, and reaction solution can be by The iodine powder being stained with the inwall of conduit 3 is flushed in bottle 1, and iodine powder can fully react；Bottle stopper 2 is put into bottleneck 7, blocked simultaneously Block 4 is slipped into neck 5, is brought into close contact the inwall of the outer wall and bottleneck 7 of the bottle stopper 2 of the top of fixture block 4, then to the top of bottle stopper 2 Bottleneck 7 carries out water seal；When forget water seal or water seal it is excessively slow when, due to conduit 3 big opening end side wall with the lower section of bottleneck 6 Wall is brought into close contact, and the mouth of pipe bore of the bottom of conduit 3 is small, the iodine volatile quantity in bottle 1 is small, it is to avoid because forgetting water seal or water A large amount of iodine powder that occur slowly excessively of envelope volatilize, it is ensured that the success rate of experiment；Need to pour out the liquid in bottle 1 after having reacted When, bottle stopper 2 only need to be rotated, the fixture block 4 on the wall of bottle stopper 2 is laterally connected in the neck 5 on conduit 3, while taking out bottle stopper 2 Also conduit 3 is taken out, then liquid is poured out from bottleneck 7.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model Protection domain within.

Claims (2)

1. a kind of new iodine flask, it includes bottle and bottle stopper, it is characterised in that it also includes pig tail catheter, and the taper is led The big opening end rotary clamping of pipe is fixed on the bottom of the bottle stopper.

2. a kind of new iodine flask according to claim 1, it is characterised in that be provided with the side wall below the bottle stopper Two relative fixture blocks；Provided with two L-shaped necks being engaged with the fixture block on the side wall of the pig tail catheter big opening end.
