Abstract

The utility model discloses a mercury vapor reducing bottle, wherein the upper mouth of the bottle body is blocked with a rubber bottle plug; the rubber bottle plug is inserted with a gas carrier pipe, a filling pipe and an escape pipe which pass through the thickness of the rubber bottle plug; the lower mouth of the gas carrier pipe is inserted to the bottom of the cavity of the bottle body; and the upper mouth of the filling pipe is blocked with a rubber hose plug. The reducing bottle is used for reducing the contained mercury when determining the sample mercury content, replaces the reducing bottle matched with the original instrument, and is not easy to damage and easy to repair after being damaged; and the mercury vapor is not leaked when in measuring, and the reducing bottle ensures the result accuracy, greatly improves the working efficiency, is convenient and practical, and is convenient for promotion at the basic level.

Description

Mercury vapour reduction bottle

Technical field:

The utility model relates to a kind of mercury vapour reduction bottle, is used for the mercury that reduction contained when the sample mercury content measured.

Background technology:

The assay method of total mercury is used cold-vapour atomic absorption method mostly in basic unit's food, water, the cosmetics at present, the various mercury vapourmeters that are fit to this method need be formed with the absorption bottle of reduction bottle that produces mercury vapour and the surplus mercury of absorption, only supporting five glass reduction of general new instrument bottle, bottleneck glass ground joint plug band inserts the carrier gas pipe of liquid and goes out the mercury vapour pipe, the glass ground joint stopper is perishable, especially down insertion liquid carrier gas pipe is easily broken, inserts less than the liquid level bottom and does not have the effect that the abundant reaction of bubble is turned in air blowing, and this bottle can only be scrapped.After adding the stannous chloride reducing agent during operation, lid reduction bottle stopper is untimely, makes mercury vapour effect of flood assay easily.The neophyty operation that has is in a rush, and reduction bottle is toppled over, and liquid is entered in the absorption cell, even absorption bottle all done down, brings very burden to testing.

Summary of the invention:

The purpose of this utility model provides a kind of mercury vapour reduction bottle, solves original reduction bottle and damages a problem that is not easy to repair easily, solves the problem that the mercury vapour that reduces overflows easily.

The purpose of this utility model realizes as follows: a bottle is arranged, the bottle bottle closure of rubber that is plugged with suitable for reading, be inserted with the carrier gas pipe, filler pipe and the escape pipe that pass its thickness on the bottle closure of rubber, carrier gas pipe end opening is inserted into the bottle intracavity bottom, the suitable for reading stifled rubber pipe close that has of filler pipe.The carrier gas pipe is used for logical carrier gas in bottle; Escape pipe is connected with plastic tube with the absorption bottle that absorbs surplus mercury, cooperates mercury vapourmeter to use, and the sample mercury content is measured; The filler pipe reducing agent stannous chloride that is used to annotate.Bottle closure of rubber is not easy to damage, and for dividing body structure, extracts out after damaging and just can change between carrier gas pipe, filler pipe, escape pipe and the bottle closure of rubber.When surveying the mercury experiment bottle is put into rack for test tube, bottle can not forgotten about it, and guaranteed that absorption bottle can not topple over yet, use syringe during the filling stannous chloride, pressing fixed qty by punctures rubber pipe close adds, one man operation can not make mercury vapour reveal yet, and has guaranteed result's accuracy, and testing is carried out smoothly.

The utility model replaces the supporting reduction bottle of former instrument, is not easy to damage, and damages the back and repair easily; Mercury vapour can not revealed during measurement, has guaranteed result's accuracy, increases work efficiency greatly, and is convenient and practical, is convenient to basic unit and promotes the use of.

Description of drawings:

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment:

With reference to accompanying drawing, bottle 1 bottle closure of rubber 2 that is plugged with suitable for reading is inserted with the carrier gas pipe 3, filler pipe 4 and the escape pipe 6 that pass its thickness on the bottle closure of rubber 2, and carrier gas pipe 3 end openings are inserted into bottle 1 intracavity bottom, the suitable for reading stifled rubber pipe close 5 that has of filler pipe 4.Use syringe, punctures rubber pipe close 5 is by the filler pipe 4 stannous chloride reducing agent of annotating in bottle 1.

Claims
