Description
Technical field
The utility model relates to experiment appliances to fabricate field, more particularly to a kind of 1765 kjeldahl determination distillation reaction rooms
Device.
Background technique
Currently, 1765 common kjeldahl determination distilling apparatus are standard mouth glass apparatus, device connection is simple and convenient, reaction
Room injection port has a glass ground joint plug, and when sample introduction need to remove plug, and concentrated base and sample to be tested are successively by injection port sample introduction.When dense
Alkali mixes moment with sample can be highly exothermic, and reaction acutely, in actual use, also has not enough time to cap, reacts
The sub-fraction ammonia of generation can escape reaction chamber through injection port, bring error to measuring.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of distillations of 1765 kjeldahl determinations of favorable sealing property
Reaction chamber apparatus.
To solve the above problems, a kind of 1765 kjeldahl determination distillation reaction chamber device described in the utility model, including it is anti-
Answer chamber, it is characterised in that: the bottom end of the reaction chamber is equipped with waste air fluid catheter, and side is equipped with connection steam evaporator
Conduit I, it is intracavitary be equipped with vapor conduit, top be equipped with conduit II；The conduit II passes through buffering ball warp beam ground connection
Condenser pipe, and be connected by sample introduction conduit with injection port；The injection port is connected with the vulcanie plug with grass tube；The glass
The top of glass conduit is cased with latex cap, and the syringe needle of syringe is inserted on the latex cap.
The vulcanie is equipped with aperture beyond the Great Wall, and is connected as one by the aperture and the grass tube.
The waste air fluid catheter is equipped with the hose sealed through butterfly clamp.
Compared with the prior art, the utility model has the following advantages:
1, vulcanie is equipped with aperture beyond the Great Wall in the utility model, and is connected as one by the aperture with grass tube,
And the top of grass tube is cased with latex cap and it is fully sealed, when the concentrated base for drawing certain volume with syringe, by syringe
Syringe needle insertion latex cap in, be pushed into concentrated base.During concentrated base is mixed with sample, system is fully sealed, and avoids concentrated base
Chamber is reacted through injection port evolution with the ammonia that sample Contact generates, but all enters condenser pipe quilt via beam ground
It absorbs, to reduce the error of measuring.
2, it is equipped with buffering ball in the utility model, can avoid reaction solution in operating process and spray.
3, the latex cap in the utility model can be replaced, and replacement cost is cheap, easy to operate, thus keeping body
It is favorable sealing property.
Detailed description of the invention
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1-syringe；2-latex caps；3-grass tubes；4-vulcanie plugs；5-injection ports；6-standards
Ground；7-sample introduction conduits；8-buffering balls；9-conduits II；10-conduits I；11-reaction chambers；12-vapor conduits；
13-waste air fluid catheters.
Specific embodiment
As shown in Figure 1, a kind of 1765 kjeldahl determination distillation reaction chamber devices, including reaction chamber 11.React chamber 11
Bottom end be equipped with waste air fluid catheter 13, side be equipped with connection steam evaporator conduit I 10, it is intracavitary be equipped with vapor conduit
12, top is equipped with conduit II 9；Conduit II 9 by buffering ball 8 through beam ground 6 connect condenser pipe, and by sample introduction conduit 7 with
Injection port 5 is connected；Injection port 5 is connected with the vulcanie plug 4 with grass tube 3；The top of grass tube 3 is cased with 2 shape of latex cap
At confined reaction system, the syringe needle of syringe 1 is inserted on the latex cap 2.
Wherein: vulcanie plug 4 is equipped with aperture, and is connected as one by the aperture with grass tube 3.
Waste air fluid catheter 13 is equipped with the hose sealed through butterfly clamp.
In use, connecting steam evaporator by conduit I 10, condenser pipe is connected by beam ground 6, by waste discharge gas-liquid
Conduit 13 is sealed by hose and butterfly clamp.Then the entirety that vulcanie plug 4 and grass tube 3 form is opened, by injection port 5
The sample to be tested digested is poured into, sample, which enters via sample introduction conduit 7 with conduit II 9, reacts chamber 11.Vulcanie plug 4 beyond the Great Wall
The entirety formed with grass tube 3, by 2 sets of latex cap above grass tube 3, latex cap 2 is fully sealed with grass tube 3,
There is no gap.The concentrated base that certain volume is drawn with syringe 1 is pushed into concentrated base in the syringe needle insertion latex cap 2 of syringe 1.In
During concentrated base is mixed with sample, system is fully sealed, and avoids the ammonia of concentrated base and the generation of sample Contact through sample introduction
5 evolution reaction chambers 11 of mouth, but be all absorbed via beam ground 6 into condenser pipe, to reduce the mistake of measuring
Difference.Steam evaporator is opened, vapor enters reaction chamber 11 via conduit I 10 and vapor conduit 12, and buffering ball 8 can be kept away
Exempt from reaction solution in operating process to spray.Latex cap 2 is after using 5 ~ 10 times, in order to keep system favorable sealing property, Ke Yijin
Row replacement.
