Abstract
The utility model discloses an azotification distiller and a buret thereof which belong to the field of a chemical testing instrument. Against the shortages of the existing azotification device and the buret, the outer wall of an azotification chamber of the original azotification device is cancelled, only an azotification tube part in the azotification chamber is reserved to be arranged in a steam generating bottle with a thick neck, and the binding point is in ground joint and is provided with a pressure observing tube. The part above a steam outlet of the original azotification tube and a sample adding cup are cancelled, and a sample adding cup which is coaxial with and is integrated with the azotification tube (2) is made and provided with a hollow tube plug which is in ground joint with an outlet of the azotification tube. The other end of the hollow tube plug is connected with a condenser through a rubber tube to form a complete azotification distiller. A sucking type micro buret matched with the azotification distiller is provided with a buret stopcock perfusion canceling part, and the volume is reduced.
Description
The utility model belongs to the chemical analysis instrument field.
Deciding the nitrogen distiller is to utilize the distillation principle to check the instrument of the volatile chemical of nitrogenous element to be called for short to decide the nitrogen device.Existingly decide the nitrogen device and exist and have very strong overall integrity, wherein a part of breakage then whole instrument is scrapped, complicated operation, poor safety performance.The volume ratio of instrument and auxiliary device thereof is bigger, is only limited in the laboratory to use.Existing microburet also exists shortcomings such as complicated operation, easy breakage.
The purpose of this utility model is the shortcoming of deciding the nitrogen device at above-mentioned, and it is little to have developed a kind of volume, combined type, is easy to carry, and damaged portion can be changed, and what can increase the service life novelly decides the nitrogen device.This decides the nitrogen device is to realize like this, with the nitrogen fixing chamber outer wall cancellation of original nitrogen device, only stay its inner nitrogen fixing tube part, in the steam generation bottle of the thick neck of packing into, the junction connects with ground, and a pressure observation tube is installed, pass in the bottle below the liquid level, simultaneously under the prerequisite that satisfies the condensation requirement, reduced volume to greatest extent, make whole instrument be condensed to two relatively independent parts and several widget, become a kind of combined type and be easy to carry, damaged portion can be changed novelly decides the nitrogen device.
Figure of description is an embodiment schematic diagram of the present utility model.Fig. 1 decides the combination master that each parts of nitrogen distiller are installed together to look cross section view, and Fig. 2 is the front view of buret.1 steam generation bottle among the figure, 2 nitrogen fixing tubes, 3 little grounds, 4 big grounds, 5 hollow pipes, 6 sample adding cups, 7 pressure observation tubes (bursting tube), 8 steam feeding tubes, 9 electric furnaces, 10 deionized waters, 11 checking matter filtered solutions, 12 connection sebific ducts, 13 condenser water inlets, 14 condenser delivery ports, 15 condensers, 16 drawing-in type microburets, 17 buret plugs.
Accompanying drawing below in conjunction with the embodiment that decides nitrogen distiller and buret thereof further is illustrated the utility model:
1. the nitrogen fixing chamber outer wall of former kjeldahl determination device is cancelled, only stay its inner nitrogen fixing tube (2) part to keep its steam ingress pipe (8), this part is packed in the thick neck steam generation bottle (1), both junctions connect with big ground (4), a pressure observation tube (bursting tube) (7) is installed on steam generation bottle (1) neck section start bottle wall is passed to below the liquid level that deionized water (10) in the bottle takes place.
2. cancel former nitrogen fixing tube steam (vapor) outlet with top and sample adding cup, make one and nitrogen fixing tube (2) one and coaxial sample adding cup (6), also make a hollow pipe close (5) that matches with sample adding cup (6) (the steam delivery line of holding concurrently) simultaneously.This hollow pipe close has the function of stopper, has the function of steam delivery line again, and outlet is connected with little ground (3) hollow pipe close (5) with nitrogen fixing tube (2).The other end at the hollow pipe close links to each other with condenser (15) with connecting sebific duct (12), has condenser water inlet (13) and condenser delivery port (14) on condenser (15).Decide suction and pumping that the nitrogen device matches weighing buret (16) cancellation that declines with this and pour into part, have buret plug (17) on pipe, volume dwindles greatly, and is easy and simple to handle, not cracky.
Claims (2)
1, a kind ofly decides the nitrogen distiller and it is characterized in that the nitrogen fixing tube [2] that has with one and coaxial sample adding cup [6] is put into thick neck steam generation bottle [1], the junction connects with big ground [4], pressure observation tube (bursting tube) [17] is installed on the steam generation bottle [1], pass to below the middle liquid level of steam generation bottle [1], on this sample adding cup [6], manufacture a hollow pipe close [5] that matches with this glass, hollow pipe close [5] is connected with little ground [3] with nitrogen fixing tube [2] exit, links to each other at the other end and the condenser [15] of hollow pipe close.
2, a kind of with decide the nitrogen distiller buret that uses that matches and it is characterized in that buret (16) cancellation perfusion part, buret plug (17) is installed on pipe.
