Abstract
The utility model relates to a liquid separator for a colorimetric pipe. The upper part of the liquid separator has a mouth grinding plug; a switch plug is sheathed on the horizontal pipe of a liquid separating pipe on the lower part; the lower part of the liquid separating pipe has an air inlet pipe. The utility model is matched with the colorimetric pipe for use to make test liquid layered for discharge. The utility model has the advantages of simple operation and accurate test.
Description
The utility model relates to a kind of inspection for food hygiene instrument.
In inspection for food hygiene, when adopting chemical determination lead, zinc, copper, cadmium, need to use separating funnel to extract separatory, it operates comparatively loaded down with trivial details effort.Present much human color comparison tubes replace separating funnels, and sample is absorbed the upper strata water with aspiration pump or vacuum pump and carried out colorimetric estimation after extracting layering, and this method has increased running program, and the difficult absorption of water fully, brings certain difficulty to colorimetric.
Order of the present utility model provides a kind of and the supporting use knockout of color comparison tube, and this knockout can be removed the technology of absorbing water from.
The purpose of this utility model realizes by following measure, the grinding port plug 3 of pegging graft with the bottleneck of color comparison tube 1 is arranged at the top of this color comparison tube knockout, grinding port plug 3 bottoms connect separating tube 6, the endoporus of separating tube 6 communicates with the hollow space of grinding port plug 3, transverse tube 2 internal fixation cock plugs 4 on the separating tube 6, draft tube 5 is arranged at separating tube 6 bottoms.
Between grinding port plug 3 and separating tube 6, the cambered surface hollow body is arranged.
Narrate below in conjunction with drawings and Examples.
Fig. 1 is the overall construction drawing of knockout.
Fig. 2 is the wiring layout of knockout and color comparison tube.
With reference to Fig. 1 is an embodiment of the present utility model, and its structure wherein has the cambered surface hollow body as mentioned above between grinding port plug 2 and the separating tube, and this knockout is a glassware.
During use, food samples to be tested is processed into standard sample, put into color comparison tube and extract separatory, take off the bottle stopper of color comparison tube, use the bottleneck of the grinding port plug 3 sealing color comparison tubes of knockout, color comparison tube is inverted, divide layer open cock plug 4, access organic phase with different containers, put into cuvette for colorimetric usefulness, draft tube 5 make-up gas during discharge opeing.
This knockout is easy to use, the testing accuracy height.
Claims (2)
1, a kind of color comparison tube knockout, the grinding port plug 3 of pegging graft with the bottleneck of color comparison tube 1 is arranged at the top that it is characterized in that it, and grinding port plug 3 bottoms connect separating tube 6, and the endoporus of separating tube 6 communicates with the hollow space of grinding port plug 3, transverse tube 2 internal fixation cock plugs 4 on the separating tube 6, draft tube 5 is arranged at separating tube 6 bottoms.
2, knockout according to claim 1 is characterized in that between grinding port plug 3 and separating tube 6 the cambered surface hollow body being arranged.
