Description
Technical field
The utility model relates to a kind of glasswares of Biochemical Lab, and in particular to be a kind of cloth disease tube agglutination
Test tube is aggregated used in test.
Background technique
Cloth disease tube agglutination test (SAT) is a kind of stability, specificity, the higher detection method of sensibility, is always
Various countries are used as the conventional serological diagnostic method of diagnosis humans and animals brucellosis, and China is classified as animal brucellosis
The legal formal test of the national standard of diagnosis.According to GB/T 18646-2002, in examining for animal brucellosis (hereinafter referred to as cloth disease)
In disconnected technology, " rose bengal precipitation test (RBPT), cow full milk ring test (MRT) are suitable for domestic animal cloth disease Field Screening
Test and the monitoring of dairy farm cloth disease and the Primary Screening Test for diagnosing lactating cow cloth disease；Tube agglutination test (SAT) and complement knot
Close the domestic animal that test (CFT) is suitable for diagnosing sheep kind, ox kind and the infection of pig kind cloth disease ".
However, the interpretation of test result is artificial eye interpretation, i.e., all the time in cloth disease tube agglutination test method
It visually observes in test tube by the agglutination phenomenon of inspection serum, the relative amount of Serum Antibody is determined with this.It is this to rely on artificial meat
Eye interpretation certainly exists error, especially when agglutination phenomenon is less obvious, the working experience of laboratory technician, eyes color discrimination and
The difference meeting interpretation of eyesight goes out different results.Therefore, people attempt with instrument come interpretation, and a kind of best selection is with light splitting
Photometer does the measurement of light transmittance to the liquid in agglutination test tube, obtains the data foundation of interpretation by light transmittance.But it is existing
Conventional agglutination test tube be in cylindrical type, cannot be used on spectrophotometer.If directly in the cuvette of spectrophotometer into
Then row agglutination test carries out determination of light transmittance, but since the flat-bottom structure of cuvette can be because of the rolling of liquid during interpretation
It moves and bottom agglutination precipitate is caused to rise, influence test result accuracy, or even cause serious error.If from completing to try
The conventional agglutination test tube tested takes supernatant to be fitted into the cuvette of spectrophotometer and is measured, on the one hand increases experiment step
Suddenly, link and experiment equipment increase the probability that accidental error occurs；It on the other hand is to take liquid process brighter to liquid perturbation
Aobvious, the uncertainty of test result is bigger.

There is a circular open, the lower part of square column type cavity is funnel shaped, and bell mouth connects with the circular open, two cavity phases
It is logical.
In the utility model, the thickness of the tube wall and be 1mm.
Further, the bore of the circular open is the 1/3~1/2 of spherical cavity diameter.
Further, the height of the test tube is 27mm, and the diameter of spherical cavity is 4mm, and the bore of circular open is 2mm,
The height of funnel is 5~8mm.
Further, the center of the spherical cavity is located on the middle line of the test tube, and the midpoint of circular open is located at examination
On the middle line of pipe.
Further, the middle line of test tube described in the center deviation of the spherical cavity, the edge of circular open is close to test tube
One side side wall.
Utility model has the advantages that 1, spherical cavity can store deposit in test tube, prevent due to mobile test tube
Caused liquid perturbation makes deposit rise, so as to reduce test error；2, it can be used on spectrophotometer, square column
Shape cavity portion is such as cuvette, and therefore, cloth disease tube agglutination test can carry out in the present invention, and can be by dividing
Light photometry interpretation experimental result, it is more objective, accurate；3, test result has a data foundation, and can long-term preservation, and overcome
The having different views for generating due to naked eyes interpretation.
