(4) packing of urine：It will be dispensed into urine holding bottle per a urine using the glass pipette and suction ball handled well
In；
(5) storage of urine：The urine dispensed is stored at once in -20 DEG C of refrigerator store it is spare.
Step (1) the potassium bichromate washing lotion is according to 20g potassium bichromates, the 500ml concentrated sulfuric acids, the ratio of the distilled water of 40ml
To configure.
Step (1) the Muffle furnace drying temperature is 400 DEG C, is toasted 2 hours, and step (2) baking oven drying temperature is 80 DEG C,
Baking 1 hour.
Baked glass equipment and cup lid are threaded together after the completion of the step (2), and using masking foil by its
It packs spare.
The potassium bichromate, dichloromethane and the concentrated sulfuric acid are chromatographically pure.
The beneficial effects of the utility model are：The equipment and materials that can be in direct contact with urine in the utility model be glass and
Metal, and using potassium bichromate washing lotion glass is handled, metal cover is handled using dichloromethane solution.It compares
The Medical urine cup of existing plastic material, the utility model greatly reduce the reasons for its use in collecting urine and pollute.And
And the urine collected in the utility model back is divided in three urine holding bottles, avoids urine and oxygen in post analysis
Frequent contact, also avoid the multigelation of urine in the analytic process in later stage.
