Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in Figures 1 to 5, the utility model provides a kind of digestion instrument for the wet digesting processing of fluid sample,
Including constant temperature digestion instrument 1 and the digestion utensil of multiple closings 2, constant temperature digestion instrument 1 is equipped with multiple bottoming holes 11, digestion utensil 2
Vertically it is set in bottoming hole 11.Using the technical solution of the utility model, using constant temperature digestion instrument and special disappear respectively
The heating plate and flask that solution vessel substitution uses in the prior art keep constant the wet digesting temperature in the process of urine sample, disappear
The sample changed in pipe is heated evenly, and is maintained constant temperature digestion, is made Volatile Elements in sample will not be due to digest tube hot-spot
And volatilization loss, the stability of testing result is improved, and digest temperature to be set as needed, model is adjusted in temperature
Enclose significantly, controllability is strong, may be not only suitable for be urine sample digestion process, be equally applicable to food, human organ and liquid
The digestion process of body sample and environmental sample etc., meanwhile, one time multiple digestion utensils can be used in digestion process, improve digestion
