Description

Technical Field

[0001] The utility model relates to the technical field of digestion discs, in particular to a digestion disc with a condensation structure. Background Art

[0002] Iodine biochemical analysis is to detect the iodine in the sample. In the prior art, the sample is pre-treated in an independent heated digestion dish using an arsenic-cerium catalytic method and then placed in a spectrophotometer or biochemical analyzer to detect the iodine content.

[0003] When the existing heated digestion tray is in use, the test tube needs to be sealed and then the iodine element is analyzed. The applicant has applied for a relevant patent for an instrument for fully automatic iodine biochemical analysis. The present application is a further innovation of the already applied equipment. When using the fully automatic iodine biochemical analysis instrument, the test tube does not need to be sealed, and the test tube is left open for detection and analysis. This open method will cause the sample inside the test tube to volatilize when the test tube is heated, resulting in a reduction in the volume of the liquid in the sample, causing a large change in the concentration of the tested substance, affecting the accuracy of the detection.

[0004] Therefore, we propose a digestion tray with a condensation structure to solve the problem of sample volatilization inside the test tube caused by an open test tube. Utility Model Content

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Please refer to 1-2. An embodiment of the utility model provides: a digestion tray with a condensation structure, including a mounting bracket 1, a box body 2 is arranged above the mounting bracket 1, a bakelite insulation board layer 3 is arranged on the inner side of the box body 2, a heating film 4 is arranged between the bakelite insulation board layers 3 and located on the inner bottom surface of the box body 2, an aluminum alloy heat conducting plate 5 is arranged above the heating film 4, a test tube bottom shelf layer 6 is arranged above the aluminum alloy heat conducting plate 5, a test tube position control bracket 7 is arranged above the test tube bottom shelf layer 6, an insulation box body 8 is arranged above the test tube position control bracket 7, the test tube bottom shelf layer 6, the test tube position control bracket 7 and the insulation box body 8 are connected by a fixed copper column 9, and the insulation box body 8 A cold water pipe fixing frame 10 is fixedly provided on the upper surface, and a cold water pipe 11 is buckled on the cold water pipe fixing frame 10. A condenser aluminum plate 12 is provided above the cold water pipe 11. A temperature sensor 13 is fixedly connected to the side wall of the aluminum alloy heat conducting plate 5. The interior of the box body 2 is heated by the heating film 4, and the aluminum alloy heat conducting plate 5 is used to transfer heat to the test tube, so that the temperature inside the test tube rises, which acts on the liquid inside the test tube. The liquid in the test tube is affected by the temperature and begins to evaporate. At this time, the cold water inside the cold water pipe 11 reduces the temperature of the upper end of the test tube, so that the evaporated gas is hindered from evaporating when encountering cold air, thereby ensuring that the evaporation amount of the liquid in the test tube is reduced and the concentration of the liquid in the test tube is guaranteed.

[0017] The cold water pipe 11 is composed of a double-layer pipe connection. The cold water pipe 11 is provided with a water inlet and a water outlet. The water inlet and the water outlet pass through the box body 2 and are connected to an external circulating water pump. The circulating water pump circulates cold water in and out of the cold water pipe 11 to continuously reduce the temperature of the upper end of the test tube.

[0018] The heating film 4 and the temperature sensor 13 are both electrically connected to the control panel to facilitate heating and stability control.

[0019] The heat-insulating box body 8 is provided with a plurality of test tube holes, and the piping line of the cold water pipe 11 is arranged between the gaps between the test tube holes to prevent the piping line of the cold water pipe 11 from hindering the test tube from being inserted into the heat-insulating box body 8 .

[0020] The box body 2 is filled with heat-insulating cotton to ensure that the temperature inside the box body 2 is uniform, which is convenient for the test tube to be heated.

[0021] Working principle: When in use, insert the test tube into the condenser aluminum plate 12, and then start the heating film 4 through the control panel to heat the inside of the box body 2. After the liquid in the test tube is heated, relevant changes occur, and the liquid inside the test tube evaporates. At this time, the cold water pipe 11 located at the upper end of the test tube continuously circulates cold water, and transmits the temperature to the condenser aluminum plate 12, which blocks the evaporated liquid in the test tube inside the test tube, effectively reducing the evaporation of the liquid and ensuring the concentration of the liquid in the test tube. In this way, the data is more accurate during detection.
