Full-automatic amino acid hydrolysis instrument

Abstract

The invention discloses a full-automatic amino acid hydrolysis instrument which comprises a shell and a heating cavity, the heating cavity is arranged above the shell, a vacuum switching block is arranged in the center of the interior of the heating cavity, an air support base is arranged above the heating cavity, and a proximity switch is arranged below the heating cavity. A control touch screen is arranged on the left side of the heating cavity, an upper cover is arranged at the rear end of the shell, and a hinge is arranged at the joint of the upper cover and the shell. According to the multi-guarantee design of heating power and temperature control, sufficient heating is guaranteed, and fire disasters are avoided; the equipment is provided with a precise full-automatic vacuumizing and nitrogen filling mechanism, so that oxygen can be fully discharged, and a sample can be fully hydrolyzed. Due to the closed-loop pipeline design, hydrolysis can be carried out in a closed space, so that the safety of a sample is guaranteed, and the leakage risk of corrosive sample liquid and gas is reduced. Temperature-controlled vacuum drying is achieved, transfer concentration treatment is not needed, the hydrolysis process is completed in one step, and samples are safer and more efficient.

Description

technical field [0001] The invention relates to the technical field of protein amino acid hydrolysis, in particular to an automatic amino acid hydrolysis apparatus. Background technique [0002] At present, there are three common hydrolysis methods and equipment: 1. Add the samples and reagents to be tested into the hydrolysis tube, fill with nitrogen, screw on the cover, put it into the oven for heating, and after hydrolysis, use a nitrogen blowing concentrator or parallel evaporation 2. The special hydrolysis tube is equipped with a gas valve and a gas interface. The gas tube is connected to a vacuum pump and a nitrogen cylinder respectively, and the air valve is controlled to prevent air from flowing into the hydrolysis tube, and then put into an oven for heating and hydrolysis. Then, use a nitrogen blowing concentrator or a parallel evaporator to concentrate or evaporate to dryness under reduced pressure; 3. Use an alcohol torch to sinter the hydrolysis tube, and at the ...
