Digestion device for amino acid digestion experiment device

Abstract

The invention discloses a digestion device for an amino acid digestion experiment device, in particular to a laboratory instrument. Thedigestion device comprises a containing inner cylinder, a solid-liquid evenly-mixing mechanism and an outer sleeve, and the solid-liquid evenly-mixing mechanism comprises a fixed column,first elastic parts, anevenly-mixingcylinder and a storage mechanism. Through holes adaptive for penetration of the fixing column are arranged at the bottom end of the evenly-mixing cylinder, the first elastic parts are arranged on the outer side wall of the fixed column, one ends of the first elastic pieces are fixed to the bottom end of the containing inner cylinder, and the other ends of the elasticpieces are fixed to the bottom of the evenly-mixing cylinder; an opening and closing mechanism for air sealing or ventilating is arranged at the open end of the ventilating, the containing inner cylinderand the solid-liquid evenly-mixing mechanism are both arranged inside the outer sleeve, a joint communicating witha nitrogen ventilating tube is arranged on the side, back to the openend, of the outer sleeve, and correspondingly, a nitrogen outflow hole allowing nitrogento flow into the outer sleeve is arranged on the side wall of the containing inner cylinder, a gap for allowing the nitrogen to pass is arranged between the containing inner cylinder and the outer sleeve.The digestion device for the amino acid digestion experimentdevice has the advantage that homogenization can be realizedthrough shakingby experimenters.

Description

technical field [0001] The invention relates to a laboratory instrument, in particular to a digestion device for amino acid digestion experiments. Background technique [0002] When determining the elements in the sample, the sample needs to be digested. The role of digestion treatment is to destroy organic matter and dissolve particulate matter, and oxidize the analyte elements in various valence states into a single high valence state or convert them into easily decomposed inorganic compounds. [0003] Among them, in the experimental process of digesting amino acids, it is carried out in an oxygen-free environment. The usual practice of experimenters is to add samples and reagents into small glass tubes, and inject enough nitrogen gas into the glass tubes to exhaust the air, and then use alcohol torches to seal them. However, during the above experiment, when the sample powder is added to the inside of the glass tube, it is often difficult for the middle part of the samp...
