Ultrasonic multi-channel self-reaction chemical coating instrument

Abstract

The invention discloses an ultrasonic multichannel self-reaction chemical coating instrument comprising a bracket, a water tank, an ultrasonic generator and a cup holder, wherein the bracket comprises an upright column and a cross arm arranged at the top of the upright column; the water tank is located at the bottom of the upright column; the ultrasonic generator is arranged in the water tank; and the cup holder comprises a longitudinal screw rod and a turnplate, the longitudinal screw rod is arranged on the cross arm of the bracket, the turnplate is connected to the bottom of the longitudinal screw rod and is provided with at least two vertically-perforated cup bases and at least two sample cups, each sample cup can be respectively placed on each cup base, and each sample cup comprises a cup body, an upper cover covering an opening in the top of the cup body and a lower sealing cover arranged on an opening in the bottom of the cup body in a sealing way; when each sample cup is placed on each cup base, the lower part of the cup body extends out of each cup base and is exposed below the turnplate, the lower part of the cup body can extend into the water tank by regulating the longitudinal screw rod, a coated substrate covers the top of the lower cover of the cup body in a sealing way, the top of the coated substrate is in contact with a solution in each sample cup, and the coated substrate is fastened between the lower sealing cover and the cup body.

Description

technical field [0001] The invention relates to the field of solution coating, in particular to an ultrasonic multi-channel self-reaction chemical coating instrument. Background technique [0002] Microwave digestion usually refers to the wet digestion that uses microwaves to heat the digestion solution (various acids, some lyes, and salts) and samples in a closed container to quickly dissolve various samples under high temperature and pressurized conditions (there are also open containers) Microwave digestion, not discussed). The two characteristics of closed container reaction and microwave heating determine its advantages of completeness, rapidity and low blank, but it inevitably brings the disadvantages of high pressure (possible hidden danger of overpressure) and small amount of digested sample. Contents of the invention [0003] One of the objectives of the embodiments of the present invention is to provide an ultrasonic multi-channel self-reaction chemical coating ...
