Problems solved by technology

The separatory funnel is relatively large, and it can only be operated individually when oscillating and extracting. If multiple operations are required at the same time, an oscillator is required. When separating the liquid, the neck of the separatory funnel needs to be stuffed with glass wool or absorbent cotton. complex
[0003] Although this method has been used for many years, it has the following disadvantages: the separatory funnel is large in size and inconvenient to operate; the extraction and separation operation is complicated and requires more equipment; the amount of samples and reagents used is relatively large, etc.

Abstract

The invention discloses a treatment and application method of an extraction colorimetric bottle. The treatment and application method comprises the following steps: S1 baking the bottle body of the colorimetric bottle at a high temperature; S2 cooling the bottle body in the step S1 to room temperature, soaking the bottle body in 1 to 10% nitric acid, washing the bottle body with pure water, and drying the bottle body; S3 coating a circle of the inner wall of the bottle opening of the colorimetric bottle with silicone oil, and carrying out high-temperature baking on the colorimetric bottle, cooling to the room temperature and taking out for use; and S4 inspecting the colorimetric bottle treated in the step S3 for use after the colorimetric bottle is qualified. According to the method, the operation is simple, the colorimetric bottle treated by the method can be directly used for extraction, and spectrophotometric measurement can be directly carried out without liquid separation.

Description

technical field [0001] The invention relates to the technical field of processing colorimetric bottles, in particular to a processing and application method for extraction colorimetric bottles. Background technique [0002] In the measurement of certain substances, extraction spectrophotometry is required, that is, after the color reaction of the substance to be tested, it is extracted with a solvent, and then measured by spectrophotometry after liquid separation. This process requires extraction and separation with a separatory funnel. The separatory funnel is relatively large, and it can only be operated individually when oscillating and extracting. If multiple operations are required at the same time, an oscillator is required. When separating the liquid, the neck of the separatory funnel needs to be stuffed with glass wool or absorbent cotton. complex. [0003] Although this method has been used for many years, it has the following disadvantages: the separatory funnel ...
