Detachable one-mouth bottle

Abstract

The invention discloses a detachable one-mouth bottle, comprising a one-mouth bottle body; the one-mouth bottle body consists of a one-mouth bottle body upper part and a one-mouth bottle body lower part; external threads on the bottom end of the one-mouth bottle body upper part and internal threads on the top end of the one-mouth bottle body lower part are in spiral connection, a first fastening washer is arranged between the bottom of the external threads of the one-mouth bottle body upper part and the top end of the one-mouth bottle body lower part, a second fastening washer is arranged between the top end of the external threads of the one-mouth bottle body upper part and the bottom of the internal threads of the one-mouth bottle body lower part, a 2 / 3 scale line and a 1 / 3 scale line are arranged on the inner wall of the one-mouth bottle body, and the 2 / 3 scale line is located above the 1 / 3 scale line; a bottle mouth on the top of the one-mouth bottle body is tightly connected to a ground bottle stopper; and three glass supports are equidistantly fixed on the bottom of the one-mouth bottle body. The detachable one-mouth bottle realizes one purpose by one article, not only can serve as a one-mouth bottle but also can serve as a three-mouth bottle and a four-mouth bottle, and makes up the defect of a single function of the traditional one-mouth bottle.

Description

Technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a detachable single-mouth bottle. Background technique [0002] At present, many products need to use a rotary steam separator to separate the solvent part of the product, and the solute (that is, the effective product) sticks to the inner wall of the single-neck bottle, and the solid product needs to be scraped out. It is deep but the mouth of the bottle is small, so it is very troublesome to scrape the effective product directly from the mouth of the bottle, and part of the effective product cannot be scraped out, resulting in a decrease in the effective yield of the reaction. Since the small spatula is inconvenient to use in the single-neck bottle, it is easy to scratch the inner wall of the single-neck bottle in the process of scraping the product. Many products (especially medicines) must not come into contact with water during the configuration process, and each ...

Problems solved by technology

[0002] At present, many products need to use a rotary evaporator to separate the solvent part of the product, and the solute (that is, the effective product) sticks to the inner wall of the one-mouth bottle, and the solid product needs to be scraped out, and because the bottle body of the one-mouth bottle is large and It is deep but the mouth of the bottle is small, so it is very troublesome to scrape the effective product directly from the mouth of the bottle, and some effective products cannot be scraped out, resulting in a decrease in the effective yield of the reaction

Because the small spatula is inconvenient to use in the one-mouth bottle, it is easy to scratch the inner wall of the one-mouth bottle in the process of scraping the product

Many products (especially medicines) must not be exposed to water during the preparation process, and the experimental supplies need to be washed before each experiment. For single-mouth bottles with large and deep bottles but small mouths, if you use a hair dryer It takes a long time to dry the moisture from the mouth of the bottle, which is not conducive to the use of the bottle
