Nuclear magnetic tube cleaning device

Abstract

The invention discloses a nuclear magnetic tube cleaning device, which comprises a cleaning bottle with a bottle cap, a circular rubber plate and a pressurization device, wherein the circular rubber plate and the pressurization device are positioned in the cleaning bottle; a cleaning fluid inlet is formed in the upper part of the sidewall of the cleaning bottle, and a waste fluid outlet is formed in the lower part of the sidewall of the cleaning bottle; at least one through hole is formed in the circular rubber plate; a ground circular hole is formed in the bottle cap; the pressurization device is closely connected with the cleaning bottle through the circular hole. The cleaning device is simple in structure, small in size, high in cleaning speed and time-saving, and has good effects, a cleaning process is simple, multiple nuclear magnetic tubes can be simultaneously cleaned at a time; materials used for the device are common devices in a laboratory, so that compared with a special cleaner, the cleaning device is low in cost, easy to assemble and convenient to use, can be assembled when being required to be used, and can be disassembled immediately after being used.

Description

technical field [0001] The invention belongs to a cleaning device for chemical experiment instruments, in particular to a nuclear magnetic tube cleaning device. Background technique [0002] As a means of analyzing substances, nuclear magnetic resonance technology has been rapidly developed and widely used because it can penetrate deep into the substance without destroying the sample, and has the advantages of rapidity, accuracy, and high resolution. It has penetrated from physics to chemistry, biology, geology, Disciplines such as medicine and materials have played a huge role in scientific research and production. But no matter what type of nuclear magnetic resonance is done, including hydrogen spectrum and carbon spectrum. Fluorine spectrum, phosphorus spectrum, etc. all need to put the sample into the NMR tube for detection. NMR tubes are generally made of quartz glass. Due to their small diameter, long tubes, thin tube walls, and fragility, it is difficult to clean th...

AI Technical Summary

Problems solved by technology

The nuclear magnetic tube is generally made of quartz glass. Due to its small diameter, long tube, thin tube wall and fragility, it has caused great difficulties in cleaning the nuclear magnetic tube.

At present, the commonly used cleaning methods are: 1. Manual cleaning, adding the cleaning solvent into the NMR tube and then cleaning it with a NMR tube brush, then throwing out the cleaning solvent and repeating it many times. This cleaning method is time-consuming and laborious, and it is easy to clean. Break the NMR tube or damage the NMR tube mouth, and the cleaning solvent will be thrown elsewhere, polluting the environment

Second, use a special NMR tube to clean the instrument, but these instruments are expensive and not suitable for ordinary laboratories
