A hand-held portable nuclear magnetic resonance sample tube high-pressure cleaner

Abstract

The invention discloses a handheld portable nuclear magnetic resonance sample tube high-pressure cleaning device, and belongs to the technical field of a high-pressure cleaning device. The handheld portable nuclear magnetic resonance sample tube high-pressure cleaning device comprises a washing spray head and a machine body, wherein the tail of the washing spray head is inserted into an adapter; the adapter is connected to a variable-diameter screw which is connected to the machine body by a connecting screw; a connecting joint, an internal connecting pipe and a miniature pressure water pump are arranged in the machine body; one end of the connecting joint is connected to the connecting screw; and the other end of the connecting joint is connected to a pipeline; the other end of the pipeline is connected to one end of the miniature pressure water pump; the other end of the miniature pressure water pump is connected to an external connecting pipe; the other end of the external connecting pipe is connected to a water source or an air source; the machine body is provided with a handle; a power supply is arranged in the middle of the handle; one end of a power line No.1 and one end of a power line No.2 are connected to the power supply. The handheld portable nuclear magnetic resonance sample tube high-pressure cleaning device is suitable for sample tubes with various diameters, is convenient to operate , has no special requirements on operation conditions and has strong universality; and as water serves a cleaning medium, the handheld portable nuclear magnetic resonance sample tube high-pressure cleaning device is green and environmentally-friendly and has powerful generalizability.

Description

technical field [0001] The invention belongs to the technical field of high-pressure cleaning devices, and in particular relates to a hand-held portable high-pressure cleaner for nuclear magnetic resonance sample tubes. Background technique [0002] At present, large-scale scientific research instruments are rapidly popularized in national universities, research institutes and high-tech enterprises. For example, high-resolution nuclear magnetic resonance technology is developing rapidly. They are widely used in chemistry, biology, materials, electronics, medicine, food, pharmacy and pathology play an irreplaceable role. In the past two decades, liquid high-resolution NMR spectrometers have been widely used in universities, scientific research institutes, customs, drug regulatory departments, pharmaceutical companies and related enterprises and institutions. A large number of NMR sample tubes need to be cleaned after testing. Due to the small inner diameter, long length and ...

Problems solved by technology

The advantage of this method is that there is no damage to the NMR sample tube and the cleaning speed is fast; the disadvantage is that the cleaning of stubborn stains is not thorough, and the amount of rinsing solvent is very large

At present, there are relatively few types of NMR sample tube cleaners on the market, and those that can be seen in the domestic market are basically designed according to the principle of vacuum negative pressure. The disadvantages of this cleaner are obvious as mentioned above. Promotion is not good
