Detachable clamshell type double-groove chromatographic cylinder capable of automatically controlling liquid

Abstract

The invention discloses a detachable clamshell type double-groove chromatographic cylinder capable of automatically controlling liquid. The detachable clamshell type double-groove chromatographic cylinder capable of automatically controlling liquid comprises a cylinder body, a cylinder cover, a TLC plate, an isolating plate, a one-way valve, isolating plate clamping grooves, a fixed clamp, a detachable hinge and a fixed clamping rail. The cylinder body of the chromatographic cylinder is formed by bonding five pieces of transparent organic glass; the isolating plate clamping grooves are formed in left, right and lower sides; the upper part of the cylinder body is connected with the cylinder cover through the detachable hinge; the lower part of the TLC plate is propped against the bottom of the front wall of the cylinder body; the upper part of the TLC plate is abutted against the back wall of the cylinder body; the left side and the right side of the TLC plate are clamped by fixed clamps; the isolating plate is arranged at the bottom of the cylinder body through the isolating plate clamping groove; a one-way valve is arranged at the right lower corner of the isolating plate; the fixed clamp straddles the top end of the isolating plate through the fixed clamp rail. The detachable clamshell type double-groove chromatographic cylinder capable of automatically controlling liquid can automatically control a developing agent in a back groove of the cylinder body to flow towards a front groove continuously, so that the personnel operation error can be reduced; external force interference can be avoided and the TLC plate can maintain stable; various samples can be tested simultaneously and the testing efficiency is improved; the detachable clamshell type cylinder cover facilitates the management of the chromatographic cylinder and is easy to mount and clean.

Description

technical field [0001] The invention relates to an automatic liquid control detachable flip-top double-slot chromatographic cylinder, which is mainly used as an experimental instrument for testing and analyzing materials by means of measuring their chemical or physical properties. Background technique [0002] At present, the chromatography cylinder commonly used in the laboratory, also known as the expansion cylinder, is generally composed of two parts: the cylinder body and the cylinder head. During the experiment, first inject the prepared developing agent (usually a mixed system of chloroform, methanol, water, etc.) into the chromatography cylinder, so that the developing agent completely submerges the bottom of the developing cylinder, cover the cylinder cover, and wait until the atmosphere in the cylinder is saturated. The experimenter opens the cylinder cover, grabs the thin-layer chromatography plate (TLC plate) that has been sampled with tweezers, and puts it into t...

Problems solved by technology

[0003] However, when the TLC plate used in the experiment is cut to a small size, during the experimental operation, when the TLC plate is placed in or taken out with tweezers, it is easy to cause operational errors, and the TLC plate is dumped into the chromatography tank; Or due to the violent vibration caused by the construction near the laboratory, or even the vibration of other experimenters accidentally colliding with the experimental platform or other experimental equipment on the same experimental platform, it is possible that the TLC plate in the chromatography tank will be dumped in the tank, thereby cause the experiment to fail

In addition, if too much developing agent is put into the TLC plate in the experiment, the developing agent will submerge the sample point, and some samples will be dissolved in the developing agent, so that the developing agent will be polluted and affect the test results; if the developing agent Putting in too little will make the Rf value of the sample too small, or some samples with close polarities cannot be completely separated, which will affect the experimenter's judgment on the result, and thus make the experiment useless. Therefore, there is an urgent need for a practical, easy-to-operate, Strong anti-interference, multi-functional chromatography tank to solve the above problems
