Embodiment 1

[0018] An ultra-high-efficiency concentration device, such as figure 1 As shown, it includes a container 1 and a plug body 2 connected to the top of the container 1 .

[0019] Specifically, the section of the plug body 2 is an inverted trapezoidal shape, and the angle between the waist and the bottom is 65-85°, preferably 82°, which is more reliable and stable in connection with the container, and has excellent sealing performance.

[0020] The central position of the plug body is penetrated into an air suction port 21, which can exhaust the inside of the container 1 at the central position.

[0021] The container 1 is a test tube container, which cooperates with the metal bath beads during the concentration process to heat or cool the solvent, which is suitable for different temperature requirements of the samples.

[0022] In the way of air intake, a spiral air intake channel 22 is provided at the circumferential position of the plug body 2 .

[0023] The helical air inlet...

Abstract

The invention discloses a ultra-efficient concentration device, which comprises a container and a plug body connected with the top of the container, an extraction opening is formed in the center of the plug body in a penetrating mode, and a spiral air inlet channel is formed in the circumferential position of the plug body. The device is suitable for concentration of common solvents, the concentration efficiency of the common solvents is greatly improved, and the problem that high-boiling-point solvents are difficult to concentrate and samples are difficult to recover is solved.

Description

technical field [0001] The invention relates to the field of concentration, in particular to an ultra-high-efficiency concentration device. Background technique [0002] More than 90% of the samples in the laboratory need to be dissolved in a suitable solvent for inspection and testing, and there are certain requirements for the concentration, which requires high-efficiency concentration equipment [0003] At present, when the solvent is concentrated in the inspection and testing industry, the heating method of the solvent is a water bath or a metal bath, and appropriate heating is added with air or nitrogen blowing, and the gas evaporated from the solvent is condensed and recovered. [0004] However, it is difficult to concentrate high-boiling-point solvents such as universal solvents DMSO / DMF / NMP in the laboratory, and current concentration equipment such as rotary evaporators, nitrogen blowers, and freeze dryers have certain limitations in concentration efficiency, and ca...
