Efficient termovap sample concentrator

Abstract

The invention discloses an efficient termovap sample concentrator. The efficient termovap sample concentrator comprises a worktable, a plurality of heating discs, test tube discs which correspond to the heating discs, a needle blowing disc and a rocker arm, wherein the rocker arm is fixed at the center of the worktable; the heating discs are arranged on the worktable in an array along the circumference by taking a fixed point of the rocker arms as the circle center; the needle blowing disc is arranged just above any heating disc through the rocker arm; the needle blowing disc can do circular motion by taking the rocker arm as the circle center. The efficient termovap sample concentrator is simple in structure and meets the requirements of large-batch rapid detection.

Description

technical field [0001] The application relates to the technical field of rapid detection of food quality, in particular to a high-efficiency nitrogen blowing instrument. Background technique [0002] Nitrogen blowing instrument is also called nitrogen drying instrument, automatic fast concentrator, etc., by blowing nitrogen rapidly, continuously, and controllably to the surface of the heated sample, the water in the sample to be treated can be evaporated and separated rapidly, so as to realize the At the same time, the instrument can maintain the purity of the sample, so as to achieve the effect of rapid separation and purification. The nitrogen blowing instrument is easy to operate, so it has been widely used, but the capacity of the test tube plate of the existing nitrogen blowing instrument is limited. It can only process limited samples, and when changing samples, it can only change the test tubes one by one. The work efficiency is low and it cannot meet the testing need...

Problems solved by technology

[0002] Nitrogen blowing instrument is also called nitrogen drying instrument, automatic fast concentrator, etc., by blowing nitrogen rapidly, continuously, and controllably to the surface of the heated sample, the water in the sample to be treated can be evaporated and separated rapidly, so as to realize the At the same time, the instrument can maintain the purity of the sample, so as to achieve the effect of rapid separation and purification. The nitrogen blowing instrument is easy to operate, so it has been widely used, but the capacity of the test tube plate of the existing nitrogen blowing instrument is limited. Only a limited number of samples can be processed, and when changing samples, the test tubes can only be replaced one by one. The work efficiency is low, and it cannot meet the testing needs of large quantities.
