Embodiment Construction

[0010] In the accompanying drawings, the magnetic box (12) is a sealed plastic bottom bracket with a built-in magnet (10) inside. The test tube rack (1) is rectangular and has four supporting legs (6). There are two rows of test tube jacks (2) on the test tube rack (1) for inserting test tubes (3). There is one on each side of the test tube rack (1). The test tube rack hook (8), the four supporting legs (6) of the test tube rack (1) can be inserted into the box socket (7), and at the same time, the test tube rack hook (8) is inserted into the slot (9) at the bottom of the box And with the magnetic casing (12) firm sleeve together. Push the locking end (5) of the card plate (4) to lock the test tube (3), and the built-in magnet (10) in the magnetic box (12) will bind the DNA (or protein) in the test tube (3) to the magnetic reagent Adsorbed on the test tube wall, press the safety button (11) on the test tube rack (1), and then push the unlocking end (13) of the clamping plate ...

Abstract

This invention discloses a magnetic card extractor for extracting DNA, RNA or protein. The magnetic card extractor comprises a test tube rack and a magnetic box. The both sides of the test tube rack are tightly locked on the magnetic box by clasps and the lock on the card, so that the test tube in the hole of the upside-down extractor cannot fall. DNA, RNA or protein combined with the magnetic reagent in the test tube is adsorbed to the test tube wall by the magnetic force, so that DNA, RNA or protein is left in the test tube after pouring the waste liquid in the experiment.

Description

Technical field [0001] The invention relates to a device for extracting DNA (or RNA or protein) from biological samples simply and quickly, and relates to the field of biochemical experiments. Background technique [0002] At present, when extracting DNA (or RNA or protein), it is necessary to add a variety of different reagents to the sample. Therefore, it is necessary to perform sample precipitation, filtration, and supernatant extraction operations many times during the experiment. Traditional methods are used for this. This experiment can only be performed with a single tube, and there are problems such as long time consumption, cumbersome operation and low extraction purity. Contents of the invention [0003] In order to overcome the shortcomings of traditional DNA (or RNA or protein) extraction operation time-consuming, complicated operation and low extraction purity, the present invention provides a DNA (or RNA or protein) extractor, the DNA (or RNA or protein) extr...
