Description

Technical Field

[0001] The utility model belongs to the technical field of laboratory equipment, and in particular relates to an oscillating device for detection. Background Art

[0002] In the testing of drugs and foods, it is often necessary to pre-treat the samples to be tested to obtain a uniform solution, and then test the solution to facilitate the test and ensure the accuracy and uniformity of the test results. In the pre-treatment of samples, shaking is a common operation. Shaking the sample liquid can promote dissolution or reaction and make the liquid uniform. For example, patent CN109580848A disclosed on April 5, 2019, a method for simultaneously determining multiple pesticide residues in honey, comprising the following steps: (1) adding a honey sample to a stoppered centrifuge tube, adding water and mixing evenly, then adding acetonitrile, mixing evenly, and then adding a mixed powder of anhydrous magnesium sulfate and anhydrous sodium acetate, mixing evenly, and then cooling in an ice bath for 8 to 10 minutes, centrifuging at a speed of 3500 to 4000 r / min for 5 to 7 minutes, and taking the supernatant; (2) adding the supernatant of step (1) to a dispersed solid phase extraction purification tube containing purification material, vortex mixing, shaking for 3 to 5 minutes, and centrifuging at a speed of 3500 to 4000 r / min for 5 to 8 minutes to obtain an extract; (3) filtering the extract of step (2) with a filter membrane, taking the filtrate and testing it on a machine.

[0003] Patent CN114733410A disclosed a test tube oscillation device for drug testing on 2022-07-12, and its structure includes an oscillation host, a rocker, and a support foot. The rocker is arranged on the outer side of the left end of the oscillation host, and the bottom of the oscillation host is fixed to the upper end of the support foot, and the cam on the linkage rotating rod is rotated to repeatedly push up and sink the top plate, and oscillate eight test tubes synchronously to improve the oscillation efficiency. At the same time, the bottom of the test tube contacts the top plate, and the telescopic hose is squeezed and contracted, so that the suction cup and the bottom of the test tube are vacuum adsorbed to avoid the bottom of the test tube from falling off from the top plate during the oscillation process, and the effect of oscillation at the bottom of the test tube is improved. The sliding shaft is elastically guided and slid inside the slide rail to ensure that the gravity ball is vertically offset by gravity, so that the gravity ball elastically squeezes the upper end of the test tube by gravity, so that the test tube is vibrated up and down, and the oscillation effect of the upper end of the test tube is improved. The device oscillates the test tube up and down, and the single oscillation method makes the oscillation effect poor, and the oscillation time required is long. For some sample liquids, such as traditional Chinese medicine liquid rich in saponins, abundant foam may be generated during shaking. At this time, the sample liquid can easily break the test tube stopper and spill out from the test tube mouth. Utility Model Content
