Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic crushers, in particular to a single-channel non-contact ultrasonic crusher. Background Art

[0002] A non-contact ultrasonic disruptor is an instrument used for cell disruption, chromatin shearing, and DNA shearing. It is primarily used in experiments such as ChIP, ChIP-seq, and RNA-seq, but can also be used for routine cell disruption and protein extraction. It works by transferring ultrasonic energy to particles or cells in the sample, subjecting them to strong impact and shear forces, ultimately achieving sample disruption, dispersion, and mixing. Existing single-channel non-contact ultrasonic disruptors cause test tubes to vibrate under the action of ultrasound, which can easily cause instability or even damage, impacting the experiment.

[0011] Beneficial effects

[0012] The utility model provides a single-channel non-contact ultrasonic crusher. It has the following beneficial effects:

[0013] (1) The single-channel non-contact ultrasonic crusher can position the test tube by using the cooperation between the transducer base, the matching groove, the test tube nozzle positioning ring, the spring and the upper pressure cover, so as to ensure the accurate placement of the test tube. The upper pressure cover can then press the test tube tightly by using the elastic force of the spring, so that the test tube body is stably placed in the body. The elastic force of the spring can also be used to weaken the vibration of the test tube body, thereby improving the stability of the test tube body.

[0014] (2) The single-channel non-contact ultrasonic crusher closes the upper cover by the cooperation between the first magnetic sheet and the second magnetic sheet. The second magnetic sheet is adsorbed together with the first magnetic sheet, so that the upper cover is firmly closed, thereby ensuring the stability of the upper cover during the ultrasonic treatment process.
