Abstract

The present invention provides an extraction cassette, which includes an extraction module. The extraction module includes an extraction module body, an expansion compartment, a reaction compartment,a filter, a collection compartment, a first waste-liquid compartment and a second waste-liquid compartment. The expansion compartment is formed on the extraction module body. The reaction compartmentincludes a reaction compartment inlet, a reaction compartment outlet and a reaction compartment notch, the expansion compartment is connected to the reaction compartment notch, and the reaction compartment notch is located between the reaction compartment inlet and the reaction compartment outlet. The filter is disposed in the reaction compartment and corresponding to the reaction compartment outlet. The collection compartment communicates with the reaction compartment outlet. The first waste-liquid compartment communicates with the reaction compartment outlet. The second waste-liquid compartment communicates with the reaction compartment outlet.

Description

technical field

[0001] Embodiments of the present invention relate to an extraction cassette, in particular to an extraction cassette with a liquid storage module. Background technique

[0002] The nucleic acid extraction module in the prior art mainly only provides the function of nucleic acid extraction, and does not have a waste liquid chamber design for accommodating waste liquid. Since the waste liquid may flow back and contaminate the filter membrane in the reaction chamber, in the prior art, the waste liquid chamber is not arranged adjacent to the collection chamber. Since the waste liquid chamber and the reaction chamber need to be arranged under different module kits, the size of the extraction cassette becomes very large, which not only takes up space, but also increases the cost.

[0003] There is also an all-in-one nucleic acid extraction module in the prior art, which utilizes magnetic bead extraction to extract nucleic acid, but the extraction efficiency and p...
