Abstract
An isolation device includes an isolation chip, a pressing assembly, two ultrasonic generators, a differential pressure driving system, a frequency conversion module, and a controller. The isolation chip includes a sample reservoir, a first chamber, and a second chamber. The pressing assembly drives the two ultrasonic generators to move towards the isolation chip to make in contact with the first and second chambers. The frequency conversion module controls the differential pressure driving system to generate a negative pressure in the first and second chambers alternately. The controller controls the two ultrasonic generators to generate two ultrasonic waves when negative pressures are cancelled in the first and second chambers. An isolation method is also disclosed.
