Abstract

This invention discloses a multifunctional microplastic filtration and collection device, belonging to the field of microplastic filtration and collection technology. The device includes a first filter cup, a cap threadedly connected to the first filter cup, and an inlet pipe on the cap. A second filter cup is located below the first filter cup, with an outlet pipe on its side wall. A heating and vibration module and a filtration and collection module are arranged between the first and second filter cups. This device can perform filtration, digestion, and flotation pretreatment of microplastics before collection, avoiding microplastic transfer loss and contamination. The first filter cup, second filter cup, heating and vibration module, and filtration and collection module are detachable, facilitating more thorough cleaning of the device's interior and preventing residual microplastic contamination from previous experiments from affecting microplastic detection results. The filtration and collection module is detachable for direct testing, offering convenience and speed.
