The main difference between pipette suction head with filter and without filter is reflected in its function and application scenario.

The suction head without filter element is an ordinary suction head, and its design and function are relatively simple, mainly for general pipetting operation.

The suction head with filter element, that is, the filter element suction head, is a more advanced design of pipette consumables. It adds a filter element to the tip of the suction head, which is usually made of medical-grade polypropylene and has an optimized aperture to ensure both good barrier effect and good ventilation. The main role of the filter element suction head is reflected in the following:

Ensure the safety of the experimental personnel: the filter cartridge suction head can reduce the spread of harmful products, and to a large extent ensure the personal safety of the operator. Especially in scenarios such as molecular biology experiments that are easy to produce aerosol pollution, the filter cartridge suction head can effectively prevent pipette pollution, and at the same time, it can better protect the safety of the experimenters in related experiments such as pathogen detection.
