It's hard to believe that simple molded plastic disposable suction heads are the bread and butter of molecular biology, chemistry and medicine. Yes, we're talking about pipette suction. These suction heads create a reliable and accurate pipetting system. Pipette suction heads are divided into three different types, including unsterilized, pre-sterilized and filter cartridge suction heads.

Filter pipette suction (filter cartridge suction) is designed to prevent the formation of aerosols. Aerosols are small liquid or solid particles in the air. These particles can actually stay in the air for a long time and can be inhaled. Even worse, 65 percent of laboratory infections are caused by aerosols, usually by inhaling them. Filter pipette heads help reduce the risk of aerosol formation in the laboratory. They also protect pipette shafts from contamination and reduce the risk of cross-contamination. These pipette suction heads are commonly used in contamination sensitive applications, such as forensics and clinical diagnostics.
