The new range of liquid handling pipette tip filters from Porvair Sciences can block out aerosol and liquid contaminants. The company has used its proprietary Vyon porous plastics, so the new pipette tip filters are fully compliant with FDA, USP Class VI and European Pharmacopoeia statutory regulations as well as free from heavy metals. It says the combination of these ultra-clean materials, which have high levels of porosity, overcomes the traditional pipette tip challenges of reproducibility during high volume manufacturing and issues with cross-contamination. Porvair Sciences says it manufactures to tight tolerances with an exceptional edge finish and this ensures its pipette tip filters always provide an optimum fit into the customers’ pipette tip enabling labs to routinely achieve superior liquid handling and dispensing. Porvair pipette tip filters are produced using the latest inline technology for measuring air flow and thickness which delivers products which ensure the strength and reproducibility of liquid handling applications.
