Liquid Handling

Porex Pipette Tip, Automation, Serological and Cone Filters are the porous design solutions chosen by a broad spectrum of pipette and pipette tip manufacturers to help eliminate aerosol by-pass, sample carryover and the passage of aqueous based liquid from sample to equipment and instrumentation.

Pipette Tip Filters

POREX® Pipette Tip Filters are specifically designed to help eliminate aerosol bypass, sample carryover, and the passage of aqueous-based liquid to equipment and instrumentation. Inert, hydrophobic filter tip media solutions are designed for optimal fit, function, resilience, and porosity.

Robotic/Automation Filters

POREX® Robotic/Automation Filters meet the critical tolerance levels of today’s robotic pipette tips and automated liquid handling products. Maximum consistency in air flow, filter purity, and aerosol containment help instrument and consumable manufacturers deliver optimal pipetting and dispensing performance across a wide range of liquid volumes.

Pipette Cone Filters

POREX® Pipette Cone Filters are used at the pipette shaft base to help prevent fluid and liquid vapor contamination of samples and the pipette’s internal mechanisms and components. Inert, hydrophobic filter tip media solutions are design-optimized for fit, function, resilience, and porosity.

Serological Pipette Filters

POREX® Serological Pipette Filters help prevent trace carryover contamination caused by aerosols generated during sample aspiration. Porex filters are tested for clinical laboratory methodology compatibility by a third-party reference laboratory. They allow for work practice control of finished products by providing a precautionary measure that reduces the likelihood of exposure to bloodborne pathogens.

Serological Pipette Overview & Value Proposition

See for yourself why the POREX® Liquid Safe Filters exemplify the critical design and functional standards required for today’s serological products versus cotton and colored plug materials that allow liquid and aerosol bypass, that do not protect the pipette aid, and that have potential material residue, shed and methodology incompatibility.
