FORTRESS® Pipette Tip Filters

Greater protection from aerosols and aspirated liquids

Our new FORTRESS^® Pipette Tip Filters offer a liquid-sealing barrier devoid of any contaminates or additives that can cause PCR, molecular, or analytical methodology and protocol issues.

Specifically designed to protect the sample and the pipetter from harmful aerosols generated during the pipetting process or from liquid aspirated into pipette tips, our filters:

Ensure purity–Non-leachable and extractable sample recovery is backed by the CERTIFIED PURE POREX^® program of independent analytical, clinical, and life science testing.
Protect sample integrity–Seals out aerosols and liquid contaminates while preventing cross-contamination and sample carryover.
Improve accuracy and precision–Design is optimized for maximum consistency in air flow, form, fit, and function across a broad spectrum of pipetting volumes

Automation and Robotic Pipette Tip Filters

Maximum consistency in airflow, filter purity, and aerosol containment

POREX^® Automation Certified Pipette Tip Filters are customized and optimized to meet the fit, air flow, and volume placement of your specific robotic and automated liquid-handling instruments, sample processors and dispensing systems.

To streamline laboratory operations and production, these automation and robotic pipette tip filters are backed by the CERTIFIED PURE POREX^® Program and:

POREX® Virtek™ IP-rated PTFE vents are designed to provide fast gas diffusion, while repelling dust, water and other contaminants. Specifically designed for electronic devices, our protection vents:

Maximize air flow–Delivers optimal dispensing and pipetting performance across a wide range of liquid volumes.
Prevent cross-contamination–Eliminates aerosol bypass and sample carryover.
Increase sample throughput–Provides tighter tolerance control for increasing laboratory workflow and reducing instrument downtime.

Pipette Cone Filters

Stronger protection from contamination for pipetters and samples

POREX^® Pipette Cone Filters help prevent samples, and the pipette’s internal mechanisms and components, from fluid and liquid vapor contamination.

Used at the pipette shaft base, these inert, hydrophobic filter tips are optimized for fit, function, resilience, and porosity. Backed by the CERTIFIED PURE POREX^® Program, our filter tips:

Protect pipetter’s internal components–Serves as a final interferent barrier.
Prevent contamination–Protects against aerosols and sample cross-contamination.
Prolongs product lifetime–Reduces chance for contamination which lowers the need for pipetter maintenance

Serological Pipet Filters

Higher performance and aerosol protection with customized solutions

Protect serological pipet and samples from contamination, fast draw uptake, and unintentional sample expulsion with a family of customizable aerosol barrier filters.

Tailored to meet the correct fit, air flow, and volume placement within your pipettes, our serological filters protect lab personnel, maintain productivity and:

Safeguard samples–Use aerosol barrier filters versus use of cotton or colored plugs.
Improve quality and safety–Reduces fast draw sample uptake and stop samples from exiting the pipette.
Minimize accidental exposure–Decreases exposure to hazardous substances and the need for internal syringe filters.

ESR Filters

The Erythrocyte Sedimentation Rate (ESR) determination is a commonly performed laboratory test used to screen for the possible presence of bodily disease or abnormality.

The test measures the distance red cells have fallen after separating from the plasma in a vertical ESR pipette and offers simple, safe, economical and highly-accurate Westergren ESR determinations.

POREX® ESR Tube Filter Media is designed to draw blood up to the zero mark and act as a protective barrier that stops hazardous substances from escaping through the top of the pipette.
