Filter pipette tips, also known as aerosol barrier tips, prevent cross-contamination by using a hydrophobic filter (commonly polyethylene) to block aerosols, liquids, and vapors from entering the pipette shaft. They are essential for PCR, DNA/RNA work, and other sensitive assays, protecting both the sample and the pipette to ensure purity and accuracy.
Key Features and Uses
Protection
Acts as a barrier against aerosols, splashing, and liquid/vapor contamination.
Applications
- Molecular biology experiments
- Genomics workflows (PCR, NGS, qPCR)
- Virology studies
- Handling radioactive or biohazardous materials
Filter Material
Typically a porous polyethylene (PE) membrane.
Types
Available in a variety of sizes (10 µL to 1250 µL), sterile, RNase/DNase-free, and sometimes self-sealing or double-layered for additional safety.
Safety Space
Certain tips, such as Sartorius SafetySpace®, create an air gap between the liquid and the filter, preventing contamination even in cases of over-aspiration.
