Self-Sealing Filter Tips for Disposable ESR Pipettes

BLINEX PORSELFTM Self-Sealing Filter Tips are precision-engineered porous polymer filter elements designed specifically for disposable ESR (Erythrocyte Sedimentation Rate) pipettes.
These filters automatically seal upon liquid contact, preventing blood backflow, leakage, and contamination—ensuring operator safety and test accuracy.

Manufactured using controlled-porosity sintered polymers, BLINEX ESR filter tips deliver consistent airflow, instant liquid shut-off, and high chemical compatibility, making them ideal for routine and high-volume diagnostic laboratories.
