Specially engineered to fit standard taper joints and tubes. Manufactured under white room conditions for extreme cleanliness. Made of a more dense rubber, low extractables and a better fit (50% to 80% on joints) these septa are much less likely to fail in the presence of solvents.

For use in removing fibrin and macro particles from serum to prevent line clogging. Users insert the 16 mm flange into the evacuated blood tube and push downward. Graduated barrel tells exactly how much liquid has been filtered. Wide-body style prevents sample probes from hitting side walls.
