Globe Scientific Filter Pipette Tips, Low-Retention Polypropylene, Sterile Racked — 0.1–1250 µL, 960/Case
The Globe Scientific Filter Pipette Tips deliver aerosol-barrier protection and low-retention surfaces across a full 0.1–1250 µL range, making them ready for PCR and qPCR master-mix assembly, nucleic acid extraction, and trace-sensitive serial dilutions. Molded from virgin polypropylene with a self-sealing hydrophobic filter, each tip guards pipette shafts from contamination while improving recovery of viscous or precious samples.

Frequently Asked Questions
Are these filter tips certified RNase- and DNase-free?
Yes. Globe Scientific manufactures these tips to be sterile and certified free of RNase, DNase, and pyrogens, making them suitable for sensitive molecular biology workflows.
What does "low retention" mean for sample recovery?
The polypropylene surface is treated to minimize liquid adhesion, so more of each aliquot is dispensed. This improves accuracy with viscous, surfactant-containing, or precious low-volume samples.
Will these barrier tips fit my brand of pipettor?
The range includes universal-fit geometries that seat on most standard single- and multichannel pipettes. Confirm volume and shaft compatibility against your instrument before ordering.
What is the difference between standard and extended-length tips?
Extended-length variants (10 µL and 1250 µL) reach deeper into tall tubes, conical vessels, and narrow flasks, reducing the risk of barrel contact during aspiration.
