Globe Scientific 2mL Sterile Screw Cap Microtube with O-Ring Overview
The Globe Scientific 2mL Sterile Screw Cap Microtube with O-Ring is a polypropylene sample vessel built for secure storage and reliable sealing. An attached screw cap eliminates lost closures during high-volume processing, while the integrated O-ring delivers a leak-resistant seal for sensitive specimens. Each tube arrives sterile, ready for immediate use without additional preparation.
Designed to accept a color insert, this microtube supports rapid visual sample sorting across racks and freezer boxes. Laboratories handling large sample sets benefit from clear differentiation that reduces handling errors. The attached cap design keeps the closure tethered, streamlining single-handed operation at the bench.
Constructed from polypropylene (PP), the tube resists chemical attack and tolerates the temperature swings common in cold storage and centrifugation workflows. Sterile packaging supports applications where contamination control matters. Tubes ship 500 per bag, two bags per unit, for predictable inventory planning.

Laboratory Applications
Sterile screw cap microtubes serve sample archiving, aliquoting, and long-term storage in molecular biology and clinical labs. The O-ring seal helps protect volatile or precious samples during freezing, transport, and short centrifugation steps. Researchers rely on the attached cap to keep closures with each tube throughout repeated handling.
Color insert compatibility supports organized sample tracking in biobanking, PCR setup, and genomics workflows where many tubes move through a single run. Polypropylene construction suits aqueous buffers, nucleic acid suspensions, and reagent storage. Sterility makes these tubes appropriate for cell-based and contamination-sensitive protocols.
