Test Tubes with Attached Red Screw Cap, Polypropylene, 10 mL & 15 mL, 500/Case
The Globe Scientific Test Tube with Attached Red Screw Cap combines a durable polypropylene tube with a captive, leak-resistant closure that cannot be misplaced during high-throughput workflows. Ideal for sample storage, reagent aliquoting, and routine specimen transport, this tethered-cap design speeds processing while reducing cross-contamination and cap loss at the bench.

Frequently Asked Questions
Are these test tubes supplied sterile?
No. These polypropylene tubes are non-sterile as supplied. For applications requiring sterility, they should be autoclaved or sterilized in-house per your validated protocol.
Can the attached cap be fully removed?
The red screw cap is captive, designed to remain tethered to the tube to prevent loss and mix-ups during processing. It opens and closes via the screw thread while staying attached.
What is the unit of sale?
Both SKUs are sold per case of 500 tubes. The listed price is the per-case list price; tiered institutional pricing is available on request.
Are these tubes compatible with organic solvents?
Polypropylene offers excellent resistance to aqueous buffers, dilute acids, and dilute bases, but poor resistance to aromatic and chlorinated solvents. Review the chemical resistance table before use.
