Polypropylene Microtubes, 0.5–2 mL, Standard & Self-Standing, No Cap — 500/Pack
These Globe Scientific Polypropylene Microtubes offer reliable sample handling for PCR setup, centrifugation, and routine reagent storage. Molded from medical-grade polypropylene, each format withstands repeated thermal cycling and short high-speed spins. Self-standing options free up rack space at the bench, while traditional conical tubes drop into standard microcentrifuge rotors.

Frequently Asked Questions
Are these microtubes autoclavable?
Yes. The polypropylene construction tolerates standard autoclave cycles at 121°C, making the tubes suitable for sterilization prior to use in sensitive workflows.
Do the tubes include caps?
No. These microtubes are supplied without caps so labs can pair them with their preferred closure style or seal format. Order caps separately to match your application.
What is the difference between standard and self-standing tubes?
Standard conical tubes require a rack to stand upright, while self-standing tubes have a flat-base footprint that lets them rest on the benchtop independently for faster single-handed handling.
What temperatures can these tubes withstand?
Polypropylene microtubes are freezer-safe to -80°C and tolerate autoclaving at 121°C, covering routine cold storage and sterilization needs in molecular and clinical labs.
