Microcentrifuge Tubes, Polypropylene, Attached Snap Cap, Graduated — 1.5 & 2.0 mL, Natural, 500/Pack
The Globe Scientific Microcentrifuge Tubes are molded from natural polypropylene with an attached snap cap and printed graduations, supporting routine sample aliquoting, DNA/RNA extraction prep, and short-spin pelleting at the bench. Each tube secures contents in a single one-handed motion, reducing cross-contamination during high-throughput pipetting workflows.

Frequently Asked Questions
Are these microcentrifuge tubes autoclavable?
Polypropylene tolerates standard autoclave cycles at 121°C. Place tubes with caps open in a vented container to allow steam penetration and even cooling, then verify dimensional integrity before reuse.
What centrifugal force can these tubes withstand?
Polypropylene microcentrifuge tubes in this format are generally rated for typical bench-top RCF used in microcentrifuges. Confirm the maximum g-force in the product instructions and match your rotor specifications before high-speed runs.
Are the tubes sterile or certified RNase/DNase-free?
These tubes are supplied non-sterile. For nucleic acid work requiring certified lots, contact us to confirm availability of validated alternatives within the Globe Scientific range.
How many tubes are in each pack and how are they billed?
Each pack contains 500 tubes, and listed prices are per pack. Lot numbers on every pack support documentation requirements for accredited and regulated laboratories.
