Frequently Asked Questions
Are these microcentrifuge tubes certified free of contaminants?
Yes. Each lot is certified RNase-free, DNase-free, pyrogen-free, and ATP-free, making the tubes suitable for sensitive molecular biology and nucleic acid work.
What centrifugal force can these tubes withstand?
The polypropylene construction and locking snap cap are designed for routine microcentrifuge speeds. Confirm your rotor's rated g-force against the tube format before high-g protocols.
Can the tubes be autoclaved?
Polypropylene tubes tolerate standard autoclave cycles at 121 °C. Note that autoclaving voids the original lot certification for nuclease- and pyrogen-free status.
What is the pack quantity and how are they sold?
Tubes ship 500 per pack, priced per pack. The 0.5 mL, 1.5 mL, and 2.0 mL volumes are stocked under separate SKUs for individual ordering.
