Caplugs® Evergreen 1.6 mL Round Microcentrifuge Tubes with Tethered Caps, Polypropylene, Natural, 1000/Bag
Engineered for high-throughput benchwork, these 1.6 mL round microcentrifuge tubes with tethered caps deliver secure, one-handed closure for sample aliquoting, DNA/RNA storage, and routine centrifugation. Molded from natural polypropylene, each tube is non-sterile and autoclavable, supporting reagent prep, supernatant collection, and short-term specimen archiving across molecular biology and clinical research labs.

Frequently Asked Questions
Are these microcentrifuge tubes autoclavable?
Yes. Polypropylene tolerates standard 121°C steam autoclave cycles, so the tubes can be sterilized in-house when sterile conditions are required, since they ship non-sterile.
What is the benefit of the tethered cap?
An attached cap stays connected to the tube, enabling one-handed opening, reducing cap mix-ups, and preventing lost lids during sample handling and centrifugation.
What centrifugal force can these tubes withstand?
Polypropylene microcentrifuge tubes are suited to typical benchtop microcentrifuge speeds. Confirm the rated g-force for your specific rotor and balance tubes in opposing positions before each run.
Why is the natural (translucent) color useful?
Natural polypropylene is translucent, letting you visually check pellet size, sample volume, and phase separation without opening the tube.
