2.0 mL Microcentrifuge Tube
Globe Scientific 111574 tubes hold 2.0 mL of sample in a graduated polypropylene body. The 500-piece pack comes in a stand-up zip-lock bag for bench organisation. Each tube is certified RNase, DNase and pyrogen free. They suit molecular biology, biochemistry and general lab workflows.
Sustained centrifugation performance
Polypropylene construction tolerates high g-forces without deformation during extended spins. Graduated markings remain legible after repeated autoclave cycles and chemical exposure. The snap-cap seal maintains integrity across long runs and temperature shifts. Certified purity eliminates nuclease contamination that could degrade nucleic acids over time.
Polypropylene tube limitations
Polypropylene softens above its melting range, so tubes cannot be used in boiling water baths or open-flame sterilisation. Snap caps are not rated for long-term cryogenic storage in liquid nitrogen vapour phase. The 2.0 mL volume caps the maximum sample per tube, requiring multiple tubes for larger aliquots. Zip-lock bag closure is not a sterile barrier once opened.

Questions about this item
Do the 2.0 mL polypropylene tubes generate heat or noise during continuous centrifugation runs?
The tubes are passive polypropylene vessels; they produce no heat or noise themselves — any temperature rise or sound comes from the centrifuge rotor and motor, not from the 500 tubes in the stand-up zip-lock bag.
What equipment must I already have to use these 2.0 mL microcentrifuge tubes?
You need a microcentrifuge that accepts 2.0 mL tubes, and standard laboratory pipettes or dispensers for filling; the tubes are graduated and certified RNase, DNase and pyrogen free, so no additional consumables are required for sterile workflows.
Will these 2.0 mL tubes fit in the older rotor adapters I already own?
The tubes follow the standard 2.0 mL microcentrifuge profile, so they seat in common rotor buckets and adapters designed for 2.0 mL vessels; the graduated markings and natural polypropylene material match legacy tube dimensions.
