- Safelock cap
- Sterile or non-sterile
- Three capacities
Graduated microcentrifuge tubes employ the Safelock cap, an advanced locking system for safe centrifuging, boiling, freezing, incubation or storage of samples. The cap snaps close and the lock slides into place in one simple hand operation.
The larger rounder cap design provides greater thumb contact while its smooth surface reduces the possibility of ripped or punctured gloves.
Microcentrifuge tubes come in three capacities: 0.6 mL tubes are rated at 30,000 x g, 1.5 mL tubes are rated at 24,000 x g and 2.0 mL tubes are rated at 25,000 x g. Tubes come bulk packed in bags of 500 or 1,000 or individually wrapped in packs of 500.
