About this item

• Material & clarity: virgin polypropylene (PP), optically clear for direct sample inspection; chemically inert for broad reagent compatibility
  
• Graduation markings: precision-molded graduations for fast, repeatable volume verification during pipetting and sample prep
  
• Seal integrity: flat-top snap-cap design providing a hermetic closure that resists evaporation and prevents accidental opening during vortexing
  
• Centrifugal & thermal performance: validated for centrifugation up to 5,000 RPM; heat-resistant to 80 °C for thermal incubations and dry-bath applications without structural deformation
  
• Compatibility & formats: standardized dimensions for major microcentrifuge rotors and thermal blocks; flat cap surface for labeling. Available: 0.2 ml (2.1 cm, 1000 pcs/pack), 0.5 ml (3.2 cm, 500 pcs/pack), 1.5 ml (4.3 cm, 500 pcs/pack), 2.0 ml (4.2 cm, 200 pcs/pack)
