These 25mL graduated glass centrifuge tubes are typically designed with a conical bottom and a leak-proof screw cap for sample separation and storage. In South Africa, these are often supplied as Borosilicate 3.3 glass to ensure resistance to thermal shock and chemical corrosion.

Common Specifications

  • Most laboratory-grade 25mL glass centrifuge tubes share these standard features:
  • Dimensions: Typically ~24 mm in outer diameter and ~98–120 mm in length.
  • Graduation: Usually features white, screen-printed 1.0mL markings for easy volume reading.
  • Closure: Equipped with a polypropylene (PP) or Bakelite screw cap, often including a rubber liner or sealing ring to prevent leakage during high-speed spinning.
  • Shape: Conical bottom is standard for pellet formation, though round-bottom versions also exist for specific centrifuge rotors.
