These 25ml glass centrifuge tubes have graduations and a leak-proof screw cap, and are typically made with a conical bottom for separating and storing samples. They're made from borosilicate 3.3 glass, which resists thermal shock and chemical corrosion.

Common Specifications

Most laboratory-grade 25ml glass centrifuge tubes share these standard features:

  • Dimensions: Typically about 24mm outer diameter and 98 to 120mm long.
  • Graduations: Usually white, screen-printed 1.0ml markings for easy volume reading.
  • Closure: A polypropylene (PP) or Bakelite screw cap, often with a rubber liner or sealing ring to prevent leaks during high-speed spinning.
  • Shape: A conical bottom is standard for forming a pellet, though round-bottom versions also exist for certain centrifuge rotors.

Specifications

  • Material: Clear 3.3 borosilicate glass
  • Neck: Screw cap
