Centrifuge tubes are specialized laboratory containers used to separate, isolate, and store components of a liquid mixture by spinning them at high speeds. This model is manufactured from polypropylene with a leak proof HDPE Blue Screw Cap is Free Standing or skirted, Individual packing, EO Sterile and has white graduations.

When a tube is spun in a centrifuge, the resulting centrifugal force separates substances based on their density:

  • Pelleting: Denser materials (like cells or solid particles) are forced to the bottom, forming a "pellet".
  • Supernatant: The lighter, liquid portion remains on top and is called the "supernatant". 

Key Benefits and Features:

  • Design: These tubes feature a self-standing (or skirted) base, allowing them to remain upright on a lab bench without a rack.
  • Printing: White graduation and white writing area
  • Sterility: They are sterilized using Ethylene Oxide (EO) gas and are individually packed to prevent cross-contamination before use.
  • Material: Made from polypropylene (PP), which provides high clarity for sample visibility and resistance to chemical corrosion.
  • Closure: A blue screw cap (HDPE - High Density Polyethylene) ensures a leak-proof seal during high-speed centrifugation and transport.
  • Graduation: The tubes are printed with clear, accurate volume markings (graduations) to allow for precise measurement.

Common Applications

  • Centrifugation: Used to separate components of a sample (such as blood or cell cultures) by rapidly rotating them around a fixed axis.
  • Sample Storage: Ideal for long-term storage of liquids, powders, or solid samples due to their secure, leak-resistant caps.
  • Transport: The secure screw cap makes them suitable for safely transporting biological or chemical substances.
