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.
