Centrifuge Tubes
Centrifuge tubes are high-strength lab containers designed for safe and efficient sample separation during centrifugation. Made from polypropylene (PP) or polycarbonate (PC), they are chemically resistant, autoclavable, and available in a range of sizes (1.5 mL to 50 mL).
With leak-proof caps, graduated markings, and conical bottoms, these tubes are ideal for clinical, molecular biology, biochemistry, and pharmaceutical applications.
Centrifuge Tubes – FAQs:
Q1. What are Centrifuge Tubes?
Centrifuge tubes are laboratory containers designed to hold biological samples, chemicals, or solutions during centrifugation. They are made to withstand high centrifugal forces in equipment such as microcentrifuges and high-speed centrifuges.
Q2. What are Centrifuge Tubes used for?
Centrifuge tubes are used for:
- Separating biological components (DNA, RNA, proteins, blood cells).
- Pelleting cells and microorganisms.
- Purification of chemical compounds.
- Sample storage and preparation.
- Clinical diagnostics and molecular biology research.
Q3. What materials are Centrifuge Tubes made of?
- Polypropylene (PP) – autoclavable, chemical resistant, widely used.
- Polycarbonate (PC) – high clarity, strong, but limited chemical resistance.
- Polystyrene (PS) – economical, transparent, not suitable for high-speed centrifugation.
Q4. What types of Centrifuge Tubes are available?
- Conical Centrifuge Tubes (15 mL, 50 mL) – most common, tapered bottom for pelleting.
- Round Bottom Centrifuge Tubes – stable, used for gentle centrifugation.
- Screw Cap Centrifuge Tubes – leak-proof, safe for storage and transport.
- Sterile Centrifuge Tubes – individually packed for microbiology & cell culture.
- Disposable & Reusable Centrifuge Tubes – depending on lab requirement.
Q5. What sizes do Centrifuge Tubes come in?
- Microcentrifuge Tubes – 0.2 mL, 0.5 mL, 1.5 mL, 2.0 mL.
- Conical Centrifuge Tubes – 15 mL, 50 mL.
- Large Volume Tubes – up to 250 mL (for high-capacity centrifuges).
Q6. Are Centrifuge Tubes autoclavable?
- PP Centrifuge Tubes – Yes ✅, autoclavable at 121°C.
- PC & PS Tubes – Not recommended for repeated autoclaving.
Q7. How to choose the right Centrifuge Tube?
- Volume – Select based on sample size (micro vs. large volume).
- Cap Type – Screw cap for secure storage, snap cap for routine use.
- Sterility – Sterile tubes for cell culture & microbiology.
- Speed Rating – Match the tube to centrifuge speed (RPM or RCF).
