MEDILAB Centrifuge Tubes with Round Bottom are high-clarity laboratory tubes designed to withstand high-speed centrifugation and rigorous daily use. These tubes provide dependable performance for sample separation, pelleting, storage, and analytical workflows. Engineered for precision and durability, they ensure consistent and contamination-free results in research, diagnostics, and quality-controlled environments.

 Key Features

  • High transparency for easy sample visualisation
  • Strong construction suitable for speeds up to 50,000 × g
  • Autoclavable (as applicable); ideal for sterile workflows
  • Leak-proof sealing with compatible caps
  • Chemically resistant to most laboratory reagents
  • The round-bottom design ensures uniform sedimentation in centrifugation
  • Smooth internal surface minimises sample retention
  • Lightweight, shatter-resistant, and safe for routine handling
  • Manufactured under strict quality controls to ensure batch consistency

Material Specifications

  • Material: Polypropylene (PP) / Polycarbonate (PC) high-grade laboratory plastic
  • Thermal Resistance: Suitable for autoclaving at 121°C (PP); PC tubes withstand autoclaving, but repeated cycles may reduce mechanical strength
  • Chemical Resistance: Excellent resistance to most acids, alcohols, and organic solvents
  • Mechanical Properties: High impact strength, superior clarity, and rigidity
  • Compliance: Manufactured as per international laboratory plasticware standards (ISO / ASTM guidelines applicable to plastic centrifuge tubes)

Technical Specifications

  • Available Capacities: As per the standard size table
  • Design: Round-bottom profile for balanced centrifugation
  • Dimensions: Standardised dimensions to fit universal centrifuge rotors
  • Tolerance: Precision-moulded for consistent wall thickness and optimal performance
  • Sterilisation: Available in sterile or non-sterile formats depending on customer requirements
  • Accessories Included: Snap or screw caps, depending on model; optional plug-style caps available

 Handling & Precautions

  • Do not use the above-recommended centrifuge speed (50,000 × g)
  • Avoid repeated autoclaving of PC tubes, as it may reduce their strength
  • Ensure proper rotor compatibility before centrifugation
  • Clean with mild laboratory detergents; avoid abrasive scrubbing
  • Store away from direct sunlight and extreme temperatures
  • Do not use with highly reactive or aggressive chemicals beyond material tolerance
  • Inspect tubes before use to ensure no cracks or deformation

Applications

  • Suitable for research laboratories, pharmaceutical companies, biotech units, chemical industries, food & beverage QC labs, environmental testing labs, universities, and clinical diagnostics
  • Used for centrifugation, sample preparation, sedimentation, phase separation, and pellet collection
  • Ideal for microbiology, molecular biology, haematology, cell culture, and routine analytical workflows
  • Supports reliable sample handling during storage, transport, and processing
