Centrifuge Tube Round Bottom

GISCOM 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
