Centrifuge Tubes 50ml Conical Sterile 50/bag

Conical centrifuge tubes are lab essentials designed with a tapered bottom (cone shape) to facilitate pellet formation during centrifugation. They are widely used in sample processing, cell culture, and molecular biology.  

Key Features & Benefits  

1. Conical Bottom Design  

• Efficient pellet collection 
• Concentrates solids at the tip for easy retrieval.  
• Better phase separation – Ideal for liquid-liquid extractions (e.g., DNA/RNA isolation).  
• Leak-proof closures – Screw caps, snap caps, or O-ring seals prevent spills.  
• Sterility options – Pre-sterilized (DNase/RNase-free) for sensitive applications.  
• Graduated markings – For accurate volume measurements.  
• High-speed compatibility – Withstands centrifugal forces (e.g., 15,000+ RCF for microtubes).  

2. Material Options 

• Polypropylene (PP) – Most common; autoclavable (121°C), chemically resistant to acids, bases, and solvents.  

3. Applications  

• Cell culture: Harvesting cells/pellets.  
• Molecular biology: DNA/RNA extraction, protein purification.  
• Clinical labs: Blood/urine separation.  
• Industrial use: Bioprocessing, chemical sample prep.
