Centrifuge Tubes are specialized disposable containers (polypropylene) designed to withstand high centrifugal forces (up to 30,000 x g) for separating biological fluids based on density. Available in microcentrifuge sizes (0.2-2.0 mL), conical tubes (15 mL, 50 mL), and larger volumes (100-500 mL). Features include leak-proof screw caps with O-rings (conical tubes), snap caps (microcentrifuge tubes), graduated volume markings, writing areas, and sterile/non-sterile options. Certified RNase/DNase-free, pyrogen-free, and autoclavable. Primary clinical applications include blood component separation (serum/plasma), urine sediment preparation, microbiology sample concentration, molecular biology (DNA/RNA extraction), cell culture processing, protein/enzyme analysis, and viral load testing. Critical safety precautions include never exceeding maximum RCF rating, proper balancing by weight, secure cap tightening, inspection for cracks, and disposal as biohazardous waste. Essential consumable in every clinical, research, and industrial laboratory.
