Five-O™ 5 mL Screw Cap MacroTubes®

Five-O™ 5 mL Screw-Cap MacroTubes® combine the durability and convenience of traditional 15 mL conical tubes with a compact, resource-efficient 5 mL format. Designed for enhanced space savings and reduced plastic consumption, these versatile polypropylene tubes support a wide range of laboratory workflows, from boiling applications to long-term sample preservation at –86°C to +121°C.

Choose between sterile racked packaging with attached screw caps or non-sterile bulk packaging with separate caps. The racked format features foam racks similar to those used for 15 mL tubes but requires approximately 60% less storage space. These tubes are fully compatible with standard laboratory equipment, making it easy to integrate them into existing centrifugation, storage, and processing protocols.

Five-O™ MacroTubes® deliver exceptional clarity, dual graduations at 0.2 mL and 0.5 mL, and are certified RNase-, DNase-, and pyrogen-free, ensuring clean and reliable performance in molecular biology and general lab applications. With a maximum centrifugal force rating of 25,000 x g, they meet the demands of high-speed centrifugation.

Main Attributes

• Compatible with standard equipment and rotors
• Screw-cap design for secure, leak-resistant sealing
• Centrifugation rated up to 25,000 x g
• Dual graduations at every 0.2 mL and 0.5 mL
