Diamond Midi 5 mL Centrifuge Tubes, PP, Red Screw Cap, Graduated, Sterile — 500/Case
The Globe Scientific Diamond Midi Centrifuge Tube is a 5 mL polypropylene tube with an assembled red screw cap, engineered for sample collection, supernatant recovery, and intermediate-volume centrifugation that falls between standard microtubes and 15 mL conicals. Printed graduations support quick volume estimation at the bench, while the leak-resistant screw closure secures samples during spins and transport.
