Product Description

The 50ml screw cap centrifuge tubes feature a leak-proof screw tip design and conical bottom optimized for high-speed sample processing. Constructed from durable, chemical-resistant polypropylene, these screw tip centrifuge tubes 50ml accommodate a wide temperature range (-80°C to 121°C) and withstand centrifugal forces up to 25,000 × g. The conical bottom centrifuge tubes 50ml are ideal for clinical, biotech, and research applications requiring precise pellet collection. With a total capacity of 50ml, the tubes include graduation marks for volume measurement and an ergonomic screw cap for secure sealing. Their standardized dimensions (118mm height × 29mm diameter) ensure compatibility with rotors across industrial and laboratory centrifuges. Key advantages include exceptional clarity for visibility, autoclavability, and reduced risk of cross-contamination, though their rigid design limits flexible sample handling compared to microtubes.
