50 mL Sterile Polypropylene Self-Standing Centrifuge Tubes
Manufacturer: United Scientific
The 50 mL Sterile Polypropylene Centrifuge Tubes from United Scientific are designed for maximum efficiency in the laboratory. Featuring a skirted flat bottom, these tubes stand upright on any flat surface, eliminating the need for a tube rack during sample preparation, pipetting, or temporary storage. Manufactured from high-clarity polypropylene (PP), these tubes allow for easy visual inspection of samples. They are steam sterilized, making them ready for immediate use in microbiology, cell culture, and general research. With a maximum RCF of 9,000 x g, they provide the structural integrity required for standard tabletop centrifugation.
Description
Features:
- Self-Standing Design: The flat base allows the tube to stand upright on any flat surface, maximizing efficiency in sterile hoods and busy benches
- High-Contrast Markings: Silk-screened black graduations provide superior visibility against clear liquids, complemented by a large white marking spot for easy sample identification
- Thermal Versatility: Validated for extreme environments, these tubes are freezable to -45°C for long-term storage and autoclavable at 121°C for reuse or decontamination
- Leak-Proof Seal: The blue HDPE screw caps are precision-threaded to prevent evaporation and leaks, even during high-speed centrifugation up to 9,000 RCF
Usage & Safety Tips:
Centrifugation Safety: When centrifuging skirted (self-standing) tubes, ensure your centrifuge rotor is specifically designed to support the flat-bottom geometry. Using skirted tubes in standard conical-only buckets at high speeds may cause the skirt to crack.
- Autoclaving: Always loosen the screw caps before autoclaving to allow for pressure equalization and prevent tube deformation.
- Chemical Resistance: Polypropylene offers excellent resistance to most common laboratory acids, bases, and solvents at room temperature.
