Centrifuge Tube with Blue Screw Cap, Free Standing, Bulk Bag Sterile

Maximize efficiency and benchtop convenience with our 15mL and 50mL Free-Standing Sterile Centrifuge Tubes with Blue Screw Caps. Unlike standard conical tubes, these tubes feature a specialized skirted base that allows them to stand completely upright on your lab bench or biosafety cabinet without the need for a rack. Manufactured from ultra-clear, premium polypropylene, they are packed in cost-effective bulk bags to suit high-volume workflows. Each tube comes sterilized and features a flat, leak-proof blue screw cap optimized for single-handed operation, secure sealing, and easy labeling, making them the perfect choice for routine sample preparation, storage, and transport.

Common Laboratory and Research Uses 

• Benchtop Reagent Dispensing: Stands independently on any flat surface, allowing for quick, single-handed pipetting of buffers, stock solutions, dyes, and growth media.
• Sample Pooling & Storage: Ideal for collecting, isolating, and storing specific volumes of cell culture supernatants, chemicals, or clinical specimens.
• Low-Speed Separation: Frequently used for gravity settling or low-speed centrifugation workflows where a skirted base is preferred.
• Field Sample Collection: Excellent for environmental water testing, soil sampling, or field collections where laboratory tube racks are unavailable.
• Fraction & Waste Collection: Serves as a convenient containment vessel for liquid chromatography fractions or running hazardous waste streams.
