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

These 50ml free-standing centrifuge tubes have blue screw caps, come sterile in a bulk bag of 50, and make bench work quicker and easier. Unlike standard conical tubes, they have a skirted base that lets them stand upright on your bench or in a biosafety cabinet without a rack. They're made from clear polypropylene and packed in cost-effective bulk bags for high-volume work. Each sterile tube has a flat, leak-proof blue screw cap that's easy to open one-handed, seals securely and is easy to label, which makes them a good choice for routine sample preparation, storage and transport.

Common Laboratory and Research Uses

• Dispensing reagents on the bench: The tubes stand on any flat surface, so you can pipette buffers, stock solutions, dyes and growth media one-handed.
• Pooling and storing samples: Collecting, separating and storing set volumes of cell culture supernatant, chemicals or clinical specimens.
• Low-speed separation: Often used for gravity settling or low-speed centrifuging where a skirted base is preferred.
• Field sampling: Good for environmental water testing, soil sampling or field collection where there are no tube racks.
• Fraction and waste collection: A convenient container for liquid chromatography fractions or hazardous liquid waste.
