Fisherbrand Centrifuge Tube 1.5 ml Screw Cap with O-Ring 500 Tubes

The Fisherbrand 2681372 Centrifuge Tube is a small laboratory consumable designed for efficient and secure handling of samples. This tube has a capacity of 1.5 ml and is constructed from durable polypropylene (PP), a plastic known for its excellent chemical resistance and ability to withstand the forces of microcentrifugation.

A key feature is the screw cap with an O-ring seal. The screw cap provides a strong, mechanical closure, while the O-ring enhances the seal's integrity, making the tube highly leak-proof. This superior seal is essential for preventing evaporation and is ideal for cryogenic storage (e.g., in ultra-low freezers). Furthermore, the tube has a free-standing (skirted) base, allowing it to stand upright on a workbench without requiring a separate rack, which simplifies handling and transfer steps.

This Fisherbrand centrifuge tube is a reliable and essential tool for various molecular biology and research applications.
