Fisherbrand Centrifuge Tube 1.5 ml Locking Snap Cap PP 2000 Tubes

The Fisherbrand 14-666-319 Centrifuge Tube is a premium 1.5 mL microcentrifuge tube engineered for applications requiring extra sample security. Constructed from clear polypropylene (PP), it is designed to withstand high centrifugal forces and extreme temperature changes.

The standout feature of this specific tube is its Locking Snap Cap. Unlike standard snap caps that rely solely on friction, this cap features a specialized locking mechanism (often a clip or extended lip) that "clicks" securely into place.

Boiling/Heating: The lock prevents the lid from popping open due to internal pressure buildup during boiling or incubation steps.

Sample Security: It provides an extra assurance against accidental opening during handling or storage, which is vital for radioactive or hazardous samples.

Despite the secure lock, the tube is designed to be pierceable for syringe access and is typically rated for high speeds (often up to 30,000 x g), making it suitable for pelleting nucleic acids or proteins.
