Frequently Asked Questions
What are centrifuge tubes used for in laboratory workflows?
In routine lab work, centrifuge tubes hold samples that need separation by speed. They allow you to collect pellets, clear supernatants, or isolate phases without disturbing the sample during handling. Pair with compatible centrifuges for optimal separation results.
What sizes and formats do centrifuge tubes come in?
Most labs use microtubes for small volumes and 15 mL or 50 mL conical tubes for general processing. Larger formats also exist for high-volume runs or specific rotors used in production or QC labs.
How do I choose the right material and specification for centrifuge tubes?
Selection is based on speed rating, sample type, and temperature range. Polypropylene works for most daily tasks; higher-speed or cold-room work may require tubes with verified g-force and chemical resistance ratings.
