15ml Polypropylene Centrifuge Tubes, Conical Bottom, Graduated, Non-Sterile Lab Consumables (Pack of 100)

15mL Polypropylene Centrifuge Tubes — Graduated Conical Bottom

Maximize your lab budget without compromising on quality with the Apex Labs Centrifuge Tubes 15mL pack. This 100-pack of bulk-packaged, non-sterile tubes is the perfect solution for routine laboratory tasks, sample storage, and chemical processing that do not require a certified sterile environment. Crafted from high-transparency Polypropylene (PP), these tubes are engineered to endure high centrifugal forces up to 12,000 × g and offer excellent chemical resistance against aggressive reagents. Each tube features a precision conical bottom for superior sample pelleting, paired with an airtight, leak-proof flat-top screw cap to prevent spills and sample evaporation.
