Product Description
LIGHT LABS is proud to offer the CELLTREAT 2.0 mL Micro Centrifuge Tube (Cat # 229446) — a premium, sterile, general-purpose 2.0 mL microcentrifuge tube engineered for the widest possible range of routine laboratory applications, from standard sample preparation and storage to high-speed centrifugation at up to 25,000 x g. The 229446 is the go-to 2.0 mL microcentrifuge tube for researchers who demand reliable performance, consistent quality, and excellent value in a sterile format.
Each tube features a frosted marking spot for clear, smudge-resistant pencil or marker labeling — a practical advantage vs. smooth-walled tubes where ink labels can smear or peel — along with engraved graduations molded directly into the tube wall for permanent, accurate volume reference that will not fade or rub off with repeated handling, freeze-thaw cycling, or solvent exposure. The attached flat top snap cap is designed for easy one-hand opening and closing — a critical convenience feature during rapid, high-throughput sample processing workflows where both hands are frequently occupied. The snap cap forms a secure, leak-resistant closure that maintains sample integrity during centrifugation, vortexing, storage, and transport. Manufactured from medical-grade polypropylene certified RNase-free, DNase-free, and nonpyrogenic, and sterilized by gamma irradiation. Packaged 1,000 tubes per resealable bag, 5 bags per case (5,000 tubes total). LIGHT LABS is your trusted source for CELLTREAT laboratory plasticware.
