Cushions with Extractor (for 175mL and 225mL Conical Centrif

Meet bioanalytical-grade requirements and provide unsurpassed performance in critical research applications Exceptionally strong—Industry leading centrifugation rating of 16,000 RCF (50 mL polypropylene) Unique double threaded cap design reducing cross threading and leakage Easy-to-read graduations Consistent biological and physical propertiesIdeal for long-term cryogenic storage of specimens at -80°C (15 to 225 mL polypropylene tubes) The most dependable tube in the lab, Falcon conical tubes are easy-to-use, high quality tools to protect your precious samples. State-of-the-art design and manufacturing create tubes engineered to provide high strength, wide temperature stability, and to perform in your critical applications. They will protect your valuable samples during centrifugation, vortexing, and long term storage in the freezer. To meet this intense challenge, Falcon tubes are designed for: High strength: State-of-the-art mold design, coupled with advanced resin selection, create tube walls that are engineered to perform under high-stress situations. Nonpyrogenicity: Tested to less than 0.1 EU/mL. Nontoxicity: Resins are selected via an intense array of U.S. Pharmacopoeia (USP) toxicity tests. Low protein binding: Corning engineers and scientists are continually searching for materials and processes that minimize labware-induced interference, such as protein binding. Quality packaging: Falcon tubes, in addition to offering bioanalytical-grade performance, use medical-style packaging to better assure sterile presentation. The conical tubes are packaged in convenient reusable racks or compact environmentally-friendly bulk packs. Support cushions (Catalog No. 352090 for both 175mL and 225mL) must be used with this product unless the centrifuge rotor already has appropriate V-bottom cushions.
