Featuring a 32 cm overall handle length, this scraper is structurally optimized for reach and dexterity within high-capacity culture vessels such as 150 cm² to 225 cm² (T-150\/T-225) flasks and large roller bottles. The device utilizes an ergonomic, co-molded **pivoting thermoplastic elastomer (TPE) blade** that adjusts its pitch relative to the plastic surface, ensuring a smooth, low-shear scrape. Supplied as a commercial facility case of 250 individually wrapped scrapers, this single-use consumable guarantees clean, high-yield cell recovery while safeguarding the structural integrity of sensitive surface proteins and membranes.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance \u0026amp; Architecture\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePivoting Thermoplastic Elastomer Blade: Outfitted with a flexible, ultra-smooth TPE blade that effortlessly pivots around the handle axis. This dynamic movement allows the blade to remain flush against the contoured curves, corners, and flat floors of culture flasks, ensuring complete coverage without requiring harsh hand twisting.\u003c\/li\u003e\n\u003cli\u003eLow-Shear Mechanical Harvesting: Specially engineered to minimize physical cell lysis (cell bursting) during scraping. The blade edge cleanly lifts tenacious cell sheets (such as macrophages or tightly adherent cell lines) while preserving high cell viability and protecting delicate surface receptors from enzymatic degradation caused by trypsinization.\u003c\/li\u003e\n\u003cli\u003eExtended 32 cm Reach: The elongated, rigid polystyrene handle provides excellent leverage and extends deep into large-volume cell expansion vessels. This minimizes the risk of the operator's gloved hand contacting the flask neck, reducing external touch-contamination entry vectors.\u003c\/li\u003e\n\u003cli\u003eIndividually Sealed Aseptic Security: Every cell scraper is packed inside its own sterile, peel-apart paper\/plastic blister pouch. This configuration maintains a true aseptic boundary right up to the moment of use under the biosafety cabinet, supporting strict cGMP compliance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eModel Number \/ Catalog No: 179707\u003c\/li\u003e\n\u003cli\u003ePrimary Manufacturer: Thermo Scientific™ (Nunc™ Product Portfolio)\u003c\/li\u003e\n\u003cli\u003eOverall Handle Length: 32 cm (~12.6 inches | Optimized for T-150, T-225, and Roller Bottles)\u003c\/li\u003e\n\u003cli\u003eBlade Width Dimensions: 1.8 cm (~0.7 inches)\u003c\/li\u003e\n\u003cli\u003eMaterial Chemistry: Rigid Polystyrene (Handle) \/ Flexible Thermoplastic Elastomer (Blade)\u003c\/li\u003e\n\u003cli\u003eColor Morphology: Clinical White Handle with a Teal\/Blue Blade Profile\u003c\/li\u003e\n\u003cli\u003eSterility Status: Certified Sterile via Gamma Irradiation (Individually pouched)\u003c\/li\u003e\n\u003cli\u003ePurity Baseline: Certified Non-Pyrogenic and Non-Cytotoxic to support delicate primary and stem cell lines\u003c\/li\u003e\n\u003cli\u003ePackaging Configuration: Case of 250 Scrapers (Individually wrapped units organized neatly within a tracking-coded master carton)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Benefits \u0026amp; Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEnzyme-Free Harvesting Loops: The premier choice for harvesting cells when downstream assays (such as flow cytometry, receptor binding studies, or western blotting) require completely intact membrane proteins that would otherwise be cleaved by trypsin or Accutase®.\u003c\/li\u003e\n\u003cli\u003eHigh-Yield Adherent Cell Recovery: Maximizes total cell pellet retrieval from the interior walls of large-scale production vessels, leaving zero patches of unharvested biomaterial in tight corners.\u003c\/li\u003e\n\u003cli\u003eDownstream Functional Assays: Preserves high viability in sensitive primary cultures, microglial loops, and stem-cell-derived lines, ensuring accurate metabolic readouts in kinetic screening setups.\u003c\/li\u003e\n\u003cli\u003e**Multi-Vessel Standardization:** Provides procurement managers with a uniform, multi-vessel compatible harvesting tool that can be universally deployed across diverse cell line scaling teams.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cp\u003e\u003csmall\u003eThermo Scientific™ and Nunc™ are registered commercial trademarks of Thermo Fisher Scientific Inc.
