Thermo Scientific Nunc Cell Scraper 23 cm Individually Sealed Box of 50

Thermo Scientific 179693 Nunc Sterile Cell Scraper (23 cm Total Length, Individually Sealed). A single-use, ergonomic sterile cell culture harvesting tool featuring a flexible, pivoting thermoplastic elastomer blade engineered for gentle, mechanical detachment of adherent cells from culture flasks, dishes, and bottles without enzymatic trypsinization or membrane damage.

• MPN / Catalog Model: 179693 (Nunc Cell Scraper Series)
• Manufacturer & Line: Thermo Fisher Scientific / Thermo Scientific Nunc Cell Culture Consumables
• Dimensions & Sizing: 23 cm (approx. 9.0 inches) overall handle length with a 1.3 cm (13 mm) blade width; specifically proportioned for standard small-to-medium culture vessels (such as T-25, T-75 flasks, and 35 mm to 100 mm petri dishes)
• Material Construction & Blade Flexibility: Rigid, lightweight polystyrene (PS) handle paired with a soft, pliable thermoplastic elastomer (TPE) / polyethylene blade; prevents scratching of tissue-culture-treated (TC) vessel surfaces while maximizing cell viability
• Blade Geometry & Pivoting Action: Pivoting, flexible blade head automatically conforms to curved flask shoulders, corners, and flat culture surfaces under light downward pressure, ensuring uniform harvesting efficiency across hard-to-reach regions
• Handle Ergonomics: Ribbed, non-slip cylindrical shaft engineered for precise fingertip control and comfortable rotation inside biosafety cabinets while wearing double nitrile or latex gloves
• Sterility & Purity Certification: Sterilized via gamma irradiation (SAL 10^-6); certified non-pyrogenic, DNase-free, RNase-free, and human DNA-free to safeguard sensitive downstream molecular and cellular assays
• Packaging & Format: Individually sealed in peel-open sterile plastic/paper blister pouches to maintain sterility per unit and prevent cross-contamination during aseptic single-use workflows
• Primary Application: Mechanical harvesting of adherent mammalian cell lines (e.g., HEK293, HeLa, CHO, fibroblasts, primary cells), harvesting cells sensitive to proteolytic enzymes (trypsin/Accutase) where preservation of intact cell-surface receptors/antigens is required for flow cytometry, Western blotting, or membrane protein isolation
