Precision-molded from high-purity virgin polystyrene, each dish is permanently modified with a covalently bound, hydrophilic, neutrally charged **Ultra-Low Attachment (ULA) hydrogel layer**. This layer minimizes non-specific protein binding, completely preventing anchorage-dependent cell lines from grounding, stretching, or initiating surface-driven differentiation pathways. Supplied as a targeted laboratory case of 20 individually wrapped dishes, this sterile, single-use configuration provides cleanroom aseptic security for cell biology workflows, organoid engineering, and high-purity 3D cellular modeling loops.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance \u0026amp; Surface Chemistry\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCovalently Bound Hydrogel Layer: Features a stable, ultra-thin hydrogel matrix bonded to the polystyrene substrate. This neutral barrier suppresses the adsorption of serum proteins, fibronectin, and vitronectin, neutralizing the chemical triggers that drive cell attachment.\u003c\/li\u003e\n\u003cli\u003e3D Spheroid and Cluster Optimization: By denying an anchorage plane, cells are forced into a continuous suspension state. This forces natural cell-to-cell signaling loops, promoting the self-assembly of uniform 3D multi-cellular tumor spheroids (MCTS) or embryoid bodies.\u003c\/li\u003e\n\u003cli\u003eInverted Optical Clarity Profile: Molded with an optically flat base that ensures high light transmission and low background autofluorescence. This setup allows for distortion-free phase-contrast and high-resolution inverted fluorescence microscopy tracking.\u003c\/li\u003e\n\u003cli\u003eAseptic Peel-Pack Isolation: Every dish is pre-sterilized via validated gamma-irradiation loops and individually sealed in a heavy-gauge polymer peel-pouch. This allows operators to easily transfer single units into a biosafety cabinet without compromising cleanroom barriers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCatalog Number \/ MPN: 3261\u003c\/li\u003e\n\u003cli\u003ePrimary Manufacturer: Corning Life Sciences\u003c\/li\u003e\n\u003cli\u003eDish Nominal Scale: 60 mm Nominal Diameter x 15 mm Depth\u003c\/li\u003e\n\u003cli\u003eActual Growth Surface Dimensions: $\\approx 52.1\\text{ mm}$ Actual Base Diameter x $14.2\\text{ mm}$ Internal Height\u003c\/li\u003e\n\u003cli\u003eSurface Chemistry: Ultra-Low Attachment (ULA) Hydrogel Coating (Neutrally charged, non-ionic surface profile)\u003c\/li\u003e\n\u003cli\u003eMaterial Composition: Optical-grade, USP Class VI Virgin Polystyrene (PS) | 100% Latex-Free\u003c\/li\u003e\n\u003cli\u003eDish Growth Base Area: Nominal 21.3 cm² total base surface area\u003c\/li\u003e\n\u003cli\u003eSterility \u0026amp; Purity Standards: Gamma radiation-sterilized (SAL $10^{-6}$ parameter); Certified Non-Pyrogenic and Non-Cytotoxic\u003c\/li\u003e\n\u003cli\u003ePackaging Configuration: Case of 20 Dishes (Individually bagged units nested securely inside a track-coded master shipping carton)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Benefits \u0026amp; Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTumor Biology \u0026amp; Spheroid Cultivation: Provides the benchmark environment for generating tumor spheroids from primary biopsies, enabling accurate \u003ci\u003ein vitro\u003c\/i\u003e drug toxicity panels and oncology modeling.\u003c\/li\u003e\n\u003cli\u003eStem Cell \u0026amp; Embryoid Body Staging: Prevents early, surface-mediated differentiation of pluripotent stem cells (iPSCs\/ESCs), maintaining pluripotency markers during initial multi-lineage expansion or cluster formation.\u003c\/li\u003e\n\u003cli\u003ePrimary Tissue Harvest Maintenance: Serves as an ideal, non-binding pooling basin for fragile neural cells, hepatic clusters, or pancreatic islets immediately following mechanical or enzymatic dissociation.\u003c\/li\u003e\n\u003cli\u003e**Audit-Ready Inventory Control:** Every sterile blister pouch is directly printed with the catalog number, manufacturing lot code, and expiration metric to streamline compliance tracking inside cGMP-regulated bioprocessing lines.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cp\u003e\u003csmall\u003eCorning® is a registered commercial trademark of Corning, Inc.
