    • Unique covalently bonded hydrogel surface is hydrophilic and neutrally charged
    • Surface is designed to maintain cells in a suspended, unattached state. Greatly reduces binding of attachment and serum proteins, minimizing cell attachment and spreading
    • Prevents stem cells from attachment-mediated differentiation
    • Prevents anchorage-dependent cells from dividing
    • Minimizes protein absorption, enzyme activation, and cellular activation
    • Biologically inert, noncytotoxic and nondegradable
    • Optically clear virgin polystyrene
    • Rectangular flasks have a ramp from the bottom to the canted neck for easier pouring and pipet access and have an anti-tip skirt to enhance stability
    • U-shaped flasks have rounded shoulders for an easier grip and better access when removing or tightening the cap.
    • Lot numbers for ease in traceability
    • 100% integrity tested
