PS, sterile. The Corning® CellSTACK® culture chambers are available in five sizes and with three different surface treatments.

• Two 26 mm diameter filling ports allow direct access to chamber bottom providing greater flexibility for sterile filling and emptying by pouring, pipetting or via tubing in a fully closed system
• Standard 33 mm threaded caps have 0,2 μm pore non-wettable membranes sealed directly to the caps to allow gas exchange while minimising the risk of contamination
• Optional 33 mm threaded caps are available with integrally sealed USP Class VI certified C-Flex® tubing to allow direct sterile transfer of media and cells via pumping or gravity feed
• Polystyrene construction provides excellent optical clarity and mechanical strength

TC treated surface: Uncharged polystyrene has an uncharged, hydrophobic surface to which cell attachment proteins bind poorly. This results in poor and uneven cell attachment and growth. Tissue culture (TC) treated polystyrene has a negatively charged, hydrophilic surface to which cell attachment proteins bind evenly. This provides a good surface for cell attachment and growth.

Corning® CellBIND® surface: The Corning® CellBIND® surface enhances cell attachment under difficult conditions, such as reduced-serum or serum-free medium, resulting in higher cell yields.
More consistent cell attachment resulting in increased cell growth
Adapts cells more quickly to reduced-serum or serum-free conditions
Reduces premature cell detachment from confluent cultures
May eliminate the need for tedious, time-consuming, low stability biological coatings
Requires no refrigeration or special handling and is stable at room temperature

Ultra-Low Attachment surface: The Ultra-Low Attachment surface is a covalently bonded hydrogel surface that is hydrophilic and neutrally charged. It minimises cell attachment, protein absorption and enzyme activation. The surface is non-cytotoxic, biologically inert and non-degradable.
Maintains cells in a suspended, unattached state
Prevents stem cells from attachment-mediated differentiation
Prevents anchorage-dependent cells from dividing
Reduces binding of attachment and serum proteins to the substrate

Chambers are sterilized by gamma radiation and certified nonpyrogenic. Manufactured under GMP conditions and 100% leak-tested prior to shipping.
