Corning Cellstack ultra-Low Attachment 1 Ch St, 8 Items CORN3303

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 strengthTC 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 A variety of optional filling caps are available to allow direct aseptic transfer of media and cells via pumping or gravity feed. Several coupling devices are available on these filling caps with or without integrally sealed USP Class VI certified C-Flex® tubing. Optional filling caps with attached filters with hydrophobic membranes provide for gas exchange and faster aseptic venting during liquid transfers. Extra sterile vented or unvented 33 mm replacement caps are also available. Reusable stacking devices fit between CellSTACK® chambers to keep them level and optimise incubator space while providing clearance for gas exchange. All caps are 33 mm threaded caps.
