The Attofluor cell chamber is a durable and practical coverslip holder designed for viewing live cell specimens on upright or inverted microscopes. Because the chamber is constructed from surgical stainless steel and is autoclavable, cells can be grown directly on coverslips within the unit. The O-ring seal design prevents samples from being contaminated by oil or leakage of media from the coverslips. The chamber accepts 25 mm round coverslips and mounts in a standard 35 mm diameter stage holder, and the 0.5 mm base dimension allows clearance for the objective when focusing. Spare O-rings for the Attofluor cell chamber are available in sets of ten (Cat. no. O-14804).
