OpenTop Lid for Alkaline Resistant RDE/RRDE Cell

This lid was designed for strong alkaline work, where base concentrations > 0.5 M and traditional borosilicate cells will be attacked by base. The lid is machined from solid PTFE, and features a central 24/25 port for the RDE/RRDE shaft and four radially positioned 14/20 ports, machined directly into the lid. The OpenTop lid fits against the alkaline resistant cell (sold separately) flange, against a fluoroelastomer gasket for sealing. It is sold as part of a Rotating Disk/Ring-Disk Alkaline Resistant Cell Kit (including cell and clamps). This product is only the lid, as a replacement or additional lid if you already own the alkaline resistant cell kit.
