Description of Membrane H-Cell Kit

The kit includes two each of the following: glass half-cell, PEEK cap, Luggin tube with Teflon mount, inlet with frit and outlet tube. In addition, the kit has one large pinch clamp (#34) to hold the two halves together, and #-123 Viton o-rings (standard circular cross-section and X-shaped cross-section). Only two o-rings needed to assemble the cell; extras are included.

The Standard H-Cell Kit includes:

  • Two (2) Pseudo-disposable Ag/AgCl gel RE: Low Profile Silver/Silver Chloride Gel (p/n RRPEAGCL).
  • Two (2) Pt wire coil CE/WE/Drive Electrodes (p/n RRPG257PT).
  • Other RE and Drive Electrode types subject to availability.
