Open Diamond Bath Imaging Chambers (RC-22, RC-22C)

Open Diamond Bath Imaging Chambers (RC-22, RC-22C)

The RC-22 and RC-22C are small volume, open bath recording chambers designed for tissue and brain slice studies.

  • Designed for tissue slice samples or cell cultured coverslips
  • Applications include patch clamp, intracellular / extracellular recordings, and imaging
  • Diamond shaped bath provides laminar solution flow
  • Small bath volume facilitates rapid solution exchange
  • Tissue slice anchor included

The RC-22 and RC-22C feature an open bath and include a slice anchor. The diamond shape geometry of these chamber baths facilitate laminar solution flow which can provide minimal distortion of the sample during perfusion.

Slices are secured via a supplied stainless steel anchor (or harp). Threads are made of Lycra© and have a spacing of 1.5 mm. The RC-22 is supplied with an SHD-22L/15 anchor, and the RC-22C is supplied with an SHD-22CL/15 anchor. While anchor mass (typically 300 milligrams) may be sufficient to hold a slice in place, Warner anchors rely on a close fit between the anchor body and the chamber sidewall. This feature can reduce stress on the anchored slice.

Solution aspiration is via a stainless steel suction tube which is secured by a clamp. This insures that the adjustable-height suction tube will not move once set by the user. Each chamber has an agar bridge well for reference electrodes. The working volume of the RC-22 and RC-22C is 115 µl and 138 µl, respectively. Chamber sidewalls have a height of 1.2 mm to facilitate electrode access and placement.

The RC-22 and RC-22C chambers require a platform (P-1, PH-1, or PM-1) and stage adapter to complete the assembly for mounting onto a microscope. The bottom-forming coverslip is 22 x 40 mm.


Each chamber is supplied with a slice anchor, a swatch of nylon mesh, a pack of #1 thickness glass coverslips (CS-22/40, 22 x 40 mm, 50/pkg) and 10 ft of PE-160 tubing.
