The 7800 Visual Patching and Imaging Chamber consists of an aluminium heat exchanger plate heated by a thin heating element. The heat exchanger supplies concentric heat to the chamber itself and in-line heat to the incoming perfusate ensuring both are heated uniformly.
A thermistor embedded in the plate gives temperature feedback to the control system. In its upper surface the plate has a series of annular grooves to carry up to four perfusate tubes. The perfusate tubes carry perfusate to the central chamber at very low level encouraging laminar flow across the chamber.
