The platform functions as a base for the chamber and provides clamping to make a seal between the chamber and coverslip. They are machined from aluminum and finished with a black anodize. With the exception of the model P-2 and PH-2 platforms, Series 20 platforms feature sliding hold down clamps which permit rapid replacement of the chamber. The model P-2 and PH-2 platforms use a one piece clamp as shown above. Sliding clamps used on most models permit easy removal of the chamber to change the coverslip. Model P-2, see to left, uses a one piece clamp secured with 4 screws. Heater platforms are powered from a single channel of a Warner heater controller, see page M126. Connection to the controller is made with the CC-28 cable assembly.

The CC-28 cable assembly is used to connect any Warner heater platform to a TC-324B or TC-344B heater controller. The cable has two thermistors at the platform end; the control thermistor which attaches to the platform and a bead thermistor for monitoring the bath temperature. The CC-28 is provided with a 9 pin din connector to plug into the heater controller. An alternative cable, the CC-15, is available with no inboard connector for users who choose to use another power source.

Non-heater platforms can be converted to heater platforms with an upgrade kit consisting of a pair of resistive heaters, heat transfer pads and mounting screws. Tapped holes for the heaters are included in all plain platforms. The only tool required for installation is a small Philips screwdriver. The kit is ordered with either the CC-28 or CC-15 cable assembly.
