The TC-202A Bipolar Temperature Controller, the new and improved version of the TC-102 Monopolar Temperature Controller, operates with micro-incubators to provide both heating and cooling functions for life science research purposes.

While the unit has multiple potential uses, it has been designed as an ideal companion unit for Harvard Apparatus/Medical Systems Peltier-based micro-incubators. In its monopolar mode, however, the TC-202A efficiently controls microincubators that use resistive heaters such as the Leiden Micro-Incubator Systems and the BSC-BU Brain/Tissue Slice Chamber units.
Because the TC-202A is bipolar, it is ideally suited for use with Peltier devices such as those built into our models PDMI-2 Open Perfusion Micro-Incubator, PSMI Patch Slice Micro-Incubator and CSMI Chambered Slide Micro-Incubator.

Flexible
The TC-202A allows the researcher to control the command temperature from alternative locations. In the case of the PDMI-2, PSMI and CSMI micro-incubators, temperature is controlled either from a thermistor placed in the bath, or from a second thermistor permanently positioned on the plate containing the regulated surface of the Peltier devices.

Accurate
Accurate temperature control (±0.2°C) is achieved by sensing temperature with a miniature thermistor, digitizing the thermistor signals, and then proportionally regulating a low noise DC current output. Current output is also regulated to match the thermal time constants of small systems, such as micro-incubators, thus minimizing initial set-up overshoot and oscillations about the set point.
