The TC-202A Bipolar Temperature Controller, the new and improved version of Medical Systems' TC-102 , operates with Harvard micro-incubators to provide temperature control functions for life science research purposes.

While the unit has many potential uses, it has been designed as an ideal companion unit for the Harvard Apparatus/Medical Systems Peltier-based micro-incubators. Because the TC-202A is bipolar, it is ideally suited for use with Peltier devices such as the models PDMI-2 Open Perfusion Micro-Incubator, PSMI Patch Slice Micro-Incubator and CSMI Chambered Slide Micro-Incubator.

In its monopolar mode, the TC-202A efficiently controls microincubators that use resistive heaters such as the LU-CB1 Leiden open bath micro-incubator, LU-CPC-CEH Leiden closed bath system, and the BSC-BU Brain/Tissue Slice Chambers with either the Zbicz or Haas tops.


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 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.
