Bipolar/Monopolar Temperature Controller Model TC-202A User’s Manual
The Bipolar/Monopolar Temperature Controller (Model TC-202A) is designed to be used with several micro-incubators supplied by Harvard Apparatus Inc.These models include the Open Perfusion Micro-Incubator (Model PDMI-2), Patch Slice Micro-Incubator (Model PSMI),Leiden Static Micro-Incubator (Model LU-CB1) Leiden Closed Perfusion Micro-Incubator (Model LU-CPC-CEH) and Brain/Tissue Slice System (Model BSC-BU).
A micro-incubation system from Harvard Apparatus consists of the Temperature Controller (TC-202A),a micro-incubator (one of the above) of choice,a 35 mm plastic Petri dish or reusable cover slip dish (LU-CSD, MSC-TD or MSC-PTD) and an associated pumping system.Such a system allows complete environmental conditioning along with excellent micro-mechanical access for electrodes or micropipettes, all with optimum optical access.
A proportional temperature controller is basically a source of electric current whose magnitude is determined by comparing a desired target temperature with its current value. The TC-202A’s output is proportional to the difference in temperature between the desired and the current value. This type of system avoids the electrical noise of suddenly turning current on and off, unlike less expensive controllers. When using the TC-202A in the Biphasic mode, the current will spontaneously reverse direction when the current temperature is too high; in short,it can also cool when used with Peltier elements.(PDMI-2/PSMI)
