(PHC Series) Heater/Cooler Jackets

Product Summary

Designed to bring heating and cooling to Warner's classic Series 20 recording and imaging chambers.

  • Optimized for the SC-20 Dual In-line Solution Heater/Cooler
  • Jackets are available for both upright and inverted microscopes
  • Maintains temperature for both perfused and static bath configurations
  • Heats or cools both base platform and perfusate solution to the same temperature

The PHC Series Heater/Cooler Jackets are designed to bring heating and cooling to our classic Series 20 Imaging and Recording Chambers. Accurate temperature control from 5° to 50°C can be achieved using the PHC Series jackets in concert with the SC-20 Dual In-line Solution Heater/Cooler and CL-200A or CL-100 Bipolar Temperature Controller. (An LCS-1 is also needed for the SC-20 water jacket.)

Heated or chilled water flows from one of the SC-20 flow lines into the PHC Series Jacket(which is in direct thermal contact with the Series 20 Chamber bottom coverslip). Perfusate is heated or cooled to the same temperature as the chamber by use of the second SC-20 flow line which is fed into the bath of the Series 20 chamber.


The PHC-1 is used for upright microscopes and provides a complete thermal barrier between the chamber-forming coverslip and the local environment. The PHC-2 is designed for inverted microscopes and provide for either rectangular or round openings. (See specifications for chamber jacket compatibility with specific chambers.)


PHC Series Heater/Cooler Jackets are provided with a mounting platform, which replaces the standard platforms used with Series 20 chambers. The platform functions as a base for the jacket/chamber sandwich and provides the clamping pressure to make a tight seal. Mounting platforms are machined from black Delrin and are compatible with all  Series 20 stage adapters.

All PHC Heater/Cooler Jackets are 0.04" (1 mm) thick.
