Specific Purpose Chambers (TH-ICH) from The Cleanroom Market

Specific Purpose Chambers (TH-ICH)

Manufactured in accordance with ICH Guidelines Q1A-Stability test (R2), Q1B-Photostability test (Option 2).


Different specifications and extras available. 

Control range

  • Temperature range from 0 to 120°C Humidity range from 30 to 95% RH



  • Microprocessor PID control / Temperature calibration / Automatic tuning.
  • Rapid humidity control is achieved by adapting the humidification tank interior to the chamber.
  • Air-tight door closure with perfect sealed packing.
    – Heat-resistant silicone packing completely blocks high heat leakage from the inner chamber.


  • Two different sized models available to suit any users’ needs.
  • Corrosion resistant stainless steel chamber.
  • Cable port for introduction of external probes or wires.
    – 50mm diameter cable port comes standard on the left side of the unit.
    – Additional 50mm or 80mm diameter cable ports, custom ordered. (optional)
  • Inner glass door with entry ports for handling samples without affecting inner chamber temperature and humidity. (optional)
  • Casters for easy mobility during installation or relocation.
  • User friendly LCD controller.
    – Set value and present value are clearly visible together on display.
    – Operating progress visible in graph mode allow for direct data interpretation.
    – Temperature and other operating parameters recorded with use of selectable recorder. (optional)
  • Sufficient programmable control support.
    Description TH-ICH
    Programmable pattern capacity 10
    pattern repeat time 999
    Max. Segments per a pattern 100
    Available max. segments* 100
    Programmable process time per a segment 0 to 99 hr. 59 min.

    * Even though the max. segments per a pattern are 100, available total segments are up to 100 not 1000, so you need to arrange the number of segment and patterns properly.


Computer interface.
– RS-485 communication port enables connection of up to maximum 9 units. Simultaneous monitoring and operating of multiple units is an available feature. (optional)
– Program patterns are simple to set with the use of our software.
– Storage of program information, backup of value settings, recovery, temperature, humidity values.
– RS-232 communication port comes standard.


Stability test ICH guideline Q1A (R2)

  • Operating progress visible through graph mode for better data analyzation.
