30 cf Photostability Chamber

30 cu. ft. Photostability Chamber

Three-Shelf 30-Cu. Ft. Photostability Chamber

  • Air-cooled internal refrigeration system.
  • Door latch allows for a pad lock.
  • System will be capable of operating in the range defined below:
    • Minimum air temperature of 5°C (with no RH control)
    • Minimum air temperature of 15°C (with RH control)
    • Maximum air temperature of 30°C
    • Maximum dew point of 25°C
    • Minimum dew point of 8°C
  • Temperature and relative humidity tolerance will adhere to International Conference on Harmonization (ICH) Guideline for Stability Testing over the defined operating range.
    • Temperature ± 2°C
    • Relative humidity ± 5%
  • Digital high grade, thin film temperature compensated RH/temperature sensor/transmitter which allows for very convenient, low cost calibrations.
  • Safety devices including over-temperature safety switch, high and low refrigeration pressure switch and low water cutoff.
  • Three adjustable-intensity, lighted shelves
    • Any combination of shelves (visible verses UV) can be selected at the time of order.
      • The ballasts for the visible and UV lamps are interchangeable.  The lamps can be replaced to convert from one type of light source to another.   (If the automatic light control feature is purchased the light sources are not interchangeable).
    • Each shelf will adhere to photo stability requirements as defined in the International Conference on Harmonization (ICH) Guideline Q1B entitled Guidance for Industry Q1B Photo Stability Testing on New Drug Substances and Products
    • Maximum usable height from light source to process area bottom will be 14”.  This includes riser and light sensor area if so equipped.
    • Basic light source includes a manual dimmer for light intensity control. See OPTIONS for automatic light intensity control.

Fluorescent shelf

  • Light source as defined by ISO 10977
    • 16″ long, 4 pin base, compact fluorescent
    • 4000° Kelvin color/temperature
  • Light uniformity better than 10% RSD over defined, usable area of each shelf.
  • Light source will be isolated from the individual product shelf by a clear, acrylic barrier.

Ultra-violet shelf

  • Light source as defined by ISO 10977
    • 358 nanometers peak wavelength
    • 16″ long, 4 pin base, compact fluorescent
  • Light uniformity better than 10% RSD over defined, usable area of each shelf.
  • Light source will be isolated from the individual product shelf by a clear, acrylic barrier.

    • FDA 21 CFR Part 11 compliant data file
    • Paperless digital recorder
    • Data is stored on compact flash memory.  Memory can be removed for PC access or data can be transferred via serial or Ethernet connection.
    • 5 channels
    • Serial port (RS-232/RS-485 or Ethernet)
    • Capable of recording dry bulb temperature, RH and light intensity on three separate shelves.
