14. ICH compliant illumination according to CPMP/ICH/279/95 (Q1B)
14.1 BINDER ICH light
Pure cool white fluorescent tubes (light color 640 or 840) are used together with the special fluorescent
tubes “BINDER Q1B Synergy Light” available only at BINDER, which combine emission of both radiations
UVA and cool white. Combination of these tubes leads to a spectral distribution according to option 2 of
guidelineCPMP/ICH/279/95 (Q1B).
Advantages of the BINDER light system:
•
Reaching the radiation doses of UVA and LUX requested by Q1B almost simultaneously.
• After having reached the target intensity of guideline CPMP/ICH/279/95 (Q1B), you can turn off the
“BINDER Q1B Synergy Light” fluorescent tubes, which contain a UVA portion, independently from the
“cool white” fluorescent tubes emitting in the visible spectral range.
• Optimum homogeneity of the spectral distribution and the intensities in LUX and UVA on the shelf
surface, even with high intensity values, obtained by the BINDER ICH light and the special lens of the
headlight. This guarantees that all samples receive the same radiation doses, thus permitting very
precise test conditions for photo stability tests.
Fluorescent tube cool white: T8 fluorescent tube in form of a rod with a tube diameter of 26mm. Length
according to chamber size 600 mm / 23.6 in or 900 mm / 35.4 in. Emissive range in the visible spectral
range 400 to 800 nm. The relative spectral distribution meets the F6 standard (cool white) acc. to ISO
10977.
Fluorescent tube “BINDER Q1B Synergy Light”: T8 fluorescent tube in the form of a rod with a tube
diameter of 26 mm /1.02 in. Length according to chamber size 600 mm / 23.6 in or 900 mm / 35.4 in.
Emissive range in the visible spectral range 400 to 800 nm. Emissive range in the UVA range 320 to 400
nm.
WARNING
UV light hazard.
Eye and skin injury.
∅
Do NOT look directly into the light.
 Minimize skin exposure.
The maximum allowed ultraviolet exposure emitted by this unit on unprotected skin or eye shall not ex-
ceed 7.7 hours per day.
The waste heat of the fluorescent tubes leads to a modification of the temperature - humidity diagram:
When operating the chamber with illumination: Restricted temperature and humidity range 20
°C / 68 °F to 60 °C / 140 °F , at 20 °C not below 30 % r.H.
14.2 Adjustable light cassettes
The KBF P is equipped with fluorescent tubes for UVA and the visible spectral range. Special reflector
material in the cassettes ensures optimum light diffusion and efficient utilization of the high light intensity.
The lens of the headlight leads to a homogeneous intensity distribution even with a short distance to the
shelf. The fluorescent tubes are built in light cassettes that can be freely positioned within wide areas.
They homogeneously illuminate the racks below them.
