Ventacon can supply a light trap to fit permanently into this aperture allowing cables and tubes to exit the sample chamber in complete safety. Further information on cabling can be found on the Safe Operations page.

All Nicolet accessory users planning to purchase Ventacon products (except those buying the Model SR-1 Sample Rotator and battery pack Model D-4) must purchase and fit safely the Ventacon Model A-22 Light Trap into this aperture before attempting to use the company’s products.

Note : Operation of the Raman system with the metal sample aperture removed and left open , or with the lid open and the instrument manufacturer’s interlocks over-ridden is EXTREMELY HAZARDOUS.
