DESCRIPTION
The P4400 Thermo Scientific GENESYS 30 Spectrophotometer (G30) is a device used to measure the optical absorbance of
transparent samples in the spectrum of visible light. It is designed to be simple and fast with the highest performance and
quality.
The spectrophotometer is built for the fast-paced, high-volume processing environment, and can withstand the rigors of daily
usage for many years.
APPLICATION
The G30 is used for the measurement of optical absorbance of dosimeters using a select wavelength in the visible spectrum,
such as GEX B3 radiochromic film dosimeters, and FWT-60 radiochromic film dosimeters. The instrument is combined with
specially designed dosimeter holders which position the dosimeters appropriately to obtain accurate and repeatable
measurements.

Store the instrument in a cool and dry location. INSTALLATION Please refer to the Thermo Scientific GENESYS 30 Spectrophotometer User Guide for explicit detail. Information supplied herein should be considered supplemental or redundant and is specific to usage for dosimetry in radiation processing applications. - Page 3 Product Specifications and Usage Information P4400 GENESYS 30 Spectrophotometer Instrument performance should be verified when operating outside of these ranges. GEX has verified instrument performance at an altitude of approximately 1610m. The instrument should be positioned on a surface that is level and free of vibration. Consider all GLP’s (Good Laboratory Practices) concerning cleanliness of the area.
- Page 4 The instrument can be used when disconnected from a PC to make measurements. For most users, this will never be a necessity, but some users may find it useful despite the limitations from using the instrument in this manner. For more information on making fixed or scanning measurements, see the Thermo Scientific GENESYS 30 User Guide. Fixed Wavelength Measurements:...
