GENESYS 30 Spectrophotometer 

 

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.
