Spectrometers

The SPF-290S Sunscreen Protection Factor Analyzer System measures the UV-A and UV-B spectral regions (290 nm to 400 nm) of sun creams, cosmetics and fabrics to ascertain their SPF value. Used by Boots, Avon, Estee Lauder, L'Oreal, Procter & Gamble, Pfizer and many more, the SPF-290S is an alternative UV spectrometer to in-vitro testing.

Measurement of Sun Protection Factor (2009 SPF)

The SPF-290S is a recording UV spectrophotometer designed and optimised for the determination of SPF values.

UV Spectrophotometer

Description

The SPF-290S is a recording UV spectrophotometer designed and optimised for the determination of SPF values on a variety of sunscreen and cosmetic products reducing the need (and cost!) for in vivo testing. Covering both the UVB and UVA spectral regions, the system automatically scans from 290 to 400 nm, accumulating and storing data at intervals of 1, 2 or 5 nm. The monochromatic protection factor (MPF) is determined for each of the selected wavelengths and is used to calculate the SPF value, using solar irradiance and erythemal constants that are programmed into the software but which can be easily modified.

Liquids, creams and gels are applied in small "dabs” or "spots” to the Transpore Tape^® or other substrate, with the pipette supplied with the system. The substrate is placed on an open metal frame. The sample is spread lightly and evenly over a 55 cm² area at 2 μl/cm², equivalent to in-vivo testing. Sprays and sticks are applied directly to the substrate material, just as they would be in actual use. Quartz plates are available for sprays and difficult samples.
