Model SPF-290AS Automated UV Transmittance / SPF Analyzer

Solar Light’s versatile SPF-290AS UV Transmittance / Sunscreen Protection Factor Analyzer is an integrated turnkey UV spectrophotometer, designed and optimized for the determination of SPF values on a variety of sunscreen and cosmetic products, as well as materials testing. This self-contained, attractive desktop unit reduces the need and associated 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 5nm. 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.)

The SPF-290AS is the perfect choice for quick, efficient, and accurate analysis of:

• Liquids

• Lotions

• Creams

• Sprays

• Gels

• Powders

• Emulsions

• Textiles

Validation Kit Included

An SPF-290AS Validation Kit is included with each analyzer and comes complete with a Comprehensive Test Plate. The Comprehensive Test Plate contains several optical filters that are measured by the SPF-290AS, and the results are compared to NIST-traceable factory measurements. This feature is designed to provide a clear understanding and validation of how your SPF-290AS analyzer is performing against factory measurements for optical density, wavelength accuracy, and correlation to in-vivo testing whenever desired. Equipped with this tool, users will not spend time performing tests on an analyzer that is in need of repair, nor will they spend money for repairs that are not necessary. The SPF-290AS Validation Kit includes:

• Storage case

• 10 syringes with tips, 1 ml, disposable

• PMMA plates, 50 x 50 mm, 5μ roughness, sample set of 3

• Sample holder for 50 x 50 mm PMMA plates

• Calibration Filter Plate assembly

• 1 oz jar of Homosalate Standard

• 1 oz jar of COLIPA Standard

• Factory calibration data

Depending on your intended testing methods, additional boxes of two hundred PMMA plates in either 2μ roughness or 5μ roughness are available optionally. We also offer 3M™ Transpore™ tape and Transpore tape holders for performing less demanding measurement data collection.

High Correlation with In-Vivo TestingThe high correlation between the SPF-290AS in-vitro measurements and in-vivo test results provides confidence that the analyzer will be a reliable guide to product performance. The SPF-290AS delivers reliable results on the most difficult samples. An easy-to-use testing methodology, combined with reproducible results, opens the door to efficient and low cost experimental design techniques for formulation optimization. This will result in faster formulation and lower development costs due to a reduction in the need for extensive in-vivo panel studies.

Korea Food & Drug Administration Qualify the SPF-290S as an Alternative Method to in-vivo Testing“The results of this study for correlation between the in-vivo SPF and in-vitro SPF measured using SPF-290 analyzer are…..The in vitro SPF test method will be used as an alternative method for in vivo SPF and a new test item for quality control sunscreens.”– Drug Evaluation Department, Korea Food & Drug Administration, 5 Nokbun-dong, Eunpyung-gu, Seoul, Korea

The Complete SPF-290AS SPF Analyzer / UV Transmittance Analyzer and Computer Includes:

• Motorized and automated X-Y sample stage and control module for Hit-and-Forget measurements of up to 12 discrete sample positions

• 175W CW Xenon Source

• Color Compensating Filter

• PMT Detection Module – The photomultiplier provides extremely high sensitivity and ultra-fast response. Photomultiplier tubes (PMT) have high bandwidth and noise-free gain on the order of a million. This makes PMTs ideal for the detection of extremely low light levels as required in SPF measurements.

• Precision scanning monochromator with stepping motor and controller

• Computer hardware and software as described above

• Box of 25 syringes with tips (1 ml disposable)

• Validation kit

• Factory calibration data

• Complete instruction manual

• Audio/ Visual training

• Available for use with 100 VAC / 50 Hz, 110 VAC / 60 Hz, or 220 VAC / 50 Hz. Specify at time of order.

Fully Automated Multi-Point Sampling – Saves Time and Money!

While other analyzers are limited to single position measurements, requiring the operator to manually reposition the sample for each measurement position, the SPF-290AS enables simple push button Hit and Forget Automated Sequencing of up to 12 sampling positions such as required in the COLIPA methods. With Hit-and-Forget Automated Sequencing, this time saving feature lets the operator walk away from the analyzer and work on other tasks while the SPF-290AS completes the methods’ required multiple position measurement routine automatically.

Two modes of automated operation:

Data can be acquired in approximately 20 seconds. Results displayed in easy to read format.

Autoscan

Autoscan mode offers two methods of choosing up to 12 sampling locations. The operator can either specify the positions to be read or the computer can generate them randomly. Once set, the operation, data collection and reporting are performed automatically. The stage moves the sample on the holder into the light beam, takes the measurements, moves to the next position and continues until all the measurements have been completed.

Automated “Hit and Forget” operation:

• Improves repeatability and accuracy of measurements

• Eliminates the need to manually reposition the sample for each measurement and allows operators to perform other functions

• Enables time based photo-stability measurements

• Get to market sooner

• Reduces the cost of testing

• New sample pattern for PMMA plates

Photo-Stability

Time-based measurements monitor the SPF values for a sample at a user-specified position against time. The effects of drying and exposure to air and light on a sample can be easily evaluated making it particularly suitable for photostability testing. The system’s computer provides a controlled repeatable time base for measurements.
