AUTOMATION - COMPUTER CONTROLLED SAMPLING STAGE
NOW redesigned with all electronics and drivers on board for a smaller footprint.
The Computer Controlled X-Y Sampling Stage is to:
reduce the overall cost of testing,
free technicians for other tasks,
improve the repeatability and accuracy of measurements, and
facilitate photo-stability testing

There are two modes of computer controlled operation:
programmed reading of up to 12 locations (Autoscan), and,
time based measurements (photo-stability)
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.
Time-based (photo-stability) 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.
Computation of statistics for multiple assays is provided by the software.

Correlation between the SPF-290S in-vitro and in-vivo SPF testing
The high correlation between the SPF-290S's in vitro measurements and in vivo test results gives you confidence that the instrument will be a reliable guide to product performance.
The chart shows data comparisons for a variety of commercially available products including:
physical sunscreens
sprays
waterproof sunscreens and stick formulations
The SPF-290S can provide 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 cost due to a reduction in the need for extensive in-vivo panel studies.
