Atlas® introduces new sample table for SUNTEST® CPS/CPS+ instruments
Linsengericht-Altenhaßlau, October 2008, Atlas, the global leader in lightfastness and weathering testing has developed SunTray - a new sample table for the SUNTEST CPS/CPS+ instruments.
In 2007, the COLIPA organisation has issued a new guideline: Method for the in Vitro Determination of UVA Protection Provided by Sunscreen Products[Edition 2007a]
The method describes how sunscreen products are exposed in Atlas SUNTEST CPS/CPS+ and XLS/XLS+ instruments. The test time of each individual sample is calculated based on the type of sunscreen product and amount of product on the test substrate. Due to the frequent exchange of samples the COLIPA method suggests to take samples out of the SUNTEST instrument without stopping the test program and switching off the instrument. This procedure, however, leads to unacceptable exposure of the operator to xenon light.
Atlas is pleased to introduce a new sample table, the SunTray, which enables the operator to remove samples from the SUNTEST CPS/CPS+ instruments without switching off the lamp based on the Colipa test method.
The sample table consists of a drawer that includes a holder in which six samples can be placed. The samples are positioned into the normal sample plane by turning the knob of the drawer. The apertures for the six samples in the holder have a standard size of 50 x 50 mm. In addition, a special sample holder is available for calibration purposes. The standard XenoCal calibration sensors fit into the SunTray drawer for regular measurement and calibration of the light source.
The SunTray sample table is for SUNTEST CPS and CPS+ only and available with immediate effect. For more information please visit www.atlas-mts.com.
