Suntest : Lightfastness and Weathering test chamber
Suntest : Lightfastness and Weathering test chamber
SUNTEST instruments are compact material test chambers for accelerated lightfastness and weathering testing based on filtered xenon lamp technology. All SUNTEST chambers offer a horizontal test plane which is particularly useful for testing 3-D specimens. Lightfastness testing aims at testing a material under solar radiation and temperature only – Weathering testing adds water and moisture to the test. Inside a SUNTEST, the applied stresses are intensified in such a way that allows you to see the material property changes which would occur over the course of months or years in real time. Property changes such as color fading, embrittlement, cracking become visible within weeks.
 
 
SUNTEST CPS+
 

The Atlas SUNTEST CPS+ is the small entry model. CPS+ is the most widely used benchtop xenon instrument in the world. Its compact design, easy handling and proven reliability make it the ideal quality control and R&D screening device for a variety of industries, such as plastics, packaging, pharmaceuticals, cosmetics, and many more.

The chamber has a 28x20cm test area suitable for small test specimens. The applications are broad, ranging from UV-stability testing, studying the light stability of chemicals (colors, scents, additives), determining sun protection factors of skin care products, or product shelf-life (ASLT). The SUNTEST CPS+ is the practical introductory benchtop solution for those new to light stability and weathering testing.

The practical benchtop xenon lamp unit with useful accessories to tailor your SUNTEST towards your needs. Here you see the SunCool chiller (for pharmaceuticals / cosmetics), the SunTray sample exchanger (for in-vitro SPF), and the SunFlood immersion unit ( for coatings / sealants).


Benefits:

  • Premium simulation of solar radiation according to CIE85 reference sun
  • Optional simulation of window glass filtered daylight, and others
  • User friendly interface with 11 selectable languages
  • Pre-programmed 300 hour tests for Quick-start setup or as templates for custom tests
  • Black Standard Temperature Sensor (BST) according to ISO 4892-1
  • Automatic control of irradiance for various testing needs


Accessories:

  • SunFlood immersion unit for testing materials under extreme moisture conditions
  • SunCool chiller for testing at low temperatures (e.g. cosmetics)
 
  
     
 
SUNTEST XLS+
 

The Atlas SUNTEST XLS+ is an advanced benchtop xenon tester with state-of-the-art UV-control for reliable R&D screening tests. The benchtop design is suitable for every laboratory, equipped with optional accessories such as water spray, immersion and refrigeration, expanding your testing capabilities and offering easy ways to customize it to your needs.  It comes standard with a 1100 cm2 exposure area, suiting multiple flat or 3D samples. The Atlas SUNTEST XLS+ provides about twice the exposure area of the CPS+. It offers the tallest test chamber making it especially useful for 3-D specimen testing. Additionally, it complies to various ISO, ASTM and ICH industry standards. The XLS+ can apply water either by spraying or flooding. A touch screen makes it simple to program and the Ethernet interface makes network integration easy. The SUNTEST XLS+ is widely used in pharmaceutical R&D and accelerated weathering testing of polymers, coatings and sealants.

The SUNTEST XLS+ is used to check for property changes of materials and products caused by sunlight, temperature and moisture in a short period of time. The aging which, outdoor or indoor, may take place over months or years, such as fading, yellowing or loss of strength, can often be simulated within weeks inside a SUNTEST. It is widely used in pharmaceutical R&D and accelerated weathering testing of polymers, coatings and sealants.
 

Benefits:

  • Premium simulation of solar radiation according to CIE85 reference sun
  • Simulation of window glass filtered sunlight or artificial supermarket light
  • Best-in-class chamber design for testing 3-D specimens
  • Easy-to-use touch screen user interface with 13 selectable languages
  • Pre-programmed standards for Quick-start operation
  • Black Standard Temperature Sensor (BST) according to ISO 4892-1
  • Automatic control of irradiance for various testing needs


Optional Accessories:

  • SunSpray unit for water spray during weathering testing
  • SunFlood immersion unit for testing materials under extreme moisture conditions
  • SunCool chiller for testing at low temperatures (e.g. Pharmaceuticals, Beverages)

 

 
  
     
 
SUNTEST XXL+ FD
 

The Atlas SUNTEST XXL+ FD is a large state-of-the-art xenon flatbed instrument. It’s completely target designed to meet the testing needs of the FMCG industry, such as drinks, foodstuffs, personal care or household products. XXL+ FD enables consumer goods manufacturers to test their products realistically within very short test times, typically with acceleration factors between 10-30 versus real time. It’s for reliable qualification of stable product formulations, determination of appropriate packaging materials, and supporting product shelflife claims.
