The Vapor Pro® XL (VPXL) Autosampler is the latest in moisture-specific analysis technology offering accuracy, precision, flexibility, and automation to test up to 16 samples with individual test profiles. The VPXL Autosampler’s advanced moisture analysis capabilities make it a chemical-free alternative to Karl Fischer titration. Its compact size and upgraded features make the VPXL Autosampler ideal for nearly any application where test automation and increased throughput is needed.
Features and Benefits
- Zero Chemical Reagents: The Vapor Pro® XL offers moisture specific analysis that correlates well with Karl Fischer without the hassle or expense of hazardous chemical reagents, costly glassware or time-consuming maintenance.
- Versatile: The VPXL Autosampler is ideal for nearly any application where the Karl Fischer titration is used. Its ability to individualize sample test profiles make it perfect for all industries ranging from plastics and petroleum products to pharmaceuticals and chemicals. The maximum testing temperature can be set to 300°C. It also allows for improved control over testing temperatures across the range of the instrument.
- Automation: The VPXL Autosampler provides the ability to quickly and automatically test up to 16 samples, dramatically increasing throughput in a
compact instrument. - Stepped Temperature Testing: The VPXL Autosampler offers stepped temperature testing capabilities that make method development easier than ever before.
- Flexible Ending Criteria: The user-adjustable ending criteria optimizes test results and performance for any unique application.
- Data Storage: The VPXL Autosampler stores up to 250 test programs and retains the previous 1000 test results and 100 test graphs. Users can view and select past test results for statistical analysis and test various samples with ease.
