Rapid Moisture Analysis for Medical Devices

Reduce defects and conserve material

Moisture content analysis for medical devices has never been easy. The resins are sophisticated and very expensive, the customers are demanding, and a minuscule cosmetic defect can mean the difference between thousands of dollars of saleable finished goods and scrap. When working with the complex, high-volatile-content materials that make up modern medical devices, every part per million counts, and every gram of resin counts. That’s why Computrac® designed the Vapor Pro® XL.

The Vapor Pro XL is an alternative to Karl Fischer titration that delivers accurate, precise moisture-specific measurements as low as 10 parts per million and does it all with no chemicals, no expensive glassware, and no special expertise needed. Its small sample size—as low as 0.25 grams for very low moisture plastics—makes it ideal for high value resins often used in medical devices. If you currently use Karl Fischer titration to test for moisture in your high value resins, give us a call. Our experienced team of analytical chemists and applications consultants will help you discover how to improve your testing accuracy and throughput while reducing overall testing cost.
