Brix Isn’t Just Sugar
How Refractive Index Measurement Supports Quality Across Industry Brix: A Familiar Term with a Much Broader Meaning. Ask someone in the food industry what “Brix” means, and the answer will likely be “sugar content.” While that answer is rooted in history, it no longer tells the whole story. Today, Brix is one of the most […]
Critical USP <781> Optical Rotation Changes Every Lab Should Know
Executive Summary USP Chapter <781> Optical Rotation was officially revised on November 22, 2024. The new requirements introduce significantly more detailed guidance for the qualification, calibration, and ongoing verification of polarimeters used in pharmaceutical laboratories. The changes affect: For pharmaceutical manufacturers, contract laboratories, and quality control groups, compliance now requires a more structured approach to […]
The Rudolph R837D: Fast, Flexible Automation for Modern Analytical Laboratories
Laboratories today face increasing pressure to improve throughput, reduce operator variability, maintain regulatory compliance, and handle increasingly complex sample types. While high-capacity automation systems dominate discussions around laboratory efficiency, not every laboratory requires a 50- or 100-position carousel autosampler. Many labs prioritize flexibility, rapid setup, ease of use, and the ability to process difficult samples […]
Manual vs. Automated Laboratory Sample Handling: Costs, Labor & ROI
A Comparative Analysis of Manual vs. Automated Workflows in Liquid Product Laboratories Introduction Laboratory sample automation, why? Laboratories analyzing liquid-based products—such as flavors, fragrances, beverages, liquid foods, and nutraceuticals (including oils and lotions)—are under constant pressure to deliver accurate, repeatable, and compliant results. Each sample often requires multiple analytical measurements to ensure product quality and […]
