The Autopol® V Plus Polarimeter features Automatic Calibration, allowing users to quickly verify instrument performance with minimal effort. By automating the calibration process, laboratories can improve workflow efficiency, reduce the potential for user error, and maintain confidence in measurement accuracy.
The Rudolph Autopol V PLUS validates linearity using a high rotation Quartz Plate, Low Rotation Plate, and both plates together, automatically performing this check across up to six wavelengths. Validation results are conveniently stored for future reference. Fully automatic operation also makes frequent validation practical, because your measurements are only as reliable as your last validation.
Designed for regulated and high-throughput environments, the Autopol V Plus lets laboratories spend less time on routine instrument checks and more time producing results.

Many beverage laboratories struggle with one common issue during density testing: bubbles in the sample tube. Even small bubbles can impact measurement accuracy, create repeat testing, and slow down production workflows.
Rudolph’s DDM 2911 PLUS Density Meter helps solve that problem with VideoView™ bubble detection technology. Operators can visually confirm proper sample loading directly on the instrument, helping reduce sample errors before a measurement is even taken.
For beverage, pharmaceutical, petroleum, and chemical laboratories, this means:
• Improved confidence in measurement results
• Reduced retesting and wasted samples
• Faster workflows and better operator consistency
• More reliable density and concentration measurements
The DDM 2911 PLUS is designed to support laboratories that require both speed and precision while maintaining compliance with industry standards and quality requirements
