Rudolph Quartz Control Plate Calibration Standard

The Rudolph A700-2-1 Quartz Control Calibration Standard is a high-precision reference material designed for the calibration and verification of polarimeters and saccharimeters. This standard is a quartz plate that provides a stable, reproducible optical rotation value.

Quartz is used because its optical rotation is highly stable and dependent only on temperature, making it an ideal primary reference standard. The "A700-2-1" designation refers to a specific, certified optical rotation value that is precisely measured and verified, ensuring its reliability for instrument calibration. This standard is essential for laboratories in the pharmaceutical, chemical, and food industries to meet stringent quality control requirements for measuring the concentration and purity of optically active substances like sugars, amino acids, and chemical enantiomers.
