AUTOPOL V PLUS Polarimeter

This is the same as Autopol V and has additional featues such as Hastelloy sample compartment, Hastelloy sample tube, comes with a NIST traceable quartz plate with three rotations - positive, negative & low rotations and each rotation would be with a NIST certificate.

The AUTOPOL V® has the validation tools and features to satisfy today’s global pharmaceutical companies, including: instrument level 21CFR Part 11 compliance, NIST traceable calibration standards and a global list of installations. Rudolph Research has thousands of satisfied customers who praise the Autopol® V’s quality, accuracy and reproducibility.

The AUTOPOL V Plus Advantage

  • 6m HCl acid resistance: Silco Steel coating on the chamber temperature transfer surface and a Hastelloy measurement cell with NIST certificate certifying optical path length.
  • To meet the FDA’s latest position on measurement bracketing, the Autopol® V Plus comes with a NIST traceable quartz plate with three rotations: +0.998° Arc, +10.998° Arc, -10.000° Arc. Each rotation has a NIST certificate.
  • Windows based navigation architecture is so intuitive that most operators will never read the manual. But should you wish to reference the manual, it is stored right on the Autopol® V Plus’ internal memory.
  • Available with automated sampling.
  • Three USB ports allow quick and easy connection to a mouse, keyboard, printer, bar code scanner, or memory stick. One USB port is located on the front of the unit (shown above) and two USB ports are located on the back of the unit (shown below).
  • Ethernet Port for Network Cable Connection
  • Internet access allowing connection to Rudolph’s service department for remote testing and diagnostics
  • Connect to any Windows® based printer via USB or direct to the server via Windows® Print Library
  • Save measurement data direct to your Network/Server
