The Autopol® VII For High Throughput Pharmaceutical Laboratories

High Accuracy Polarimeter with Industry Leading Automated Sample Loading
The Industry Standard Polarimeter
The Autopol® VII combines a pharmaceutical level Polarimeter with fully automated sample loading capability, a perfect answer for high throughput labs that demand accuracy and, reproducibility, combined with versatile sample loading, cell cleaning, rinsing, and drying.

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

The Autopol® VII offers Automated NIST Traceable 3 point validation combined with fully Automatic TempTrolTM Temperature Control
The Autopol® VII has built-in NIST Traceable Quartz plates to automatically perform a 3 rotation validation on the Autopol VII. To validate the instrument simply press a button to begin the validation routine. Using the on-board quartz plate standards the instrument will perform and record the results of a full 3 point calibration at all wavelengths at the correct temperature.

Built-In quartz plates will perform a 3 point validation automatically.



The Autopol® VII Uses Rudolph’s Exclusive TempTrol™ Electronic Temperature Control System

The USP <781> requires optical rotation measurements at 25°C ±.5°C (Unless another temperature is specified) The European Pharmacopoeia requires optical rotation measurements made at 20°C ±.5°C (Unless another temperature is specified) Whatever your temperature control needs are, the Autopol VII exclusive TempTrol™ System (Patent No. 6,717,665) makes your measurement in a few minutes without a water bath or any type of water circulation.


Integrated sample loading with the flexibility you need

Automated filling, cleaning, and rinsing

The Autopol VII with integrated sample loading
can be configured to automate a wide range of sample viscosities. Perfect for high throughput laboratories looking to increase productivity. By automating sample loading user time is saved. The method ensures samples are loaded properly and the correct cleaning and
rinsing sequence is performed. The Autopol® VII with integrated automated sample loading is ideal for busy Pharmaceutical laboratories where sample
handling is discouraged.
