Automated Pharmaceutical Saccharimeters 

The Autopol 880 Plus and Autopol 880T Plus are the latest most advanced model, developed and tested in conjunction with labs testing pharmaceutical grade sugars. These labs require precise temperature control yet still want flow through cell type operation. These units are only suitable for air-conditioned modern laboratories.

These dual wavelength saccharimeters are capable of measuring at both 589 nm and 880 nm. The 880 nm ICUMSA approved near infrared wavelength allows measurement of dark sugar factory juices, while the purity mode allows simultaneous measurement and display of Purity, Brix and POL.

Dual Wavelengths

The most important feature of the Autopol 880 and 880T Plus is the ability to measure at two wavelengths: 589 nm and 880 nm (NIR). Select 589 nm for conventional analysis using chemicals or lead clarifiers, or select 880 nm for polarimetric sugar measurements in the near infrared (NIR).

880 nm is above the absorption level of most dark sugar factory solutions allowing measurement of filtered but non-lead clarified juices. The dark sample measurement bar gets darker in proportion to the darkness of the sample being measured. When the bar is completely dark the instrument has reached its measurement limit.

Dilution and Cell Length Correction

Whether your sugar analysis requires a 25mm, 50mm, 100 mm or 200 mm cell, whether you use 1/2 normal (13g/100ml), 1/4 normal (6.5g/100ml) or full weight sugar solutions, the AUTOPOL® 589, 880, 880 Plus and 880T saccharimeters provide the correct multiplier to display the reading as if the sample were prepared as a 1 normal solution in a 200 mm optical pathlength cell.

Automatic Saccharimeter Calibration

Calibrating the Autop[ol is quick and simple. First, place a quartz control plate calibration standard on the optical rails and enter the quartz plate value in the appropriate window. Then enter the temperature to correct the measurement to either the ICUMSA standard temperature of 20°C or the Tropical reference temperature of 27.5°C. Finally press Save and the calibration is complete.

Automatic Temperature Correction

Utilizing the temperature probe located in the measurement compartment, temperature correction to 20ºC, 27.5ºC or other user defined temperature is performed easily and automatically by the Autopol 880 Plus and Autopol 880T Plus .. The probe can be inserted into all 14 style, 40T style, 41T style and 33 style measurement cells.
The Autopol displays the temperature source and type of correction. Utilizing factory programmed temperature coefficients the Autopol can make the following types of temperature corrections:

 

  • A 30° C sucrose sample can be measured by the temperature probe and corrected to 20°C or 27.5°C or a customer defined temperature
  • A 29°C sucrose sample in a Type 14 center fill glass cell can be measured by the temperature probe inside the saccharimeter sample chamber and corrected to 20°C
  • A Quartz Plate measured at 25°C by the chamber temperature probe and then automatically corrected to 20°C

Optics

No matter which Autopol saccharimeter you choose it will feature the same high quality optics. While other manufacturers use Polaroid plastic dichroic sheet polarizers, Rudolph Research employ Glan Thompson Calcite polarizers in all its models. High quality polarizing prisms are important because they are two of the most critical optical components in a saccharimeter. Polaroid polarizers are made of a polymeric plastic where the molecules are stretches and oriented in a specific direction so as to linearly polarize light. These types of plastic sheet polarizers are cheap, vulnerable to heat and warping, deteriorate from moisture and have greater light absorption than Calcite polarizers. In many cases the plastic polarizers must be replaced in as little as 3 years whereas Rudolph guarantees its prisms over the life of the Saccharimeter. Glan Thompson calcite polarizers are comprised of a carbon crystalline structure similar to diamond and have excellent light transmission characteristics. The quality of these prisms is such that they are guaranteed over the life of the saccharimeter.

TempTrol

The patented TempTrol technology eliminates the need for a water bath, allowing push-button temperature control of the 100mm cell, 200mm cell or quartz control plate. Set the temperature, push “measure” and walk away. The Autopol will heat or cool to a predefined temperature and then provide you with the result in one easy step. The TempTrol™ system will accurately control your sample temperature to within ±0.2°C. This is particularly important for laboratory work when measuring pharmaceutical grade sugars.
