High speed circle Polarimeter model NH8 - Automatic, Polartronic, tubes

Automatic Circle Polarimeter - UniPol L

Features of the Polartronic UniPol

Outstanding value - excellent price/performance unit suitable for many applications
Highly accurate because of the direct linking of the optical analyzer and angle encoder
High speed - excellent response time between readings resolves in 5 seconds or less.
Short measuring time no need to return to zero position for new measurements
Faster operation 5 degs/sec response time
Graphic LCD displays ID, rotation temperature, date.
Displays levorotory samples (glucose)
Built in RS232 interface

UniPol L series
Full Circle Polarimeters
The UniPol series polarimeters are very similar to the research resolution polarimeters in quality and range but they have been designed for more routine applications requiring only a 0.01 degree accuracy. Like the high resolution version the UniPol determines the optical activity of a solution by means of a rotating analyzer linked to an optical encoder. They include the Schmidt and Haensch patented direct linking of the polarizing analyzer to the optical position encoder, ensuring constant resolution throughout the range, high accuracy and repeatability. Also these polarimeters are up to 5 times faster than competitive instruments. The UniPol series are automatic full circle polarimeters designed for continuous measurement operation. It is never necessary to return to a start or zero position in order to initiate a new measurement. The UniPol series work with standard Polarimeter tubes and continuous flow tubes. You can also order special tubes for temperature measurement and small micro-tubes for precious samples. There are several models to choose from suitable for routine lab work, and saccharimetry. These instruments are ideal for quality control and research because of their outstanding specification and performance at a reasonable price.

Bright clear LCD display shows absolute rotation in degrees or sugar degrees or Z*2 sugar degrees. When a new sample is placed in the sample compartment the instrument automatically finds and displays the new reading within a couple of seconds. Scales are changed with the up down arrows. 'Reset' zeros the instrument when you first switch on.

The NH8 includes a ready to use RS232 data port which enables transmission of the data to a PC or serial printer.
