ADP440 Polarimeter
The ADP440 is single wavelength, high accuracy polarimeter suitable for use in
many applications and is especially suited for use in pharmaceutical laboratories where compliance with Pharmacopoeia1 is required. New optics featuring a ‘no maintenance’ yellow LED and interference filter together with a photodiode detector allows reading of samples of up to 3.0 OD. The instrument has both angular and sugar scales (ISS) and can be programmed with user scales as well as industry standard methods for displaying concentration and specific rotation directly.
ADP440 – Operation
As the instrument is continually reading, all that is required is for the operator to place the sample tube in the measurement chamber and read the result. Four push buttons on the instrument keypad allow for MENU setup, ZERO calibration, METHOD selection (or display MODE if no methods are being used) and PRINT. A security system using passwords protects against deliberate or accidental misuse, which can be expanded to allow conformance with the technical requirements of FDA regulation 21 CFR Part 11. User Acess is provided by keypad entry or RFID user assigned ‘tags’.
The ADP440 continually displays the measured reading, providing the operator assurance of measurement and
