Automatic Polarimeter - Digital Optical Rotation Meter - ±45° Range - 589 nm LED Source

The Master Science Automatic Polarimeter measures the optical rotation of optically active substances without manual end-point matching. From that reading it derives concentration, content, purity, sugar content and specific rotation.

The series has five models. All read ±45° at 589 nm from an LED source through an interference filter. They differ in measuring modes, display, accuracy and temperature control, so a laboratory can pick the level it needs for sugar, pharmaceutical, food or chemical work.

Key Benefits

• No visual matching: the Master Science Automatic Polarimeter finds the rotation angle itself.
• More reliable averages: up to six automatic repeat readings.
• Dark samples measured: RMS calculation on the 2P and 1P.
• Lamp lasts for years: LED in place of a sodium lamp.
• Temperature held at the cell: Peltier control on the 2P.
