Description Overview GAOTek APM Digital Automatic Polarimeter is an instrument for measuring the rotation of substances. The concentration, content and purity of the substance can be determined by spectrophotometry. Digital Automatic Polarimeter has built-in Peltier precise temperature control system, which can meet users’ requirements for testing at constant temperature. The built-in automatic calibration program is optional, and the standard automatic calibration tool can be automatically calibrated from -45 degrees to 45 degrees, which fully meets the user’s demand for controllable measurement accuracy in daily operation. The multi-level authority management of digital automatic polarometer can meet the audit tracking. Features Built-in Parpaste temperature control, improve accuracy and stability There are rotation/specific curl/concentration/sugar degree and custom mode LED cold light source instead of the traditional sodium light lamp and halogen tungsten lamp Compliance with 21CFR Part 1 audit trail, pharmacopoeia and electronic signature; Support network printing, support data statistical retrieval Multi-level authority management, authority can be freely configured 10-inch touch color screen, user-friendly operation interface The system comes with an automatic calibration system. Comply with GLP GMP certification Technical Specifications Measurement Mode Rotation, specific curl, concentration, sugar content and custom formula Light Source LED cold light source high precision interference filter Working Wavelength 589.3 nm Test Function Single, multiple and continuous measurement Measuring Range Optical rotation ± 90 ° Sugar ± 259 ° for Z Minimum Reading 0.001°(0.0001°Optional) Accuracy ± 0.002 ° Repeatability (Standard deviation s) 0.002° (Optical rotation) Temperature Control range 50 °F to 140 °F (10 ℃ to 60 ℃) (Peltier) Temperature Resolution 32.01 °F (0.01 ℃) Temperature Control Accuracy ±32.03 °F (±0.03 ℃) Display Method 8-inch TFT true color touch screen Standard Test Tube 7.87 in (200 mm), 3.94 in (100 mm) ordinary type, 3.94 in (100 mm) temperature control type (optional Hastelloy alloy temperature control tube of various lengths) Transmittance 0.01% Data Storage 64 GB
