DigiPol Automatic Polarimeter

Drawell Digipol-P series polarimeter is an instrument for measuring the rotation of substances. The concentration, content, and purity of the substance can be determined by spectrophotometry.

Drawell Automatic Polarimeter has a built-in Peltier precise temperature control system, which can meet users’ requirements for testing at a 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 Drawell automatic polarimeter can meet the audit tracking.

Fields of Use

  1. Automatic polarimeter is widely used in medicine, food, the organic chemical industry, and other fields.
  2. Agriculture: analysis of ingredients such as agricultural antibiotics, agricultural hormones, microbial pesticides, and starch content of agricultural products.
  3. Medicine: analysis of antibiotics, vitamins, glucose, and other drugs, the pharmacological study of Chinese herbal medicine.
  4. Food: sugar, monosodium glutamate, soy sauce, and other production process control and finished product inspection, food sugar content determination.
  5. Petroleum: analysis of mineral oil, monitoring of petroleum fermentation process.
  6. Fragrance: analysis of essential oils.
  7. Health services: analysis of clinical diabetes in hospitals.
