Introduction
An automatic polarimeter is an analytical instrument used to measure the optical rotation of a solution, which is the rotation of the plane of polarized light by optically active substances, such as sugars, amino acids, and pharmaceuticals, and it is used in the food, pharmaceutical, chemical, and research industries for quality control and analysis. The polarimeter consists of a light source that produces polarized light, a sample cell that holds the solution, a polarizer and analyzer, and a detector; in operation, the polarized light passes through the sample, and the optically active substances in the sample rotate the plane of polarization, and the analyzer is rotated to measure the angle of rotation, which is proportional to the concentration of the optically active substance, according to the specific rotation of the substance; the automatic polarimeter performs the measurement automatically, with the analyzer rotated by a motor and the angle measured and displayed, and it provides rapid and accurate measurements, with features such as automatic zeroing, temperature control, and data management, and it measures the optical rotation in degrees, and the specific rotation can be calculated; the polarimeter is used with various wavelengths, typically the sodium D line at 589 nm. Automatic polarimeters are used for measuring the concentration of sugars in foods and beverages, for analyzing the purity and concentration of pharmaceuticals, for measuring the optical rotation of chemical compounds, for quality control, for research, and for many other applications, and they are available as benchtop instruments with various features. With their precise measurement of optical rotation, automatic polarimeters are essential for the analysis of optically active substances.

FAQ
Q1: What scenarios is this polarimeter used for?
A: It measures optical rotation and derived concentration or purity for pharmaceuticals, sugars and chiral chemicals automatically. Customers in related industries rely on it for routine and quality-control work, and we can match the unit to your intended use.
Q2: What standards does it comply with?
A: It follows ICUMSA for sugar, pharmacopeial polarimetry, related ISO and GB/T standards, with calibration verified. We confirm the stated performance during final inspection and can supply a certificate of conformity together with supporting documents for audit purposes.
Q3: What is the warranty?
A: The polarimeter carries a 12 to 24 month warranty covering the instrument. Tubes and lamps are wear parts. Damage from spills or misuse is excluded.
Q4: Is it hard to operate?
A: Routine measurement is simple after training: fill a tube, select the method and read. We provide a manual and training.
Q5: What is the lead time?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is calibration required?
A: Performance should be verified periodically using calibrated reference standards, with results logged in the equipment record. Most users perform this check every 6 to 12 months or according to their internal quality schedule. We provide the procedure, reference materials and formal calibration service if required.
Q7: Are consumables universal?
A: Tubes are standard or model-specific, while standards are certified. Ongoing cost is minimal.
Q8: Can it be customized?
A: Yes, several configurations are available. Options include wavelength, temperature control, autosamplers and data systems. We can discuss further custom requirements, confirm feasibility and advise any effect on the schedule before the order is confirmed.
Q9: Is installation included?
A: No installation is required. The unit is delivered fully assembled and factory tested, so you only need to place it on a level surface, connect power and follow the quick-start guide. An illustrated manual and setup video are included, and our engineers provide remote guidance if needed.
Q10: What samples are compatible?
A: It handles clear optically active liquids within range. It is not for turbid samples, non-optically-active compounds, or samples beyond tube and temperature limits.
