Description

The Lasany LI-P702 Automatic Polarimeter with Touchscreen is a sophisticated, high-precision analytical instrument designed to measure the angle of optical rotation of polarized light as it passes through optically active substances. Engineered for laboratories that require accurate, repeatable, and operator-friendly polarimetric analysis, the LI-P702 combines fully automatic measurement with an intuitive touchscreen interface and comprehensive built-in software—eliminating the subjectivity of traditional visual polarimeters. Manufactured by Lasany International under ISO 9001:2015 and WHO-GMP standards, this digital automatic polarimeter supports four key measurement modes—optical rotation, specific rotation, sugar (International Sugar Scale Z), and concentration—making it an indispensable instrument for pharmaceutical quality control, food and beverage analysis, chemical research, and academic laboratories. Its automatic 6-repetition measurement with average value calculation, 100 mm/200 mm sample tube compatibility, multipoint automatic calibration, and built-in data management software ensure that every measurement is traceable, documented, and audit-ready. The LI-P702 is Lasany’s definitive touchscreen polarimeter for modern analytical laboratories—trusted across India and exported globally.

Why choose the LI-P702?

Fully automatic — zero visual interpretation required — unlike traditional visual polarimeters where results depend on the analyst’s ability to judge the shadow field, the LI-P702 measures optically and electronically, delivering objective, operator-independent optical rotation values every time.

Statistically reliable results with 6× auto-repetition — the built-in automatic repeat-measurement function takes six readings and calculates the mean, reducing random measurement error and providing statistically validated results without any extra analyst effort.

Comprehensive software for data integrity—inbuilt reporting software generates PDF and Excel outputs, supports LIMS integration, and enables remote monitoring, meeting the documentation needs of pharmaceutical and regulated food laboratories.

Versatile four-mode measurement — the ability to switch between optical rotation, specific rotation, sugar (°Z), and concentration modes in a single instrument eliminates the need for multiple dedicated instruments, reducing capital expenditure for multi-application laboratories.

Certified quality, backed by Lasany expertise—manufactured under ISO 9001:2015 and WHO-GMP standards with CE certification and supported by Lasany International’s specialist technical and after-sales team across India and global export markets since 1998.
