Description
Lasany LI-P702 Digital Automatic Polarimeter for Professional Laboratory Applications
The Lasany LI-P702 Digital Automatic Polarimeter is an analytical laboratory instrument designed to measure the optical rotation of optically active substances. It supports professional laboratory testing, scientific research, product analysis, and quality control applications in pharmaceutical, chemical, food processing, sugar, and beverage industries.
Featuring a colour touchscreen, automatic measurement functionality, and multiple analytical modes, the LI-P702 allows users to measure optical rotation, specific rotation, sugar degree, and concentration. Its automatic repeat-measurement function takes six readings and calculates an average, supporting consistent laboratory workflows. The instrument also offers USB and RS-232 connectivity for compatible external devices.
Key Features
- Four measurement modes: Optical rotation, specific rotation, sugar degree, and concentration.
- Colour touchscreen: Provides an intuitive interface for operating the instrument and viewing results.
- Automatic repeat measurement: Performs six measurements and calculates the average value.
- LED light source: Uses a 589 nm wavelength for standard polarimetric analysis.
- Optical rotation range: Measures optical rotation within ±45°.
- Sugar degree measurement: Supports readings up to ±120°Z.
- Sample tube compatibility: Supports 100 mm and 200 mm sample tubes.
- Data connectivity: USB and RS-232 interfaces for supported data transfer.
- Dark sample testing: Designed to measure samples with low light transmittance, subject to sample suitability.
