Description
The Lasany LI-285 Microprocessor UV-VIS Single Beam Spectrophotometer with Software is a precision analytical instrument engineered for accurate, reliable spectrophotometric analysis across an exceptionally wide range of scientific and industrial applications. Manufactured by Lasany International under ISO 9001:2015 certification in Panchkula, Haryana, the LI-285 employs a CT grating monochromator optical system to deliver spectral measurement across a wavelength range of 195nm to 1020nm — covering the full UV and visible spectrum required for most laboratory analytical work. Designed for medical and pharmaceutical testing, industrial environmental monitoring, commodity and food inspection, agricultural chemistry, water and wastewater analysis, petrochemical quality control, metallurgy, geology, machine manufacturing, and teaching laboratories in colleges and universities, the LI-285 is one of the most versatile single beam UV-VIS spectrophotometers in the Lasany product range. The instrument operates in three measurement modes — transmittance (T), absorbance (A), and concentration (C) — with a photometric accuracy of ±0.5%T and wavelength accuracy of ±2nm, supported by automatic zero setting and a clear 4-mode LCD display. Supplied as a complete out-of-box solution, the LI-285 includes software, RS-232 cable, a 4-cell glass cuvette accessory kit, 2 quartz cells, power cable, and full operating and software manuals — ensuring laboratories can begin spectrophotometric analysis immediately upon installation without additional procurement.

Why choose the LI-285?
- Software included as standard — no hidden costs — unlike many competing single beam spectrophotometers that sell data management software as a separate add-on, the LI-285 ships with full software and RS-232 cable included in the standard configuration, giving laboratories immediate PC connectivity and data capture capability without additional procurement or budget approval.
- Exceptionally broad application versatility — covering applications from pharmaceutical quality control to geology, petrochemical analysis to food and beverage testing, the LI-285’s wide wavelength range and three measurement modes make it suitable for multi-departmental laboratories and teaching institutions that need one instrument to serve diverse analytical curricula and research needs.
- CT grating monochromator delivers stable, accurate dispersion — the concave grating optical design provides reliable wavelength selection and dispersion stability across the full 195–1020nm range, supporting the ±2nm wavelength accuracy and 0.004 A/h stability that quantitative spectrophotometric analysis requires.
- Complete out-of-box solution reduces setup time — with glass and quartz cells, cables, software, and full documentation included, laboratories can install and begin operating the LI-285 the same day it arrives — without sourcing additional cuvettes, cables, or software licenses separately.
- ISO 9001:2015 certified Indian manufacturer — manufactured by Lasany International in Panchkula with CE certification, the LI-285 delivers internationally benchmarked analytical performance backed by Lasany’s established after-sales support network across India and export markets globally.
