Manufactured by\u00a0<strong>Lasany International<\/strong>\u00a0under 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 \u2014 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 \u2014 transmittance (T), absorbance (A), and concentration (C) \u2014 with a photometric accuracy of \u00b10.5%T and wavelength accuracy of \u00b12nm, 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 \u2014 ensuring laboratories can begin spectrophotometric analysis immediately upon installation without additional procurement.<\/p>\n<\/div>\n<div class=\"section\">\n<h3 class=\"section-title\"><strong>Key features<\/strong><\/h3>\n<div class=\"features-grid\">\n<ul>\n<li class=\"feat-card star\"><i class=\"ti ti-cpu\"><\/i><strong>Microprocessor control <\/strong>Microprocessor-based control system with included software for complete spectral data management.<\/li>\n<li class=\"feat-card star\"><i class=\"ti ti-arrows-left-right\"><\/i><strong>195\u20131020nm wavelength range <\/strong>Wide UV-visible spectral coverage suitable for the broadest range of analytical applications.<\/li>\n<li class=\"feat-card\"><i class=\"ti ti-grain\"><\/i><strong>CT grating monochromator <\/strong>Concave\/Czerny-Turner grating optical system delivers precise, stable wavelength dispersion.<\/li>\n<li class=\"feat-card\"><i class=\"ti ti-list-numbers\"><\/i><strong>3 measurement modes <\/strong>Transmittance (T), Absorbance (A), and Concentration (C) \u2014 full analytical flexibility in one instrument.<\/li>\n<li class=\"feat-card\"><i class=\"ti ti-usb\"><\/i><strong>RS-232 + software included <\/strong>Direct PC connectivity standard \u2014 no separate software purchase required for data management.<\/li>\n<li class=\"feat-card\"><i class=\"ti ti-refresh\"><\/i><strong>Automatic zero setting <\/strong>Automated zero calibration simplifies operation and reduces baseline-related measurement errors.<\/li>\n<li class=\"feat-card\"><i class=\"ti ti-device-desktop\"><\/i><strong>4-mode LCD display <\/strong>Clear digital display across 4 display modes for direct, intuitive result reading.<\/li>\n<li class=\"feat-card\"><i class=\"ti ti-package\"><\/i><strong>Complete accessory kit <\/strong>Includes glass and quartz cells, cables, software CD, and full manuals \u2014 ready to use out of box.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<div class=\"section\">\n<h3 class=\"section-title\"><strong>Technical specifications<\/strong><\/h3>\n<div>\n<table class=\"specs-table\">\n<tbody>\n<tr>\n<td>Model<\/td>\n<td>LI-285<\/td>\n<\/tr>\n<tr>\n<td>Optical system<\/td>\n<td>Single beam \u00b7 CT grating monochromator<\/td>\n<\/tr>\n<tr class=\"hl\">\n<td>Wavelength range<\/td>\n<td>195 \u2013 1020 nm<\/td>\n<\/tr>\n<tr>\n<td>Spectral bandwidth<\/td>\n<td>2 nm<\/td>\n<\/tr>\n<tr>\n<td>Wavelength accuracy<\/td>\n<td>\u00b1 2 nm<\/td>\n<\/tr>\n<tr>\n<td>Wavelength repeatability<\/td>\n<td>\u2264 1 nm<\/td>\n<\/tr>\n<tr class=\"hl\">\n<td>Photometric accuracy<\/td>\n<td>\u00b1 0.5%T<\/td>\n<\/tr>\n<tr>\n<td>Photometric repeatability<\/td>\n<td>\u00b1 0.3%T<\/td>\n<\/tr>\n<tr>\n<td>Photometric range<\/td>\n<td>-0.3 \u2013 3A \/ 0\u2013200%T<\/td>\n<\/tr>\n<tr>\n<td>Stray light<\/td>\n<td>\u2264 0.3%T @220nm<\/td>\n<\/tr>\n<tr>\n<td>Stability<\/td>\n<td>0.004 A\/h @500nm<\/td>\n<\/tr>\n<tr>\n<td>Display area<\/td>\n<td>4 LCD display modes<\/td>\n<\/tr>\n<tr>\n<td>Work pattern<\/td>\n<td>T, A, C (Transmittance, Absorbance, Concentration)<\/td>\n<\/tr>\n<tr>\n<td>Zero setting<\/td>\n<td>Automatic<\/td>\n<\/tr>\n<tr>\n<td>Data output<\/td>\n<td>RS-232 with software (included)<\/td>\n<\/tr>\n<tr>\n<td>Weight<\/td>\n<td>12 kg<\/td>\n<\/tr>\n<tr>\n<td>Certification<\/td>\n<td>ISO 9001:2015 \u00b7 CE<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<div>\n<div><strong>Standard configuration<\/strong><\/div>\n<div class=\"acc-row\"><span class=\"acc-chip\">Main set (1), <\/span><span class=\"acc-chip\">Software (1), <\/span><span class=\"acc-chip\">RS-232 cable (1), <\/span><span class=\"acc-chip\">4-glass cell accessory kit (1), <\/span><span class=\"acc-chip\">2\u00d7 Quartz cells, <\/span><span class=\"acc-chip\">Power cable (1), <\/span><span class=\"acc-chip\">Operating manual (1), <\/span><span class=\"acc-chip\">Software manual + CD (1)<\/span><\/div>\n<div><\/div>\n<\/div>\n<\/div>\n<div class=\"section\">\n<h3 class=\"section-title\"><strong>Applications<\/strong><\/h3>\n<div class=\"apps-row\">\n<ul>\n<li class=\"app-pill\"><i class=\"ti ti-pill\"><\/i>Medical\/pharmaceutical<\/li>\n<li class=\"app-pill\"><i class=\"ti ti-leaf\"><\/i>Environmental monitoring<\/li>\n<li class=\"app-pill\"><i class=\"ti ti-package\"><\/i>Commodity inspection<\/li>\n<li class=\"app-pill\"><i class=\"ti ti-apple\"><\/i>Food inspection<\/li>\n<li class=\"app-pill\"><i class=\"ti ti-plant-2\"><\/i>Agricultural chemistry<\/li>\n<li class=\"app-pill\"><i class=\"ti ti-school\"><\/i>Colleges &amp;
