Double Beam Microprocessor UV-VIS Spectrophotometer LI-2800 Ex with Peltier & Sipper System

Description

Product Overview

Redefine the limits of spectrophotometric analysis with the Double Beam Microprocessor UV-VIS Spectrophotometer LI-2800 Ex with Peltier & Sipper System—the most advanced temperature-controlled, automated sample-handling spectrophotometer in Lasany International’s flagship product lineup.

Designed for laboratories that demand more than standard UV-VIS measurements, the LI-2800 Ex combines a precision double beam optical architecture with two breakthrough technologies: an integrated Peltier temperature control system for thermally regulated sample analysis and an automated Sipper System that draws liquid samples directly into the cuvette—eliminating manual handling, reducing contamination risk, and dramatically increasing measurement throughput.

From pharmaceutical kinetic studies and enzyme reaction monitoring to high-volume environmental water testing and clinical sample analysis, the Double Beam Microprocessor UV-VIS Spectrophotometer LI-2800 Ex is the instrument of choice for modern analytical laboratories that cannot compromise on precision, efficiency, or regulatory compliance.

Key Features

• True Double Beam Optical Design—Splits the light source into simultaneous sample and reference beams, providing continuous baseline correction that eliminates errors from lamp drift, detector noise, and environmental fluctuations—delivering measurements of unmatched stability and reproducibility.
• Peltier Temperature Control System—Precisely regulates sample compartment temperature from 15°C to 65°C, making the LI-2800 Ex uniquely suited for temperature-sensitive experiments, including enzyme kinetics, protein denaturation studies, and thermodynamic reaction monitoring. No external water bath or cooling unit required.
• Integrated Sipper System — Automates liquid sample aspiration into the cuvette via a peristaltic pump with a speed range of 1 to 12 and a high sampling throughput of approximately 50 ml/min. Reduces analyst contact with samples, minimizes cross-contamination, and enables consistent, hands-free high-throughput analysis.
• 8-Cell Cuvette Holder—Accommodates up to 8 standard 10 mm cuvettes simultaneously, enabling multi-sample batch analysis without repeated manual cuvette changes—ideal for high-volume QC laboratories.
• Advanced Microprocessor Control — A high-speed ARM-based microprocessor with an intuitive keypad/display interface manages all instrument functions—from automated wavelength selection and data acquisition to complex analytical calculations—with minimal operator input.
• Full UV-VIS Spectral Coverage — Operates across 190 nm to 1100 nm using a dual deuterium (UV) and tungsten-halogen (visible) lamp system with seamless automatic crossover, ensuring complete spectral access in a single instrument.
• Multiple Analytical Modes — Supports six measurement modes out of the box: Basic Photometry, Quantitative Analysis, Kinetics, Multi-Wavelength, Wavelength Scan, and DNA/Protein Testing — making it one of the most versatile spectrophotometers in its class.
• Flexible Time-Course Analysis—Kinetic and time-range studies are configurable from 30 seconds to 10 minutes, with precise Peltier temperature maintenance throughout, enabling accurate real-world simulation of biochemical processes.
• GLP/GMP Compliance Ready — Features data logging, time/date stamping, instrument diagnostics, and user access management to meet the compliance requirements of NABL, ISO, GLP, and GMP-accredited laboratories.
• PC Connectivity & Software — USB and RS-232 interfaces enable seamless data transfer to computers and integration with LIMS. Compatible with Lasany’s dedicated analytical software for spectral scanning, kinetics data plotting, and comprehensive report generation.
