EmailThe A2000 Fully Automatic UV-Visible Spectrophotometer integrates technologies such as sequential flow injection and automated analysis. Its autosampler is specifically designed for UV-Vis spectrophotometry and is ideal for continuous testing of large sample volumes. Samples can be placed in standard test tubes, and the instrument automatically performs injection, measurement, cuvette cleaning, and other complex tasks—making analysis simpler, faster, and more accurate. It reduces operational errors, saves time and reagents, and is more environmentally friendly.
Features
Automated Flow Injection & Online Analysis: Reduces manual errors and time costs by automating sample injection, photometric measurement, and data analysis.
Direct-Insertion Sampling Design: Simply insert the sampling tube into a test tube to initiate the full process—sampling, measurement, cuvette drainage, and cleaning—greatly simplifying lab workflows.
Dual-Beam Optical System: Enhances resolution, minimizes stray light interference, and ensures high stability and reliability for precise results.
Socket-Type Tungsten & Deuterium Lamps: Eliminates the need for optical realignment during lamp replacement, simplifying maintenance.
User-Friendly Design: Offers flexible and convenient operation and maintenance for lab personnel.
Suspended Optical System: Isolates the optics from baseplate deformation and external vibrations, improving measurement precision and long-term reliability.
Autosampler Capacity: Supports up to 60 sample positions, boosting throughput and efficiency.
