11-inch Touch Screen with direct access to photometric measurement, quantitative analysis, wavelength scanning, and kinetics.
Dedicated modules for nucleic acid and protein testing to streamline workflows.
Dual-beam system for synchronous sample/reference detection, compensating for light source fluctuations, temperature drift, and ambient interference.
High-speed scanning: up to 30,000 nm/min with 0.02 nm interval.
Wide UV-Vis range: 190–1100 nm using imported deuterium & tungsten lamps with automatic switching.
Flexible slit adjustment: narrow slit for resolution, wide slit for sensitivity.
Data management: barcode scanner, permission management, e-signature, audit trail, LIMS connection.
Connectivity: cloud, USB-B, email, SMS, Bluetooth, Wi-Fi; optional printing.
Accessories available: auto sample holder, film holder, integrating sphere, peltier/sipper system, etc.
