Model: UVS-2800

NSX: Labomed - Mỹ

Spectro UV-Vis Dual Beam is a precise scanning Spectrophotometer with a new design of 8 microprocessor automatic 2 row cell holder that moves noiseless with a special membrane. This has a single detector and a very accurate system.

Spectro UV-Vis Dual Beam can perform protein, nucleic acid, DNA/RNA micro and macro measurements.

Baseline Stability: The monitoring ratio system enhances baseline stability.

Excellent Resolution: The big-caliber light path enhances the instrument’s energy, reduces its noise and raises its resolution performance.
