Visible Spectrophotometer - Single Beam Touch Screen Photometer - 325-1100 nm - 2 nm Bandwidth

The Master Science Visible Spectrophotometer is a single-beam instrument built around an ARM processor core for routine quantitative analysis. It covers 325 to 1100 nm with a 2 nm spectral bandwidth and sets the wavelength automatically.

A 7-inch colour touch screen shows results clearly and gives access to wavelength scanning, kinetic time scanning, linear regression and direct concentration read-out. The sample compartment takes cuvettes from 5 to 100 mm path length.

Common Problems and How This Spectrophotometer Helps

How the Master Science Visible Spectrophotometer simplifies routine photometry:

• Manual wavelength dialling errors: automatic wavelength drive.
