Microprocessor UV-VIS Spectrophotometer-2371

Microprocessor U-VIS Spectrophotometer is a solid state microcontroller based instrument designed for quick and accurate spectrophotometric analysis of any concentration. It operates at a wavelength range of 200 nm to 1000 nm. The instrument uses the latest microprocessor technology and advanced engineering techniques so as to give enhanced accuracy and reproducibility.

The instrument is equipped with 128 x 64 dots large graphical lcd the makes the result easy to read. The system has soft touch numeric keys for ease of operation

Provision has also been made for attachment of any dot matrix printer using centronics interface and PC connectivity through USB port.

Large Sample Compartment, can accommodate 5-100 mm path-length cuvettes with optional holders. The instrument is supplied with a 4 position 10 mm cell changer.

The âBasicâ PC software for quantitative / kinetic mode is supplied with the instrument. The âProfessionalâ PC software is optional for extending the functionality to wavelength scanning and DNA/Protein analysis (at extra cost).
