GENESYS 20

HSX: Thermo Scientific - Mỹ

Thermo Scientific* GENESYS* 20 is a compact, low-cost, easy-to-use, Visible spectrophotometer designed for classrooms and routine laboratories.

A simple, 4-step measurement process and optional VISIONlite* software make the GENESYS 20 the most cost-effective, visible spectrophotometer available.

Multiple purpose capabilities allow you to measure a wide range of analytes.

Precise and Reliable

• Patented optical design provides a compact, space-saving, high-performance system
• Intuitive keyboard with integrated controls and graphic display
• Routine measurements require just a few keystrokes
• 3-step process accesses routine absorbance of transmittance data
• Provides information concerning instrument status, prompts for setup or change of parameters, and instrument diagnostic information
• User-selectable choice of five languages (English, French, German, Spanish, Italian)
• Bidirectional RS-232-C interface

Low Cost of Ownership

• Cleanable, chemical-resistant surfaces and rugged design withstands harsh laboratory environments
• Few moving parts; virtually maintenance-free operation

• Choose instrument with single- or six-position cell holder, with or without integral printer
