EI 1305 Microprocessor Visible Spectrophotometer | RS232, 340-960 nm
Product Description:
Overview:
The Model 1305 Microprocessor Visible Spectrophotometer is the most economical, reliable, rugged, and accurate instrument designed for spectrophotometric analysis of any concentration. Operating across the visible spectrum, this instrument is a highly stable and dependable tool suitable for applications in chemical, pharmaceutical, agricultural, biotechnological laboratories, hospitals, and educational institutions. It utilizes advanced microprocessor technology and engineering techniques to provide enhanced accuracy and reproducibility.
Core Functionality and Operation:
This single-beam visible spectrophotometer functions across a broad wavelength range of 340 nm to 960 nm. The system output is clearly displayed on a 16 x 2 line alphanumeric backlit LCD screen. Results are available directly in terms of:
• Percentage Transmission (%T)
• Absorbance (Abs.)
• Concentration (Conc.)
• KFactor
Operation is simplified via soft touch membrane keys, and the instrument offers essential practical features for modern laboratory environments.
Advanced Connectivity and Data Management:
This specific Model 1305 includes the capability for RS-232C Computer Interface (optional feature listed as required for this product configuration), facilitating data connectivity and transfer to a PC for comprehensive data handling and analysis via external software such as the designated EI-DVI brand software. Furthermore, the spectrophotometer features internal storage capacity for 100 samples. For hardcopy documentation, provision has been made for a printer attachment facility using a dot matrix printer via a Centronics interface.
Optical and Physical Design:
The instrument employs a robust optical system designed for high stability. The detection is handled by a Silicon Photodiode, illuminated by a powerful 6V, 10W, Tungsten Halogen Lamp. Wavelength separation is achieved using a 600 line/mm Diffraction grating. The instrument is designed with a sample holder accommodating 10mm Glass Square Cuvettes.
