AT LAST, THE WORLD'S FIRST. The first system for completely automatic titrimetric, colorimetric and/or selective ion analyses using your chemistries and your procedures. And our microcomputer based DigiChem® 4000 series Programmable Chemical Analyzer. Introducing a remarkable advance in wet chemical analysis simplicity, versatility and a u t o m a t i o n : The DigiChem 4000 series. This is the only instrument available that significantly advances titrimetric, colorimetric and selective ion analysis technology and allows you to automatically c o m b i n e one, two, three or more of these methods of chemical analysis. All using your chemistries and procedures. (Or EPA, ASTM, and Standard Methods.) All automatically. All at the touch of a b u t t o n . And at a surprisingly attractive cost.
Make your simple or complex analyses routine. The DigiChem has 4 basic models. All operate unattended so you and your technicians can put your minds, and hands to more productive tasks. You simply select the correct (preprogrammed or userprogrammed) analytical procedures. And the DigiChem quickly executes them automatically on single or multiple samples (up to 200!) using one or several procedures. Without further operator attention. The 4200 Titrator automatically samples, prepares the sample and analyzes it by one or several titrimetric procedures, then prints out the results in the concentration units you use daily.
The 4400 Selective Ion Analyzer advances these types of ion selective electrode measurements with automatic sample and multiple reagent additions; and completely automatic analysis using standard addition or Gran's Plot techniques. The 4600 Colorimetric Analysis System eliminates the need for multiple colorimeter instruments w i t h its programmable wavelength selection. It also eliminates peristaltic pumps, a perpetual maintenance p r o b l e m , and a factor in sample-to-sample cross contamination and analysis inaccuracies. The 4800 does all three types of analysis methods. What's more, you can order the model you need now and maximize capabilities later at a minimal cost.
