Colorimeter for Reading Paper-Based Devices

Some investigators describe a point-of-care system, with a microfluidic paper device and a handheld optical colorimeter, for quantifying analyte concentrations in biological fluids. First came paper-based microfluidic devices. Then came the idea of using camera phones to relay data from paper-based assays. an inexpensive handheld colorimeter that generates quantitative data in a point-of-care analytical system. …

Some Problems in the Use and Maintenance of Colorimeter

Many teaching and research departments in medical colleges and universities ( such as chemistry, biochemistry, disease, pharmacology, etc.) use various types of colorimeter( colorimetric meters). Colorimeters are expensive and easy to damage, such as department students use, damage more frequently, so repair use has become an important problem. The general maintenance personnel does not understand …

Colorimeter for the Student Laboratory

Analytical instruments often seem as inconspicuous “black boxes”, with vital components well hidden from plain sight. Despite the understandable engineering requirements to shield components from the environment, usually little is given in the way to provide students with a sense of the instrument’s inner workings. One of the most common applications of colorimeters and the …
