Adjustments to the concentration of water and salts within the urine takes place mainly in the distal parts of the tubules and in the collecting tubules, by altering the permeability of the membranes of cells lining the nephron walls. These changes are brought upon to two hormones, ADH and aldosterone.
Use for Colorimetric and Turbidimetric Determinations. These photometric colorimeters use specific light filters to give readings on a unique KlettTM scale. The readings are directly proportional to the concentration or optical density of a solution, in accordance with Beers Law.
The BTS256-E Light-Color-Spectral Meter measures illuminance in lux as well as color quantities and spectral distribution. The BTS256-LED Tester can be used four different ways: stand-alone, mounted onto an integrating sphere or goniometer bench or with a diffuser window attachment.
