Description

Digital Photoelectric Colorimeter (Labtech) This is a light-sensitive instrument used to measure the absorbance and transmittance of specific wavelengths of light through a colored chemical solution to determine its concentration. Key Features and Capabilities Digital LED Display: A bright digital readout window on the lower left clearly displays optical density (absorbance) or transmittance values, eliminating the manual tracking errors common with older analog pointer needles. Manual Filter Selection Wheel: An internal wheel houses a standard set of optical glass filters, typically covering a wavelength range from roughly 400 nm to 700 nm. The knob on the right side lets users rotate and select the appropriate filter color to match the complementary absorption spectrum of the sample. Integrated Step-by-Step Instruction Guide: Printed directly on the front panel faceplate for easy operation, outlining the standard workflow: selecting the filter, blanking the instrument using a reference test tube, calibrating the density to zero, and testing the colored solution. Compact, Lightweight Footprint: A specialized molded plastic chassis fits easily on busy school lab benches or clinical workstations, while protecting the internal photodiode sensor from external ambient light leaks. Core Applications: Common in school chemistry practicals, clinical laboratories, and biochemical analysis for measuring hemoglobin levels, tracking enzyme reactions, and performing colorimetric chemical assays.
