Product Overview
The Labtronics LT-29 UV/VIS Spectrophotometer is a precision-driven analytical device engineered for reliable and accurate absorbance and transmittance measurements across ultraviolet (UV) and visible light (VIS) spectrums. Designed for advanced performance with an easy-to-use layout, it is ideal for pharmaceutical, environmental, chemical, food, and academic laboratories.
Microprocessor-Controlled Accuracy
At the heart of the LT-29 lies an intelligent microprocessor unit that controls wavelength selection, data acquisition, and calibration. This automation minimizes manual handling errors, streamlines test cycles, and ensures repeatable, high-precision results—especially valuable in high-throughput environments and regulated industries.
Broad Spectral Coverage
With a wavelength range of 190 to 1100 nm, the LT-29 can handle both UV and visible light analysis with ease. Its dual-lamp system (deuterium for UV and tungsten-halogen for visible) delivers stable and intense illumination, crucial for detecting low concentrations or subtle spectral variations in samples.
Enhanced Measurement Performance
Although based on a single beam optical system, the LT-29 includes auto baseline correction to address background interference and solvent variability. It maintains photometric accuracy and sensitivity, supporting precise quantification of nucleic acids, proteins, pigments, and contaminants.
Designed for Real Lab Environments
Built with practical Safty lab needs in mind, the LT-29 is compact yet durable, featuring dust-resistant construction and anti-vibration support. Its digital interface displays absorbance, transmittance, and wavelength data clearly, ensuring user-friendly operation even for novice users.
