The Labtron LUS-B33 UV-Vis Spectrophotometer covers a broad wavelength range from 190 to 1100 nm, making it suitable for a wide variety of samples, including UV and visible light applications. This range allows researchers to analyze both organic and inorganic compounds. The instrument also offers high wavelength accuracy of ±0.3 nm and repeatability up to 0.1 nm, which ensures precise and consistent results in every test. Accurate wavelength control is crucial in scientific experiments, especially in drug development, DNA/protein testing, and chemical analysis.
The Labtron Double Beam UV-Vis Spectrophotometer LUS-B33 features a double beam optical system with a 1200 lines/mm grating, which allows for better stability and accuracy. In a double beam system, the light is split into two paths—one for the sample and one for the reference which reduces the effect of lamp fluctuations and provides more reliable results. This design is especially useful for long-term measurements and kinetic studies, where stability over time is important.
The Labtron LUS-B33 supports a wide range of functions including photometric tests, quantitative analysis, kinetic studies, spectrum scanning, DNA/protein analysis, and multi-wavelength testing. This makes it ideal for use in pharmaceutical labs, environmental monitoring, clinical diagnostics, and toxicology. Whether you're checking concentration changes over time or analyzing the spectrum of a compound, this spectrophotometer can handle it all with precision.
The Labtron LUS-B33 supports GLP/GMP compliance, making it suitable for regulated laboratories. It includes useful features like user management, audit tracking, and log inquiry. These functions ensure that all operations are traceable and secure. Additionally, the system offers cloud connectivity, Bluetooth, WiFi, and even email/SMS options for real-time data sharing. This allows for seamless reporting and makes it easy to review or transfer data between team members and departments.
The Labtron Double Beam UV-Vis Spectrophotometer LUS-B33 is designed for ease of use. It comes with an 11-inch touch screen display, making navigation and data entry very simple. It also has Bluetooth support for wireless connectivity and real-time data sharing. The scanning speed can go up to 6000 nm/min, allowing fast and efficient measurements. All these features, along with its reliable stability and low noise, help researchers work faster and more accurately in busy laboratory settings.
