The Macylab M-2900 is a highly accurate double-beam UV-Vis spectrophotometer operating across the 190nm to 1100nm wavelength range. Engineered for demanding analytical requirements, it allows operators to choose from six adjustable spectral bandwidths (0.1, 0.2, 0.5, 1.0, 2.0, and 4.0 nm) to optimize optical resolution based on the sample type.
Equipped with a 10-inch touch LCD screen and an integrated operating system, the instrument supports complex photometric analyses directly on the device. It utilizes an imported deuterium and tungsten halogen lamp combination alongside a silicon photodiode detector, making it a reliable platform for biological research, pharmaceuticals, and environmental protection.
Key Features
Double Beam Optical System: Splits the light path to simultaneously measure the sample and reference, significantly improving baseline stability (0.0003A/h @500nm) and minimizing background noise for long-term measurements.
Adjustable Spectral Bandwidth: Features six selectable bandwidth options (0.1, 0.2, 0.5, 1.0, 2.0, and 4.0 nm). This accommodates strict resolution requirements for various pharmacopeia standards and specific chemical analyses.
10-Inch Touch LCD Screen: Allows users to configure testing parameters, establish quantitative standard curves, and view analytical graphs directly on the large display without needing a connected computer.
Comprehensive Software Functions: The onboard software supports standard quantitative measurement, kinetics, multi-wavelength testing, full-band or segmented wavelength scanning, and specific DNA/protein purity analysis.
Flexible Data Management: Retains measurement parameters and test data after power down. It features a USB interface for outputting measurement data to a printer, and supports optional PC control for extended data manipulation.
