BioPhotometer plus: Cuvette Photometer for Laboratory Analysis
The Eppendorf BioPhotometer plus is an essential instrument for laboratories specializing in molecular biology, biochemistry, and cell biology. It is designed to perform photometric measurements with high precision, particularly for quantifying nucleic acids, proteins, and labeled biomolecules. With its integrated and customizable methods, it offers valuable flexibility in sample evaluation.
This device uses a xenon light source and a concave holographic grating monochromator to ensure stability and reproducibility of measurements. It operates on the principle of single-beam photometry with a reference beam, allowing for correction of potential light variations.
Users can quickly access preconfigured programs to measure the concentration of various analytes, including DNA, RNA, proteins, and bacterial density (OD600). It is also possible to program custom methods to meet specific needs. The device supports nine fixed wavelengths ranging from 230 nm to 650 nm, suitable for many laboratory applications.
The ergonomics of the BioPhotometer plus are designed for intuitive use. Its backlit graphic display makes reading results and navigating menus easy. Controls are accessible via a 19-key membrane keypad, simplifying the execution of analyses. The device allows the storage of 100 measurements with detailed data, including absorbance values, ratios, and dilutions used.
The BioPhotometer plus works with standard glass or plastic cuvettes, as well as Eppendorf's UVette cuvettes, specifically designed for UV measurement of nucleic acids and proteins. It features an RS-232 connection port for exporting results to a printer or computer.
Its compact and lightweight design (3 kg) makes it easy to integrate into any laboratory environment. Its robustness and precision make it a reliable tool for reproducible daily analyses.
