This makes it accessible for users with varying technical backgrounds and enhances lab productivity.
Our Ultra Micro UV-Vis Spectrophotometer LMVS-B12 is designed for low maintenance with its robust stainless steel and quartz optical components. It performs an automatic self-test at startup to check for impurities or system errors. Regular calibration can be conducted using standard reference materials provided by the manufacturer or third-party calibration kits. Firmware updates and software upgrades are easily performed via USB. Routine cleaning of the sample platform with appropriate solvents is recommended to ensure consistent performance and prevent contamination. Its durable build minimizes downtime, making it ideal for high-throughput labs. The intuitive software also provides alerts for maintenance and calibration schedules.
The Ultra Micro UV-Vis Spectrophotometer LMVS-B12 is designed for a wide range of applications, including nucleic acid quantification, protein analysis, microbial culture monitoring, and fluorescence-based assays. Its ultra-low sample volume capability makes it ideal for precious or limited samples. Researchers use it for DNA/RNA purity checks, protein concentration determination, and kinetic studies. The fluorescence detection module also allows quantification of trace nucleic acids in samples that are difficult to measure by traditional photometers. Additionally, it supports OD600 measurements for microbial growth monitoring, making it versatile for clinical, pharmaceutical, and biotechnology laboratories.
Our Ultra Micro UV-Vis Spectrophotometer LMVS-B12 requires only 0.5 to 2 µL of sample, which it analyzes using a liquid column formed between two optical fibers. This ultra-micro volume detection minimizes sample waste and is perfect for samples that are difficult or expensive to obtain. The system ensures high sensitivity and accuracy even at such low volumes. This makes it highly suitable for molecular biology and biochemistry applications where sample conservation is critical. The precise liquid handling and stable light source improve measurement reliability despite the small sample size.
Yes, the Ultra Micro UV-Vis Spectrophotometer LMVS-B12 supports kinetic measurements by tracking absorbance changes over time at user-defined wavelengths. It can run up to 100 kinetic programs, providing detailed real-time data on reaction dynamics such as enzyme activities or microbial growth. This feature is valuable in biochemical research, drug development, and cell biology. The kinetic mode also includes graphical displays for easy interpretation of results, allowing scientists to observe trends without requiring separate software.
