FAQs of Visible Spectrophotometer:
Q: How is sample analysis performed using this visible spectrophotometer?
A: Simply insert the sample into one of the four cuvette slots (compatible with 10 mm path length cuvettes), select the desired wavelength (within 3201000 nm), and follow the guided instructions on the digital display. Automatic zero and blank calibration streamline preparation, ensuring accurate absorbance or transmittance readings.
Q: What are the primary benefits of using this spectrophotometer in laboratory or educational research?
A: This spectrophotometer offers high measurement accuracy (2 nm wavelength accuracy, 0.5% T photometric accuracy), robust construction for sustained use, automatic calibration, and internal memory to store up to 200 test results. It simplifies both quantitative and qualitative sample analysis for researchers, clinicians, and educators.
Q: When should the tungsten halogen lamp be replaced, and how long does it typically last?
A: The tungsten halogen lamp typically lasts up to 2000 hours under regular use. Lamp replacement should be considered when the instrument fails to reach expected intensity levels or after reaching its rated operational life to maintain reliable measurements.
Q: Where is this spectrophotometer best utilized?
A: This instrument is ideally suited for dust-free and well-ventilated laboratory environments, including clinical labs, research institutes, and educational institutions. Its robust design and automation features make it versatile for chemical, biological, and teaching applications.
Q: What is the process for calibrating the spectrophotometer before use?
A: The device features automatic zero and blank calibration. Before measuring samples, simply follow the on-screen prompts to perform both calibrations, ensuring the baseline is set and any background absorbance is accounted for, resulting in accurate measurement data.
Q: How does the digital display help users operate and monitor results?
A: The LED/LCD digital display offers clear visualization of measurement parameters, results, and system status. It provides easy navigation through settings and allows users to recall up to 200 stored test results for review and reporting.
Q: What advantage does the instruments low stray light rate and high baseline flatness provide?
A: A stray light rate of 0.3% T and baseline flatness of 0.003 A greatly reduce measurement errors and enhance data consistency, making the spectrophotometer especially valuable for precision-driven applications in clinical diagnostics and research.
