FAQs of Single Beam Spectrophotometer:
Q: How does the SB-11 Single Beam Spectrophotometer achieve high measurement accuracy?
A: The SB-11 uses a tungsten halogen lamp and a precisely tuned monochromator, alongside a silicon photodiode detector. With wavelength accuracy of 2 nm and photometric accuracy of 0.5% T, the system consistently delivers reliable and reproducible results for quantitative and qualitative analysis.
Q: What is the process for calibrating the spectrophotometer before use?
A: Calibration is straightforward due to the auto zero and blank features. Prior to measurements, users simply insert a blank sample and follow on-screen instructions. The spectrophotometer automatically adjusts for background absorbance, ensuring accurate subsequent readings.
Q: When should the tungsten halogen lamp be replaced?
A: The lamp has a typical life of around 1000 hours under standard laboratory conditions. It should be replaced once its intensity diminishes or after reaching its rated operating hours to maintain consistent measurement quality.
Q: Where can the spectrophotometer be used effectively?
A: Designed for laboratory environments, the SB-11 is ideal for educational institutions, pharmaceutical labs, chemical analysis setups, and research facilities, operating in ambient conditions with humidity up to 85% RH (non-condensing).
Q: What types of samples can be measured with this device?
A: The SB-11 is suitable for liquid samples that can be held in 10 mm square cuvettes. Its measurement range spans 340 to 1000 nm, making it effective for various solutions in chemistry, biology, and pharmaceutical applications.
Q: How is data managed or exported from the SB-11 spectrophotometer?
A: By default, results are displayed clearly on the LCD digital display. For enhanced data management, an optional RS232 port is available for connection to external devices, though the standard model does not feature direct data output capabilities.
Q: What are the benefits of choosing this spectrophotometer for laboratory work?
A: The SB-11 offers rapid response time, stable photometric readings, and easy operation, ensuring minimal user error. Its robust design reduces maintenance, and the user-friendly features support efficient workflows, making it a practical and accurate choice for regular laboratory analysis.
