FAQs of MICROPROCESSOR SPECTROPHOTOMETER 2305:

Q: How does the Microprocessor Spectrophotometer 2305 ensure measurement accuracy?

A: The Model 2305 incorporates a highly stable optical system with a silicon photodiode detector, wavelength accuracy of 2 nm, and photometric accuracy of 0.5%% T. Automatic lamp switching between tungsten and deuterium sources further minimizes manual errors and maintains consistent accuracy across its measurement range.

Q: What is the process for using the 4-position cuvette holder included with the 2305?

A: Users can insert up to four cuvettes (two glass, two quartz included) into the holder. The device allows for swift selection and measurement of each cuvette, streamlining workflows that require parallel or comparative analysis of multiple samples.

Q: When is it beneficial to utilize both glass and quartz cuvettes with this spectrophotometer?

A: Quartz cuvettes are recommended for measurements in the UV range (below 350 nm), while glass cuvettes suffice for visible spectrum analysis. The inclusion of both types allows users to perform a broader range of assays without additional accessories.

Q: Where can data outputs from the 2305 be exported for analysis or record-keeping?

A: Data obtained from the spectrophotometer can be exported through its RS232 interface, enabling easy integration with laboratory computers or external storage devices for efficient documentation and further data analysis.

Q: What are the main benefits of using the Microprocessor Spectrophotometer 2305 in a laboratory setting?

A: Benefits include high measurement accuracy, broad wavelength range, user-friendly semi-automatic operation, durable construction, and compatibility with both glass and quartz cuvettes. These features collectively support reliable, repeatable results for varied laboratory applications.

Q: How does automatic light source switching improve laboratory workflow with the 2305?

A: Automatic switching between tungsten and deuterium lamps optimizes light frequency for sample analysis, eliminating manual adjustments. This enhances efficiency and reduces potential errors, particularly during extensive or sequential spectroscopic measurements.
