Q6: How do you operate and execute an absorbance measurement on the SP-V1100 step-by-step?

• Warm-Up: Power on the spectrophotometer and allow it to preheat for at least 30 minutes to ensure baseline stability.

• Wavelength Selection: Use the keypad and LCD screen to automatically set your target analytical wavelength within the 325 to 1000 nm range.

• Blank Calibration: Insert a reference blank cuvette into the 4-position sample holder compartment and perform a baseline auto-zero calibration.

• Sample Testing: Place your sample cuvette into the optical path, close the compartment lid, and record absorbance, transmittance, or concentration values on the backlit LCD screen.

• Data Saving: Save test results directly into internal RAM storage (supporting up to 200 datasets and standard curves) or export data via the USB port.
