Testing Workflow & Target Applications

Standardized Testing Workflow:

1. Power on the BRT-5000UV; the system automatically initiates self-testing, wavelength calibration, and baseline balance adjustments.
2. Select the desired operating mode (Photometric, Quantitative, or Concentration) on the 4.3-inch color touch screen.
3. Place a reference blank cuvette into the sample compartment to zero the instrument (0A and 100%T balance).
4. Insert the sample cuvette into the optical path, measure absorbance or transmittance values, or fit standard sample concentration curves.
5. Save results into internal memory (up to 200 data sets) or export data directly to PC software via USB for advanced reporting.

Target Customer Applications:

• Environmental water quality analysis centers (COD, nitrate, phosphate, and heavy metal detection).
• Pharmaceutical quality control facilities and life science analytical laboratories.
• Chemical processing plants, petrochemical QA bays, and textile dye inspection stations.
• University chemistry departments and food & beverage safety testing labs.

UV-Vis Spectrophotometer FAQ

Q1: What pathlength cuvettes can be used with the BRT-5000UV?

A: The standard sample compartment is designed to accommodate cuvettes with optical pathlengths ranging from 5 mm up to 100 mm, allowing analysis of both low-concentration and high-turbidity samples.

Q2: Does the instrument require manual wavelength calibration upon startup?

A: No. The BRT-5000UV features automatic self-testing and wavelength calibration upon powering on, alongside automatic 0A and 100%T baseline calibration.

Q3: Why are quartz cuvettes required for ultraviolet (UV) measurements?

A: Standard glass cuvettes absorb ultraviolet light below 340 nm, interfering with sample readings. Quartz cuvettes are optically transparent across both UV (200–340 nm) and Visible (340–1000 nm) spectrums.
