Visible Spectrophotometer FAQ

1º trimestre: What is the main operational difference between the BRT-1150V and a UV-Vis spectrophotometer?

UM: The BRT-1150V operates specifically within the visible spectrum (325–1050nm) using a tungsten halogen light source, making it ideal and cost-effective for colorimetric assays using glass cuvettes, whereas UV-Vis units include a deuterium lamp to cover the ultraviolet range (190–325 nm).

2º trimestre: Can the BRT-1150V accommodate long-path cuvettes for low-concentration samples?

UM: Sim, the spacious sample chamber is fully compatible with cell holders designed for optical path lengths from 5 mm up to 100 milímetros, allowing sensitive detection of dilute solutions.

3º trimestre: How does connecting optional PC software expand the functionality of the BRT-1150V?

UM: Connecting the instrument via USB to optional PC analysis software unlocks advanced capabilities such as continuous full-spectrum scanning across 325–1050 nm, time-course kinetic monitoring, and multi-wavelength testing.
