UV Vis Spectrophotometer FAQ

Q1: What is the main advantage of a 2 nm narrow spectral bandwidth on the BRT-1800UV?

A: A 2 nm spectral bandwidth provides significantly higher optical resolution than standard 4 nm instruments. This allows for sharper peak resolution, cleaner separation of overlapping absorption bands, and superior accuracy during quantitative biological and pharmaceutical assays.

Q2: Can the BRT-1800UV perform DNA and protein purity testing without a PC?

A: While basic photometric and quantitative tests can be run standalone using the 128×64 LCD screen, connecting the BRT-1800UV to a PC via USB with the included software enables automated DNA/protein ratio calculations (260/280 nm), kinetics, and full spectral scanning.

Q3: How does the auto-calibration feature benefit daily testing?

A: The instrument automatically calibrates wavelength positions and saves dark current zeroing data during startup, eliminating time-consuming manual calibration before routine testing routines.
