Halo RB 10: UV / Visible Ratio Beam Spectrophotometer
The Halo RB-10 is a ratio beam spectrophotometer with an extensive array of built in functions for versatility and suitability to many analytical and biological applications. The ratio beam optics impart greater accuracy and reproducibility than the conventional, single beam optics.
190-1100 nm, 4 nm bandwidth. Complete with manual 4 cell changer.
Halo DB 20/ DB 20s: UV / Visible Double Beam Spectrophotometer
The Halo DB-20 is a high performance double beam spectrophotometer suitable for many analytical applications where a higher
level of accuracy is required.
Genuine Double Beam Optics
True double beam optics ensure concurrent measurement of the sample and reference for improved stability, accuracy and reproducibility. The light beam is split in two using a half mirror so that one beam passes through the sample side whilst the other passes through the reference side. Both beams are then measured on individual detectors. The reference side beam also acts to stabilize photometric values in a similar manner to the ratio beam principle.
DB-20: 190-1100 nm, 1.5 nm bandwith. Stray light: ≤0.05% (220nm Nal, 340nm NaNO2). Complete with 2-fold standard cell holder.
DB-20S: 190-1100 nm, 1.0 nm bandwith. ≤0.10% (220nm Nal, 340nm NaNO2). Complete with 2-fold standard cell holder.
Halo DB 30: UV / Visible Double Beam Spectrophotometer
The next generation Halo DB-30 double beam spectrophotometer boasts superlative performance characteristics for applications demanding the utmost sensitivity by combining higher signal to noise ratios with minimal stray light.
