Double Beam UV-Vis Spectrophotometer - 190-1100 nm Range - 0.5-6 nm Variable Bandwidth

The Master Science Double Beam UV-Vis Spectrophotometer measures absorbance and transmittance from 190 to 1100 nm with a Czerny-Turner monochromator and a true double-beam optical path. Real-time reference correction cancels lamp and electronic drift, so baselines stay flat through long kinetic and scanning runs.

A spectral bandwidth adjustable from 0.5 to 6 nm in 0.1 nm steps lets the user balance resolution and signal for each method, from narrow pharmacopoeia bands to routine concentration checks.

Key Benefits

• Flexible resolution: choose any bandwidth between 0.5 and 6 nm to match the sharpness of your absorption bands.
• Accurate readings at high absorbance: stray light below 0.03 % keeps results linear for dense or strongly absorbing samples.
• Stable baselines: the Master Science Double Beam UV-Vis Spectrophotometer compares sample and reference beams continuously to cancel drift.
• Lower running cost: the long-life deuterium lamp is rated for more than 2000 hours of operation.
• Fast lamp changes: pre-aligned lamps are replaced without removing the housing or realigning optics.

Laboratories adding chromatographic separation to their spectroscopy work can also look at the Master Science quaternary HPLC system.

Common Laboratory Problems and How This Spectrophotometer Helps

Everyday spectroscopy issues and how the Master Science Double Beam UV-Vis Spectrophotometer handles them:

• Baseline drift during long runs: double-beam correction compensates for lamp and detector changes.
• Non-linear results at high absorbance: very low stray light extends the usable range.
• Frequent lamp replacement: long-life lamps reduce downtime and spare part cost.
• Wavelength errors over time: automatic wavelength verification keeps accuracy within ±0.3 nm.
• Paper records for regulated labs: optional audit-trail software keeps electronic traceability.
