Overview
The BS15 Benchtop Spectrophotometer is a compact, high-stability UV-Vis spectrophotometer engineered for routine quantitative and qualitative analysis in quality control laboratories, academic teaching environments, and small-scale R&D settings. Operating on the principle of single-beam absorbance measurement across the 190–1100 nm spectral range, the BS15 employs a holographic grating monochromator and a low-noise silicon photodiode detector to deliver consistent photometric accuracy and baseline stability. Its optical design minimizes stray light (< 0.05% at 220 nm), ensuring reliable compliance with ISO 9001-certified analytical workflows and supporting method validation per ICH Q2(R2) guidelines where applicable. The instrument features fixed slit geometry and pre-aligned optics, eliminating user calibration drift under standard ambient lab conditions (15–30 °C, < 70% RH, non-condensing).
Key Features
- Wavelength range: 190–1100 nm with 1.0 nm nominal bandwidth
- Photometric accuracy: ±0.002 A at 0.5 A (certified with NIST-traceable neutral density filters)
- Baseline flatness: ±0.001 A over full scan range (200–800 nm)
- Integrated cuvette holder accommodating 10 mm pathlength cells (standard), with optional 5 mm, 20 mm, or 50 mm holders available
- USB 2.0 interface for direct connection to Windows-based PCs; no external power adapter required (powered via USB bus)
- Embedded firmware with onboard memory for up to 100 stored methods and 500 spectra
- Robust aluminum alloy chassis with ESD-safe housing and IP20-rated enclosure
Sample Compatibility & Compliance
The BS15 supports liquid-phase analysis using standard quartz, glass, or plastic cuvettes. It is compatible with common solvents including water, methanol, ethanol, acetone, and dilute aqueous buffers—provided sample absorbance remains within the linear dynamic range (0.01–3.0 A). For regulatory environments, the system supports audit-ready operation when paired with compliant software: electronic records meet FDA 21 CFR Part 11 requirements for signature attribution, data integrity, and change control when used with validated third-party LIMS or ELN platforms. Instrument qualification documentation—including Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) templates—is provided to support GLP and GMP laboratory implementation.
Software & Data Management
The BS15 operates with dedicated PC-based acquisition software compatible with Windows 10/11 (64-bit). Software capabilities include kinetic scanning, multi-wavelength quantitation, spectrum subtraction, peak detection with wavelength/absorbance reporting, and export to CSV, TXT, or PDF formats. All spectral acquisitions are timestamped and embedded with instrument ID, lamp hours, and operator-defined metadata. Raw absorbance data retains full 12-bit resolution (4096 data points per scan), enabling post-acquisition smoothing, derivative analysis, or integration into chemometric workflows. Audit trail functionality logs all method modifications, data deletions, and user logins—configurable to align with internal SOPs and external inspection readiness protocols.
Applications
- Concentration determination of nucleic acids (A260/A280 ratio analysis) and proteins (Bradford, Lowry, BCA assays)
- Enzyme kinetics monitoring (e.g., NADH/NADPH oxidation at 340 nm)
- Pharmaceutical excipient purity verification per USP UV-Vis Spectrophotometry
- Water quality assessment (nitrate, phosphate, COD estimation via colorimetric reagents)
- Teaching laboratory experiments covering Beer-Lambert law validation, λmax identification, and molar absorptivity calculation
- Raw material identity testing in contract manufacturing organizations (CMOs) under ICH Q5 and Q7 frameworks
FAQ
Is the BS15 compliant with ISO/IEC 17025 requirements for accredited testing laboratories?
Yes—the instrument’s documented performance specifications, traceable calibration certificates, and defined uncertainty budgets enable integration into ISO/IEC 17025 quality management systems when operated per manufacturer-recommended maintenance intervals and environmental controls.
Can the BS15 be integrated into an existing LIMS environment?
Direct LIMS integration is supported via ASCII-based data export (CSV/TXT) and optional OPC UA-compliant middleware; custom API development services are available through authorized distribution partners.
What is the expected lamp lifetime and replacement procedure?
The deuterium and tungsten-halogen lamps are rated for 1,000 hours and 2,000 hours respectively; replacement requires no optical realignment and can be completed in under 5 minutes using standard Torx tools.
Does the BS15 support automatic wavelength calibration?
No—wavelength calibration is factory-performed using holmium oxide and didymium reference filters; periodic verification (recommended annually) is performed manually using the same certified standards.
Is service and technical support available outside the UK?
Yes—global technical support, preventive maintenance contracts, and certified field service engineers are coordinated through the manufacturer’s authorized distributor network across EMEA, APAC, and the Americas.
