Bruker Tensor 27 FTIR Spectrometer (Refurbished)

Overview

The Bruker Tensor 27 is a high-performance, laboratory-grade Fourier Transform Infrared (FTIR) spectrometer engineered for precision molecular identification and quantitative analysis across research, quality control, and regulatory environments. Based on Michelson interferometry with a permanently aligned optical path and KBr-beam splitter configuration, the system delivers high spectral resolution (typically ≤ 0.4 cm⁻¹), excellent signal-to-noise ratio (> 35,000:1 at 4 cm⁻¹, 1 min scan), and long-term stability—critical for reproducible spectral acquisition in GxP-compliant workflows. Designed and manufactured in Ettlingen, Germany, the Tensor 27 integrates a robust, maintenance-optimized architecture featuring an air-cooled DTGS detector, automated alignment routines, and a sealed, purged optical bench to minimize atmospheric CO₂ and H₂O interference. Its modular design supports interchangeable sampling accessories—including ATR, transmission cells, reflectance modules, and gas cells—enabling seamless adaptation to diverse sample matrices without hardware reconfiguration.

Key Features

• Permanently aligned interferometer with dynamic alignment correction for zero drift over extended operation
• High-stability, temperature-controlled IR source and precision-machined mirror drive mechanism
• DTGS (Deuterated Triglycine Sulfate) detector with integrated preamplifier and low-noise electronics
• Standard spectral range of 7,800–350 cm⁻¹ (extendable to 12,500–250 cm⁻¹ with optional components)
• Real-time spectral acquisition at up to 10 spectra per second, supporting kinetic and reaction monitoring applications
• Integrated purge interface compatible with dry air or nitrogen supply to maintain optical path integrity
• Front-panel touchscreen interface with intuitive navigation and embedded diagnostics

Sample Compatibility & Compliance

The Tensor 27 accommodates solid, liquid, gel, and gaseous samples via standardized, ISO-compliant accessories. Common configurations include diamond ATR for direct analysis of polymers, pharmaceutical tablets, and biological tissues; demountable liquid cells with CaF₂ or BaF₂ windows for solvent-based solutions; and specular reflectance stages for thin-film characterization. All refurbished units undergo full functional validation per Bruker’s service protocol, including wavelength accuracy verification (NIST-traceable polystyrene film), photometric linearity assessment, and baseline stability testing over 24 hours. The instrument meets essential requirements for GLP, ISO 17025, and USP infrared spectroscopy guidelines. Data integrity is supported through audit-trail-enabled software (OPUS v7.5+), compliant with FDA 21 CFR Part 11 when deployed with appropriate IT controls.

Software & Data Management

Controlled by Bruker’s OPUS spectroscopy software suite, the Tensor 27 provides comprehensive data acquisition, processing, and reporting capabilities. OPUS includes advanced algorithms for baseline correction, peak deconvolution, spectral subtraction, and multivariate analysis (PCA, PLS). Method templates ensure consistent parameter sets across users and shifts. Raw interferograms and processed spectra are stored in Bruker’s proprietary .0 format, fully convertible to JCAMP-DX for third-party integration. The software supports automated report generation with embedded metadata (operator ID, timestamp, instrument serial, calibration status), electronic signatures, and secure user role management. Network deployment enables centralized method libraries and remote instrument monitoring—essential for multi-site QC laboratories operating under harmonized SOPs.

Applications

The Tensor 27 serves as a foundational tool in pharmaceutical development (excipient compatibility studies, polymorph screening, coating thickness verification), polymer science (additive identification, degradation kinetics, copolymer composition), environmental analysis (microplastic characterization, soil organic matter profiling), and food safety (adulterant detection, authenticity verification, moisture content modeling). Its reliability in routine identity testing—per USP , EP 2.2.24, and JP 2.07—makes it especially valuable for laboratories requiring validated, cost-efficient alternatives to new-platform instrumentation without compromising metrological rigor.

FAQ

Is this unit factory-refurbished or third-party serviced?
All Tensor 27 systems are refurbished exclusively by Bruker-certified service centers using original spare parts and documented calibration procedures.
Does the refurbishment include a warranty?
Yes—each unit ships with a 12-month comprehensive warranty covering parts, labor, and technical support.
Can the instrument be integrated into LIMS or ELN platforms?
Yes—OPUS supports ASTM E1384-compliant data export and offers optional API modules for direct LIMS connectivity.
Are original manuals and software licenses included?
Full documentation set (user manual, service manual, certificate of conformance) and a perpetual OPUS license are provided with each system.
What is the typical lead time for delivery and installation?
Standard delivery is 4–6 weeks after order confirmation, including pre-shipping performance verification and on-site commissioning by certified field engineers.
