Condition: Used Jenway 6850 Double Beam UV/Visible Spectrophotometer Fully Tested & Functional | Minor Cosmetic Repair | See All Pictures We are pleased to offer a Jenway Model 6850 Double Beam UV/Visible Spectrophotometer . This is a high-specification, variable bandwidth scanning instrument suitable for a wide range of laboratory applications including pharmaceutical, life sciences, environmental, biochemistry, and teaching environments. The unit has been fully powered up and tested . All functions operate correctly and the display shows a clean, straight baseline — consistent with normal operation when no sample is present. The instrument is in full working order. Cosmetic Note: There is a crack to the trim which has been repaired with adhesive and is fully secure . This is a cosmetic issue only and does not affect the performance or operation of the instrument in any way. Please refer to all photographs carefully before purchasing as they form part of the item description. Key Specifications: Type: Double Beam UV/Visible Spectrophotometer Wavelength Range: 190 – 1100 nm Variable Bandwidth: 0.5, 1, 2, 4, 5 nm Wavelength Accuracy: ±0.3 nm Light Sources: Deuterium (UV) and Tungsten Halogen (Visible) lamps Detector: Silicon photodiode Connectivity: USB port for data transfer and storage Measurement Modes: Photometrics, Concentration, Multi-Wavelength (up to 20 simultaneous), Spectrum Scanning, Kinetics, Quantitation (up to 200 standards), DNA/RNA and Protein Analysis Software: The instrument operates fully as a standalone unit without any additional software. It is also compatible with Jenway Prism PC Software for full PC control, data capture, and advanced analysis — this software is not included but may be obtained directly from the manufacturer (Cole-Parmer / Jenway). What's Included: Jenway 6850 spectrophotometer unit As pictured — no software, cables, or accessories unless shown in photographs Condition: Used — fully functional. Minor cosmetic repair as described and pictured.

The Jenway 6850 is a UV/visible double beam spectrophotometer with a variable spectral bandwidth, designed and manufactured by Jenway (a Bibby Scientific / Cole-Parmer brand). It introduces the first double beam spectrophotometer with a variable spectral bandwidth into the Jenway range, featuring highly stable optics and two detectors that measure the sample and reference simultaneously to optimise measurement accuracy.

The 6850 is ideal for quality control, general research, pharmaceutical, biochemical, and clinical laboratory applications. It conforms to European Pharmacopoeia requirements and operates fully as a standalone unit via its integrated user interface, with no PC required. It is also compatible with Jenway Prism PC software for advanced data capture and post-measurement analysis.
