Jenway 6850/230V – 6850 Double Beam Spectrophotometer

• Integrated user interface for local control
• Variable spectral bandwidth 0.5, 1, 2, 4 and 5nm
• Conforms to European Pharmacopeia requirements
• Jenway Prism PC software included as standard

The new 6850 introduces the first double beam spectrophotometer with a variable spectral bandwidth into the Jenway range. The highly stable optics and two detectors measure the sample and reference simultaneously optimising measurement accuracy. The 6850 has measurement modes for photometrics, concentration, multi-wavelength, spectrum scanning, kinetics, quantitation, DNA and protein analysis. Up to 10 wavelengths can be measured in the multi-wavelength measurement mode and quantitation curves can be created by measuring up to 10 standards at 3 different wavelengths.

Improved Optics

Model 6850 covers the UV/visible wavelength range from 190 to 1100nm, with a variable spectral bandwidth, ranging from 5nm down to 0.5nm, using tungsten halogen and deuterium light sources. The range of bandwidths available allows a balance between resolution, accuracy and data precision to be maximised depending on the application; therefore providing a flexible platform to conform to multiple regulatory agencies for a variety of applications, all with one spectrophotometer.

Model 6850 has three scan speeds available enabling scan speeds of 100 to 2000nm/min to be achieved. With wavelength scan intervals of 0.1, 0.2, 0.5, 1, 2 or 5nm the 6850 can be con?gured to meet your exact requirements.

Instrument Design

Model 6850 has an integrated user interface providing local control of the spectrophotometer. With no PC required this saves expense and valuable bench space. The large graphical display is easy to read and enables more information to be displayed including spectrum and kinetics curves. The user interface can be navigated using soft key navigation, arrow keys or shortcut keys.

This spectrophotometer utilises a research grade monochromator for excellent energy throughput and a silicone photodiode detector. All of this comes packaged in a small footprint double beam spectrophotometer whilst still offering a large sample chamber that enables an 8 position cuvette changer to be fitted.

Introducing Jenway Prism PC Software

Jenway Prism PC software is supplied as standard and offers additional functionality, extensive post-measurement tools, unlimited results saving and easy export of data.

The Prism PC software can be used to fully control the functionality of the spectrophotometer. The measurement modes available in Prism mirror those of the instrument with measurement modes for photometrics, concentration, multi-wavelength, spectrum scanning, kinetics, quantitation, DNA and protein analysis.

Prism has pre-loaded methods for DNA analysis including 260/280 and 260/230 ratios with 320nm correction. Up to 20 wavelengths can be measured simultaneously in the multi-wavelength measurement mode and quantitation curves can be created by measuring up to 200 standards.
