Jenway Model 6705 Scanning UV/Visible Spectrophotometers

UV/Visible range, 4nm SBW spectrophotometer fitted with single 10 x 10 mm cuvette holder, 1GB of internal memory, 1GB SD/USB memory card, 100 disposable cuvettes, instruction manual, power cable and PC software on CD ROM with interface cable.


• Colour touch screen display
• High quality, sealed split beam optics for optimum photometric performance
• Secure multi-user operation
• Save to SD/USB memory cards
• Enhanced productivity
• Extensive range of accessories for flexibility and improve productivity

All three instruments have modes for photometrics, spectrum scanning, multi-wavelength analysis, kinetics and quantitation, giving direct concentration results against single or multi-point calibrations. With extensive post measurement tools to ensure results are presented exactly to each users requirements the 67 series also offers significant advances in data portability.

Together, the touch screen and colour display give the fastest, most flexible instrument interface possible. Where fine cursor control is required, using the QWheel™ makes the task easy and precise.

Jenway have developed Secure Multi User Operation for when instruments are shared by a number of users, so access to the instrument functions is controlled through a secure log-in procedure. For maximum security PIN codes can be allocated to individuals, groups or departments and to further increase flexibility each method can be given three levels of security:

• Public access is free to all users.
• Read only methods can be accessed by all users, but only modified by the originator.
• Personal method can only be accessed by the logged in user

The high capacity internal memory of the 67 series can be configured from 256MB, enabling over 1000 methods and results to be stored, up to 2GB, which stores more than 10,000 methods and results.

Removable SD or SD/USB memory cards further increases the flexibility and data transfer and enables the direct transfer of results to a PC via a USB port. Here all data can be viewed, exported, saved or printed for generating reports and standard operating procedures. Copying the SD card to the instrument's internal memory enables the easy cloning of multiple instruments, ensuring common laboratory practice and speeding set-up in busy teaching establishments.
