 6705UV/Visible Split Beam Spectrophotometer (4nm SBW)/6705B0

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

Model 6705 covers the UV/visible range of the spectrum and has a 4nm bandwidth. All three instruments in the 67 range 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 spectrophotometers also offer significant advances in data portability.

The 6705 UV/visible scanning spectrophotometer is fitted with a single 10 x 10mm cuvette holder and is supplied with 2GB of internal memory, 2GB SD memory card, 100 disposable cuvettes, instruction manual, power cable and PC software on CD ROM with interface cable.
