Description
The UV-2700, with its low stray light diffraction grating, is a spectrophotometer that offers an extremely wide photometric range. Traditionally difficult-to-measure high-absorption samples can now be easily measured. It is the ideal instrument for measuring samples which cannot be thinly sliced, diluted or subjected to other pretreatment procedures. Here, we introduce examples of measurement of high-absorption samples using the UV-2700.
Capable of 8-Abs Measurements
With the capability to perform exact transmittance measurements to 0.000001 %( 1 part in 100 million), the UV-2700 can be applied to assessing the transmission features of polarization films. Furthermore, even high-concentration samples can be measured without diluting, adding to savings in power use.

Spectral Comparison of Aqueous Potassium Permanganate Solutions
This spectrum is measured from an aqueous potassium permanganate (KMnO4) solution. In contrast to conventional models, this system is capable of high-level absorbance measurements.
Reduced Size and Power Consumption
The installation space necessary for this system has been decreased by around 28 % in comparison to conventional models*, as a result of a brand new compact design. Furthermore, the cooling fan is built into the side of the unit, so that it can be pushed back close to the wall. By positioning in contact with the wall, limited bench space can be more effectively used. Additionally, power consumption has been decreased to 170 VA, a 10 % energy savings which makes the system more environmentally friendly.
