Thermo Fisher Scientific
Inc., the world leader in serving science, today announced a new Thermo
Scientific Diffuse Reflectance Accessory, specially designed to complement the
powerful Evolution(TM) 300 UV-Visible spectrophotometer. The DRA-EV-300 is a
cost-effective solution for material science and general QC measurements on
solid materials. At half the price of some competitive systems the new accessory
is affordable for a wide range of applications including inorganic chemistry,
solid state physics, optical materials, plastics, pigments, coatings and nano
powders. Further information on the DRA-EV-300 is available at www.thermo.com/dra300.
The Thermo Scientific DRA-EV-300 Diffuse Reflectance Accessory accommodates
a useable wavelength range of approximately 220 to approximately 1100 nm. In
competitive instruments, as much as three times more expensive, the extended
wavelength range is only 900 to 1100 nm. The internal coating of the DRA-EV-300
consists of a sintered PTFE material that enables excellent diffuse reflectance
performance across the entire wavelength range. Pre-aligned optical configuration
on a kinematic mount facilitates simple and convenient installation with no
The DRA-EV-300 also features horizontal reflectance sample mounting, safely
holding samples in place with gravity. Other systems require spring mounted
clips to hold a vertical sample in place which can often damage delicate surfaces.
The gravity mounting lets scientists easily perform multiple measurements on
a single spot of a sample without compromising integrity.
The DRA-EV-300 is designed to complement the Evolution 300, a high-performance,
double-beam UV-Visible spectrophotometer which incorporates a high intensity
and long life Xe flash lamp. The instrument achieves fast, reliable and flexible
scanning, fixed wavelength analysis and a variety of other measurements including
color calculations and various materials calculations.
