SPECTROSCOPY
BEST PRICED IR SPECTROPHOTOMETER The new Hilger & Watts H-1200 Infrared Spectrophotometer, distributed exclusively in the United States by Wilks Scientific is not only the lowest priced instrument of its type available but offers versatility and performance provided only by much higher priced instruments. FASTEST PRODUCTION OF SPECTRA The Infragraph’s outstanding capability of recording complete spectra with excellent resolution and low noise in less than 2 minutes, multiplies the output of useful data. One instrument does the work of several and saves investment for additional equipment. 1 Vz min. polystyrene scan shows spectral quality at high speed comparable to expensive high-performance instruments
BROADER ACCESSORY CAPABILITY Separated sample and reference beam compartments in the Infragraph’s unique optical arrangement increase doublebeam accessory adaptability. The application-oriented and budget-minded investigator will welcome the Infragraph’s accommodation of Wilks Scientific's complete line of standard and special IR accessories. RUGGED AND RELIABLE Rugged construction using quality components and solidstate electronics have produced excellent reliability records for the many instruments already installed in Europe. Service personnel and stocks of spare parts or supplies are available at Wilks Scientific to ensure uninterrupted operation.
Sample- and reference-beam “corner design” offers enhanced freedom of accessory selection
