GILFORD STASAR III SPECTROPHOTOMETER SET

 

 

Gilford (A Corning Laboratory Sciences

 

 

 

 

Company) Stasar III Spectrophotometer.

 

 

A highly accurate reference spectropho-

 

 

tometer operating in the visible portions

 

 

of the spectrum from 335 nm to 700nm.

 

 

Linear measurements of absorbance or

 

 

concentration are displayed on a bright, easy-to-read

LED readout. Consists of a tungsten light source, dif-

fraction grating monochromator (wavelength accuracy

+or- 2nm, and stray less than 0.3% throughout the wave-

length range), linear absorbance photometer, and a four-

place LED readout. Provisions are included for printers,

auxiliary analog equipment, and computer inputs for

remote control of sample and purge. This is the com-

plete set in a large military transit case including air

pump, vacuum receiver, spare parts, cuvettes, operators

manual, service manual, and dual calibration standard.

Includes certificate of calibration. Appears to be

unused. Sorry, but we are not allowed to ship these out-

side the United States. Only have a few.

WOLLENSAK HANDHELD DIRECT VISION SPECTROSCOPE WITH WAVELENGTH SCALE

This is a beauty! Portable and precise, the instrument provides direct wavelength readings of visible spectrum from 400nm to 750nm with each scale division repre- senting 5nm. The spectrum is viewed in the plane of scale and for error free readings, the D-line (wave- length of sodium light) on the scale can be adjusted.Great for demonstrating spectra from any

visible light source. Precision made heavy duty stainless steel construction with an Amici type 3-element prism assembly with angle dispersion C-F 5 degrees, variable optical slit and adjustable eyepiece. Easy to use: Optical slit adjusts by rotating the knurled end piece, and focus for both the scope and wavelength scale is slip type. Contrast and resolution of the spectrum is changed by adjusting the slit opening. Both emission and absorption spectra can be viewed. Compact 4-1/4" inches long by 1 inch diameter on the slit end and 1-3/4" wide on the eyepiece end. We have seen similar ones selling for $350.00 online. Lots of uses including gem studies. New with wood case. Wollensak quality optics since 1899.
