OIL ANALYZER-UNUSED GRAPHITE FURNACE ATOMIC ABSORP-
TION SPECTROMETER
An absolute beauty!! Made by Perkin Elmer for the mili-
tary to measure concentrations of wear metals in air-
craft lubricating oil. It is a complete system with built
in microprocessor, display and printer. Considered
portable, it consists of two units in separate cases with
interconnecting cables and a third very strong shipping
case that holds everything. The analyzer can simulta-
neously measure (in parts per million) the concentrations of nine metals.
The instrument is easy to operate. Simply introduce a small sample of your
oil, water or fluid you want to analyze into the graphite tube in the furnace
using the supplied injector probe and press the start button. After the
automatic analysis cycle (about 1.5 minutes) is completed, the unit prints out
onto paper tape the metal concentrations.The optics in this thing are
impressive. There are two hollow cathode lamps (HCL) that provide the
spectral line sources for the metal analysis for iron, silver, aluminum,
chromium, copper, magnesium, nickel, silicon, and titanium. The transfer
optics consists of mirrors that combine the spectral output light beams of
the two HCLs into a single light beam. The light beam is transmitted thru
the graphite furnace tube (the furnace reaches temperatures up to 3000
degrees C and actually vaporizes the metals in the sample) and onto the
entrance slit of the polychromator. The spectral light is focused onto a dif-
fraction grating and the nine spectral lines unique to the metals are sepa-
rated and positioned on the focal plane. At each focal plane position is an
exit slit and the secondary optics measures each light output.In addition to
the complete instrument, you get 20 extra graphite tubes, 6 calibration
standards, other supplies, a tool kit, and Operation & Maintenance instruc-
tions with illustrated parts breakdown. Unused and in mint condition.
Original cost was $70,156.36 each!! Our price is less than 2% of what our
government originally paid for them. Looks like they bought more than they
needed. Sorry, but we are not allowed to ship these outside of the
United States

TRIPLE BEAM BALANCE
A single pan, low form balance that has three beams
with centre indicating sliding weights giving total weigh-
ing capacity of 610g. Supplementary weights are
included to extend the capacity to 2610g. Spring
loaded zero adjust compensator and magnetic damping
are provided. Stainless steel pan is of 150mm diame-
ter. Beams: 0-500g x 100g; 0-100g x 10g; and 0-10g x
0.1g. Unused.
