HGA Pyrocoated Graphite Tubes and L’vov
PerkinElmer tubes are
manufactured to the highest
quality specifications
The production of high-quality graphite components requires stringent
quality control. To ensure high quality and consistency, a specific
grade of high-density base graphite material has been developed
for PerkinElmer’s exclusive use. This base graphite material is used
for the manufacturing of all PerkinElmer graphite tubes.
Selection and careful control of raw materials are extremely important.
The composition and the microstructure of the base graphite material
determine the specific resistivity of the tube and its heating characteristics.
When you purchase graphite supplies from PerkinElmer, you get the
results of our many years of experience with quality graphite parts.
The proper performance, maintenance, and serviceability of our
graphite furnace systems can be assured only through the use of
genuine PerkinElmer graphite components.
We have put 30 years of expertise
into the development of our graphite tubes,
contact cylinders and platforms
Contact Cylinders
Contact Cylinders
The graphite contact cylinders used in the HGA Graphite Furnace are
engineered for a precise fit so that variations in electrical contact — which
might affect the analytical performance — are reduced to a minimum. The
graphite contacts are shaped so that they completely encase the graphite
tube. Thus, the graphite tube is located in a defined
inert environment, which ensures uniform heating
conditions and long tube lifetime.
