T
he Glass Lined Stainless Desorption Tubes have an
inside diameter of 3.0 mm. Each tube is 4.0" long by 1/4"
diameter and is threaded on both ends. The inert glass
lining protects your samples during thermal desorption to minimize
analyte breakdown due to reaction with metal surfaces. After
conditioning and sample loading, the ends of the tubes can be
fitted with stainless steel caps with seals (sold separately) to
maintain the integrity of the sample until analyzed. PTFE seals
are normally used to seal the caps to the desorption tubes. These
same threads on the desorption tube provide the means of
connecting the desorption tubes to the connector tube and for the
attachment of the desorption tube needle. All tubes are serialized
for accurate identification of tubes and samples. Tubes are avail-
able empty or can be packed as listed on the next page.
Silco
TM
Coated Stainless Steel Desorption
Tubes
This thermal desorption tube is used in applications where a
larger I.D. is required (I.D. - 3.0 and 4.0 mm). The silco coating on
the inside of the thermal desorption tube still protects your sample
by eliminating the direct contact with the metal surface and thereby
minimizes the thermal reactions of analytes with the interior of the
desorption tube. The larger I.D. of this tube permits almost twice the
amount of sample or thermal desorption resin to be contained
inside the desorption tube. All tubes are serialized for accurate
identification of tubes and samples. Tubes are available empty as
listed below or can be packed as listed on the next page
Stainless Steel Desorption Tubes
This is a lower cost thermal desorption tube that can be used in
many applications where analytes are not thermally sensitive.
These tubes are constructed of stainless steel with no coating on
the walls. These tubes are currently available in 4.0 mm I.D, only.
All tubes are serialized. Packing of these tubes is also available on
special request.
