Nickel-clad fused silica
We take polyimide-coated fused silica
(FS) and remove the polyimide layer.Then
we electrochemically plate the FS with
pure nickel. The resulting nickel-plated
FS tube provides superior heat transfer to the FS lining,
permitting use as a flexible transfer line with the best qualities
of silica-lined stainless but with improved heat transfer and a
shorter bend radius. The 1/32" OD tubing is available in IDs
from .002" to .010". For high pressure applications, we
recommend using our 1/32" 316SS ferrules.
• Inert, flexible transfer lines
• Improved heat transfer
Nickel-clad polyimide-coated fused silica
Any polyimide-coated FS
can be electroplated with
pure nickel, resulting in
a ruggedized traditional
FS column (or transfer line
with deactivated FS),
which can be resistively
heated, if desired. Best of
all, it permits use of metal
ferrules for improved leak-
tight connections–perfect
for temperature program
applications.
1/32" OD tubing is available in IDs from .002" to .010". A thin-
wall, lowmass version optimized for resistive heat applications
is available with OD of .017" (48 VDC) or .019" (24 VDC). We
offer several options for tubing connections. Contact our tech
support to discuss your application.
• Improved heat transfer for
FS columns
• Permits resistive heating of
columns and transfer lines
• Allows direct connection using
metal ferrules
• Rated up to 20,000 psi (dependent on size and
plating thickness)
Nickel-clad PEEK
• Permits use of PEEK
tubing at 40,000 psi
• Direct connection
with metal ferrules
Since we can manufacture
virtually any size PEEK
tubing from 360 micron
OD/.002" ID on up, the
possibilities are endless.
In any size, the mechan-
ical properties of nickel combined with the chemical properties
of PEEK produce enhanced performance with robust metal
ferrule connections. We currently offer 1/32" OD tubing with
ID from .002" to .010", and 1/16" OD tubing from .0025" to .030".
