Teflon/Silicone Discs
Unique discs that combine the inertness of a Teflon coating
with the resealability of silicone.
Autoclavable Thermo Scientific Teflon/Silicone Discs are
specifically designed to combine the resealability of
silicone with the inertness of a Teflon coating. Many
sizes are available to fit our Hypo-ViaI and Reacti-Vial
Screw Cap.
Structurally bonded (not cemented) Teflon coating to
silicone. No cement to be leached or baked out of your
sample after needle penetration.
Highlights:
• Reseals instantly puncture after puncture
• Compresses, giving it a “lock-washer” effect in
maintaining a tight seal, and forces the Teflon coating to
conform to the sealing surface
• No bent needles from a septum that is too hard; standard
syringe and CC needles penetrate the entire disc with
ease
• Protection of Teflon coating: The Teflon layer is a full 10
mils thick

Teflon/Rubber Laminated Discs
For a highly inert and nonreactive seal.
Thermo Scientific Teflon/Rubber Laminated Discs are
constructed of white pharmaceutical rubber with 5 mils of
Teflon coating bonded to one side. Total thickness of the
disc is approximately 60 mils. The discs are excellent for
use as cap liners when a highly inert nonreactive seal is
desired.
Our rigid Teflon/Rubber Laminated Discs are more difficult
to puncture than Teflon/Silicone Discs. Consequently, care
must be taken when puncturing these discs to avoid
bending the needle.
Our Teflon/Rubber Laminated Discs are auto-clavable and
demonstrate no loss of integrity after heating above 100°C
for 5 hours.
