Peristaltic Pump - SmartShield™ Peristaltic Pump Tubing |
 |
Performance
SmartShield™
tubing provides a pure PTFE bore for product contact and a
resilient Santoprene™ elastomer cover for unsurpassed
durability, even at back pressures approaching 60 psig. The
PTFE bore eliminates absorption of preservatives as well as
leaching of plasticizers into the process stream. The
elastomeric cover provides resilience for excellent flow
rate stability and long flex life. |
|
|
|
SmartShield™
tubing complies with FDA guidelines (21CFR177), and
has passed USP Class VI, cytotoxicity, and
physicochemical testing at an independent
laboratory. SmartShield™ tubing also complies with
the latest bioprocess equipment (BPE) guidelines. A
complete validation guide is available upon request. |

SmartShieldTM tubing lasts 10 times longer than FKM
tubing
and
is unaffected by recirculating hydrocarbon
fluid (Watson
Marlow
313T running at 400 rpm
with 6.4 mm ID by 2.4 mm wall tubes) |
Long Life &
High
Purity
SmartShield™ tubing utilizes a pure PTFE bore that is bonded
to a Santoprene™ elastomer cover. In comparison testing with
recirculating water and hydrocarbon fluid in a Watson Marlow
313T pump, SmartShield™ tubing lasted six to ten times
longer than competitive fluoroelastomer tubing and was
unaffected with pumping hydrocarbon solvent. SmartShield™
tubing is compatible with polar and non-polar organic
solvents, chemical intermediates, strong acids and bases, as
well as particulate filled solutions. The pure PTFE bore
enables one to pump fluids that would readily degrade
competitive elastomer tubing. Fluid immersion testing has
demonstrated that SmartShield™ tubing prevents solvents and
other chemicals from attacking the elastomeric cover. The
PTFE bore also eliminates concerns about leaching which
would interfere with high purity applications.

Steam-in-place &
Clean-in-place capability
The unique PTFE structure
enables SmartShield™ tubing
to be steam-in-place
sterilized at 30 psig
saturated steam pressure for
biopharmaceutical and other
sanitary applications. The
PTFE bore provides universal
chemical resistance which is
resistant to all
clean-in-place solutions.
SmartShield™ tubing can
withstand significant
pressure compared to
unreinforced tubing. The
hydrostatic burst pressure
of SmartShield™ tubing
ranges from 280 to 500 psig,
as shown in the figure below
and right. |

PTFE
structure enables high
pressure pumping
SmartShield™ tubing,
equipped with hydraulically
crimped fittings, provides
high pressure capability for
peristaltic pumping.
Fittings are available in
sanitary clamp type, cam &
groove, pipe thread,
compression, and barb style
in materials such as
stainless steel, PFA and
PTFE. Other fittings are
available upon request. The
unique PTFE structure of the
bore enables millions of
flex cycles at elevated
pressure. In typical
applications, SmartShield™
tubing can withstand more
than 1,000 hours of
continuous use, depending
upon the pump design and the
tube dimensions.

Lowest Absorbtion Tubing
SmartShield™ tubing also
prevents the absorption and
leaching of chemicals either
into or out of the tubing
wall. In the case of
preservatives, such as
methyl and propyl parabenes,
SmartShield™ tubing stands
alone in preventing
absorption due to the PTFE
liner, as illustrated in the
chart at right. Thus, finished
drugs retain their proper
amount of preservative and
thus their integrity.
Likewise, SmartShield™
tubing eliminates leaching
of plasticizers and process
aids commonly found in
thermoplastic and thermoset
elastomer tubing. TOC values
are dramatically reduced due
to the PTFE liner. As a
result, SmartShield™ tubing
affords the highest purity
processing available today.
