Description
FEP tubing isagreat
alternative to traditional PTFE
tubing, desirable foruse
because it ischemically inert to
most solvents, easy tocut, and
translucent foreasymonitoring
of solutionspassing through.
•Great forgeneral, low
pressureapplications
•Many sizesavailable
inmultiplecolors for
easy identification
•Tightmanufacturing
tolerances toensure
product consistency
Offersexcellent chemical
compatibility, plusdue to its
inner surface smoothness,
PFA tubing tends tobemore
translucent thanPTFE tubing.
•Offershigherpurity
andenhanced translucence
whencomparedwithother
fluoropolymer tubes
•Great formorecritical, low
pressureapplications
Thispolymer tubing is
manufactured fromapremium
gradeof PFA—oneof
themost contaminant-free
polymerson themarket.
•Offerschemical stability,
mechanical strength, and
purity for applications such
asmedical, diagnostic,
pharmaceutical,
biotechnology, and
semiconductor
•Excellent replacement for
PTFEwheregaspermeability
and surface textureare issues
•Clarityof tubingmakes
PFAanexcellent choice for
monitoringfluidmovement
This tubingoffersexcellent
chemical compatibility,
transparency, very low
contaminant levelsand
isavailable in themost
commonly-usedoutside
diameter for capillary
tubingapplications.
•Replacement for capillary
tubing in lowpressure
applicationswhereexcellent
chemical compatibility
is required
•Tubing sleevesavailable for
capillary tubingconnections
ETFE ischemically inert and
more suitable forhigher
pressureapplications (when
usingaqueousmobilephases)
thanPTFE, FEP, andPFA.
Additionally, becauseETFE is
more rigid thanPTFE, FEP, and
PFA, this tubingbetter resists
innerdiameter collapse.
•Excellent solvent resistance
•Moredurableand less
gaspermeable than
PTFE, FEP, andPFA
•Operating temperatures
up to80 °C
