New range ofHPLC17mm, 30mmSyringeFilters
NewFilterDesignDrawing
TheSuperpure 17mm andSuperpure 30mm syringe filters
manufactured byMembraneSolutions aredesigned to speedup
and increase sample volume throughput while reducing thumb pressure.
The 17mm and 30mm sizes, replacing the 13mm and 25mm sizes,
offer farmore value to researchers due to several new features.
Theywill be availablewith one of the followingmembranes in 0.22µm
or 0.45µmpore size: Nylon66 ,MCE, PTFE, PES andPVDF. These
filters shouldmainlybe used for small sample volumeswhere the dead
volume shouldbe kept to aminimum.

MembraneCharacteristics
Applications
Nylon66
Most frequently selectedmembrane; broad compatibilitywith aqueous andorganic
samples; naturallyhydrophilicmembrane; extremely low in extractables; excellent
flow ratewithmost samplematrices; not compatiblewith strong acids or bases
General laboratory filtration; filtration for
most HPLC samples. NOTE: Nylonbinds
protein,
donot usewhen highprotein
recovery is desired
Polyethersulfone
High flow rateswith good throughput volume; lowprotein binding; compatiblewith
high temperature liquids;mechanically strongmembrane low in inorganic extractable
ions
PES is certified for IonChromatography;
TissueCulture filtration; filtrationof
proteins andnucleic acids
PTFE
Hydrophobicmembrane is resistant to nearly all solvents, acids, and bases;membrane
ismechanically strong andwill withstand exposure tohigh temperature liquids; low in
extractables; PTFE blockswater vapor; can beused to filter aqueous solutions
Filtrationof aggressive organic, highly
basic or hot solutions, ideal for transducer
protectors
HydrophilicPTFE HydrophilicPTFE is especiallyuseful inHPLC sample preparation and is highly
resistant tomost solvents. And it’s generallyused for aqueous-based biological
samples.
Filtration of aggressive organic, highly
basic or hot solutions, ideal for aqueous
filtration
MCE
Ideal for aqueous-based samples; high protein recovery from filtrate; higher tensile
strength compared toCA
Aqueous sample preparation
PVDF
High protein binding, Hydrophobicmembrane is resistant to nearly most solvents acid
and bases.
