New range of HPLC 17mm, 30mm Syringe Filters
New Filter Design Drawing
The Superpure 17 mm and Superpure 30 mm syringe filters
manufactured by Membrane Solutions are designed to speed up
and increase sample volume throughput while reducing thumb pressure.
The 17 mm and 30 mm sizes, replacing the 13 mm and 25 mm sizes,
offer far more value to researchers due to several new features.
They will be available with one of the following membranes in 0.22µm
or 0.45µm pore size: Nylon66 , MCE, PTFE, PES and PVDF. These
filters should mainly be used for small sample volumes where the dead
volume should be kept to a minimum.
Improved Performance Benefits:

This table offers general guidelines for membrane characteristics and compatible applications.
Membrane Type
Membrane Characteristics
Applications
Nylon66
Most frequently selected membrane; broad compatibility with aqueous and organic
samples; naturally hydrophilic membrane; extremely low in extractables; excellent
flow rate with most sample matrices; not compatible with strong acids or bases
General laboratory filtration; filtration for
most HPLC samples. NOTE: Nylon binds
protein,
do not use when high protein
recovery is desired
Polyethersulfone
High flow rates with good throughput volume; low protein binding; compatible with
high temperature liquids; mechanically strong membrane low in inorganic extractable
ions
PES is certified for Ion Chromatography;
Tissue Culture filtration; filtration of
proteins and nucleic acids
PTFE
Hydrophobic membrane is resistant to nearly all solvents, acids, and bases; membrane
is mechanically strong and will withstand exposure to high temperature liquids; low in
extractables; PTFE blocks water vapor; can be used to filter aqueous solutions
Filtration of aggressive organic, highly
basic or hot solutions, ideal for transducer
protectors
Hydrophilic PTFE Hydrophilic PTFE is especially useful in HPLC sample preparation and is highly
resistant to most solvents. And it’s generally used 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 to CA
Aqueous sample preparation
PVDF
High protein binding, Hydrophobic membrane is resistant to nearly most solvents acid
and bases.
