Available 2 filters: Syringe filters with 0,45 µmpore size
Syringe filters with 0,22 µmpore size
Available 2 filters: Syringe filters with 0,45 µm pore size
Syringe filters with 0,22 µm pore size
Specially designed for HPLC sample preperations with the
best quality tear proven membranes. Fully autoclavable.
Since the housing is ultrasonically sealed they offer excellent
pressure stability.
Sample distribution rings of the body directs samples for
uniform filtration with a guarantee of high flow rate and filtration
speed on both directions restricting the liquid overload.
Unique female luer-lock secures connections with syringes.
Body design enables to be used with all robotic machines.
Membrane type and porosity printed on each filter. Different
colour coded sealing rings enable easy differentiation of the
membrane type.

PVDF: Hydrophilic membrane
For polar solutions, water-
soluble
oligomers
and
polymers like proteins, binding
capacity for proteins 20 µg per
25 mm filter.
CA: Hydrophilic membrane
For filtration of water-soluble
oligomers and polymers,
especially suited for biological
macromolecules,
extremely
low binding capacity for
proteins
21 µg per 25 mm filter.
PA:
Rather
hydrophilic
membrane
For aqueous and organic/
aqueous medium polar liquids.
RC: Hydrophilic membrane
with very low adsorption
For aqueous and organic
/ aqueous liquids i.e. polar
and medium polar sample
solutions.
Binding capacity for proteins
84 µg per 25 mm filter.
PES: Hydrophilic membrane
For aqueous and slightly
organic liquids with higher flow
rates, very low adsorption for
pharmaceuticals and proteins,
good stability against acids and
bases.
MV: Hydrophilic membrane
with very low adsorption
For aqueous or polar solutions
PTFE: hydrophobicmembrane
For nonpolar liquids and
gases which are resistant to
all kinds of solvents flushing
with alcohol, followed by water,
makes the membrane more
hydrophilic.
PET: Hydrophilic multi-
purpose membrane
For polar as well as nonpolar
solvents, not cytotoxic, does
not block the growth of
microorganisms and higher
cells.
