SYRINGE FILTERS -
“non-sterile”
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 direct 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.
MV =
cellulose mixed esters,
CA=
cellulose acetate,
RC =
regenerated cellulose,
PA=
polyamide,
PTFE =
polytetrafluoroethylene,
PVDF =
polyvinylidene difluoride,
PES =
polyethersulfone,
PET =
polyester
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 / aque-
ous liquids i.e. polar and medium
polar sample solutions.
Binding capacity for proteins 84µg
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 multipurpose
membrane
For polar as well as nonpolar
solvents, not cytotoxic, does
not block the growth of
microorganisms and higher cells.
