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.

“sterile”

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.
