Scharlau syringe filters are used mainly for
filtering small aqueous and organic samples prior to chromatography injection.
The filtered samples ensure column protection. The filter housing is made of
pure PP. The result is a high quality syringe filter fulfilling the needs of
the most demanding chromatographers.
Nylon: nylon syringe filters have become the
"standard" material due to their wide chemical compatibility and
their hydrophobic nature. They can be used for filtering aqueous samples and
most solvents.
Regenerated cellulose: the regenerated syringe
filters have a lower protein retention than those made of nylon and are less
extractable than PVDF. Ideal for aqueous solutions.
PVDF: polyvinylidene fluoride syringe filters are
indicated for the filtration of protein samples due to their very low retention.
PTFE: syringe filters made of PTFE and have the
lowest extractables levels and the widest chemical compatibility. They are
especially suitable for filtering solvents due to their hydrophobic nature.
Designed for filtering the most aggressive solvents, and strongest acids and
bases.
PP: filters of hydrophobic PP (polypropylene),
great resistance to solvents, very low protein binding and good thermal
compatibility. They are used for general filtration of biological samples,
solvents, deionized water. Commonly used for UHPLC.
PES: The new sterile syringe filters Scharlab PES
(polyethersulfone) of 25mm diameter, 0,22µm and 0,45µm pore size. These filters
are commonly used in molecular biology, filtration of culture media since they
have a very low protein binding, high performance and low extractables level,
providing maximum recovery
