Synkera
offers monodisperse nanoporous ceramic membranes that
are produced from nanoporous anodic
aluminum oxide. Synkera's membranes feature a symmetrical
nanoporous architecture with uniform cylindrical pores
penetrating the entire thickness of the membrane, and
are characterized by a high degree of pore ordering
and narrow pore size distribution (standard deviation
is typically better then 8%, and in some cases is as
low as 5%).
Synkera's ceramic membranes have superior mechanical
and thermal stability far exceeding that of anodic alumina
membranes from other suppliers. As-prepared anodic alumina
membranes are amorphous, but could be converted to nanocrystalline
gamma and alpha-alumina phases which further enhances
the membrane's chemical and thermal stability. Synkera
offers several membrane heat-treatment options for operating
temperatures up to 1000°C.
The range of currently available membrane specifications
is summarized in the table below. We maintain an inventory
of membranes with standard specifications. Most of our
ceramic membranes could be ordered with a pore diameter
in the range from 10 to 90 nm, and the thickness from
15 to 100 microns. For more details on this product,
please see Technology

Based on our expertise in materials science, nano-
and microfabrication, and using this featured AAO membrane
as a platform, Synkera is developing a portfolio of
membrane products for the following applications:
gas separation membranes
membrane-reactors
ultra- and nanofiltration membranes
membranes for bioseparation and bioanalysis
membrane standards
Partnerships are welcomed for joint application development
in these and other areas. Please contact
