Asymmetric Membranes
Asymmetric Membranes
Synkera offers asymmetric ceramic membranes for liquid (such as nano- and ultrafiltration) and gas filtration, as well as for other applications. As many of our products, these membranes are made from monolithic nanoporous anodic aluminum oxide (AAO) and are characterized by very uniform pores in the active layer. The membranes also feature a novel architecture with a very thin and uniform active layer. Such attributes address the need for membranes with improved selectivity, higher permeance, reduced fouling and better durability.
Structure of Synkera Asymmetric Membranes
Membrane Features & Benefits
- Narrow pore size distribution (standard deviation is typically better than 10%) and sharp molecular weight cutoff (MWCO)
- Pore diameter and MWCO values are highly reproducible and selectable in a broad range (pore diameter from 1 nm to 200 nm; MWCO 5 to 300 kDa)
- High pore density in a very thin active layer and large pores and high porosity in the support layer enable water permeance up to 5•10-8 cm/s/Pa
- Smooth surface and uniform pores reduce fouling
- Made of non-toxic and biocompatible alumina with no extractables and no product contamination
- Good mechanical durability and resistance to abrasion
- Immune to organic solvents and radiation
- Reliable compression sealing using an optional aluminum rim
- Planar membranes available in a variety of standard and custom sizes and shapes. Scalable up to 1 sq. ft.
As-prepared membranes contain amorphous boehmite phase, which is suitable for short (<3 hrs) exposure to aqueous solutions. Polycrystalline membranes, composed from gamma and alpha-alumina phases with significantly enhanced chemical and thermal stability, are also available.
