New membrane technology offers higher flow rates

Tests conducted at SP Technical Research Institute of Sweden indicates that the flow rate of Porenix membranes is three to four times higher than that of conventional track-etched membranes. The higher permeability, in combination with other characteristics, is of interest for many applications, such as virus purification, emulsification in harsh solvents, and airborne particle analysis.

“We are convinced that our technology will allow even higher permeability, through continued product development. Optimization for different applications will enable time and energy savings as well as new possibilities in research”, comments Marcus Thorin, CEO of Porenix.

 The company develops and manufactures high-performance membranes, using modern nanotechnology developed at Chalmers University of Technology inGothenburg,Sweden. Founded in 2009, Porenix now markets a small portfolio of membranes for lab-scale use as well as custom-made membranes to meet particular needs.

 “In addition to high permeability, our membranes have a number of advantages for various applications. This includes high filtration recovery rate and excellent pore uniformity, which is beneficial in e.g. viral research, extrusion of liposomes and size-separation of monodisperse nanoparticles”, saysMarcus Thorin. “Another potential application is TEM windows for electron-microscopy, where the membranes transparency to electron beams is critical.”

 Porenix is at the moment looking for potential distributors and partners for co-operation in product and business development.

More about Porenix membranes…

The membranes developed by Porenix are made from silicon nitride, a ceramic material which is stable in both chemically harsh environments and high temperatures. The surface of the membranes is flat, which simplifies the use of microscopy, and the pores of the membranes are very uniform in regard to roundness and size. The membranes can be produced with a thickness of only 50 nanometers and with a pore diameter of 30–500 nanometers.

… and the company

Porenix uses modern nanotechnology to develop and manufacture high-efficiency filtration membranes. The membranes are ideal for applications that demand high permeability and high accuracy. Development of the technology is the work of Sarunas Petronis, researcher at Chalmers University of Technology, who is also the co-founder of the company. Porenix is a part of the Chalmers Innovation business incubator.
