Membrane Configurations
Through a range of proprietary and industry-standard methods, we’re able to offer various membrane configurations to meet your unique needs.
Nanoporous Silicon Nitride (NPN)
Unmatched capabilities
SiMPore’s innovative nanoporous silicon nitride (NPN) provides unparalleled permeability, optical transparency, and precision pore sizes – all in the same membrane material.
Patented manufacturing
Through a patented manufacturing process, nanopores are randomly created within a Silicon Nitride (SiN) layer of nanometer thickness; this process produces a very high pore density and thus highly permeable membranes.
Reduces inefficiencies
These NPN membranes are atomically flat and chemically inert, enabling markedly reduced biofouling and nonspecific interactions across a wide array of sample types.
Microporous & Microslit Silicon Nitride (SiN)
Uniform design
SiMPore fabricates microporous and microslit membranes within low-stress silicon nitride layers deposited on prime-grade silicon wafers. These porous features are uniformly, photolithographically patterned and etched.
Resilient thickness
Current products offer 10-20% porosity in a robust 400 nm thick membrane for demanding flow-based applications.
Microporous G-FLAT® Silicon Dioxide
Proprietary wrinkle-free substrate
Our microporous G-FLAT™ silicon oxide membranes are manufactured with a patented method, yielding a flat, porous, and glass-like layer. Current silicon nanomembranes are available with 5-20% porosity in a 300 nm thick membrane that is optically transparent.
Directly patterned
These membranes are directly patterned using photolithography, resulting in uniform pore sizes.
Custom Porous Membrane Chip Formats
Thickly framed
Currently available Membrane Chips feature a 5.4×5.4 mm, 310 µm thick silicon frame.
Custom specifications
Specific formats and related dimensions for various membrane thicknesses and membrane surface area per chip are listed below. The number of membranes per chip, as well as the membrane thickness (t), will vary depending on membrane product type.
