MetaFluorex™ is a highly ordered (hexagonal closed-pack), optically transparent, straight pore, ceramic thin membrane produced using NANOPEC proprietary biocompatible process.
Non Cytotoxic
In addition to achieving a high level of order, NANOPEC production does not use cytotoxic chemicals commonly present in the production of ordered AAO membranes. Chromium and Mercury-free guarantee biocompatibility for uses in the biopharmaceutical and health care industries, eliminating R&D artifacts, preserving cell viability. Made with the highest purity aluminum (99.999%) under carefully controlled conditions, MetaPurex exhibits notable physical and chemical properties. Read more.

Fluorescence Enhancement
​
The high transparency of and the absence of Cr+6 ions makes MetaPurex compatible with fluorescence bio-assays. These ordered high purity ceramic membranes provide over one order of magnitude fluorescence enhancement factor (>10x) which gives higher sensitivity to your existing bio-assays. Write to us at info@nanopec.com for a white paper explaining how the process works at the atomic level.
​
Mechanical Stability
​
MetaPurex offers high flexibility in large formats. This is due to the proprietary method to cut simple and complex shapes without the appearance of micro-cracks. Unlike other AAO membranes, MetaPurex does not require a polypropylene o-ring for safe handling, increasing the amount of area for the required bio-processing task at hand.
​
Thermal Stability
​
MetaPurex is thermally very stable. For applications requiring annealing we recommend 2-3 hours, 10 deg/min up to 400 Celsius. Use appropriate weight supports to avoid non-uniform annealing during internal thermal stress release.

​
Electrical Resistance
The electrical resistance of MetaPurex pore walls 10^14 Ω. This is 10,000 higher electrical resistance than silica glass. This is a ceramic material with high insulation properties. Ideal for manufacturing and insulating nano-wires
Chemical Resistance
​
MetaPurex shares the high chemical resistance characteristics of ceramics. It can withstand high acids, including to pH= -1.1 for several hours. It is not stable at high basic pH (>7.5) for long periods of time. It is quite stable under most organic solvents with very few exceptions.
​
Pore Structure
​
Pores are formed in a hexagonal array of oxide cells. The pores structure extends all the way through the ceramic membrane, 50-100 microns, an aspect ratio > 10,000. Films are closed pores at one end, membranes are through open pores.
