What is polycarbonate membrane filter?

Polycarbonate Track Etch (PCTE) membranes are made from a thin, microporous polycarbonate film material. It is ideally suited for use in blood assays and high-purity and general filtration.

What are polycarbonate membranes?

polycarbonate membranes are true pore size microporous membranes featuring the sharp cut-off and reproducible microfiltration characteristics of track-etched membrane filters. Cytiva business offers a variety of Whatman PCTE membrane filters for gravimetric analyses.

What is Isopore membrane filter?

The Isopore membrane is a polycarbonate, track-etched screen filter recommended for all analyses in which the sample is viewed on the surface of the membrane. Isopore membrane offers distinct advantages for the analysis of airborne contaminants and other particles using optical or electron microscopy.

How do I choose a filter membrane?

Selecting Right Membrane Syringe Filter 1. Choose the size of filter based on the volume of sample that must be filtered. 2. Choose the porosity of the filter based on the size of potential particulates that may be present in your sample.

What are track etched membranes?

Track etched membranes are porous systems consisting of a thin polymer foil with channels from surface to surface. Latent ion tracks are the result of the passage of swift ions through solid matter and they can be etched selectively. As a result, conical, cylindrical or other shape channels can be obtained.

What is the advantage of track etching?

Track-etch membranes offer distinct advantages over conventional membranes due to their precisely determined structure. Their pore size, shape and density can be varied in a controllable manner so that a membrane with the required transport and retention characteristics can be produced.

What is Isopore?

The Isopore™ membrane is a polycarbonate, track-etched screen filter recommended for all analyses in which the sample is viewed on the surface of the membrane. Isopore™ membrane offers distinct advantages for the analysis of airborne contaminants and other particles using optical or electron microscopy.

What does track etched mean?

Etching of the Tracks. The irradiation of polymer membranes with swift heavy ions creates tracks in the material that are essentially damaged parts in the membrane caused by the passing high-energy ions. Second step of the nanopore fabrication process is the chemical etching of these tracks in electrochemical cells.

What is track etched membrane?

Track Etched Membrane is a high-precision manufactured film used in critical applications for Life Sciences, automotive, industrial and consumer markets. Specified pore diameter is tight, with each pore associated with a single channel through the membrane.

What Cannot be a size of membrane?

What cannot be a size of membrane? Explanation: A membrane cannot be nano porus.

What are the two types of membrane?

The two main types of epithelial membranes are the mucous membranes and serous membranes.

What is difference between PVDF and PTFE filter?

The big difference between PTFE and PVDF is that PTFE membranes can be used in the filtration of strong acids and aggressive solutions, but PVDF membranes are more suited for the filtration of non-aggressive aqueous and mild organic solutions. Also there are some similarities between these two membranes.
