Sterlitech PETE (polyester) Membrane Filters, 0.2 Micron, 200mm x 250mm

Sterlitech PETE (polyester) membrane filters are hydrophilic, solvent-resistant membranes made from a translucent, microporous polyester film. Designed for applications that require consistent pore control and high particle retention accuracy, these membranes are especially suited to blood assays, sample clarification, and microscopic analysis.

Key Features

Hydrophilic microporous polyester membrane
Highly solvent-resistant for broader compatibility
Smooth, flat surface for enhanced microscopic particle visibility
Precisely controlled pore size and density
Suitable for filtration, prefiltration, and diagnostic assay use

Precision Surface and Solvent Resistance

With a smooth, flat surface that enhances particle visibility, PETE membranes allow for efficient inspection and reliable capture of particles larger than the specified pore size. Compared to polycarbonate (PCTE) membranes, PETE offers similar structural properties with the added advantage of improved solvent resistance. These membranes are manufactured through a proprietary two-step track-etch process, ensuring precise control over pore size and density for reproducible performance.

Precise General Filtration and Prefiltration
Removal of red blood cells from plasma
Flow control of reagents through assay
