PE Polyester White Drain Discs, 10mm, Nonsterile, 500/Pk SKU: DD18532

Polyester (PET) Drain Membrane Filters - DD18532

Precision-manufactured hydrophilic membrane with a verified 40.0 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. In addition, chemically inert Polyester (PET) Drain web supports the primary filtration media without introducing extractables or contaminants into the filtrate stream. Lot-level verification of pore size, flow rate, and physical dimensions ensures that membrane performance remains predictable when scaling from method development to routine analysis.

Material Specifications

• Non-sterile configuration is suited for analytical sample preparation, mobile phase filtration, and other workflows where pre-sterilization is not required.
• Mechanically flexible PET construction integrates into multi-layer device assemblies without cracking or delamination during converting operations.
• Thermal stability of the membrane material allows safe operation at temperatures up to 80°C without degradation of retention characteristics or dimensional integrity.
• Chemically inert polyethylene terephthalate construction resists degradation from common laboratory reagents, buffers, and biological fluids.
• Open mesh architecture maintains uniform fluid distribution across the downstream membrane surface, preventing channeling and uneven flow patterns.

Multi-site studies where different laboratories must produce comparable data benefit from membranes manufactured to tight specifications, giving you confidence that site-to-site variability is not introduced by the filtration step. To meet this need, autoclavable polyester construction supports reuse in your validated protocols, reducing the consumable cost of multi-layer filtration assemblies. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.

• Multi-Layer Filtration - Separates membrane layers in stacked filter assemblies to maintain independent flow paths and prevent adhesion.
• Fluid Distribution Layer - Maintains uniform sample contact across the full membrane surface area in vacuum and gravity filtration setups.
• Blood Separation Devices - Acts as the drainage layer beneath plasma separation membranes, directing filtered plasma to collection zones.
• Lateral Flow Devices - Provides the defined drainage channel that controls fluid transport velocity across detection and capture zones.
• Absorbent Pad Support - Provides structural spacing between absorbent pads and reactive membranes in immunoassay device assemblies.
• Device Prototyping - Offers consistent mesh specifications across lots for repeatable performance during filtration device development cycles.
