PE Polyester White Drain Discs, 47mm, Nonsterile, 200/Pk SKU: DD18535

Polyester (PET) Drain Membrane Filters - DD18535

Designed to deliver reproducibility and confidence across critical sample types, the Tisch DD18535 provides the filtration consistency that method validation demands. Equally important, robust polyester fiber construction offers excellent chemical compatibility with a wide range of organic solvents used in industrial filtration processes. Ultimately, precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• Spontaneous aqueous wettability reduces sample preparation time and eliminates the risk of solvent carryover from pre-wetting procedures.
• Low extractable levels ensure the drainage layer contributes no measurable background interference to downstream analytical measurements.
• Chemically inert polyethylene terephthalate construction resists degradation from common laboratory reagents, buffers, and biological fluids.
• Polyester drainage mesh provides a defined flow channel between membrane layers in multi-stage filtration stacks and lateral flow devices.
• Stable performance at operating temperatures reaching 80°C ensures the membrane handles heated applications without pore distortion or structural compromise.

Scaling from development to routine production requires membrane consistency at every lot, and the documented specifications provide the reproducibility needed to validate the filtration step once. Controlled mesh density delivers the consistent lateral flow distribution your device manufacturing requires for reproducible unit-to-unit performance. 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.
