A thicker nitrocellulose membrane with added surfactant, creating a large-pore backed membrane (235 µm thick) for easy replacement of other membranes in lateral flow assays with minimal optimization work needed.
Reliable intra- and inter-lot consistency as demonstrated by a coefficient of variation (CV) for capillary rise of < 10%.
Enhanced consistency in application with minimal amount of unincorporated nitrocellulose powder (often referred to as “sticky dust”) on the surface of the membrane.
Reduced assay optimization costs, in terms of cost and time, as compared to a less consistent membrane.
Easily swapped into existing lateral flow assays without the need for a large redevelopment.
FFHP Plus Thick Membranes
FFHP Plus Thick membranes are part of the Whatman FFHP family of nitrocellulose membranes which are directly cast onto a plastic film. The membranes are a result of an improved casting procedure, which results in enhanced intra- and inter-lot consistency and sharper lines. The surface is uniform with minimal amounts of unincorporated nitrocellulose powder, whilst the fine structure fiber distribution provides large internal surfaces for binding proteins.
FFHP Plus Thick membranes are manufactured to the highest levels of quality and consistency for the lateral flow application. They are available in standard sizes and specifications listed below.
