FF170HP Din A4,10/pk A backed and highly consistent membrane for use with low viscosity samples in a lateral flow assay. Exceptional intra- and inter-lot consistency as demonstrated by a coefficient of variation (CV) for capillary rise of <lt/> 10%. Improved assay consistency and reproducible limit of detection. Reduced assay optimization costs, compared to a less consistent membrane. FF High Performance (HP) membranes are part of the AE family, which are directly cast onto a plastic film. The FFHP membranes are a result of improved membrane casting procedures, which result in enhanced intra- and inter lot consistency and sharper lines. The surface is uniform without unincorporated nitrocellulose powder and the fine structure fiber distribution provides large internal surfaces for binding proteins FFHP Membranes Nitrocellulose membranes are a key functional part of lateral-flow assays. The membrane must provide sufficient protein binding to enable the formation of a sharp and intense capture line, but at the same time the level of nonspecific background must be low for easy interpretation of results. Nitrocellulose membranes are available in a range of wicking rates and formulations. It has long been known that the wicking rate of a membrane has a significant impact on test sensitivity.
Grade QM-A Quartz Filter Grade QM-A High-purity quartz (SiO₂) microfiber filters are used for air sampling in acidic gases, stacks, flues and aerosols, particularly at high temperatures up to 500° C and in PM-10 testing. Because of the low level of alkaline earth metals, "artifact" products of sulfates and nitrates (from SO₂ and NO₂) are virtually eliminated. QM-A, sequentially numbered according to EPA standards, is suitable for most applications.

UniPrep Syringeless Filter UniPrep filter vials are preassembled filtration devices for the filtration and storage of laboratory samples. These devices are quick and easy to use and feature a plunger, filter, and vial in one unit. They replace syringe-coupled filtration devices with single, disposable units. The UniPrep devices consist of two parts: a test tube and a filter-plunger. The design incorporates a prefilter and a membrane into the tip of the plunger. When the filter-plunger is pressed through the liquid placed in the test tube, positive pressure forces the filtrate up into the reservoir of the filter-plunger. The UniPrep devices function in a similar way to the Mini-UniPrep. However, UniPrep does not contain a septum in the cap and can be used to filter larger volumes (1 to 5 mL)

Grade 3621 blotter, light blue in color for seed testing applications, 1000/pk Seed testing papers are made from pure cellulose without any additives and do not contain any substances which could influence the growth of the seeds. The constant water absorption of the papers ensures the continuous provision of the required amount of water. The contrast of the color seed testing papers makes evaluation easier, particularly for seeds with fine white rootlets or under artificial light. This makes work easier, improves the results, and saves time. The dyes used have been thoroughly investigated and have no influence on the growth of the seeds.
