Syringe/Disc Filters The smaller conventional Corning® syringe disc-type filters (4, 15, 25, 26, and 28 mm diameter) are used with syringes which serves as both the fluid reservoir and the pressure source. They are 100% integrity tested. The HPLC-certified non-sterile syringe filters are available with nylon, regenerated
Sartorius Gridded Sterile Cellulose Nitrate Membrane Filters, 0.45μm are single-packed membranes with colored grids for colony counting, particle testing and microscopy. The 0.45μm pore size is made in accordance with ISO 7704. Choose from two diameters and quantities in a range of filter/grid color combinations.
Syringe Filters MCE syringe filters are made using high-quality nitrocellulose polymer (cellulose nitrate and cellulose acetate). This material is easily blocked to give it a very.
EZFlow® Syringe Filters. EZFlow 13mm, 25mm, and 33mm Syringe Filters are used for prefiltration, clarification, or fine particulate removal. These syringe filters are available in a variety of filter membrane materials, offered in 0.2µm or 0.45µm pore sizes. The filter membranes are reinforced with polypropylene.

Laboratory filtration products come in many formats and with varying properties and yet the basics of filtration and many of the filter properties do not change. We have compiled these resources to help you select and use our products.
Hydrophobic filters are best suited for gas filtration, low surface tension solvents, and venting. In certain applications, hydrophobic filters are used to filter aqueous solutions because of compatibility requirements. Water or aqueous solutions can also pass through a hydrophobic filter once the water breakthrough pressure is reached.
Nylon Membrane. Nylon membrane filter is a supported, naturally hydrophilic membrane .Nylon membrane filters are flexible, durable and tear resistant, and can be autoclaved at 121 ° C. Application. High strength and heat resistance. Use for HPLC sample preparation,to sterilize biological solutions or buffers,or for vacuum degassing.
previously prepared using 0.22μm sterile syringe filter. Alg/Sr Hydrogel was prepared in two forms - Alg/Sr Beads as well as Alg/Sr Gel for in vitro cytotoxicity and 3D cell culture evaluations (fig 1). Fig 1: Visible Alg/Sr Beads in petri dish. Chemistry of Alginate and Strontium Strontium is available in nature - soil, water, plants and
Jul 02, 2019 · The supernatant was collected, evaporated until near dryness under a nitrogen flow, reconstituted with 0.5 mL of acetonitrile and filtered through a 0.22μm nylon syringe filter. The reconstituted extract was diluted with acetonitrile-water solution (1:9, v / v ) (pH 4.0) to 20 mL as sample solution.
