…filters are washed three times with deionized water, dried at 105°C, then furnace treated at 550°C to remove any volatile components. They are then weighed to 0.0001g. Each filter is in an individual aluminum pan with the filter weight printed on a Mylar® label affixed to the pan. Filter…

…premium filtration paper that is FDA CFR 21 compliant and has a recall traceability protocol to ensure GMP compliance.  This paper is more expensive than low-quality brands, but the premium is well worth the peace of mind. Paper diameter: 760mm Fits: 800mm Sambo Creeck Filter Trolley

…but gentle sample processing. Material then travels to the collecting vessel enclosing the grinding chamber or to the downstream cyclone or paper filter bag. Maximum feed particle size is 10 mm. Maximum sample volume is 900 mL, up to 5000 mL with cyclone. Fineness is as low as 40 µm, depending…

FDA Food grade cellulose filter paper for laboratory filtration. This is a premium filtration paper that is FDA CFR 21 compliant and has a recall traceability protocol to ensure GMP compliance.  This paper is more expensive than low-quality brands, but the premium is well worth the peace…

Qualitative filter papers: Made of refined pulp and cotton linters with more than 95% alpha cellulose content. The ash content of these filter papers is < 0.1% and they are essentially used for qualitative analysis. Sartorius offers two categories of qualitative filter paper: those that are wet…

Our general-purpose filter papers are available in a variety of diameters. Sold in boxes of 100 pieces of paper. PRODUCT WARNINGS Our products are not toys . Use in a laboratory or educational setting only. Not for children 13 and under.

The LaMotte 11 cm filter paper is mainly used as a semi-permeable barrier to segregate components from air or liquid flow. It is suitable for use in research facilities and chemical laboratories to conduct wide range of experiments.

Characteristics: white, crepe, cellulose with wet strength resin

Advantec Quantitative Ashless Filter Papers are made from the highest quality alpha cotton cellulose. One critical step in the manufacturing process of these filter papers is acid washing. All grades are double acid washed in hydrochloric then hydrofluoric acid to reduce levels of SiO2, CaO, and…

Grade 470 papers are made of cellulose and diatomaceous earth and offer a much better separating capability than pure cellulose papers at the same rate of filtration. This grade quickly retains the finest particles at high flow rates.

Ahlstrom 480 is a hydrophobic silicone-impregnated paper intended for phase separation.

Ahlstrom 615 has a rough surface and is used for filtering aluminum, ferric and magnesium hydroxides. It is also found in general construction filtration work and in the filtration of insoluble iron and ore. Filtration Speed Herzberg sec/100mls: 29 Loading Capacity: High

…with tight matrices for removal of fine precipitates. Ahlstrom-Munksjö's pre-pleated grades can save valuable time and maximize the efficiency of the laboratory filter system. Pleating improves the effective surface area increasing flow rate and loading capacity thus decreasing filtration time.

A deep black, qualitative paper for filtering light colored sediments, etc. Medium speed Retains crystalline precipitates of medium fineness 6 µm pore size

Ahlstrom's qualitative grades of filter paper are, by definition, recommended for use in analytical methods, which determine or identify particulate constituents of a mixture irrespective of the amount present. Qualitative filter papers are often used in routine separation work that still…

Quantitative cellulose filter papers are primarily used in gravimetric analysis procedures and perform separations by entrapping particulate within the random matrix of cellulose fibers within the depth of the media. This media family is also widely used in methods to prepare samples for further…

…filter papers perform separation by entrapping particulate within the random matrix of cellulose fibers within the depth of the media. This media is widely used in methods requiring the determination and identification of particulate in both liquids and gas. Also, this natural fiber filter paper is…

…TCLP Filter This grade has similar performance properties to Grade 151 and is made with acid-treated borosilicate glass microfibers with inherently low levels of barium and zinc. The filter media contains no binders or other additives that may cause interference with samples. The filters resist…

…A filter paper disc, placed in the centrifuge, is used to collect the extract from the sample. The filter disc is then tested. Grade 901 meets the requirements for the filter rings. Method B is done using a reflux extractor. The reflux extractor consists of two cone type screens. The filter paper…
