Designed for analysis of non-filterable residue and materials that require a high loading capacity glass microfiber filter. Whatman™ Binder-Free Glass Microfiber Filters, Grade 934-AH Circles are also used in cell harvesting, liquid scintillation, and monitoring pollution.
Covers a wide range of laboratory applications and is frequently used for clarifying liquids. Whatman™ Qualitative Filter Paper: Grade 1 Circles are widely used standard grade filter papers for routine applications with medium retention and flow rates.
Provides an extremely clear and accurate visual pH value using four different segments of dye-impregnated indicator papers. Whatman™ pH Indicator Papers, CF Strips use dyes that are chemically bonded to the paper and cannot be leached into solution.
Strengthened glass filter media by dual lamination with a tough polyester monofilament. Whatman™ HEPA-Vent Filters are ideal for air and gas filtration applications where high retention, dirt-holding capacity and flow rates are required.
Manufactured from high-quality alpha cellulose cotton linter for high-performance use in automated Soxhlet extractor systems. Whatman™ Cellulose Soxhlet Extraction Thimbles are intended for applications including use in air and waste gas analysis.
Combines high loading capacity with fine particle retention. Whatman™ Binder-Free Glass Microfiber Filters, Grade GF/A are ideal for gravimetric determination of airborne particulates, stack sampling and absorption methods of air pollution monitoring.
Filters and retains course particles for monitoring air pollution. Whatman™ Qualitative Filter Paper: Grade 4 Circles are used when high flow rates in air pollution monitoring are required and the collection of fine particles is not critical.
Recognized standard in laboratories worldwide for isolation of human lymphocytes from peripheral blood. GE Healthcare™ Ficoll-Paque™ PLUS Media maintains the viability and a representative distribution of B and T lymphocytes.
Served as the basis filter for EPA standard for the toxicity characteristic leaching procedure. Whatman™ Binder-Free Glass Microfiber Filters GF/F Circles offers an extremely high loading capacity and flow rate.
Supports accurate analysis in applications sensitive to very low levels of background contamination. Whatman™ Quantitative Filter Paper: Grade 40 Circles are additionally useful in gravimetric analysis where ash content might affect weight measurements of combusted samples.
For separation of cells, subcellular particles, and larger viruses (down to approx. 70S) under gentle conditions that preserve viability and morphological integrity. GE Healthcare™ Percoll™ Centrifugation Media Percoll is composed of colloidal silica coated with polyvinylpyrrolidone (PVP).
Combines fine particle retention with good flow rate. Whatman™ Binder-Free Glass Microfiber Filters, Grade GF/C are ideal for the collection of suspended solids in potable water, natural and industrial wastes.
Use for quantitative air pollution analysis as a paper tape for impregnation when determining gaseous compounds at high flow rates or for quantitative air pollution analysis. Whatman™ Quantitative Filter Paper: Grade 41 Circles are commonly used in preparing samples for metal analysis after nitric acid digestion.
Retains the fine precipitates encountered in chemical analysis. Whatman™ Qualitative Filter Paper - Grade 5 Circles are excellent clarifying filters for cloudy suspensions and for water and soil analysis.
Enables the use of highly diluted primary and secondary antibodies without reducing sensitivity. GE Healthcare Lifescience™ Amersham™ ECL™ Prime Western Blotting Detection Reagent produces high signal intensity and sensitivity.
Helps to confine and isolate infectious materials in vacuum systems and protect the laboratory. Whatman™ Vacu-Guard Filter protects vacuum pump systems from solvent vapor or gaseous contaminants and aqueous aerosols.
Creates a hydrophobic filter that can replace separatory funnel in some applications. Whatman™ 1PS Disposable Phase Separating Paper is impregnated with stable silicone to allow solvent phases to pass through while retaining aqueous phases.
