150 mm ashless and blue ribbon filters (approx. 0.004%) are recommended for quantitative analysis, routine gravimetric tests and sample preparation for instrumental analysis. They are perfectly qualified for food control, beverage analysis and environmental monitoring. are very pure filters suitable for a wide range of critical analytical filtration procedures.

30 x 80 mm high-purity cellulose extraction thimbles are manufactured from pure cellulose that is totally free from binding elements and especially designed for reliable and fast analysis in the areas of food control and environmental monitoring. They are suitable for Soxhlet-type devices to extract certain components out of solid material with an appropriate solvent.

50 ml Titrette® without PC interface can be used to titrate quickly and reliably, even with restricted space and independent of available power connections - in the laboratory, in production, or in the field. This burette guarantees a precise titration within the error limits of Class A.

47 mm highly pure filters (approx. 0.08% ash) are especially recommended for precise identification of materials and for sample preparation prior to sensitive detection methods. They can be used as standard grade filter papers for fine crystalline precipitates. Thanks to their high stability and durability, analysis of soils and fertilizers can be performed easily.

25 mm high-purity glass fiber filters are manufactured from 100% borosilicate glass fibers with inorganic binders and have a good chemical stability. They are recommended for environmental analysis and controlling both air and water pollution, providing high flow speed and high permeability to air.

47 mm high-purity glass fiber filters are manufactured from 100% borosilicate glass fibers without binder and have a high flow speed and high permeability to air. They are recommended for environmental analysis and controlling both air and water pollution. Their large surface area provides an outstanding retention capacity.

33 x 94 mm high-purity cellulose extraction thimbles are manufactured from pure cellulose that is totally free from binding elements and especially designed for reliable and fast analysis in the areas of food control and environmental monitoring. They are suitable for Soxhlet-type devices to extract certain components out of solid material with an appropriate solvent.
