Berikut penjelasan lengkapnya :

Paper Grade	Available Sizes	Properties	Applications
Filter Paper Grade 1	Circles: 10 mm to 150 cm (available prepleated) Sheets: 26 x 31 mm to 600 x 600 mm	Particle retention¹: 11µm Nominal thickness: 180 µm Nominal basis weight: 87 g/m² Nominal ash content²: 0.06%	Grade 1 is the most widely used filter paper in routine applications requiring medium retention and flow rate, and is most frequently used for clarifying liquids. Specific applications include: Qualitative analytical separation for lead sulfate, calcium oxalate, and calcium carbonate Soil analysis and seed testing Separating foodstuffs from associated liquid or extracting liquid Collecting atmospheric dust for photometric measurement Gas detection through the addition of a chromogenic reagent
Filter Paper Grade 2	Circles: 42.5 mm to 500 mm (available prepleated) Sheets: 460 x 570 mm to 580 x 680 mm	Particle retention¹: 8µm Nominal thickness: 190 µm Nominal basis weight: 97 g/m² Nominal ash content²: 0.06%	Grade 2 is slightly more retentive than Grade 1, with an equivalent increase in filtration time. Specific applications include: Plant growth trials, where the extra absorbency is utilized to hold soil nutrient Contaminant monitoring in air and soil
Filter Paper Grade 3	Circles: 23 mm to 320 mm (available prepleated) Sheets: 26 x 31 mm to 600 x 600 mm	Particle retention¹: 6µm Nominal thickness: 390 µm Nominal basis weight: 185 g/m² Nominal ash content²: 0.06%	Grade 3 is double the thickness of Grade 1, so it can hold more precipitate without clogging and has increased wet strength. It is designed for use in Büchner funnels, and the high absorbency makes Grade 3 well suited for sample transport after collection.
Filter Paper Grade 4	Circles: 27 mm to 400 mm (available prepleated) Sheets: 38 x 114 mm to 580 x 580 mm	Particle retention¹: 25µm Nominal thickness: 210 µm Nominal basis weight: 92 g/m² Nominal ash content²: 0.06%	Grade 4 is a fast filter material that is well suited for retention of coarse particles and gelatinous precipitates, such as ferric hydroxide and aluminum hydroxide. Specific applications include: Air pollution monitoring where the collection of fine particles is not critical Routine clean-up of biological fluids or organic extracts
Filter Paper Grade 5	Circles: 25 mm to 320 mm (available prepleated)	Particle retention¹: 2.5µm Nominal thickness: 200 µm Nominal basis weight: 100 g/m² Nominal ash content²: 0.06%	Grade 5 provides the maximum degree of fine particle retention in the qualitative paper range, with an equivalent slow flow rate. Specific applications include: Retaining fine precipitates in chemical analysis Clarifying cloudy suspensions in soil and water analysis
Filter Paper Grade 6	Circles: 42.5 mm to 240 mm (available prepleated)	Particle retention¹: 3µm Nominal thickness: 180 µm Nominal basis weight: 100 g/m² Nominal ash content²: 0.06%	Thick with a high loading capacity, Grade 6 provides similar particle retention to Grade 5 with twice the flow rate. It has high absorbency and increased wet strength, and is often specified for boiler water analysis. Plant growth trials, where the extra absorbency is utilized to hold soil nutrient Contaminant monitoring in air and soil
Filter Paper Grade 591	Sheet: 580 x 580mm	Particle retention¹: 12µm Typical thickness: 180 µm Basis weight: 161 g/m² Nominal ash content²: 0.06%	A thick filter paper with very high loading capacity for fast filtration of medium to coarse precipitates. Offers high absorbency and increased wet strength. Also available prepleated as Grade 591 ½.
Filter Paper Grade 595	Circles: 110 mm to 150 mm (available prepleated) Sheet: 580 x 580mm	Particle retention¹: 7µm Typical thickness: 180 µm Basis weight: 68 g/m² Alpha cellulose: 98% minimum	Popular thin filter papers, Grade 595 provides medium-fast flow rate and fine particle retention. It is used in a variety of routine analytical applications, including: Particle separation from food extracts Filtration of solids from digested environmental samples for iCP/AAs analysis
Filter Paper Grade 597	Circles: 12.7 mm to 320 mm (available prepleated)	Particle retention¹: 4-7µm Typical thickness: 180 µm Basis weight: 85 g/m² Alpha cellulose: 98% minimum	A medium-fast flow rate paper with medium-to-fine particle retention, Grade 597 is used in a variety of routine analytical applications, including: Determination of fat content in food testing Removal of carbon dioxide and turbidity from beer and other beverages
Filter Paper Grade 597L	Circles: 40mm x 100mm	Particle retention¹: 7µm Typical thickness: 180 µm Basis weight: 82 g/m²	A qualitative filter paper with low fat content. Suitable for nitrate determination in foodstuffs to §35 LMBG* (* LMBG = German law for food and consumer products). Particle separation from food extracts Filtration of solids from digested environmental samples for iCP/AAs analysis
Filter Paper Grade 598	Circles: 90 mm (available prepleated) Sheet: 580 x 580mm	Particle retention¹: 8-10µm Typical thickness: 320 µm Basis weight: 140 g/m²	A medium-fast to fast flow rate paper with medium particle retention, Grade 598 has a high thickness, giving it a high loading capacity. Particle separation from food extracts Filtration of solids from digested environmental samples for iCP/AAs analysis
Filter Paper Grade 602h	Circles: 125 mm to 240 mm (available prepleated)	Particle retention¹: <2µm Typical thickness: 160 µm Basis weight: 84 g/m²	Grade 602 h is a dense filter designed for collecting very fine particles. It is commonly used in the beverage industry for: Residual sugar determination Acidic spectra Refractometric analysis HPLC
