Whatman

• Grade 520 a ½: 15-18 µm

• A thin paper with great wet strength and a very high flow rate

• Frequently used in technical applications such as the filtration of viscous liquids and emulsions (e.g., sweetened juices, spirits and syrup

• Acid-washed paper with ash content of approximately 0.01%, low magnesium, for the determination of trace elements (Mg, Mn, Co, Cu, Mo, B)

• Grade 1: 11 µm

• The most widely used filter paper for routine applications with medium retention and flow rate

• In agriculture, it is used for soil analysis and seed testing procedures

• In the food industry, Grade 1 is use

• Thick filter with fine particle filter and good loading capacity

• Particularly useful for liquid clarification and liquid scintillation counting

• Application: Used in LSC techniques where high loading capacity is required

&bu

• Grade 602 h: < 2 µm

• A dense filter paper for collecting very small particles and removing fine precipitates

• Used in sample preparation (e.g., in the beverage industry for residual sugar determination, acidic spectra, refractome

• Grade 6: 3 µm

• Twice as fast as Grade 5 with similar fine particle retention

• Often specified for boiler water analysis applications

• Grade 2589 a: 6-12 µm

• A fast to medium fast filter with high wet strength offering medium retention

• Grade 597: 4-7 µm

• A medium fast filter paper with medium to fine particle retention

• Used for a wide variety of analytical routine applications in different industries like food testing (e.g., determination of fat content) or re

• Grade 4: 20-25 µm

• Extremely fast filtering with excellent retention of coarse particles and gelatinous precipitates such as ferric hydroxide and aluminum hydroxide

• Very useful as a rapid filter for routine clean-up of biologica

• Grade 520 a ½: 15-18 µm

• A thin paper with great wet strength and a very high flow rate

• Frequently used in technical applications such as the filtration of viscous liquids and emulsions (e.g., sweetened juices, spirits and syrup

• Acid-washed paper with ash content of approximately 0.01%, low magnesium, for the determination of trace elements (Mg, Mn, Co, Cu, Mo, B)

• Grade 2: 8 µm

• Slightly more retentive than Grade 1 with a corresponding increase in filtration time (ie. slightly slower filtration speed)

• More absorbent than Grade 1

• Thick filter with fine particle filter and good loading capacity

• Particularly useful for liquid clarification and liquid scintillation counting

• Application: Used in LSC techniques where high loading capacity is required
