• Grade 5: 2.5 µm

• Capable of retaining the fine precipitates encountered in chemical analysis

• Slow flow rate

• Excellent clarifying filter for cloudy suspensions and for water and soil analysis

• Grade 2294: 8-15 µm

• A very thick filter card with high wet strength

• Offers very high flow rate and retains medium to coarse particles

• Grade 595: 4-7 µm

• Very popular, thin filter paper, medium-fast with medium to fine particle retention

• Used for many routine analytical applications in different industries, (e.g., particle separation from food extracts or filtr

• Grade 3: 6 µm

• Double the thickness of Grade 1 with still finer particle retention and excellent loading capacity; more precipitate can be held without clogging

• The extra thickness gives increased wet strength and makes this gra

• Grade 589/3: 2 µm

• Ashless (ash 0.01%) standard filter paper for very fine precipitates (class 2d acc. to DIN 53 135)

• Slow filter paper with highest efficiency for collecting very small particles

• Also used for many ro

• 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
