Grade 2 Qualitative Paper 12.5CM 1002-125

• 12.5cm Diameter, Pore Size: 8µm
• Whatman™ Grade 2 Qualitative Filter Paper
• Used in qualitative analytical techniques to determine and identify materials
• General filtration in the 8µm particle size range
• More absorbent than Grade 1; for example - it is able to hold soil nutrient in plant growth trials

This Whatman™ 12.5cm Grade 2 cellulose filter paper is used in qualitative analytical techniques to determine and identify materials.

It is slightly more retentive (8µm) than Whatman™ Grade 1 with a corresponding increase in filtration time (i.e. slightly slower filtration speed). It is also more absorbent than Grade 1.

In addition to general filtration in the 8 µm particle size range the extra absorbency is utilized. For example it holds soil nutrient in plant growth trials.

Additionally it is used for monitoring specific contaminants in the atmosphere and in soil testing. Retention: 8µm. Diameter: 12.5cm.
