Filter Papers, Grade 1
GRADE 1: Suitable for medium retention & flow rate applications. Grade 1 is the standard filter paper and is mostly used filter paper for routine applications in the laboratory. This grade is widely used for clarifying liquids and in qualitative analytical separations for precipitates such as lead sulfate, calcium oxalate & calcium carbonate.
General Properties of Grade 1 are:
1. Particle Retention Liquid – 9 µm,
2. Initial Filtration Speed -155 secs/100 ml,
3. Thickness – 0.20 mm,
4. Weight – 87 g/m2,
5. Dry Bursting Strength – 89 KPa.SKU: FP-001 - Uncategorized
Filter Papers, Grade 2
GRADE 2: Grade 2 filter paper is little more retentive & having more absorbing power than Grade 1 filter paper with a corresponding increase in filtration time.
General Properties of Grade 2 are:
1. Particle Retention Liquid – 9 µm,
2. Initial Filtration Speed -250 secs/100 ml,
3. Thickness – 0.21 mm,
4. Weight – 98 g/m2,
5. Dry Bursting Strength – 108 KPa.SKU: FP-002 - Uncategorized
Filter Papers, Grade 3
GRADE 3: Grade 3 filter paper is almost double to filter paper Grade 1 with a still finer particle retention and excellent loading capacity. The extra thickness gives more increasing wet strength.
General Properties of Grade 3 are:
1. Particle Retention Liquid – 5 µm,
2. Initial Filtration Speed -325 secs/100 ml,
3. Thickness – 0.40 mm,
4. Weight – 180 g/m2,
5. Dry Bursting Strength – 187 KPa.SKU: FP-003
