Whatman Grade 2 Qualitative Filter Paper, 18.5 cm
Product Code: 1002-185 Pack Size: 100 circles/box
Product Overview
Whatman Grade 2 filter paper is a standard-grade paper designed for a variety of laboratory applications. It offers slightly higher retention and absorbency than Grade 1, making it a versatile choice for routine filtrations and sample analysis.
Key Features and Benefits
- Higher Retention: With a nominal particle retention of 8 µm, Grade 2 is more retentive than Grade 1, allowing for the capture of finer precipitates.
- Increased Filtration Time: The filtration speed is slightly slower than Grade 1 (Herzberg filtration speed of 305 s), corresponding to its finer particle retention capabilities.
- High Absorbency: Its enhanced absorbency is ideal for applications where this property is crucial, such as holding soil nutrients in plant growth trials or for specific analytical procedures.
- Versatile Applications: Commonly used for monitoring specific contaminants in the atmosphere, soil testing, and general laboratory filtrations where finer retention is needed.
