What is the Difference Between Whatman Filter Paper 1 and 2?
🆚 Go to Comparative Table 🆚The main difference between Whatman Filter Paper 1 and 2 is their retention and filtration properties.
- Whatman Filter Paper 1: This is the most widely used filter paper in routine applications requiring medium retention and flow rate. It is used for clarifying liquids and has a particle retention size of 11 micrometers. It is suitable for most filtration applications and is ideal for general-purpose use.
- Whatman Filter Paper 2: This filter paper is slightly more retentive than Grade 1, with an equivalent increase in filtration time. It has a particle retention size of 8 micrometers. Due to its more efficient filtration, the filtration time is higher compared to Grade 1 filter paper. It is commonly used for applications such as analyzing plant growth, monitoring contaminants in air and soil, and filtering fine precipitates.
In summary, Whatman Filter Paper 1 is slightly less retentive than Whatman Filter Paper 2, with Grade 1 being more suitable for general-purpose use and Grade 2 being more suitable for applications requiring finer filtration.
Comparative Table: Whatman Filter Paper 1 vs 2
The main difference between Whatman Filter Paper 1 and 2 is their retention capacity. Here is a table comparing the two:
Property | Whatman Filter Paper 1 | Whatman Filter Paper 2 |
---|---|---|
Retention Capacity (particle size) | 11 µm | 8 µm |
Flow Rate | Medium | Slightly slower than Grade 1 |
Applications | Routine applications requiring medium retention and flow rate, clarifying liquids, soil analysis, and seed testing procedures | Slightly more retentive applications, such as analysis of plant growth and monitoring contaminants in air and soil |
Both Whatman Filter Paper 1 and 2 are qualitative filter papers made from cellulose fiber and are used for general purpose filtration in various industries. Whatman Filter Paper 1 is the most widely used filter paper for routine applications requiring medium retention and flow rate, making it suitable for a wide range of laboratory applications and frequently used for clarifying liquids. On the other hand, Whatman Filter Paper 2 is slightly more retentive than Grade 1 and has an equivalent increase in filtration time, making it suitable for applications that require greater retention capacity.
