Pros & Cons
👍 Pros
- Contains a very low 0.007 percent maximum ash content, ensuring high purity for sensitive applications.
- Offers a medium nominal particle retention rating of 8 µm, suitable for a range of particulate separations.
- Features a medium filtration speed of Herzberg 340 s, providing a balanced flow rate for laboratory tasks.
- Particularly useful for gravimetric analysis, indicating its precision and reliability in quantitative measurements.
- Comes in a convenient 100-pack, providing an ample supply for ongoing laboratory work.
👎 Cons
- The medium nominal particle retention of 8 µm may not be fine enough for applications requiring sub-micron filtration.
- The medium filtration speed might not be optimal for processes requiring either very rapid or extremely slow filtration.
- Specific dimensions (e.g., diameter) of the filter paper are not provided, which is crucial for compatibility with lab equipment.
- While useful for gravimetric analysis, its suitability for other specialized filtration methods is not specified.
- The ash content, while low, is not zero, which could be a consideration for ultra-trace analysis requiring absolutely no residue.
