General description
Grade 201 is a thin retentive paper, smooth surfaced with close texture. It is excellent for general purpose use where retention of medium-fine precipitates is needed and relatively low filtration speed is unimportant: a particularly useful student grade. The paper structure is designed for retentivity and thus filtration speed and loading capacity are comparatively low.
Note: These papers should not be used for kjeldahl nitrogen anaylsis.
Features and Benefits
- Retains medium-fine precipitates
- Relatively slow filtration speed
- Smooth surface and close texture
- For general-purpose qualitative analysis
