Standard Qualitative Filter Papers


Product ID:  304125
Brand: Johnson Test Paper -UK

Standard Qualitative Filter Papers are used for low gravity, or even quadrant-folded application. Standard Filter Papers have a higher level of α- cellulose than other filter papers, this means that it will weaken when the paper has become introduced to water. We do not recommend Standard Filter Papers if wet handling or vacuum work is necessary. In routine quadrant-folded applications the underline strength of standard (untreated) grades does not present an issue.
