Cellulose filters made from high quality cotton wadding. Qualitative filters are used in qualitative analysis techniques to determine and identify substances. Some grades are reinforced with a stable resin making them resistant to moisture.
3 grades available:
• standard: Grade 1, Grade 2, Grade 3, Grade 4, Grade 5 and Grade 6;
• wet strengthened: Grade 91, Grade 93, Grade 113 and Grade 114;
• pre-folded: Grade 2V, Grade 113V and Grade 114V.
Characteristics of standard folded qualitative paper:
• Saves time thanks to the folded format: it is not necessary to fold the filters in four;
• Greater filtration surface;
• Maintains the filtration rate of the filter: no premature fouling;
• Folding without affecting the technical characteristics of the filter
