About this item

  • Type: Fast Speed Qualitative Filter Paper, ideal for retaining crystalline materials and for general chemistry applications.
  • Diameter: 7cm, Bore Diameter: 20-25um, Filtration Rate: Less than 35s, Ash Content: Less than or equal to 0.15%, Quantitate: 80 +/- 4 g/m2
  • Loose paper, strong absorbance to liquids. It is a filter paper commonly used in chemical laboratories for the filtration of sediments and suspended solids. Its ash content is higher than quantitative filter paper, and it has a certain amount of ash after burning.
  • Non-Toxic and Tasteless: Without any additives, chemical stability. Non-toxic and tasteless, acid and alkali, through the hot-rolled filtration accuracy of up to 0.1 microns.
  • Qualtitative filter paper usually residue more ash, its usually use for general qualitative analysis and precipitation or suspension of solution, it can't be used for quality analysis.

I had ordered the incorrect filters but I made them work. Seemed fine but I don’t have many other brands to compare with so I’m not so sure my opinion on these is of value. The ordering and delivery process was easy and had no issues everything went smoothly.

It's possible that this performs the actual filtration decently, but the paper disintegrates when I try to remove it from the funnel/filter holder.
