Efficient Filtration for Your Lab

This filter paper is top-notch for its qualitative grade and its ability to effectively filter impurities. The absorbent material is well suited for industrial and scientific grade filtration and performs reliably with minimal chances of failure. The only downside I found is that the product's availability can be limited in certain areas. Despite this, I would highly recommend this product for anyone looking for efficient filtration options for any laboratory or scientific application.

Pros
  • Efficiently separates solid particles from liquids
Cons
  • Not suitable for fine particle filtration

maybe too strong?

These papers are well made, not flexible or stuffed into an undersized box. These are NOT quick documents. My primary filtration has gone from 30 minutes to over 2 hours (8 liters). I'd say they're in the mid to slow range, not fast

Pros
  • HIGH FLOW COLLECTION - Picks up large particles in fast moving air or fumes
Cons
  • Quick Guide

Ideal replacement for Melita No. 1 disc filter, Krupps Moka Brewery

blue/white packaging). ) as a filter replacement in my old Krupps Moka Sud…. They worked but the flow rate was half that of the discontinued Melita No 1 disc filters and I was afraid of damaging the coffee maker over time because it filters coffee under pressure. Perfect! Almost the same speed as the discontinued Melita filter! Thanks very much!

Pros
  • Class 4: 18.5cm - Equivalent to Whatman Class 4 quality, standard laboratory filter paper (185mm)
Cons
  • not reliable
