I had my chemistry use this filter paper to collect the precipitate from a double displacement reaction, and the results were great. I had tried coffee filters in the past with less than acceptable results. Since I buy the filter paper myself, I did not want to go Whatman.

After working in a hospital laboratory for 46+ years, I was hesitant to order an unknown product. However, the filter paper is working perfectly, with just the right flow rate for filtering dyes.

Low price and high quality. (1/3 the price of the Watman filters)I'd buy more, but they are currently out of stock
