I was sent an opened package that was definitely a returned, and I was charged for a brand new box. Very, very disappointed in this vendor

These work perfectly for my geology lab to chemically extract copper from malachite. Thank you! Please keep these available for future purchases!

I brought these to test the FE of a waste water treatment plant.I needed them quickly as our usual suppliers were out of stock of the ones we use normally.These are a little difficult to work with but the product itself is OK a little cheap feeling but saved our bacon for a few days.

"Quantitative Filter Papers/ Hardened Filter Papers are used for quantitative and gravimetric analyses where the precipitate is to be recovered, as well as for pressure or vacuum filtration. Qualitative Filter Papers are used for qualitative analytical techniques to separate, determine and identify materials."Also pay attention to particle size.Other than that. They work as they should. Bang for buck purchase.

The filters do exactly what they're intended to do, but due to the slow flow rate I can't imagine using gravity filtration exclusively, use a vaccume apparatus.Ps: stonylabs, make the same filters but with a smaller pore size I would love you.
