Feedback from one of our customers:

Here are the observations that I made about your columns:

1) Based on the ratio of RNA-to-DNA extraction your columns actually turned out to be somewhat suboptimal, they end up with capturing a bit too much DNA together with the RNA

2) However, the total amount of extracted nucleic acid product is very high. Based on this I am expecting your columns to be optimal for DNA extraction

3) Visually the columns look very nice. I have observed that even when using ThermoFisher Kit columns, I see some settling of the membrane at the end of all steps (that is due to centrifugation the membrane compresses and there is a visible separation between the membrane and the o-ring that holds it in place). However, this effect was almost completely absent from your columns, so the craftmanship and quality of the membrane look very good.
