Question/Answer

Does the cap for the sample container also fit the funnel?

It does not. The funnel does not have screw threads and is not intended to be capped on this product.

Are these trace metal free? Do you test for trace metals?

This filter is not trace metal free. It is a glass fiber filter and will contain high background levels of many metals. We do have another option available that may work better for you, FF100045E. This does not come with any type of certification, but we can send a sample if you wish to test it for suitability.
