Please be aware that we only have filter papers with a micron rating of 20 at this time. I appreciate the kind words, Lizzy L.
Thank you for purchasing this item. However, it is only intended to be used in laboratories. Lizzy L. thanks for your comment.
Considering that filtering will be done below freezing for my purposes, it wouldn't be much help to answer your question about the range of working temperatures. Although there is no indication on the packaging, it seems like a good filter
Selected User Reviews For StonyLab Qualitative Filter Paper Circles, 125mm Diameter Cellulose Filter Paper with 20 Micron Particle Retention Medium Filtration Speed, Pack of 100 (125mm Diameter)
During a filtration where it wasn't exposed to harsh chemicals, not too alkaline or acidic, etc. , the first filter disintegrated completely. That makes me nervous about using the rest of the 99 filters.
This product does not work for me, the filters are too thick for my oils I made my own filters from cheap coffee filters instead.
On adding pH 10 to the paste, it dissolves instantly. An email to the company seeking guidance on an alternative product was never returned.
The quality of the filter paper felt good and it met its purpose of filtering an oily.
I'm very happy with it.
I have had no problems after using it a few times. Delivery was prompt, the product worked well. I am satisfied with this.
Then you do not fit in. This is a very poor description. It is difficult to determine the filtration sizes as well.
I use it with a vacuum quite well.
