Glass fibre filters


Where can I find glass fibre filters? Are they under another name or product that I can look for in the local hardware? I'd like to use them for DPPP ect. filtering.

Isn't common household isulation made of glass fibers? Or am I mistaken?

I was thinking of using it to filter concentrated acids, but the need never came up and I forgot about it.

Some furnace filters are nearly all fiber glass. And some insulations contain a large protion of fiber glass, I read somewhere (but maybe just planned) that boiling insulation with HCl makes it good enough for filtering and other applications in chemistry.

Glass fibre filters are only for reactions
when filtered out precipitations which prepared by strong acids [concentrated H2SO4 ...].

Hard to get, only in specialising chem. stores.
Metal strainers wich laminated with nickel or chrom are soever useful.

the best filter cloth is polypropelyne fiber filters, it is cheap, good against any acid, base and organic solvents. The only bad thing is you cant do higher temperature filtration with it (above 70C). The glass filter paper is usually finer .3micron and costs more.

Dear Mickhael, you can find filter material in nearly all auto-repaire shops. They use this glass fiber cloth in combination with polyester resin to repaire car body damage. They sell this glass fiber cloth sometimes only in kits, or as lose sepperate cloth. Make shoure that it is 100% glass fiber before you buy it. It should look shiny semitransparrent white. All you have to do, is to cut out a piece and line your filter with it as single or multi layer. Use sisors to cut it that may become blunt, and be carefull when handeling it, don't get spliters on your hands and in your eyes.

Just as Chris the Great said, common household insulation has a large precentage of fiber glass. During my experimentation with ferrates and chromium trioxide I used insulaiton extensively for my filtrations, taking a ball of it and shoving it into the neck of a funnel for a simple method of filtration. Strong oxidizing agents turn the yellow coloration of the insulaiton I bought white and make it look just like the glass wool I get in the chem labs at school. Pre-treating it with oxidizing agents may show positive results in giving a fairly consistent glass wool product from OTC sources.

Lambda has a good point in that muffler kits contain sheets of woven fiber glass sometimes also there are stores that carry materials for fiber glass where sheets may be purchased directly.
