I was wondering if there is a type of glass dish with small holes in it to use as a filter. I've found a few but they are either fritted glass disks or a type of funnel.

I was looking for something similar to just a petri dish with no stems or inserts.

  • $\begingroup$ What scale of filtration are you talking about? Do you want to filter tiny crystals of a precipitate from its parent solution, or is this for coarser purposes (like a tea strainer, but glass and flat)? $\endgroup$ Commented Jun 19, 2015 at 3:26
  • $\begingroup$ I was looking for coarser purposes. I have found some vented petri dishes but those seem to only be slits on the side. I was looking for something more like a cocktail strainer where the openings are pin holes and covering the bottom. $\endgroup$ Commented Jun 19, 2015 at 18:02
  • $\begingroup$ Very large (i mean, ~ 0.5-1 l) filtering funnerls with glass filter do exist. Also, see this amazon.com/Kimax-Glass-Crucible-Kimflow-Fritted/dp/B004PLMF7G . There are some types of glassware, using fritted glass disk, but said glassware usually is used for some very specific task. $\endgroup$

The closest I could think of are nozzle cover lids. Wouldn't such tool be ineffective at 'filter'-ing substances nonetheless?

  • $\begingroup$ what kind of nozzle cover lid? Is it glass? $\endgroup$ Commented May 20, 2015 at 0:58
  • $\begingroup$ Most nozzle lids would be plastics or metal as glass would not be useful. However, I'm not sure whether a plastic lid could be transparent. $\endgroup$

  • $\begingroup$ The glass part is more important, not the opacity. I've seen borosilicate crucibles with the fritted glass insert but I was looking for something that I wouldn't have to change the strainer in the bottom. Does something like that really not exist? $\endgroup$ Commented May 20, 2015 at 11:38
