When your vacuum filtration operation stalls, it is normally due to filter loading. All of the small pores have been clogged and no more fluid can pass no matter how high the vacuum pressure in the flask.
This prefilter basket strainer fits in your funnel. You pour the liquid through it to filter out the larger particles to keep them out of the fine filter.
A great tool for infusions to filter out your larger ingredients.
Fits all Filtr8 Funnels, both sand core and Buchner.
Only includes the strainer. Flask and funnel are just to show product in use.
