Quick question to the experienced members with filtering AR solution.
I have a porcelain Buchner funnel/filter which is fine for my silver cement clean up, I only use gravity filtration before cementing out as the cement is destined for further processing eg shot/cell. From my research though polishing of pregnant AR is a different matter as it is directly related to the purity in the end precipitate, not that silver purity is not important or related to filtration, just that the process for my end product is completely different.
I am looking for advice or some general input from experienced members on filtration apparatus setup for polishing AR-Chloroauric pregnant solution, specifically the pro's and con's of using a porcelain Buchner funnel/filter for AR or using a fritted glass setup like lazersteve in his dvd. The fritted glass type I have absolutely zero experience with.
The porcelain type, regarding filtering a solution for the purposes of polishing pregnant AR before precip stage:
Does the lack of precipitate/weight cause issue with filtration even with vacuum, eg wicking/ seeping behind the filter paper necessitating multiple filtrations process?
Anyone with any recommendation toward a specific type of filter for AR polishing??
Do I need to invest in a glass frit type split cylinder?
