• Contains essential components in convenient package
• High quality 3.3 Borosilicate used for all glass parts
• Flasks and bottles with thick heavy wall construction
• Two sizes offered, 5000 and 10000 ml

Each kit package includes a filtering flask, Buchner funnel, filter adapter set, and medium flow filter paper. Filtering flasks are constructed using heavy wall borosilicate glass and include a thick rim and hose barb. The largest kit includes a strongly constructed vacuum tolerant borosilicate glass 10 L filtering bottle.

All kits include a filter adapter set. The set of seven synthetic rubber adapter cones are designed to fit Buchner and fritted glass funnels, porcelain filters without headpieces, and for reverse flow cleaning of filter crucibles. Adapters can be used to support funnels, Gooch crucibles, filter tubes, and other apparatus in filtration assemblies.

These adapters are functional even if not tightly fitted around the funnel stem. Can be used individually or nested with adjacent sizes. Provide an excellent alternative to boring special size holes in rubber stoppers, and they are autoclavable.

Circular filter paper has medium porosity and flow rate, packaged 100 per box.
