Winterization

ABOUT WINTERIZATION
  • Winterization is the process of filtering out unwanted waxy plant particles after extraction. The extract and a solution are combined and placed in a freezer overnight. The waxy particles resulting from the freezing procedure are removed using vacuum filtration. This process works best when low temperatures are maintained.
HOW UNITED (PRODUCTS) CAN HELP
  • Large capacity labware enables economical batch runs (Filtering Flasks/Bottles)
  • Porcelain components can withstand temperature changes between a freezer and a laboratory setting (Buchner Funnels)
  • Components are pre-selected for compatibility and offered as kits (Winterization Kits)
WINTERIZATION LABWARE KITS

Each convenient package includes a filtering flask, buchner funnel, filter adapter set, and medium flow filter paper. Filtering flasks are from our FG5340 series. They are constructed using heavy wall borosilicate and include a thick rim and hose barb. The 10,000ml set includes our FFB5340 series heavy wall borosilicate filtering bottle with hose barb. Porcelain buchner funnels are from our JBF series. All kits include our FASN07 filter adapter set. Filter paper is from our FPR series and has medium porosity and flow rate. Circular filters are packaged 100 per box.

FILTER ADAPTER SET OF 7, SYNTHETIC RUBBER

Set of seven synthetic rubber adapter cones 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. Autoclavable.

Filter adapter set is used to make an air-tight seal between a buchner funnel and a filtering flask

WINTERIZATION LABWARE KITS

Porcelain Buchner funnels include fixed perforated plates. Funnels are glazed on inner and outer surfaces except for the rims.

Autoclavable. Withstand temperatures to 1150°C. To prevent thermal stress cracks, we strongly recommend a heating/cooling rate not exceeding 200°C per hour. United porcelain buchner funnels offer excellent resistance to acids and alkalies except for hydrofluoric acid.

Porcelain buchner funnels can be placed in the freezer overnight to help maintain low temperatures during winterization
