Product Description
Complete your Craig tube recrystallization setup with the plug that does the separating. The plug sits inside the tube so that, when the assembly is inverted and centrifuged, mother liquor flows past while purified crystals are held back for easy recovery.
This listing is for Kimble catalog number 747331-0001: KONTES Glass Plug For 1 and 2mL Craig Tube. Two materials are offered for 1 mL and 2 mL Craig tubes. The glass plug is made from borosilicate glass 3.3, while the PTFE plug offers a chemically inert, non-breakable alternative. Choose the material that best suits your solvents and handling preferences, and keep spares on hand for teaching labs where plugs are easily misplaced. Order it from LIGHT LABS and keep your lab stocked with genuine DWK Life Sciences products.
