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 747331-0631: KONTES PTFE Plug. 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. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
