Product Description
Recrystallize milligram quantities of solid and separate the crystals from the mother liquor without a filter paper transfer. Craig tubes let you dissolve, cool and then centrifuge in one vessel, which dramatically improves recovery compared with filtering tiny amounts of product.
This listing is for Kimble catalog number 747330-0003: KONTES Craig Recrystallization Tube, 2 mL. The tube is made from borosilicate glass 3.3 and is an accessory for microscale Standard Taper 14/10 threaded kits. It works with a matching plug: the solution is crystallized in the tube, the plug is inserted, and the assembly is inverted and spun so liquid passes around the plug while crystals stay behind. Sold in sets. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
