Product Description
Purify milligram quantities of solid without losing product on filter paper. The Craig tube lets you dissolve, crystallize and separate crystals from mother liquor in one small vessel, which makes it a favorite for microscale organic labs and precious research samples.
This listing is for Kimble catalog number 283550-0007: KONTES Craig Recrystallization Tube, 100 mm, 7 mL. The tube is made from borosilicate glass 3.3 with a 14 mm OD. A hot filtered solution is allowed to cool inside the tube to induce crystallization, then the assembly is spun in a centrifuge to remove the liquid. Two tubes are needed to balance the centrifuge. This model holds 7 mL and stands 100 mm tall. Order it from LIGHT LABS and keep your lab stocked with genuine DWK Life Sciences products.
