Product Description
Reducing large solvent extracts to a small, analysis-ready volume without losing semi-volatile compounds is exactly what a Kuderna-Danish apparatus was designed to do reliably and repeatably. This complete assembly gives environmental and residue labs a proven way to concentrate extracts before chromatography.
This listing is for Kimble catalog number 570010-0250: KONTES Kuderna-Danish Apparatus, 250 mL. The apparatus combines an evaporator flask, Snyder column and graduated concentrator tube, offered with 250 or 500 mL flasks and 10 or 15 mL tubes. It is made from low-extractable 33 expansion borosilicate glass meeting USP Type I and ASTM E438 Type I, Class A. A 547300 or 547400 solvent recovery apparatus can be added to capture evaporated solvent. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
