Product Description
Getting to an exact final extract volume is easier when the receiving tube is graduated in fine increments. This Kuderna-Danish apparatus pairs a proven evaporative concentrator with a 10 mL graduated tube, letting analysts concentrate samples and read the endpoint without transferring to another vessel.
This listing is for Kimble catalog number 570025-0500: KONTES Kuderna-Danish Apparatus, 500 mL, Hooks and springs. The concentrator tube is graduated 0-1 mL in 0.1 mL and 2-10 mL in 1 mL. Choose the 570025 series with hooks and springs or the 570035 series with a polyacetal clamp, each with a 250 or 500 mL flask. All glass is low-extractable 33 expansion borosilicate meeting USP Type I and ASTM E438 Type I, Class A. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
