Product Description
Swap or replace water fittings without risking the condenser itself. Removable hose connections take the stress off the glass, cutting down on broken barbs, while an internal coil provides the cooling capacity needed for long, vigorous refluxes and solvent-heavy reactions.
This listing is for Kimble catalog number 283100-0000: KONTES Coil-Type Reflux Condenser, With Removable Hose Connections, 205 mm. Each condenser has an internal coil-type cold finger and removable hose connections that fit 4 mm ID tubing. Choose a 205 mm 14/20 model with offset top joint, or 315 mm and 415 mm 24/40 models with jacket lengths of 150 and 250 mm. Glass is low extractable 33 expansion borosilicate meeting USP Type I and ASTM E438. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
