Description by Type Evaporation by Kuderna-Danish A high speed evaporation glassware system designed to rapidly reduce large solvent volumes to endpoints of 110 ML. Glassware features solvent recovery and 3-ball Snyder column to remove micro droplet presence in the vapor stream. Very effective in retaining semivolitile presence in the concentrate.
Evaporation by traditional glassware Similar to KID evaporation but uses flat bottom flasks and is designed to go to dryness. A gas injector can be used to automate this procedure. Solvent recovery is standard, Snyder column is optional. Meets a variety of procedures including US EPA Oil & Grease methods (1664).
Extraction by Solid / Liquid Soxhlet & evaporative Soxhlet An effective method for removing organic materials from solid materials by continually immersing and removing the solid in an organic solvent. Through clever glassware design, the chamber containing the solid material is repeatedly flooded and drained until all trace organic materials are removed, without moving parts. A variant of this design allows a follow up evaporation to occur by opening a valve, without removing the glassware from the heating system.
Extraction by Liquid / Liquid A procedure to remove trace organic materials from 1 liter water samples by continually dripping an immissable distilled solvent repeatedly through the sample water column until extracted to exhaustion. Variants of these designs include high accuracy extractors and extractors with evaporative capabilities. For evaporative design see ROT-X-TRACT-LC using an accelerated extractor. |
