A liquid-liquid extractor for use with lighter- or heavier-than-water extracting solvents
When working with solvents lighter than water, the glass dispersion tube adapter is inserted into the extractor body and the #25 Ace-Thred on the body and #7 Ace-Thred near the bottom are plugged. Solvent flask is heated and vapors rise to condenser through glass elbow tube connected by two #25 threads. Condensed solvent fills adapter tube stem and is dispersed upward through sample from capillary on bottom of stem, thereby increasing solvent surface-area-to-volume ratio. Solvent overflows thru PTFE tubing connected to #7 Ace-Thred on body top to flask. (For JUST lighter-than-water applications, order 89056-090, 89056-092, 89056-096, 89056-098, 89056-102, 89055-984, 89052-828, 89052-806 and two 89059-226).
When working with solvents heavier than water, the dispersion tube adapter is removed and the #7 thread near extractor body is plugged. Solvent is heated in flask, vapors rise through glass elbow tube connected to #25 Ace-Thred on flask and extractor body and liquefy in condenser. Solvent droplets pass down through sample and return to flask via PTFE tube connected to #7 Ace-Threds near body bottom and flask. (For JUST heavier-than-water applications, order 89056-090, 89056-094, 89056-100, 89056-102, 89055-984, 89052-828 and two 89059-226).
Overflow and boil-up tube uses Ace-Thred connections, thus allowing easy removal for cleaning to reduce cross-contamination among samples. Joints are standard taper 45/50. Made of borosilicate glass.
