Liquid-Liquid Extraction Unit Manufacturer,Supplier and Exporter in India
Product Code : EL-MLE-13261
Jlab Export is a leading Liquid-Liquid Extraction Unit Manufacturer,and suppliers in India
Liquid-Liquid Extraction Unit (code EL-MLE-13261) is a wheeled teaching unit for continuous counter-current solvent extraction in a 55 mm borosilicate glass column packed with Raschig rings. Solvent and feed meet in the packing and leave as separate extract and raffinate streams, with the flows metered by rotameters. The extraction unit and its stainless steel tanks are made by JLab in Ambala, India.

How Extract and Raffinate Form
In liquid–liquid extraction a solvent that does not mix with the feed liquid picks up the solute from it. One liquid fills the column as the continuous phase, the other passes through it as drops (the dispersed phase), and the Raschig rings keep breaking and re-forming those drops so the contact area stays large. The solvent leaves loaded with solute as the extract; the feed, stripped of solute, leaves as the raffinate. Running the two phases counter-current keeps a concentration difference along the whole 750 mm of packing.
The Rest of the Rig
The continuous and dispersed phases are drawn from separate containers and metered before they enter the column. Feed is circulated by compressed air, set on a 0–2 kg/cm² pressure regulator and read on a Bourdon gauge, and transparent elements give a clear view of the process. The same frame carries a distillation column packed with Raschig rings, the unit has controlled electrical bottom heating, and it runs as a continuous or a batch process.
