Solid Liquid Extraction Unit Manufacturer,Supplier and Exporter in India
Product Code : EL-TWL-9115
Jlab Export is a leading Solid Liquid Extraction Unit Manufacturer,and suppliers in India
This semi-batch leaching unit works like a large Soxhlet. Solvent boils in a spherical vessel, condenses and runs into the extraction vessel. There it soaks through a glass fibre bag of solids and drains back to be boiled again. The cycle repeats until extraction is complete, and the solvent temperature can be set so students can see its effect on the separation.

Practicals in Solid-Liquid Extraction
A common practical extracts oil from crushed seeds. Students dry and weigh the charge, extract it for a set number of cycles, then dry the spent solids in a Hot Air Oven and weigh them again. The loss in weight gives the percent extracted. Seeds split into size fractions with Test Sieves show how particle size changes the rate.
Repeat runs at two or three solvent temperatures show how much a hotter solvent speeds the extraction. A small portion of the same seed can be run in a Soxhlet Extraction Unit as a check on the yield. Solvent left in a small extract is taken off in a Rotary Vacuum Evaporator, while the unit itself evaporates the main solution to give the extract.
Frequently Asked Questions
How does this unit differ from the rotary-cell extractor?
This unit is semi-batch: one charge of solids sits in a bag while the solvent cycles through it. The Solid-Liquid Extraction Unit with a feed screw and a rotating vessel of extraction cells runs continuously in one, two or three stages.
What does counter-current extraction mean?
Fresh solvent meets the solids that are nearly spent, while the richest solution meets fresh solids. The concentration difference that drives the transfer then stays large along the whole path, so less solvent recovers more of the soluble part than in a single contact.
Why is the solid held in a glass fibre bag?
The bag keeps the solids in the extraction vessel while the solution drains through, so fines are not carried back into the boiling vessel. The spent charge also lifts out in one piece for drying and weighing.
Can the solvent be fed from the top or the bottom?
Yes. The unit can be supplied with the solvent fed from the top, from the bottom, or with a common arrangement for both. Downward feed drains freely through the bag, while upward feed floods the bed and wets all of it.
