Background, typical uses and selection points for this product. We can send model drawings, technical data and samples to support your evaluation.
The Soxhlet extractor, invented by Franz von Soxhlet in 1879, automates solvent extraction. Solvent boils in a flask below, the vapor rises into a condenser and drips onto a sample held in a thimble; when the chamber fills, a siphon returns the solvent to the flask and the cycle repeats.
Because each cycle uses freshly distilled solvent, the method extracts thoroughly with a modest solvent volume, which is why it remains a reference technique for fat and residue extraction.
Soxhlet apparatus is used for fat and oil extraction and total-fat determination, for extracting pesticides and other residues from soils and foods, for polymer and additive extraction, and for isolating natural products from plant material. Typical buyers are food and feed analysis labs, environmental labs, polymer and materials labs, and university research and teaching groups that run extractions in parallel banks.
A complete set has three parts in borosilicate 3.3: the extractor body with its siphon arm and vapor tube, a condenser on top, and a round-bottom boiling flask below. The parts connect through standard-taper ground joints such as 24/40, 29/32 or 45/40, so components from one joint standard mate together. Condensers come in bulb or coil designs with hose connections for cooling water, and the sample sits in a cellulose or glass-fiber thimble inside the body.
Assemble with matching joints, lightly greased or held with joint clips, and start the cooling water before heating so all solvent vapor condenses. Add anti-bumping granules to the flask and heat gently with a mantle or bath, never an open flame with flammable solvents. Run the apparatus in a fume hood, and let it cool fully before taking it apart.
We form each component in borosilicate 3.3 with its ground joints and anneal it. Siphon geometry is set so the chamber cycles reliably, and joint sizes are checked so parts mate across a set. We supply complete sets or single replacement parts, a choice of condenser type, alternative joint sizes, and thimbles to match. Tell us your extractor size and joint standard and we’ll quote sets or spares.
Customization
We specify the container, closure, decoration and transit packing as one package, so every part fits and arrives ready for your filling line.
Choose from standard sizes or request a custom capacity. We supply drawings with tolerances, label panel dimensions and nominal and brimful capacity.
We match caps, liners, pumps, droppers and stoppers to the neck finish and check the seal against your contents and filling process.
Flint, amber and colored glass, with frosting, spray coating, screen printing, hot stamping or labels. Material documentation is available on request.
Partitioned cartons, layer pads or bulk pallets, with shipping marks and pallet patterns planned for your route and warehouse.
Applications
Typical markets and uses. Tell us your contents, filling process and storage conditions and we will recommend the right model and components.
We confirm availability of the standard model, and review any changes to size, color, decoration or tooling for feasibility and lead time.
We send samples and specification sheets so you can check dimensions, component fit and finish before you place the order.
Your quotation covers packing design, shipping route, Incoterms and export documents, so landed cost is clear from the start.
