Soxhlet stillheads supplied by LabChoice Australia are engineered to deliver stable, efficient solvent cycling during continuous extraction procedures. Manufactured from high quality BORO 3.3 borosilicate glass that complies with ISO 3585 and ASTM E438 Type 1 Class A standards, each stillhead provides strong thermal resistance, excellent chemical durability and precise dimensional accuracy. These properties ensure reliable operation during repeated heating and cooling cycles, which is essential for Soxhlet extraction workflows involving organic solvents and temperature controlled heating systems.
The stillhead forms a critical part of the Soxhlet apparatus by directing vapours from the boiling flask into the condenser, then allowing the condensed solvent to return into the extraction chamber. Uniform internal geometry supports consistent vapour flow, smooth condensate return and efficient solvent saturation of the sample thimble. The clarity of BORO 3.3 glass allows technicians to observe reflux behaviour, solvent movement and extraction progress without interrupting the process.
Soxhlet stillheads are widely used in analytical chemistry, natural product extraction, environmental testing and quality control laboratories. Typical applications include extracting lipids from food matrices, isolating active compounds from plant materials, determining pesticide residues and preparing samples for chromatographic analysis. The robust design ensures compatibility with standard condensers, extraction bodies and flasks, providing reliable integration within existing laboratory setups.
Every stillhead supplied by LabChoice Australia undergoes ISO 9001 aligned quality control testing. This includes dimensional verification of joint tapers, wall thickness checks, clarity inspection and assessment of condensate pathways to confirm consistent performance. Each unit is examined for structural integrity, smooth glass transitions and secure joint fit before packing. This rigorous process ensures that laboratories receive a high quality, dependable component capable of supporting accurate and repeatable Soxhlet extractions.
