Description
The MEDILAB Essential Oil Determination Apparatus, also known as the Clevenger Apparatus, is a precision glass assembly designed for the quantitative determination of essential oils in plant materials. It operates on the principle of steam distillation, enabling accurate separation and measurement of volatile oils from botanical samples. This apparatus is a fundamental tool in chemical, pharmaceutical, and agricultural laboratories where high-accuracy extraction and quality assessment are essential.
Key Features
- Manufactured from high-quality Borosilicate Glass 3.3 for maximum chemical and thermal resistance.
- Precision-designed condenser and receiver ensure efficient oil separation and accurate volumetric measurement.
- Integrated stopcock at the receiver for easy drainage and controlled collection.
- Suitable for continuous operation during long distillations without performance loss.
- Excellent transparency for clear observation of distillate and oil-water separation.
- Leak-proof joints ensure safe handling of steam and volatile compounds.
- Compatible with commonly used solvent entrainers, including those heavier than water.
