Description
The MEDILAB Clevenger Apparatus is a precision-built distillation assembly used for the quantitative determination of volatile oils lighter than water from plant materials. Designed for accurate extraction via steam distillation, it provides laboratories with a reliable method to measure essential oils, flavours, fragrances, and volatile botanical components. Its robust construction and excellent clarity make it an essential tool for R&D, quality control, and academic environments worldwide.
Key Features
- Manufactured from durable Borosilicate Glass 3.3 for superior thermal and chemical resistance.
- An efficient condenser ensures rapid cooling and effective separation of volatile fractions.
- Integrated oil-separatory tube provides precise and direct volume measurement.
- Leak-proof ground-glass joints offer secure connections during distillation.
- Transparent, smooth glass surface allows clear visibility of phase separation.
- Designed for continuous use in extended distillation applications.
- High-accuracy graduations enhance measurement precision and reproducibility.

Handling & Precautions
- Assemble the unit securely, ensuring all ground-glass joints are properly greased (if required).
- Always maintain a steady flow of cooling water through the condenser during distillation.
- Avoid subjecting hot glassware to sudden cooling to prevent thermal stress.
- Clean using mild laboratory detergents; avoid abrasive cleaners and strong alkalis.
- Suitable for autoclaving up to 121°C; avoid direct flame on glass surfaces.
- Store in a clean, stable environment to protect joints and graduations from damage.
Applications
- Extraction of volatile oils from botanicals, herbs, spices, and plant samples
