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
• Quality control testing in the pharmaceutical, herbal, cosmetic, and food industries
• R&D studies involving essential oils, aromatic chemicals, and natural products
• Teaching and demonstration in academic chemistry and biochemistry laboratories
• Analytical procedures in biotech, agricultural, and QC/QA laboratories

The Clevenger Apparatus plays a critical role in standardising volatile oil content—a key parameter for purity, potency, and formulation studies.
