Features:
Pear-shaped or cylindrical body with a conical bottom
Equipped with a stopcock at the bottom for controlled liquid release
Fitted with a ground glass or plastic stopper at the top
Designed to separate immiscible liquids (like oil and water) based on density differences
Allows easy decanting of lower or upper liquid layers
Transparent (glass) for clear visibility of phase separation
Easy to clean and reuse in multiple lab processes
Common in organic chemistry, extraction, and liquid-liquid separation
