The Kjeldahl Flask is a specialized piece of laboratory glassware used primarily for the determination of organic nitrogen content (Kjeldahl method). Featuring a unique pear-shaped (oval) body and an extra-long neck, it is designed to facilitate digestion and distillation processes. The long neck acts as a primary air condenser, reducing the loss of reagents during vigorous boiling, while the oval body ensures concentrated heating at the bottom for uniform distillation.

Key Features

Premium Borosilicate 3.3 Glass: Highly resistant to thermal shock and chemical corrosion, specifically designed to withstand the use of concentrated sulfuric acid at high temperatures.

Optimal Digestion Design: The oval body shape allows vapors to concentrate and bubble at the center of the base, ensuring even heat distribution and stable reaction.

Integrated Reflux Function: The elongated neck serves a cooling purpose, allowing vapors to condense and reflux back into the flask, minimizing sample loss.

Professional Application: Essential for agricultural research, soil analysis, and organic chemistry labs for nitrogen content analysis and digestion reactions.

Precision Manufacturing: Features a reinforced rim for durability and consistent wall thickness for safety under high-heat conditions.
