The Kjeldahl Flask in the laboratory is a dedicated glass apparatus employed in the Kjeldahl nitrogen determination method. It is fabricated from high borosilicate glass, which exhibits superior chemical and thermal stability, high transparency, and significant mechanical strength. The structure, featuring a long neck, functions for condensation. It is utilized for nitrogen determination in fields such as agriculture, food, chemical engineering, and the environment.

1. Material: High borosilicate glass, characterized by superior chemical and thermal stability, high transparency, and considerable mechanical strength.
2. Structure: Long-necked condenser, ground-joint sealing, and diverse capacities.
3. Performance: Specifically dedicated to the Kjeldahl nitrogen determination method, offering precise determination and convenient operation.

Technical data

Working Environment Conditions:
1. Temperature: Ranging from normal temperature to approximately 300°C. Extreme high temperatures and sudden temperature changes should be avoided.
2. Ventilation: Operations should be carried out in a fume hood to prevent the hazard of harmful gases.
3. Illumination: Direct intense light should be avoided to prevent the deterioration of samples or reagents.
4. Atmospheric Pressure: Generally used under normal pressure. Special experiments require attention to pressure resistance.

Precautions:
1. Before Use: Inspect the appearance of the flask to ensure no cracks or damages exist, and it is clean and dry.
2. Control of Heating Temperature: Violent boiling should be avoided.
3. Handle with Care: Prevent collisions.
4. Cleaning and Storage: Clean promptly after use to avoid residues and store in a dry and well-ventilated place, away from corrosive gases.
5. Chemical Properties: Prolonged contact with strongly alkaline and other corrosive chemicals should be avoided to prevent the erosion of the glass surface.
6. Prevention of Sudden Temperature Changes: To avoid the generation of thermal stress leading to the fracture of the flask.
7. Attention to Condensation Effect: The outside of the long neck can be appropriately wiped for cooling, but avoid direct contact of water with the overheated area.
