Pyrex 5420-500 Kjeldahl Flask 500mL

The Pyrex 5420-500 Kjeldahl Flask 500mL is a specialized piece of laboratory glassware. Specifically, it is designed for Kjeldahl digestion. This method determines nitrogen content in substances.

Key Features:

•  Capacity: 500 milliliters (ml), suitable for medium-scale digestion processes.
• Design: Long Neck: The elongated neck minimizes splashing and loss of sample during heating or boiling. Tooled Rim: The reinforced rim (tooled finish) provides durability and a secure seal when used with stoppers or connectors.
• Material: Made from borosilicate glass (Pyrex), which is highly resistant to thermal shock, chemical corrosion, and mechanical stress.
• K2 Design: The “K2” designation indicates a specific shape and design optimized for Kjeldahl digestion, ensuring efficient heating and mixing of samples.

Applications:

• Primarily used in Kjeldahl nitrogen determination for protein analysis in food, environmental, and agricultural testing.
• Suitable for digestion of organic materials with strong acids (e.g., sulfuric acid) at high temperatures.
• Compatibility: Works with standard Kjeldahl digestion apparatus and heating equipment.

Benefits:

• Durability: Borosilicate glass ensures long-lasting performance even under harsh chemical and thermal conditions.
• Precision: The long neck and tooled rim enhance accuracy by reducing sample loss and improving handling.
• Versatility: Can be used in a variety of laboratory settings for nitrogen and protein analysis
