Iodine Flask With IC Glass Stopper 500ml

An Iodine flask with an interchangeable (I/C) glass stopper is a specialized piece of glassware used in laboratories, particularly for iodometric titrations and other applications involving iodine. It is designed with a ground glass joint and a matching stopper to create an airtight seal, preventing evaporation and contamination of the iodine solution. The flask is typically conical in shape with a narrow neck, similar to an Erlenmeyer flask, but with the added features for secure sealing. Here's a more detailed description:Key Features:

• Conical Shape:Like a standard Erlenmeyer flask, it has a conical body and a narrow neck, allowing for swirling and mixing of solutions. 
• Ground Glass Joint:The flask and stopper have matching ground glass surfaces, which create a tight, airtight seal when connected. 
• Interchangeable Stopper (I/C):The stopper is designed to be interchangeable, meaning it can be easily removed and replaced. This allows for convenient access to the flask's contents while maintaining a seal. 
• Durable Glass:Iodine flasks are typically made of borosilicate glass, known for its resistance to high temperatures and chemical corrosion. 
• Capacity:The flasks come in various sizes (e.g., 100ml, 250ml, 500ml), with the smaller sizes being more common for handling iodine. 

Purpose:

• Iodine Determination:Iodine flasks are essential for iodine value determination according to methods like ASTM D-29. 
• Iodometric Titrations:They are used for titrations where iodine is involved as a reactant or titrant. 
• Storage and Handling:Iodine flasks are suitable for storing and handling iodine solutions, as well as for conducting iodine-based reactions. 
• Airtight Seal:The ground glass joint and stopper provide a secure seal, preventing iodine vapor from escaping and minimizing contamination or evaporation. 
• Versatility:Iodine flasks are versatile tools used in various laboratory applications beyond iodine-related work, including chemical reactions, distillation, and other experiments requiring a sealed flask. 

In summary, the iodine flask with an interchangeable glass stopper is a specialized piece of glassware designed for accurate and safe handling of iodine and iodine solutions, particularly in titrations and other reactions.
