Glass Funnel 24-40 (100mm Dia)

A Glass Funnel 24/40 (100mm Dia) is a piece of laboratory glassware designed to transfer liquids or powders into containers with small openings, while also helping to filter or direct substances with ease. The key characteristics of this funnel are its 24/40 ground glass joint and its 100mm diameter, which are specifically tailored for use in laboratory experiments and setups. Here’s a detailed description of its features and applications:

Key Features and Characteristics:

1. Glass Material:

• The funnel is made of high-quality borosilicate glass, known for its resistance to thermal shock, chemical corrosion, and durability. This makes it suitable for use with a wide range of chemicals, solvents, and other laboratory substances.
• Borosilicate glass is non-reactive, which ensures that the funnel won’t contaminate the materials it comes into contact with.

2. 24/40 Ground Glass Joint:

• The 24/40 refers to the size of the ground glass joint:
  • 24 mm is the outer diameter (OD) of the joint.
  • 40 mm refers to the length of the joint.
• The ground glass joint ensures a tight, leak-proof seal when the funnel is connected to other pieces of laboratory equipment that have a matching 24/40 female or male ground glass joint. This joint is commonly used in laboratory distillation systems, filtration setups, or reactions where secure and airtight connections are essential.
• The ground glass surface helps to create a smooth and durable connection, making the funnel easy to attach and remove from other glassware without slipping or losing contact.

3. 100mm Diameter:

• The 100mm diameter of the funnel refers to the size of the wide, conical opening at the top. This large diameter allows for the efficient transfer of liquids or powders into larger containers, such as flasks, beakers, or bottles.
• The larger diameter is particularly useful when dealing with larger volumes of liquids or when a high flow rate is required, as it reduces the risk of spillage and clogging that can occur with smaller funnels.

4. Conical Shape:

• The conical design of the funnel is standard for laboratory funnels. The tapering shape helps guide the substance being poured directly into the neck of the receiving container, minimizing the risk of spillage.
• The shape is ideal for filtering or funneling substances that need to be directed into a small opening.

5. Usage in Laboratories:

• Filtration: A Glass Funnel 24/40 (100mm Dia) is used in filtration setups, where it holds a filter paper in place. The larger diameter can accommodate large filter papers, making it ideal for filtering larger quantities of liquids or powders.
• Liquid Transfer: It can be used for pouring liquids from one container to another, especially when precision is needed. The wide opening helps prevent spills and facilitates quicker transfer.
• Distillation and Reaction Setups: In distillation or reaction apparatus, the 24/40 joint allows for the funnel to be securely connected to other glassware, such as receiving flasks or condensers.
• Separation Processes: The funnel can also be used in processes like liquid-liquid extraction, where it is sometimes used with a separatory funnel or during the addition of reagents to a solution.

6. Versatility and Compatibility:

• The 24/40 ground glass joint is a standard size found in many laboratory systems, ensuring that this funnel is compatible with a wide variety of other laboratory glassware, such as flasks, condensers, or separators. This makes it a versatile piece of equipment in many different setups.
• Its large diameter and sturdy design make it appropriate for both general laboratory use as well as more specific tasks like filtration under vacuum or transferring liquids into vessels with small necks.

7. Cleaning and Maintenance:

• As with most glassware, the Glass Funnel 24/40 (100mm Dia) is easy to clean, as glass does not absorb chemicals and is highly resistant to staining. Cleaning typically involves rinsing with water and using appropriate solvents or cleaning agents when necessary.
• The ground glass joint should be handled with care to avoid breakage. It is best to clean and dry the joint thoroughly to maintain a proper seal and prevent residue buildup.

Summary:

A Glass Funnel 24/40 (100mm Dia) is an essential piece of laboratory equipment, designed for transferring liquids or powders and for use in filtration processes. With its 100mm diameter, it is well-suited for handling larger quantities of substances, while the 24/40 ground glass joint ensures a secure, leak-proof connection with other glassware. The large opening and conical shape make it highly effective for directing materials into smaller containers or for filtering applications. Its durability and chemical resistance make it a reliable tool for a wide range of laboratory tasks, from distillation to liquid handling.
