No. 4 Vacuum Flask Stopper
Vacuum Flask Stoppers are essential tools designed for deairing operations, ensuring a tight, leak-proof seal during testing procedures. These stoppers are compatible with a variety of laboratory flasks, including Pycnometer Flasks, Volumetric Flasks, and Iodine Flasks, making them versatile for multiple applications. Each stopper features a single hole with a durable metal barbed fitting, allowing for quick and secure connection to 3/8-inch vacuum tubing.
Stopper Compatibility:
- No. 1 Stopper: Fits 250ml Volumetric Flasks, ideal for smaller-scale testing.
- No. 2 Stopper: Fits 500ml Volumetric Flasks, suitable for medium-sized applications.
- No. 4 Stopper: Fits 1,000ml Volumetric Flasks and all Iodine Flasks, perfect for larger-scale or specialized operations.
Key Features:
- Provides a reliable, leak-proof seal for consistent and efficient deairing.
- Equipped with a metal barbed fitting for fast and secure vacuum tubing connections.
- Made from durable, high-quality materials to withstand rigorous laboratory use.
Applications: Vacuum Flask Stoppers are commonly used in soil density testing, specific gravity analysis, and other laboratory procedures requiring deairing. Their compatibility with standard test equipment makes them an essential accessory for accurate and efficient results.
Compliance with Industry Standards:
- AASHTO T100: Standard method for determining the specific gravity of soils.
- ASTM D854: Standard test for the specific gravity of soil solids by water pycnometer.
With their durability, versatility, and compliance with key testing standards, Vacuum Flask Stoppers are an indispensable addition to any laboratory focused on precision and reliability.
