Basic Vacuum Extractor for Bitumen Testing in Asphalt

Basic Vacuum Extractor for Bitumen Testing in Asphalt

The Basic Vacuum Extractor is a reliable and precise tool designed for determining bitumen content in hot-mix asphalt paving mixtures. This extractor is built to meet the rigorous demands of asphalt testing, making it an essential piece of equipment for any laboratory or field testing environment.

Construction and Design

The extractor is supported by three sturdy legs, ensuring stability during operation. It features a 12.25 x 4.5in (311 x 114mm) aluminum funnel ring, a perforated stainless steel filter support plate, and an O-Ring seal for a secure, leak-free connection. Rather than using a collection tank, this extractor uses a heavy-wall 4L Filter Flask to collect solvent, providing a more controlled and efficient extraction process.

Hose and Stopper Assembly

The included Hose and Stopper Assembly consists of a 6ft (1.8m) rubber vacuum hose designed to fit the 3/8in (9.5mm) OD drain connection. A No.12 neoprene stopper with glass tubing is also included to fit securely into the Filter Flask, ensuring a tight seal throughout the extraction process.

Key Features

• Collects solvent with a filter flask instead of a collection tank for more precise results
• Three-legged design for enhanced stability during testing
• Perforated stainless steel filter support plate for durability and longevity
