The Vacuum Extractor with 3,000g capacity has superior design features for quantitative determination of bitumen in hot-mixed paving mixtures using the vacuum method. Extractor base is a 16in (407mm) dia. x 8in (203mm) high stainless steel extract collection tank with carrying handles, a gauge-fitted vacuum source connection, and an extract drain valve. Two sight-glass gauges are provided to monitor solvent level and color of extract during extraction. A 12.25in (311mm) ID, 4.5in (114mm) high removable funnel ring clamps filter paper and a perforated stainless steel paper support plate to base with a Viton O-ring seal. Sample and solvent are placed on paper inside the ring.
Improved design features anodized aluminum funnel ring for protection from corrosive solvents. Quick-action wing bolt fasteners between ring and base have no exposed threads to damage. Filter paper support plate has disk spacers to prevent collapse under vacuum.
The Vacuum Extractor includes Vacuum Gauge, 100 Filter Papers, stainless steel Filter Support, O-Ring Seal, 4ft (1.2m) Vacuum Hose Connection, and instructions. For best results using biodegradable terpene-based solvents. Vacuum source is required; order vacuum pumps separately. The 4lb carton of Diatomaceous Silica Filtering Aid for slow filtering samples is sufficient for 36 tests.
