Basic Vacuum Extractor

The HM-15 Basic Vacuum Extractor uses a heavy-wall 4L Filter Flask for collection when testing to determine bitumen in hot-mix asphalt paving mixtures. The Extractor is supported by three legs, and has a 12.25x4.5in (311x114mm) aluminum funnel ring, perforated stainless steel filter support plate and an O-Ring seal. The Hose and Stopper Assembly has a 6ft (1.8m) rubber vacuum hose to fit the 3/8in (9.5mm) OD drain connection and a No.12 neoprene stopper with glass tubing to fit the Filter Flask.
