White Base Space Saver Vacuum Desiccator

Bel-Art Products, 42010-0000, White Base 140mm Space Saver Vacuum DesiccatorThe unique shape offers maximum interior clearances for more or larger contents without further crowding the benchtop. The thick walls ensure a rugged shatter resistant unit that simply stores a vacuum or stays sealed even if not under vacuum. The included polypropylene stopcock has a vivid, red handle to immediately determine its orientation and a port that accepts 1/4" (6.4mm) I.D. vacuum tubing. The top section can be lifted off using the large ribbed knob at the top center. A Neoprene O-ring offers a secure seal, which does not require grease, but is unaffected if grease is applied. A rigid, perforated polypropylene plate, 3.2 mm (1/8") thick supports the contents and leaves space underneath for desiccant backup if desired. The plate is removable and can be replaced with Scienceware® High Heat Desiccator Plates (catalog numbers F42038-0140, F42038-0190, F42038-0230 depending on size) to support hot crucibles.
