Description

American Educational Glass Desiccator with Porcelain Plate, 250mm

With thick walls and a sturdy, removeable, 7.25″ perforated porcelain drying plate, this 8.5″ soda lime glass desiccator is perfect for larger items that require drying. It is a non-vacuum (plain) desiccator, and therefore has no stopcock. The sturdy glass top fits easily on the thick lip of the desiccator, and features a knob handle for removing or replacing the lid. The lips of both the lid and the desiccator itself are ground glass, and should be greased with petroleum jelly before use. In addition to helping create an air-tight seal, the grease also helps cushion the lid when it is set down in place. To help prevent damage from being set down too forcefully, the lid can be carefully slid on, or off, of the desiccator once greased. Desiccators can be used, though not exclusively, for preserving moisture-sensitive items, protecting hygroscopic (water absorbing) or water-reacting chemicals, as well as removing traces of water from samples that need drying. A dessicant (not included) such as silica, calcined quicklime or anhydrous calcium chloride can be put in the lower chamber to be used as the drying agent.

  • Desiccators allow one to store equipment in a low-humidity atmosphere
  • The heavy glass desiccators are made from quality annealed glass for durability
  • It includes a glazed porcelain sample plate with a 4 to 5cm center hole and multiple perimeter holes that is held over the desiccant
  • For an airtight seal
  • Apply grease to the internal edges of the flange, press the lid on and rotate at least 360 degrees
