Several different dissector options and accessories are available to control hygroscopic and other contamination during the cooling of samples after those samples have been heated in the Muffle Furnace (Model 42127).

The Desiccator Chamber (PN 0042147) features a sealed glass lid and glass vertical walls and bottom. It also includes a porcelain plate with a desiccant storage area below (desiccant sold separate).

The Desiccator Cabinets (PN 0042147-JA and PN 0042147-JB) feature a stainless steel frame and two stainless steel shelves with an included desiccant tray (desiccant sold separate).  There is also a manual relief valve that allows the equalization of the chamber pressure prior to opening the door.  The reusable desiccant changes color as it absorbs moisture and will change back to blue from pink when heated to 218°C (424.5 °F) for one hour.  Two desiccant sizes are available: 0.45kg (1 lb.) and 2.25kg (5 lbs.).
