Bel-Art 420220000 Space Saver 190mm Vacuum Desiccator with Clear Polycarbonate Bottom & Cover
The space saving design of the vacuum desiccator dome provides maximum interior clearances. This provides an average of 13% greater interior volume than standard hemispherical domes. This economical desiccator will remain air tight even when not under vacuum. A polypropylene stopcock with a Teflon® TFE plug turns smoothly allowing a slow, gentle entrance of air preventing unnecessary turbulence and crucible damage. The desiccator lid includes a neoprene O-ring gasket seal which does not require stopcock grease. However, stopcock grease may be used for a more secure seal and will not harm the gasket or desiccator. The bottom plate also features 1/8-Inch diameter perforations for air transfer and is 1/8-Inch thick. The plate rests on the retaining ledge of the bottom section and has a center hole for easy removal.
