Clearly view contents with the transparent PC cover of the Thermo Scientific Nalgene Polypropylene Desiccator with Stopcock. Lighter in weight than glass, the robust polypropylene body is compatible with all solid desiccants and protects against breakage. This desiccator is for room temperature use only and can be used with or without a vacuum.

Features:

• Full vacuum may be applied following supplied instructions for proper performance
• Polypropylene stopcock with PTFE Plug can be used with 0.25″ (6.4mm) ID tubing (tubing sold separately)
• Vacuum connection is located on the desiccator body making the cover easier to handle
• Straight bore design eliminates stopcock vacuum leakage
• No gasket is necessary; grease makes polycarbonate cover airtight even without applying      a vacuum
• Recessed rim keeps grease off benchtop when cover is set down
• Desiccator takes any standard 230mm desiccator plate such as Cat. No. 5312-0230 (sold separately)
