This means the desiccator can maintain a vacuum level of 740 mm of mercury (approximately 98% of full vacuum) for a full 24-hour period without requiring any vacuum grease to seal the joint between the dome and base. This is achieved through the precision silicon rubber O-Ring seated in the flange groove, which creates an airtight seal without messy greases.
The three-way PTFE stopcock has three positions: 1) Vacuum creation position - connects the desiccator interior to the vacuum source, 2) Shut-off position - isolates the desiccator interior from both vacuum source and atmosphere, maintaining vacuum, and 3) Vacuum release position - slowly allows air to re-enter the desiccator for safe, controlled venting. The self-lubricating PTFE plug operates smoothly without additional grease.
These vacuum desiccators are available in five diameters: 150mm (Code 55204), 200mm (Code 55205), 250mm (Code 55206), 300mm (Code 55207), and 380mm (Code 55210). The size refers to the internal diameter of the desiccator, which determines the size of the desiccant plate and the sample capacity.
Yes, these desiccators are fully autoclavable. The polypropylene base and polycarbonate dome can withstand standard autoclaving temperatures (121°C). However, always remove the stopcock and O-Ring before autoclaving, as these components may have different temperature tolerances. Allow the desiccator to cool completely before reassembly and vacuum application.
No, these desiccators are designed for grease-free operation. The silicon rubber O-Ring seated in the internal groove creates an airtight seal without any grease. This eliminates the mess and potential contamination associated with traditional vacuum greases, and simplifies cleaning and maintenance.
Common desiccants include silica gel (with or without indicator), activated alumina, molecular sieves, calcium chloride, and calcium sulfate (Drierite). The choice depends on your application and the level of dryness required. Place the desiccant in the provided tray or dish at the bottom of the desiccator, below the perforated plate that holds your samples.
Disassemble the desiccator by removing the dome and stopcock. Wash all components with warm water and mild laboratory detergent. For stubborn residues, use appropriate solvents compatible with polypropylene and polycarbonate. Rinse thoroughly with distilled water. The polycarbonate dome should be cleaned with soft cloths to avoid scratching. Allow all components to air dry completely before reassembly.
Yes, these desiccators can be used for drying solvents over appropriate desiccants. However, ensure that the solvent vapors are compatible with polypropylene, polycarbonate, and the silicon O-Ring. Some organic solvents may damage these materials. Always check chemical compatibility for your specific solvents before use.
These vacuum desiccators are supplied individually, with one piece per pack for all five sizes (55204 through 55210). This allows you to order exactly the size and quantity needed for your laboratory.
