Superior Moisture Protection for Sensitive SamplesLabcare-Onlines Glass Desiccators provide a meticulously sealed environment that safeguards samples from atmospheric moisture. The robust construction and vacuum-sealing capabilities ensure dependable storage even for the most delicate compounds. Their clear, borosilicate glass not only offers chemical resistance but also guarantees effortless monitoring of contents without exposure.
Flexible Application and Reliable PerformanceDesigned with a removable, perforated porcelain plate, these desiccators accommodate different sample sizes and types of desiccants. Their high vacuum capability (up to 740 mm Hg) makes them suitable for standard and vacuum drying applications. Available in a range of dimensions, they can be autoclaved, supporting stringent laboratory hygiene protocols.
FAQs of Glass Desiccators Labcare-Online:
Q: How should I assemble and seal the Glass Desiccator for optimal vacuum performance?
A: To assemble, place the removable perforated porcelain plate inside the desiccator base. Add your desiccant (silica gel or anhydrous calcium chloride) below the plate, then position your sample above. Ensure the ground flange lid is seated properly and create the vacuum by applying the appropriate grease or a rubber ring before attaching. Seal the lid and evacuate air to the desired vacuum level, up to 740 mm Hg.
Q: What are the primary benefits of using a vacuum glass desiccator compared to a standard desiccator?
A: A vacuum glass desiccator provides superior moisture removal by lowering the internal pressure, enabling faster and more thorough drying of sensitive samples. The robust borosilicate glass and reliable air-tight seal ensure chemical resistance, clear visibility, and long-term protection from humidity.
Q: When should I consider replacing the porcelain plate or desiccant in my desiccator?
A: The removable porcelain plate should be replaced if it shows signs of cracks or significant wear. Regularly inspect your desiccant: silica gel can be regenerated by drying, while calcium chloride should be replaced if it becomes liquefied or no longer effectively absorbs moisture.
Q: Where can I use this glass desiccator and what kinds of samples are suitable?
A: This desiccator is suitable for laboratories, research institutions, and industrial settings, ideal for storing and drying moisture-sensitive samples such as powders, reagents, and hygroscopic substances. Its chemical resistance and vacuum capability make it applicable in a wide array of scientific processes.
Q: What is the process for autoclaving the desiccator for sterilization?
A: Ensure the desiccator is completely clean and devoid of desiccant and samples before autoclaving. The borosilicate glass body and porcelain plate can withstand autoclaving temperatures up to 120C. Always remove the rubber ring or any grease prior to autoclaving to prevent damage or residue formation.
Q: How do the various sizes of glass desiccators differ in terms of use?
A: Different inner diameter options (150 mm, 200 mm, 250 mm, and 300 mm) accommodate varying storage capacities and sample sizes. Select the size based on your laboratorys requirements and the volume of materials needing desiccation.
