Desiccators with Knob
Whatsapp Order
Desiccators with Knob are specialized laboratory containers designed to preserve moisture-sensitive materials by providing a dry, airtight environment. Constructed from high-quality borosilicate glass or durable plastic, these desiccators feature a tightly sealed lid with a central knob for easy handling and secure closure. The knob allows convenient lifting and placement of the lid without compromising the internal vacuum or dry atmosphere. Commonly used with desiccant agents like silica gel, they are ideal for drying samples, storing hygroscopic chemicals, or preventing atmospheric contamination. Desiccators with knobs are indispensable in laboratory, pharmaceutical, and industrial settings for maintaining low-humidity conditions during experiments or storage.
