The **Desiccator Vacuum** by ESAW India (C-57 Series) is an essential, high-utility glassware item engineered for demanding laboratory environments. Made from premium-grade, **heavy-duty transparent glass**, it provides a **perfect air-tight seal** necessary for safely storing moisture-sensitive chemical substances and executing controlled **vacuum drying procedures**. The inclusion of a precision **stopcock** allows for effective vacuum application and pressure release.
Whether you need to **store hygroscopic compounds**, dry precipitates to a constant weight, or protect analytical samples from atmospheric humidity, this laboratory desiccator delivers superior performance. Available in sizes from 150mm to 300mm, it serves as a critical tool for **students, researchers, and industrial quality control teams** worldwide.
The Desiccator Vacuum operates by creating an environment where both humidity and air pressure are drastically lowered, ensuring rapid and complete sample drying.
Applying a vacuum dramatically lowers the boiling point of water and other solvents. This allows samples to dry significantly faster and at lower temperatures than atmospheric drying, protecting heat-sensitive materials.
The airtight seal, coupled with a desiccant (like silica gel) placed below the perforated plate, creates an extremely dry atmosphere. This is essential for storing **hygroscopic substances** (which absorb moisture from the air) and standard analytical reference materials.
Crucial for gravimetric analysis, where accurate mass measurement is needed. Samples like dried precipitates are cooled and stored under vacuum conditions to ensure no ambient moisture re-absorption occurs before weighing.
The desiccator consists of a heavy base, a **perforated desiccation plate**, and a ground glass lid. The **precision stopcock** connects to a vacuum pump. Once the sample is placed and the vacuum is applied, the air and moisture are pulled out. The tight seal maintains the low pressure and the low humidity established by the desiccant material.
A plain desiccator only uses a desiccant (drying agent) to remove atmospheric moisture. The **Desiccator Vacuum** includes a stopcock, allowing it to be connected to a vacuum source, which drastically **accelerates the drying process** and is necessary for storing highly sensitive compounds.
Commonly used desiccants include **anhydrous calcium chloride, silica gel (often indicating type), or phosphorus pentoxide**. The choice depends on the material being dried and the required level of dryness.
The ground glass joint between the base and the lid must be kept clean and lightly greased with **high-vacuum grease** to ensure an optimal airtight seal and prevent the lid from seizing.
While the desiccator is made from durable glass, it is primarily for **cooling, drying, and storage** under vacuum or ambient conditions. Samples should be cooled to room temperature before placing them inside under vacuum.
