The Vacuum Oven is paramount for processing materials that are **heat-sensitive or prone to oxidation**. By drastically lowering the pressure, the boiling point of solvents is reduced (Clausius-Clapeyron relation). This allows for rapid and complete drying at temperatures significantly lower than $100^\circ\text{C}$, protecting the chemical integrity of the sample, crucial for APIs in **Gujarat and Sikkim**.
Key applications involve **low-temperature drying** of delicate powders (e.g., proteins or pharmaceutical intermediates), **degassing** liquids like epoxies, silicones, and printing inks (removing trapped air bubbles that compromise structural integrity), and pre-treating samples for sensitive analytical techniques. This is essential for electronics assembly in **Pune and Bangalore**.
The oven is indispensable in **Pharmaceutical Quality Control** (moisture content determination), **Aerospace** (curing/bonding of high-strength composites), **Micro-electronics** (cleaning and drying printed circuit boards), and **University Research Labs** across states like **Maharashtra, Tamil Nadu, and Delhi**.
Medico's **Vacuum Ovens** are meticulously engineered chambers built to maintain high vacuum levels while providing precise thermal control. The chamber construction is robust, featuring highly polished, corrosion-resistant stainless steel, often with a double-walled structure to ensure structural stability under high vacuum. A thick, tempered glass viewing window is fitted within a heavy door, secured by a reliable, positive-sealing latch mechanism.
Unlike conventional ovens, heat transfer primarily occurs via **conduction** from the heated shelves directly to the sample containers, as air convection is non-existent in a vacuum. This design ensures maximum thermal efficiency. Features include an inert gas purging port for eliminating oxygen before operation, precise digital PID temperature control, and a vacuum relief valve for safety. We provide models tailored to lab and production scale, ensuring quality and performance for clients across **Karnataka, Haryana, and West Bengal**.
No. A standard water bath vacuum pump typically cannot achieve the deep vacuum levels (e.g., 1 Torr or lower) required for effective low-temperature drying. A specialized **chemical-resistant diaphragm or rotary vane pump** is necessary for optimal performance and to handle solvent vapors.
Purging the oven with an inert gas before drawing a vacuum is critical for two reasons: **Safety** (it removes oxygen, preventing fire/explosion when drying flammable solvents) and **Sample Protection** (it prevents oxidation or degradation of the sample at elevated temperatures).
Safety features include a **shatter-resistant, tempered glass viewing window**, a **spring-loaded safety valve** to prevent over-pressurization during gas back-fill, and high-quality vacuum gaskets and door latches to maintain chamber integrity under high vacuum.
In a vacuum, air molecules are too sparse to efficiently transfer heat through convection. Therefore, heat must be transferred directly to the sample containers via **conduction** from the heated metal shelves to ensure uniform and efficient heating, bypassing the need for air movement.
