Product Introduction

Precision vacuum oven is a sealed chamber device used for drying materials under negative pressure. It achieves low-temperature, rapid, and non-oxidizing drying by creating a low-pressure environment within the sealed chamber and combining it with precise heating. Unlike ordinary convection ovens that rely on hot airflow to remove moisture, vacuum ovens use a vacuum pump to evacuate the air from the chamber, reducing the internal pressure, and then combine this with a thermal radiation heating system to achieve highly efficient drying.

Precision vacuum oven mainly consists of a chamber, a vacuum system, a heating system, and an electrical control system. The chamber is a highly airtight sealed space; the vacuum system evacuates the air from the chamber, creating a negative pressure environment. The chamber typically uses a stainless steel lining and an SECC steel outer shell, and is equipped with a double-layered vacuum glass door for easy observation and enhanced insulation. The sealing structure uses a one-piece molded silicone rubber sealing ring to ensure the maintenance of a high vacuum level.

Application areas

Precision vacuum oven are widely used in scientific research, quality inspection, and production processes, including pharmaceuticals and biotechnology, electronics and semiconductors, aerospace and automotive, materials science and research, and clinical and diagnostic laboratories, among others.

Product Main Advantages

product-582-582

Programmable Automatic Control: Batch Oven are equipped with a microcomputer PID controller, supporting multi-segment temperature program settings, including heating rate, temperature hold, and cooling process. Users can program complex temperature-time-vacuum curves according to process requirements, achieving fully automatic operation without human intervention.
Low-Temperature High-Efficiency Drying: In a vacuum environment, the boiling point of water can be lowered to below 40°C, far below the drying temperature of over 100°C required by traditional ovens. This characteristic allows heat-sensitive substances to be thoroughly dried without thermal decomposition.
Oxidation-Free Environment Protection: During the vacuum process, a large amount of oxygen is expelled from the chamber, significantly reducing the oxygen content and effectively preventing oxidation, discoloration, and performance degradation of heat-sensitive and easily oxidized materials during heating. The precision vacuum oven can also be filled with inert gases such as nitrogen or argon through an inert gas interface to further protect samples from oxidation damage, making it suitable for substances that are extremely sensitive to oxidation.
Deep Solvent Removal Capability: It can thoroughly remove bound water and organic solvents from the material, making it particularly suitable for processes requiring strict humidity control.
Safety Protection System: Equipped with independent over-temperature protection, over-current protection, door interlock, and keypad lock functions. Some models also feature a manual inflation valve, allowing manual restoration of internal and external pressure in the event of a power outage in the vacuum system, ensuring safe opening of the oven door.
