VO 400 Memmert: Precision Vacuum Drying for Demanding Laboratory Applications
The Memmert VO 400 vacuum oven is a high-performance laboratory device designed for controlled thermal drying of heat-, oxygen-, or moisture-sensitive substances. Utilizing direct heating through thermal shelves, it ensures uniform heat distribution and optimal accuracy, even under deep vacuum conditions. This model is widely used in pharmaceutical, biotechnological, chemical, and electronic sectors for operations such as desiccation, decontamination, polymer cross-linking, and the treatment of hygroscopic materials.
With a 49-liter chamber, the VO 400 features a multipoint control system based on MLC microprocessor technology, combined with independent Pt100 temperature sensors for each heating shelf. This allows for real-time monitoring and precise regulation of each heating zone, while minimizing thermal deviation.
The user interface enables intuitive programming of complex cycles via an 8-character alphanumeric digital display. Users can create up to 40 customizable ramps, combining temperature and pressure settings, with each segment adjustable from 1 minute to 999 hours. An automatic restart function ensures process continuity in the event of a power outage—an essential feature for high-security laboratories.
The inner chamber is made from 316L stainless steel, known for its corrosion resistance, hygiene, and ease of cleaning. The structure is hermetically welded, and removable elements such as rails, diffusers, and shelves facilitate maintenance. The exterior design includes a safety double-glass door, providing clear visibility of the chamber contents while ensuring airtightness and operator safety.
The integrated safety system includes visual and audible alarms, both electronic and mechanical limiters, and automatic shutdown in the event of overtemperature. A calibration certificate at +160 °C and 50 mbar is provided for each heating shelf, ensuring compliance and performance from the moment of installation.
Versatile, reliable, and easy to integrate into existing workflows, the VO 400 can be customized with a wide range of accessories, including a vacuum pump module, additional shelves, or communication interfaces (Ethernet, RS485).
The Memmert VO 400 is the ideal solution for laboratories seeking precise vacuum drying control in full compliance with quality, reproducibility, and traceability standards.
