Memmert VO49 Vacuum Oven 49L, 230V
Temperature Range
Ambient +5°C to 200°C
Vacuum Range
5 to 1100 mbar
Chamber Volume
49L (1.7 cu. ft.)
The Memmert VO49 Vacuum Oven 49L, 230V stands as a pinnacle of efficiency and precision in the field of vacuum drying. Designed for diverse applications such as drying food, cosmetics, electronic components, and more, this oven guarantees rapid and uniform temperature control through its direct contact between the load and heatable, removable thermoshelves, ensuring no heat loss. This model features digital pressure control that facilitates rapid yet gentle drying, optimizing the process for delicate materials. The VO49 is engineered with a multi-level heating and sensing system, which includes individually placeable thermoshelves equipped with separate sensors for accurate temperature control and short process times. This system reacts dynamically to different loads or humidity levels, maintaining a constant set temperature crucial for effective vacuum drying. Additionally, each thermoshelf can be individually calibrated to meet specific testing requirements.
While the VO49 oven itself is robust and reliable, it is worth noting that the speed-controlled vacuum pump, which enhances the system's energy efficiency by approximately 70%, is available as an optional accessory and is not included as standard. This pump is designed to be chemical-resistant and operates with a low final vacuum of up to 2 mbar, significantly extending the service life of membranes and reducing operational costs. Constructed from high-quality, rust-resistant stainless steel that is easy to clean, the VO49 offers a user-friendly and intuitive operating experience. It is fully programmable via the AtmoCONTROL software, comes with an integrated data logger, and multiple interface options for comprehensive programming and documentation. This makes the Memmert VO49 Vacuum Oven a versatile and essential tool for any lab needing precise and efficient vacuum drying capabilities.
