- Gravity convection provides gentle natural airflow to help protect powders, lightweight materials, and delicate samples from being disturbed during heating
- PID temperature control supports consistent, repeatable heating for routine laboratory processes
- Fast heat-up and recovery performance helps the oven return to operating conditions efficiently during everyday workflows.
- Stainless-steel interior construction with rounded corners helps simplify routine cleaning and maintenance
- Overtemperature protection provides additional monitoring for safer operation
- Flexible shelf positioning helps accommodate different sample sizes and makes effective use of the available chamber space
- Insulated chamber design helps retain heat for efficient drying, sterilization, heat treatment, and heated storage applications
The VWR 65L Gravity Convection Oven, Cat. # 89511-404 provides gentle, controlled heating and drying for laboratory applications where forced air movement may disturb delicate materials. Its gravity convection design relies on natural airflow, making it particularly well suited for powders, lightweight samples, and other materials that could be displaced by an active circulation system. The oven can support a variety of routine workflows including drying, heat treatment, sterilization, and heated storage.
A PID temperature controller provides straightforward operation while helping maintain consistent conditions for repeatable laboratory processes. The gravity convection design provides gentle, natural airflow throughout the chamber, making the oven well suited for heating and drying delicate or lightweight samples. Sensor based overtemperature protection provides additional monitoring during operation.
The stainless-steel interior features rounded corners for easier routine cleaning, while flexible shelf positioning helps accommodate different sample sizes and laboratory workflows. An insulated chamber design helps retain heat for efficient operation, and the compact footprint provides useful 65 L capacity without unnecessarily consuming bench space.
