LAB1ST Largee Size VO Series Vacuum Drying Oven covers the full range from pilot-scale to production-scale vacuum processing in a single, configurable platform. Choose 500 L or 1000 L of chamber volume, then choose your heating architecture — uniform chamber heating for gentle, even drying, or independent shelf heating for faster ramp-up, higher temperatures up to 250 °C, and per-shelf temperature control.
Every configuration shares the same core build: a stainless steel 304 working chamber, a calibrated 4th-generation LCD temperature controller with a 1–9999 minute countdown timer, an oil-filled mechanical vacuum gauge, a dedicated inert gas inlet valve, a standard KF vacuum port, an independent over-temperature protector, and a thickened electrostatic powder-coated cold-rolled steel cabinet.
Key Features:
- Two chamber volumes, one platform — 500 L and 1000 L, fully customizable from 23 L to 1000 L
- Two heating architectures — chamber heating (up to 200 °C) or independent shelf heating (up to 250 °C)
- Up to 250 °C working temperature with ±1 °C stability and 0.1 °C control resolution on 1000 L models
- Vacuum down to <50 Pa via standard KF25 or KF40 vacuum ports
- Stainless Steel 304 interior — durable, easy to clean, non-contaminating
- Independent shelf temperature control — run a different temperature on each shelf in a single cycle
- Heating time under 30 minutes on the 1000 L shelf-heated models
- Calibrated 4th-generation controller with programmable 1–9999 minute countdown timer
- Dedicated inert gas inlet valve — N₂ or other inert gases; quick-plug Φ6 mm push-in fitting on 1000 L models
- Vertical chamber design for ergonomic front loading and a smaller footprint
- Ceramic fiber cotton insulation on 1000 L models — lower heat loss, lower surface temperature
- Comprehensive safety suite — leakage protection, over-temperature protection, overload protection, plus an independent over-temperature protector on 500 L models
- Thickened electrostatic powder-coated cabinet — strong corrosion resistance for production environments
- Wide option range — 7″ PLC touchscreen, digital vacuum gauge, vacuum controller, cold trap, chiller, oil-free screw pump, high-vacuum (<1 Pa), 300/400/500 °C high-temp builds
