Jeio Tech OV-4, 28 Litre Vacuum Oven

With a temperature range of up to 250°C, Jeio Tech’s OV-11, 28 Litre Vacuum Oven is suitable for various test applications (e.g. agricultural genetics, drying of plant tissue, drug metabolism) and optimally constructed to separate solvents from solutions or dry solvents with high boiling points.

This lab vacuum oven comes with microprocessor PID control, temperature calibration, dual wait on/off timer modes (1min to 99hr 59min), and automatic tuning. Safety features include a keypad lock function to prevent accidental changes during operation, automatic run after power interruption and over-temperature and over-current protection.

Key Features


  • Temperature range from ambient +5°C to +250°C
  • Vacuum Range: 0 to 0.1MPa (analogue vacuum gauge). Drying a solvent in vacuum lowers its boiling point, thereby making the separation process easier and eliminating the need to use high temperatures
  • Uniform heat distribution from block type heater directly to the anodised aluminium shelves
  • Microprocessor PID control / temperature / calibration / automatic tuning


  • Intuitive control panel with bright LED display (1°C resolution)
  • Dual wait on/off timer modes (1min to 99hr 59min)
  • Convenient pre-setting function for three most commonly used temperature settings
  • Viton (fluorine rubber) door gasket also available for acidic applications (optional)
  • Heat tempered glass window provides clear inside view of the chamber
  • Tight vacuum seal thanks to spring-loaded glass door, silicone gasket and a push-button latch handle




  • Keypad lock function prevents accidental changes during operation
    • Automatic run after power interruption
    • Over-temperature and over-current protection


  • Temperature variation up to ±1.5℃ at 100℃ according to
    DIN 12880:2007standards
    • Outer surfaces remain safe to touch even whilst operating at
    the highest temperature, preventing possible burns when viewing
    samples via the inspection window
    • 5inch color touch display for intuitive operation
    • Wide temperature range that can be controlled up to 250℃
    • 3-point temperature calibration improves temperature accuracy in the entire area.
    • Monitor and control via mobile app anytime, anywhere via LC Connected. (mobile monitoring system) – Optional
    • Polycarbonate safety cover provided to protect a user in case of tempered glass breakage
