Jeio Tech OV4-30 Vacuum Oven (28L), 120V, 60Hz, US Plug-OV4-30

Jeio Tech OV4 Advanced Vacuum Ovens are designed for heat-sensitive, easily oxidized, or powdered materials requiring precise and gentle drying. By lowering the boiling point through vacuum pressure, the OV4 enables effective drying at reduced temperatures while minimizing thermal degradation and oxidation. Its robust construction ensures consistent performance, while the intuitive control system offers precise temperature regulation and safety features. Ideal for applications in pharmaceuticals, electronics, and materials research, the OV4 delivers reliable and uniform vacuum drying with exceptional ease of use.Application Laboratory ovens are used for high-temperature applications such as drying, curing, sterilizing, and heat-treating samples and equipment. Vacuum ovens are designed to dry, cure, or heat samples under reduced pressure, allowing for lower-temperature processing and minimizing oxidation or thermal degradation. They are ideal for drying heat-sensitive, moisture-sensitive, or oxidation-prone materials, such as powders, delicate electronics, pharmaceuticals, and biological samples. By removing air and moisture through vacuum, these ovens provide gentle, uniform drying and are widely used in chemistry, biotech, electronics, and materials research for safe, contamination-free thermal processing.

Wide temperature range that can be controlled up to 250°C.
Improved temperature distribution. (±1.5°C at 100°C)
3-point temperature calibration, high temperature accuracy over a wide temperature range.
Inner stainless steel and aluminum shelves provide excellent corrosion resistance and clean maintenance.
Protects equipment from overcurrent and over temperature through safety circuits.
Vacuum line and release line are separated and convenient to use.
The display is mounted at the top, minimizing floor sizerequirement.
Use Convenience Features

When a vacuum is formed and maintained, the toughened glass is attached to the gasket, so it is kept confined for long-time repeated use.
Save and use 3 frequently used temperatures.
PC connection using RS-232 port and USB port.
Excellent visibility and viewing angle due to application of 5-inch large LCD.
Wait On/Off timer. (up to 999 hours 59 minutes)
Toughened glass viewing window for easy internal viewing.
Microprocessor PID method for precise temperature control.
Automatic restart as it was operated after power recovery.
Monitor via mobile app anytime, anywhere with LC Connected. (mobile monitoring system) (when purchased LC GreenBox)
Microprocessor PID method for precise temperature control.
Outstanding Safety

Door structure including buffer system allows for internal pressure release through upper and lower ventilation holes when stable vacuum is formed/maintained and when there is an internal explosion.
Polycarbonate safety cover provided in case of toughened glass breakage.
12 events is recorded in case of door open, error, and etc.
Top-rated overheating protection system. (registration 10 – 0397583)
Over temperature limit function.
Safe product surface, even when operated at upper temperature.
Malfunction prevented by controller lock function.
Alarm if set temperature deviation outside of acceptable range.
Vacuum Oven Use Configuration

It is recommended to use the cold trap bath on the vacuum line to protect the weak vacuum pump against water/solvent or to supply dry air to the sample.
