Jeio Tech | Forced Convection Ovens Standard OF4 S | 250°C Precision Heating Oven With Touchscreen Control and Advanced Safety Features
The Jeio Tech OF4-S Forced Convection Oven is a reliable and affordable laboratory oven designed to deliver consistent heating performance for everyday laboratory applications.
Available at Alto Med Supply, this standard-type laboratory oven combines essential heating functions with user-friendly controls, making it ideal for research labs, testing facilities, industrial environments, and quality control applications.
Equipped with a 3.5-inch touch controller, the OF4-S allows users to easily monitor and adjust operating settings through an intuitive interface.
The built-in Wait On and Wait Off timer functions help improve workflow efficiency by allowing precise scheduling of heating cycles and test operations.
This laboratory convection oven offers a wide temperature range up to 250°C and uses a stable control system for reliable heating accuracy.
Its advanced three-point temperature calibration helps maintain precise temperature control across a broad operating range, while optimized airflow distribution ensures uniform heat transfer throughout the chamber.
The oven maintains excellent temperature uniformity with deviations of ±1.9°C or lower at 100°C.
For added convenience, users can set upper and lower temperature limits, and the built-in alarm system quickly alerts operators when temperature deviations occur.
Optional RS-232 and USB connectivity allow easy PC-based monitoring and data management, while optional LC Connected mobile monitoring enables remote control and real-time status monitoring from virtually anywhere.
The system also supports optional BMS communication and 21 CFR Part 11 compliant LC Data Keeper integration for GMP-compliant environments and audit-ready data management.
Safety is a key feature of the Jeio Tech OF4-S oven. The upper vent design helps effectively release fumes when connected to local ventilation systems, while the exterior surface remains safe to touch even during high-temperature operation.
Additional protection features include an advanced overheating protection system, over-temperature limit function, and IEC Protection Class II equivalent safety standards.
Designed for improved laboratory efficiency, the oven automatically records up to 12 recent operating events, including start and stop times, operating duration, and error history.
The Hands-free™ door system allows convenient opening while handling samples, and the optional stacking kit helps maximize workspace efficiency by safely stacking two units together.

What a life saver. The chair arrived in a big box. Was very easy to assemble. Just unfold and attach the foot pedals. Mom is now able to cruise around her complex visiting friends and participating in activities.
This bed is brilliant, and the technology is brilliant. It is a stunning bed that has helped mobility for my wife who has a spinal cord injury and has trouble getting in and out of bed as well as chairs. Her quality of life will be better because of this product.Thank you.
