Jeio Tech ON4 Series Ovens – Precision Heating for Laboratory Applications
At Acorn Scientific, we’re proud to partner with Lab Companion to bring you the latest innovation in laboratory equipment: the ON4 Series Natural Convection Oven. This advanced oven series is the perfect solution for laboratories requiring superior temperature stability and precision, particularly for drying sensitive samples like powders or materials prone to temperature fluctuations.
Why Choose the ON4 Series?
The ON4 series represents a significant upgrade over previous models, such as the ON3 series, with improvements that streamline your workflow and ensure reliable, consistent results.
1. Exceptional Temperature Stability with Multi-Path Airflow

The ON4 series introduces a multi-path convection system that delivers exceptional uniformity in temperature distribution. Unlike single-path airflow systems, the ON4 oven circulates heated air more efficiently across the chamber, resulting in:
| Index | ON3-03 | ON4-03 | ON3-05 | ON4-05 | ON3-10 | ON4-10 | ON3-15 | ON4-15 |
| Fluctuation (±℃) | 0.3 | 0.4 | 0.3 | 0.5 | 1.1 | 0.5 | 0.5 | 0.5 |
| Variation (±℃) | 2.7 | 2.8 | 3.7 | 2.6 | 7.5 | 3.6 | 4.1 | 3.5 |
| Recovery time (min) | 18 | 17 | 34 | 19 | 39 | 10 | 35 | 9 |
- Reduced Fluctuation: The ON4-10 model boasts a temperature fluctuation as low as 0.5°C, a major improvement from the previous 1.1°C.
- Improved Variation: Across all models, temperature variation has been significantly minimized, ensuring consistent drying and heating conditions.
- Faster Recovery Time: Recovery times have improved by up to 74% compared to the ON3 series, allowing you to work faster and more efficiently.
2. User-Friendly Touch Controls for Simpler Operation
Ease of use is critical in busy laboratories, and the ON4 series delivers with its upgraded touch screen displays:

- The ON4-V model features a 5-inch touch display, providing an intuitive interface for quick adjustments and monitoring.
- The ON4-S model includes a 3.5-inch touch screen, offering the same ease of use in a compact design.
| Model | ON4-V | ON4-S |
| Controller Size | 5" Touch LCD | 3.5" Touch LCD |
| Data Storage | O | - |
| (Automatic Data Saving & USB Export) | ||
| Recommended Temperature Settings | O | - |
| (3 frequently used presets) | ||
| Real-time Graph Display | O | - |
| Ramp Rate Setting | O | - |
| Recent Event Records | 36ea | 12ea |
| (Errors, Door Open, etc.) |
These responsive touch interfaces replace older VFD displays, streamlining setup and operation so you can focus on your experiments.
3. Regulatory Compliance with 21 CFR Part 11 for Data Integrity

For laboratories conducting pharmaceutical or GMP-compliant research, the ON4 series offers optional 21 CFR Part 11 compliant software. With the LC Data Keeper software, you can ensure data integrity and meet FDA regulatory requirements, making the ON4 a reliable choice for FDA-regulated and GMP-certified facilities.
