Inert Oven Programmable 95L Overview
The Inert Oven Programmable 95L (model DN411IE) from Yamato Scientific creates a non-oxidizing process environment by purging its 95 L chamber with nitrogen gas. Heat treatment and heat-resistance testing run across a +15 to 360°C operating range. LabSupplies.com supplies this oven as an authorized Yamato Scientific dealer.
Key Features
- Nitrogen atmosphere: N₂ gas is introduced into the chamber to produce a non-oxidizing environment, with controllable flow amount.
- Temperature range: operates from +15 to 360°C for heat-resistance testing and heat treatment.
- Programmable control: stores up to 99 patterns of 99 steps each with a repeat function.
- Operation modes: program operation, calibration offset, power-failure recovery selection, and user configuration saving.
- Safety package: self-diagnostic functions, digital setting, independent overheat prevention device, and an electric leakage breaker.
- Door switch protection: fan and heater turn off automatically if the door is opened during operation.
How to Choose the Right Inert Oven
- Capacity: the 95 L chamber sets how many parts or sample trays you can process per cycle; size it to your batch volume.
- Temperature range: a +15 to 360°C ceiling determines which heat-treatment and heat-resistance protocols the oven can run.
- Footprint and weight: Yamato lists external dimensions (W × D × H) of 640 × 695 × 915 mm (25.2 × 27.4 × 36.0 in); packed for shipping it measures 36 × 36 × 46 in at 290 lb.

Frequently Asked Questions
What is the temperature range of the DN411IE inert oven?
The DN411IE operates from +15 to 360°C. This range supports heat-resistance testing and heat treatment within a non-oxidizing nitrogen atmosphere.
What is the chamber capacity and external footprint?
The oven provides a 95 L chamber. Yamato lists external dimensions (W × D × H) of 640 × 695 × 915 mm (25.2 × 27.4 × 36.0 in); packed for shipping it measures 36 × 36 × 46 in at 290 lb.
How does the oven maintain a non-oxidizing environment?
Nitrogen gas is introduced into the chamber to displace oxygen. The N₂ flow amount is controllable to suit the process during heat treatment.
Can processes be programmed and repeated?
Yes. The controller stores up to 99 patterns of 99 steps each with a repeat function, plus calibration offset and power-failure recovery modes.
What is the UNSPSC code for the Yamato DN411IE?
The Yamato DN411IE is classified under UNSPSC 41104501 (laboratory mechanical convection ovens).
How does the Yamato DN411IE compare with the other DN Series models?
Yamato builds this DN Series line in 2 sizes: 95 L (DN411IE) and 223 L (DN611IE). All share accuracy ±0.2°C (at 360°C). The comparison table on this page lists capacity, exterior and shipping weight side by side.
How accurate and uniform is the temperature in the Yamato DN411IE?
Yamato rates the DN411IE for temperature accuracy at ±0.2°C (at 360°C) and temperature distribution at ±3°C (at 360°C).
