Natural Convection Oven 74L Overview
The Natural Convection Oven 74L (Yamato Scientific model DX402C) is a constant-temperature drying oven offering a 74 L chamber and an operating range of ambient +5 to 300°C. Built for routine drying, curing, and sterilization, this oven pairs digital PID control with simple daily operation. LabSupplies.com supplies it as an authorized Yamato Scientific dealer.
A steel-plate SPCC exterior with powder-coat finish protects the unit on busy benchtops, while the stainless steel interior resists corrosion and wipes clean between runs. Digital PID regulation holds temperature accurately across the chamber, and a calibration offset lets technicians align readings to a reference probe.
Self-diagnostic safety functions watch the heating circuit during unattended runs. Choose 115V (DX402C) or 220V (DX412C) to match site power. Measuring 36 × 36 × 39 in and weighing 170 lbs, the oven is manufactured under ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certified systems.

How to Choose the Right Convection Oven
Matching a convection oven to your workflow comes down to a few measurable axes. Weigh the points below against your sample volume, process temperatures, and facility power before ordering.
- Capacity: a 74 L chamber handles moderate batch sizes; confirm your largest tray or glassware load fits the interior.
- Temperature range: verify your process stays within ambient +5 to 300°C, the operating window of this model.
- Control type: digital PID control with a calibration offset supports repeatable, documentable results for QC work.
- Voltage: select 115V (DX402C) or 220V (DX412C) to match the circuit at your installation point.
- Footprint and weight: at 36 × 36 × 39 in and 170 lbs, plan adequate bench or floor space and clearance.
- Safety: self-diagnostic functions matter for labs running overnight or unattended drying cycles.

Frequently Asked Questions
What is the temperature range of the Yamato DX402C convection oven?
The DX402C operates from ambient +5 to 300°C. Digital PID control with a calibration offset holds temperature accurately throughout that range, supporting drying, curing, and sterilization tasks.
What is the chamber capacity and overall footprint?
The chamber holds 74 L. Overall dimensions are 36 × 36 × 39 in (L × W × H), and the unit weighs 170 lbs, so plan adequate bench or floor space and clearance before installation.
What is the difference between the DX402C and DX412C?
Voltage is the only difference. The DX402C runs on 115V and the DX412C runs on 220V; both share the same 74 L chamber, ambient +5 to 300°C range, and digital PID control. Select the model that matches your site power.
What materials are used in the oven construction?
The interior is stainless steel for corrosion resistance and easy cleaning. Its exterior is steel plate (SPCC) with a powder-coat finish that protects the unit on the bench.
Does this oven use natural convection or forced air?
This is a natural (gravity) convection oven. Air circulates without a fan, which reduces sample disturbance and particle movement inside the chamber during drying.
Is the DX402C manufactured under recognized quality standards?
Yes. It is produced under ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certified management systems. Certification documents are available on request.
