Natural Convection Oven Programmable 99L Overview
The Yamato DVS402C is a 99 L programmable natural convection oven for drying, curing and heat treatment from room temperature +5°C to 260°C. Without a fan, it suits powders and light samples that forced air would disturb, and it holds ±1.0°C control accuracy at 260°C.
The DVS402C (115V) and DVS412C (220V) are the previous-generation DVS part numbers; Yamato's current models are the DVS403C and DVS413C. A 6-pattern, 30-step program controller, a large observation window and stainless steel chamber are standard. LabSupplies.com is an authorized Yamato Scientific dealer.

Frequently Asked Questions
What is the difference between the DVS402C and the DVS412C?
Voltage only. The DVS402C runs on 115V (12 A, with plug) and the DVS412C on 220V (6.5 A, no plug, round terminal). Both are 99 L.
How do the DVS402C and DVS403C differ?
The DVS402C is the previous-generation part number; the DVS403C is Yamato's current 99 L DVS model. Yamato publishes the specifications on this page for the DVS402C/412C.
Is the DVS402C programmable?
Yes. It stores 6 patterns with up to 30 steps and also runs fixed-temperature, auto start, auto stop and quick auto-stop modes.
Does the DVS402C use a fan?
No. It is a natural (gravity) convection oven, which avoids blowing light or powdered samples around the chamber.
What are the dimensions and weight of the DVS402C?
Internal 450 × 490 × 450 mm, external 560 × 601 × 820 mm (22.0 × 23.7 × 32.3 in), about 48 kg.
What safety devices does the DVS402C have?
Self-diagnostics for sensor, heater, SSR and memory faults with automatic overheating prevention, an overheat prevention device, and an electric leakage breaker with overcurrent protection.
Where is the Yamato DVS402C manufactured?
Yamato Scientific lists China as the country of origin.
