Natural Convection Oven Programmable 99L Overview
The Natural Convection Oven Programmable 99L (DVS403C) from Yamato Scientific is a programmable convection oven built around a 99 L chamber for drying, curing, and general thermal processing. LabSupplies.com, an authorized dealer, supplies the genuine unit with manufacturer warranty.
Natural convection drives heat through gravity-based airflow, delivering gentle, low-turbulence circulation that suits powders, lightweight samples, and protocols sensitive to forced-air disturbance. Programmable control supports repeatable multi-step routines, so a saved profile reproduces the same conditions run after run.
Two voltage configurations cover most lab infrastructure: the DVS403C runs on 115V and the DVS413C runs on 220V. Both share the 99 L capacity and programmable platform. Detailed chamber dimensions, materials, and temperature ratings are available on request from our equipment specialists.
Key Features
- Natural convection heating: gravity-based airflow provides gentle, uniform thermal circulation without forced-air turbulence.
- Programmable control: multi-step temperature programming reproduces protocols consistently across runs.
- 99 L chamber: large-capacity workspace for batch drying, curing, and routine heat processing.
- DVS403C: 115V configuration for standard North American single-phase circuits.
- DVS413C: 220V configuration for higher-voltage lab infrastructure.
How to Choose the Right Convection Oven
Matching an oven to your workflow means weighing throughput, control needs, and site power . Use these axes to confirm fit.
- Capacity: a 99 L chamber sets how many samples or how large a batch you can process per cycle; size it to your peak load.
- Control type: programmable control enables saved multi-step profiles for repeatable, validated protocols, while simpler analog units suit single-setpoint tasks.
- Convection style: natural convection favors gentle, low-disturbance drying; forced-air designs prioritize speed and tighter uniformity.
- Voltage: confirm your bench circuit before ordering, choosing the 115V DVS403C or the 220V DVS413C.
- Footprint: verify bench or floor clearance against the unit's external dimensions and ventilation requirements.

Frequently Asked Questions
What is the difference between the DVS403C and DVS413C?
Voltage is the only difference: the DVS403C operates on 115V and the DVS413C operates on 220V. Both models share the same 99 L chamber capacity and programmable convection platform, so you choose based on your available bench circuit.
What is the chamber capacity of this oven?
The chamber capacity is 99 L. This large-volume workspace supports batch drying, curing, and general heat processing for multiple samples per cycle.
Is this a programmable oven or single-setpoint?
It is a programmable oven. The controller supports multi-step temperature programming, letting you save and reproduce protocols consistently rather than manually setting a single fixed temperature.
Does this oven use forced air or natural convection?
It uses natural convection. Gravity-driven airflow circulates heat gently with low turbulence, which suits powders, lightweight materials, and samples sensitive to forced-air movement.
What is the maximum operating temperature?
Detailed temperature ratings are available on request from our lab-equipment specialists. Contact LabSupplies.com for the full temperature specification before issuing your .
What are the external dimensions and weight?
External dimensions and weight are available upon request. Reach our equipment team at LabSupplies.com to confirm bench or floor clearance and shipping details for the DVS403C or DVS413C.
