Forced Convection Oven Programmable 90L Overview
The Forced Convection Oven Programmable 90L (model DKV400) is a forced convection laboratory oven from Yamato Scientific, supplied by LabSupplies.com as an authorized dealer. Built for constant-temperature work across an operating range of ambient +10 to 270°C, this 90 L unit holds samples at a stable setpoint for drying, curing, and heat-conditioning routines.
Interior surfaces use stainless steel for cleanability and corrosion resistance, while the exterior carries a baked-on finish over chromium-free electrogalvanized steel sheet. A 3.5 inch color LCD controller drives programmable temperature profiles, and click-function door hinges hold the door in place during loading. Built-in cable and exhaust ports support pass-through wiring and controlled venting.
Two voltage builds cover common lab circuits: DKV400 runs on 115V and DKV410 on 220V. Each oven measures 36 × 36 × 43 inches and weighs 190 lbs. Manufactured in Japan, this platform is backed by Yamato's ISO 9001:2015 and ISO 14001:2015 certifications.

- Durable exterior: baked-on finish over chromium-free electrogalvanized steel sheet.
How to Choose the Right Convection Oven
Matching a forced convection oven to your workflow comes down to a few measurable axes. Weigh chamber size, temperature ceiling, control sophistication, and your facility's power before specifying a unit.
- Capacity: chamber volume sets how many samples or how large a load you can process per cycle; this model offers a 90 L chamber.
- Temperature range: confirm the oven reaches your process temperature with margin; this unit operates from ambient +10 to 270°C.
- Control type: programmable controllers let you run multi-step profiles and repeatable setpoints rather than manual adjustment.
- Voltage: select the build that matches your circuit, 115V (DKV400) or 220V (DKV410), to avoid retrofits.
- Footprint: verify the 36 × 36 × 43 inch dimensions and 190 lbs weight fit your bench or floor space and load path.
- Construction: a stainless steel interior aids cleaning and resists corrosion in routine lab use.

Frequently Asked Questions
What temperature range does the DKV400 convection oven reach?
The DKV400 operates from ambient +10 to 270°C. This forced convection range supports drying, curing, and constant-temperature conditioning across most general laboratory protocols.
What is the chamber capacity and overall footprint?
The oven provides a 90 L chamber. The full unit measures 36 × 36 × 43 inches (L × W × H) and weighs 190 lbs, so confirm bench or floor clearance and load path before installation.
What is the difference between the DKV400 and DKV410?
Voltage is the only difference: DKV400 is the 115V build and DKV410 is the 220V build. Both share the 90 L capacity, ambient +10 to 270°C range, and identical construction. Choose the model that matches your facility's circuit.
What materials are used in the oven construction?
The interior is stainless steel for cleanability and corrosion resistance. The exterior uses a baked-on finish over chromium-free electrogalvanized steel sheet for durability.
