High Temperature Natural Convection Oven Programmable 13.75L Overview
The High Temperature Natural Convection Oven Programmable 13.75L (model DR201), supplied by LabSupplies.com as an authorized Yamato Scientific dealer, is a programmable gravity convection unit operating from 300°C to 700°C across a 13.75 L chamber. Engineers deploy it as a constant temperature oven, a drying oven, and an electric furnace for ashing or sintering.
Interior surfaces use stainless steel SUS304, while the exterior carries a steel plate melamine resin coating. High-accuracy control holds the setpoint across the elevated temperature band. A high-operability controller manages temperature, measured temperature, and overheat-prevention values through the operation menu and ▲/▼ keys.
Available in 115V and 220V configurations, the oven measures 28 × 28 × 34 inches and weighs 111 lbs. Manufactured in Japan, this DR201 carries ISO 9001:2015 and ISO 14001:2015 certifications. Confirm footprint and shipping weight against bench space and freight requirements before installation.

How to Choose the Right Convection Oven
Selecting a high-temperature convection oven comes down to matching the chamber, thermal range, and site power to your workflow. Weigh these axes before specifying a unit.
- Temperature range: verify the oven reaches your process setpoint; the DR201 covers 300°C to 700°C for ashing, sintering, and high-temperature drying.
- Capacity: a 13.75 L chamber suits small-batch and bench workflows; size the chamber to your largest sample or fixture.
- Control type: programmable digital control with auto start and auto stop supports unattended, repeatable runs.
- Voltage: confirm 115V or 220V availability against your facility's circuit and outlet.
- Footprint and weight: at 28 × 28 × 34 inches and 111 lbs, ensure adequate bench support and clearance.
- Material compatibility: an SUS304 stainless interior resists corrosion during demanding thermal cycles.
