Fine Oven Programmable 91L Overview
The Yamato Scientific Fine Oven Programmable 91L (model DF412) is a mechanical convection laboratory oven delivering a 91-liter chamber and an operating range from ambient +15°C to 260°C. Engineered for demanding temperature-characteristic testing, it pairs accurate thermal control with a redesigned panel for clearer readouts and faster setup. LabSupplies.com supplies this unit as an authorized Yamato Scientific dealer.
Construction centers on a stainless steel interior chamber paired with a chrome-free electrogalvanized carbon steel exterior, finished in a chemical-proof baked-on coating. An adjustable air-speed function manages uniformity, while an exhaust damper enables quick venting and chamber cool-down. Dedicated exhaust and cable ports support real-world test configurations.
Operating on 220V, the DF412 measures 49 × 33 × 43 inches and weighs 365 lbs, suiting permanent benchtop or floor placement. Manufactured in Japan, the oven is produced under ISO 9001:2015 and ISO 14001:2015 certified processes. Onboard displays report power consumption, CO₂ emission, and heat-timer status.
Key Features
- Programmable control: enhanced program operation supports up to 99 steps and 99 patterns with a repetitive operation function.
- Wide temperature range: operates from ambient +15°C up to 260°C with precise stability and uniformity.
- Adjustable air speed: standard air-speed control helps manage chamber temperature uniformity for varied loads.
- Monitoring displays: readouts for power consumption, CO₂ emission, and heat timer keep test conditions visible.
- Exhaust damper and ports: rapid venting plus dedicated exhaust and cable ports speed cooling and accommodate test wiring.
- Safety detection: fan motor error detection improves operational safety during unattended runs.
How to Choose the Right Fine Oven
Selecting a fine oven comes down to matching chamber size, thermal range, and control complexity to your test protocols and the power available at your site. Use the criteria below to confirm the DF412 fits your workflow.
- Capacity: the 91L chamber sets how many samples, fixtures, or trays you can process per cycle — verify your largest test load fits.
- Temperature range: ambient +15°C to 260°C covers most curing, aging, and characteristic-testing protocols; confirm your target setpoints fall inside it.
- Control type: programmable multi-step operation suits complex, repeatable temperature profiles rather than single fixed setpoints.
- Voltage: this unit requires 220V — check that the appropriate circuit and receptacle are available at the install location.
- Footprint and weight: at 49 × 33 × 43 inches and 365 lbs, plan placement and floor or bench support before delivery.
- Safety features: fan motor error detection matters for labs running long, unattended thermal cycles.
