Overview
The YAMATO DG410C, DG810C, and DG850C series are precision-engineered forced-air laboratory drying ovens designed for reliable, contamination-controlled drying of glassware, metal instruments, and other heat-stable laboratory utensils. Unlike conventional natural-convection ovens, the DG850C integrates a dedicated axial-flow exhaust fan and dual intake filtration to actively remove moisture-laden air—enabling faster equilibration, reduced condensation risk, and improved hygiene during post-wash drying cycles. All models operate within a controlled temperature range of ambient +5°C to 70°C and employ PID-based digital temperature regulation with K-type thermocouple feedback and independent mechanical over-temperature protection. The double-wall insulated chamber construction minimizes thermal loss while maintaining uniform internal conditions—critical for consistent drying performance across repeated operational cycles in GLP-compliant environments.
Key Features
- Double-wall insulated chamber with high-efficiency thermal barrier design for stable temperature uniformity and low external surface temperature
- Stainless steel interior (SUS304) and corrosion-resistant painted cold-rolled steel exterior for durability and easy decontamination
- Stainless steel tubular heating elements (1.0 kW for DG410C; 1.34 kW for DG810C/DG850C) mounted at the base with integrated water collection tray to safely accommodate wet instrumentation
- Large observation window (250 × 300 mm or 250 × 700 mm) for real-time visual monitoring without door opening
- DG850C-specific enhancements: side-mounted forced-exhaust fan (axial flow), dual 30 mm intake ports with particulate filters, and built-in 15 W germicidal UV lamp for surface disinfection during drying
- Digital PID controller with dual LED displays: green 4-digit measured temperature, red 4-digit setpoint; adjustable via intuitive ▲/▼ keys and function menu navigation
- Comprehensive safety architecture including self-diagnostic circuitry (for sensor failure, SSR short-circuit, and temperature overshoot), independent mechanical overheat limiter, earth leakage circuit breaker (ELCB), and key-lock function
Sample Compatibility & Compliance
These ovens are validated for drying volumetric glassware (e.g., pipettes, burettes, flasks), stainless steel forceps, spatulas, crucibles, and ceramic labware. The non-condensing airflow design of the DG850C is particularly suited for high-moisture-load applications such as autoclave-cooled instrument sets. Internal chamber materials comply with ISO 15190:2020 requirements for laboratory equipment safety and cleanliness. The stainless steel interior meets USP criteria for suitability in analytical instrument qualification. While not classified as medical devices, the DG850C’s UV lamp supports supplemental microbial reduction per ISO 15858:2016 guidelines for UV-C disinfection in non-critical surfaces.
Software & Data Management
The DG-series employs embedded firmware—not PC-dependent software—with full audit trail capability for critical parameters. Temperature setpoints, timer values, operational modes (constant-run, auto-stop, delayed start), and deviation correction offsets are stored in non-volatile memory. Power interruption recovery preserves both current settings and elapsed timer data (power-loss compensation). Though no external data logging interface is provided, the system supports manual verification of calibration traceability through documented sensor calibration records and periodic verification using NIST-traceable reference thermometers—fully compatible with FDA 21 CFR Part 11 requirements when integrated into laboratory quality management systems.
Applications
- Routine drying of sterilized or washed laboratory glassware and metallic tools prior to storage or use
- Moisture removal from hygroscopic reagents after transfer or weighing procedures
- Pre-conditioning of sample containers and sampling vessels in environmental and pharmaceutical QC labs
- Controlled low-temperature desiccation of calibration standards and reference materials
- UV-assisted surface sanitation of non-critical labware in microbiology support areas (DG850C only)
- Stabilization of humidity-sensitive instrumentation components prior to assembly or testing
FAQ
What distinguishes the DG850C from the DG810C?
The DG850C adds forced-air exhaust via an integrated axial fan, dual filtered intake ports, and a 15 W UV-C germicidal lamp—features absent in the DG810C.
Is the UV lamp ozone-free?
Yes—the lamp emits at 254 nm and is designed for low-ozone generation, suitable for use in ventilated laboratory spaces without additional exhaust ducting.
Can the oven be used for sterilization?
No—these units are drying ovens, not sterilizers. They do not achieve or validate the time–temperature profiles required for microbial lethality per ISO 17665 or EN 285.
What is the maximum load capacity per shelf?
Each stainless steel wire mesh shelf supports up to 15 kg; standard configurations include 10 shelves (DG410C) or 29 shelves (DG810C/DG850C) spaced at 30 mm intervals.
Does the system support IQ/OQ documentation?
Yes—YAMATO provides factory calibration certificates and technical specifications compliant with ISO/IEC 17025 requirements, enabling straightforward installation and operational qualification by end users.
