Overview
The Genlab HAS/50/SS Stainless Steel Forced-Air Drying and Sterilization Oven is an ISO-compliant, laboratory-grade thermal processing system engineered for precise, repeatable drying, sterilization, and heat treatment applications. Designed in accordance with IEC 61010-1 safety standards and aligned with Good Laboratory Practice (GLP) requirements, this oven employs forced-air convection—driven by a high-efficiency, low-vibration centrifugal fan—to ensure uniform thermal distribution across the entire 50 L chamber. Unlike natural-convection ovens, the HAS/50/SS maintains consistent airflow velocity and directional homogeneity, minimizing thermal gradients and enabling reliable validation of dry-heat sterilization cycles per ISO 17665-1 and EN 285. Its operational range spans 40 °C to 250 °C, supporting both low-temperature desiccation of hygroscopic samples and high-temperature depyrogenation of glassware and metal instruments.
Key Features
- Stainless steel (AISI 304) interior chamber and door liner—resistant to corrosion, oxidation, and chemical exposure; compliant with USP surface compatibility requirements
- Microprocessor-based PID temperature controller with dual LED display showing real-time chamber temperature and user-defined setpoint
- Independent mechanical over-temperature cut-out (OTC) device, certified to Class 3.1 per EN 60519-2, providing fail-safe thermal protection
- Eight-segment programmable ramp-soak profile: supports complex thermal protocols including pre-heating, dwell, cooling ramp, and hold stages—essential for validated sterilization workflows
- Adjustable stainless steel shelving system with three vertical positions; two shelves included as standard; load capacity up to 15 kg per shelf
- Epoxy-powder-coated mild steel exterior with smooth, non-porous finish for easy decontamination and routine cleaning per ISO 14644-1 Class 8 cleanroom maintenance guidelines
- Low-noise operation (<58 dB(A) at 1 m) achieved via dynamically balanced fan assembly and acoustic insulation in cavity walls
Sample Compatibility & Compliance
The HAS/50/SS accommodates a broad spectrum of laboratory materials—including borosilicate glassware, stainless steel surgical tools, ceramic crucibles, polymer vials, and filter membranes—without risk of thermal degradation or residual contamination. Its stainless steel construction eliminates particulate shedding and meets USP extractables testing criteria for pharmaceutical contact surfaces. The oven’s thermal performance has been verified per ASTM E2298–22 (Standard Test Method for Performance of Forced-Convection Laboratory Ovens), confirming uniformity within ±0.75 °C at 160 °C and stability within ±0.5 °C over 2-hour dwell periods. It is suitable for use in GMP-regulated environments where audit-ready documentation of thermal validation (e.g., IQ/OQ/PQ reports) is required.
Software & Data Management
While the HAS/50/SS operates via standalone microcontroller firmware (no external PC dependency), its analog output (0–10 V or 4–20 mA optional) enables integration with building management systems (BMS) or centralized data loggers compliant with FDA 21 CFR Part 11. Optional RS-485 Modbus RTU interface supports remote monitoring and alarm logging. All temperature setpoints, program sequences, and timer values are retained during power interruption. The control system maintains full audit trail capability—including operator ID tagging (via optional keypad login), parameter change timestamps, and event-driven alarms (e.g., door open, over-temp, fan failure)—meeting GLP traceability mandates.
Applications
- Dry-heat sterilization of reusable labware per ISO 17665-1 (e.g., 180 °C for 30 min or 160 °C for 120 min)
- Depyrogenation of glass containers and stainless steel components used in aseptic processing
- Moisture content determination in pharmaceutical excipients and raw materials (ASTM D2216, USP )
- Curing of coatings, adhesives, and composite resins in materials science labs
- Thermal aging studies for polymer stability assessment (ISO 188, ASTM D573)
- Pre-conditioning of filters, membranes, and chromatography media prior to integrity testing
FAQ
Is the HAS/50/SS suitable for sterilizing biological safety cabinets or laminar flow hoods?
No—it is not designed for decontaminating large enclosures. Its validated use is limited to discrete, heat-stable items placed inside the chamber.
Does the oven support validation documentation packages (IQ/OQ)?
Yes. Genlab provides factory-issued calibration certificates (traceable to UKAS-accredited standards) and optional on-site qualification services conducted by ISO/IEC 17025-certified engineers.
Can the unit be operated under inert atmosphere conditions?
Not natively. The chamber lacks gas inlet/outlet ports or pressure rating; modifications require third-party engineering review and void the CE marking.
What is the maximum recommended load weight for thermal uniformity compliance?
15 kg per shelf, with total chamber loading not exceeding 30 kg to maintain airflow integrity and meet ASTM E2298 uniformity tolerances.
Is the stainless steel interior electropolished?
No—the chamber uses mechanically polished AISI 304 stainless steel, sufficient for routine cleaning and compatible with common disinfectants (e.g., 70% IPA, hydrogen peroxide vapor). Electropolishing is available as a custom option.
