Overview
The Memmert UFE500 Forced Convection Drying Oven is an ISO 17025-aligned, GLP-compliant benchtop laboratory oven engineered for precise thermal processing across research, quality control, and production environments. Utilizing a robust forced-air circulation system with adjustable fan speed and manually regulated fresh-air admixture, the UFE500 maintains stable, homogeneous temperature distribution within its 108 L stainless-steel chamber (material 1.4301 / ASTM A240 Type 304). Designed for applications ranging from moisture removal and pre-drying of samples to accelerated aging tests and stability studies, the oven operates over a certified temperature range of +20 °C to +250 °C (optional extension to +300 °C), with a minimum operating temperature of +30 °C per DIN 12880 requirements. Its triple-layer overtemperature protection architecture—comprising mechanical TB-class 1 limiters, electronic TWW-class 3.1 controllers, and microprocessor-based TWB-class 2 monitoring—ensures continuous compliance with IEC 61010-1 safety standards.
Key Features
- Chamber constructed entirely from deep-drawn, electropolished 1.4301 stainless steel (ASTM 304), fully recyclable and resistant to corrosion, cleaning agents, and thermal cycling
- Forced convection system with continuously adjustable fan speed (10–100% in 10% increments) and manual fresh-air damper for optimized airflow and vapor extraction
- E-Class precision control system featuring fuzzy-logic PID regulation, three-point automatic temperature calibration, and dual 4-wire Pt100 Class A sensors (one operational, one redundant)
- Integrated 1024 kB circular memory buffer recording actual values, setpoints, alarms, timestamps, and error logs at 1-minute intervals—supporting >6 months of continuous data retention
- Comprehensive overtemperature protection: mechanical limiter (TB), electronic controller fail-safe cutoff (+10 °C above setpoint for U/S variant), and microprocessor-based Pt100 diagnostics with ASF (Automatic Setpoint Following)
- RS232 interface standard; compatible with Memmert’s Celsius 2007 software for unlimited ramp-soak-cool profile programming, remote monitoring, and audit-trail generation compliant with FDA 21 CFR Part 11
- Full-featured digital display with 8-character alphanumeric menu navigation, multilingual UI (D/UK/E/F/I), and real-time visualization of temperature, time, fan speed, and damper position
Sample Compatibility & Compliance
The UFE500 accommodates diverse sample formats—including Petri dishes, glassware, metal trays, and polymer components—on five sliding stainless-steel shelves (max. load 30 kg/shelf, total chamber load 60 kg). Its chamber geometry (560 × 480 × 400 mm W×H×D) and uniform air distribution meet DIN 12880 Class 2 homogeneity specifications (±2.2 °C at 150 °C). The unit is CE-marked, conforms to EN 61010-1:2019 for laboratory equipment safety, and supports traceable calibration via factory-issued certificate (center-point verification at 160 °C). Optional STERI chip cards enable automated sterilization cycles (4 h @ 160 °C), satisfying microbiological lab requirements under ISO 14644 and EU GMP Annex 1.
Software & Data Management
Celsius 2007 software (Windows NT4 through Windows 10 compatible) provides full bidirectional control, enabling creation of complex multi-segment thermal profiles—including delayed start, ramp-to-setpoint, dwell, and programmable cooling. All logged data are exportable in CSV or PDF format with embedded metadata (operator ID, instrument serial number, calibration status). The system supports electronic signatures, user-level access control (admin/operator/guest), and immutable audit trails required for ISO/IEC 17025 accreditation and pharmaceutical QC documentation per USP and ICH Q5C.
Applications
- Drying of filter papers, soil samples, and pharmaceutical excipients per ASTM D2234 and USP
- Thermal aging of polymers and composites per ISO 188 and ASTM D573
- Pre-conditioning of test specimens prior to tensile, impact, or adhesion testing (ISO 291, ASTM D618)
- Stability testing of active pharmaceutical ingredients (APIs) under ICH Q1A(R2) guidelines
- Residue determination in food and environmental analysis (AOAC 990.19, EPA Method 3540C)
- Moisture content validation for ceramic and powder metallurgy feedstocks (ISO 787-2)
FAQ
What is the maximum certified operating temperature of the UFE500?
The standard configuration is rated to +250 °C; an optional upgrade extends the upper limit to +300 °C upon factory configuration.
Does the UFE500 support 21 CFR Part 11 compliance?
Yes—when used with Celsius 2007 software, it delivers electronic signatures, audit trails, role-based access, and data integrity controls aligned with FDA requirements.
How many temperature sensors are installed, and what is their accuracy class?
Two independent 4-wire Pt100 sensors conforming to IEC 60751 Class A (±0.15 °C at 0 °C), with redundancy and self-diagnostic capability.
Can the UFE500 be integrated into a centralized laboratory monitoring network?
Via RS232-to-Ethernet gateways or third-party SCADA systems using Modbus RTU protocol (available as optional firmware module).
Is calibration documentation included with delivery?
Yes—a single-point calibration certificate (center chamber, 160 °C) is supplied; full multi-point calibration kits and IQ/OQ services are available separately.
