Overview
The Memmert UFE700 is a high-precision forced-convection drying oven engineered for reproducible thermal processing in research laboratories, quality control environments, and industrial R&D settings. Designed and manufactured in Germany under strict DIN EN ISO 9001-certified production protocols, the UFE700 employs a robust convection architecture based on tangential fan-driven airflow—ensuring uniform temperature distribution across the entire working chamber. Its core measurement principle relies on active air circulation combined with dual 4-wire Pt100 Class A sensors (one for control, one for independent monitoring), enabling real-time feedback regulation and redundancy-critical operation. The unit operates within a temperature range of ambient +5 °C (minimum 30 °C) to 220 °C standard, extendable to 300 °C upon configuration—making it suitable for applications including moisture loss determination (ASTM D2240, ISO 293), polymer aging (ISO 188), pharmaceutical stability testing (ICH Q1A), and pre-conditioning of test specimens prior to mechanical or electrical evaluation.
Key Features
- Chamber constructed entirely from deep-drawn, corrosion-resistant 1.4301 stainless steel (equivalent to ASTM A240/A240M Grade 304), fully recyclable and compliant with EU RoHS Directive 2011/65/EU
- Forced-air circulation system with adjustable tangential fan (0–100% speed control in 10% increments) and manually adjustable fresh-air damper for precise humidity and oxygen exchange management
- E-Class controller featuring fuzzy-logic PID algorithm, triple overtemperature protection (mechanical TB-class 1, electronic TWB-class 2, and microprocessor-based TWW-class 3.1), and automatic self-calibration at three user-defined setpoints
- Integrated 1024 KB ring-buffer memory logging all process parameters—including actual vs. setpoint temperatures, fan speed, damper position, error codes, timestamps—at 1-minute intervals for ≥6 months of continuous traceability
- Comprehensive safety architecture: dual independent Pt100 sensors, fail-safe heater cutoff at +10 °C above setpoint (U/S series) or +3 °C (I-series), audible/visual alarm activation, and automatic shutdown upon sensor fault detection
- RS232 interface standard; compatible with Memmert’s Celsius 2007 software suite for unlimited ramp-soak-cool profile programming, remote monitoring, and GLP/GMP-compliant data export (CSV, PDF)
Sample Compatibility & Compliance
The UFE700 accommodates diverse sample formats—including Petri dishes, crucibles, glassware, polymer coupons, and coated substrates—within its 416 L stainless-steel chamber (1040 × 800 × 500 mm W×H×D). Nine sliding stainless-steel shelves (max. load 30 kg per shelf, total chamber capacity 100 kg) support both static and dynamic loading configurations. All materials contacting the chamber interior meet USP and FDA 21 CFR Part 11 requirements for non-reactivity and extractables profiling. The oven complies with DIN 12880 (temperature homogeneity testing), EN 61000-6-3 (EMC emissions), EN 61000-6-2 (immunity), and IEC 61010-1 (safety for laboratory equipment). Optional STERI chip cards enable validated sterilization cycles (4 h @ 160 °C) for microbiological applications requiring ISO 14644-1 Class 5 cleanroom-compatible hardware.
Software & Data Management
Celsius 2007 software provides full PC-based control, validation support, and audit-trail generation meeting ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). It supports IQ/OQ documentation templates aligned with GAMP 5, enables electronic signature capture, and exports timestamped datasets with metadata (operator ID, instrument ID, calibration status). Internal memory maintains full traceability without external dependency; optional parallel printer interface (PCL3-compatible) allows hardcopy record generation. Firmware updates are delivered via USB-stick or RS232, with version history logged in device memory. All software modules undergo periodic verification per ISO/IEC 17025 Clause 5.9.
Applications
- Moisture content analysis per AOAC 950.46 and ISO 5528

- Drying and curing of thin-film coatings and printed electronics substrates
- Pre- and post-test conditioning of composite materials per ASTM D5229/D5229M
- Stability testing of APIs and excipients under ICH Q1A(R3) guidelines
- Residue ashing preparation prior to elemental analysis (ICP-OES, AAS)
- Controlled dehydration of botanical samples for phytochemical standardization
FAQ
What is the temperature uniformity specification at 150 °C?
Per DIN 12880, the UFE700 achieves ≤ ±2.2 °C spatial variation across the working volume at 150 °C.
Does the UFE700 support 21 CFR Part 11 compliance?
Yes—when operated with Celsius 2007 v4.2+, it delivers electronic signatures, audit trails, role-based access control, and secure data archiving required for regulated environments.
Can the oven be configured for inert-atmosphere operation?
No—standard UFE700 units are not gas-tight; however, optional nitrogen purge kits (with flowmeter and pressure relief valve) are available as accessories for oxygen-sensitive processes.
Is calibration certificate included with shipment?
A factory-issued single-point calibration certificate (center-point, 160 °C) is supplied; full multi-point UKAS-accredited calibration is available as an optional service.
What power supply options are supported beyond 230 V/50–60 Hz?
Three-phase 400 V configurations (400 V/3ph/N) can be ordered ex works; custom voltage variants require lead-time consultation with Memmert Engineering Services.
