Overview
The Yuelian YL-2201 Precision Benchtop Drying Oven is an engineered thermal processing instrument designed for controlled, repeatable heat treatment of samples in laboratory and quality control environments. Based on forced-air convection heating and PID-driven temperature regulation, the YL-2201 delivers stable thermal profiles across its working volume—enabling applications such as moisture removal, pre-drying of analytical samples, thermal aging of polymers, solvent evaporation, and post-curing of adhesives and coatings. Its compact footprint and modular chamber sizing (six standard configurations) make it suitable for space-constrained labs while maintaining compliance with fundamental thermal validation requirements for routine testing.
Key Features
- Forced-air circulation system ensures uniform heat distribution and minimizes thermal gradients across the chamber—validated to ±1% (±1°C at 100°C) per IEC 60068-3-5 test methodology.
- Dual independent over-temperature protection circuits: primary PID-controlled limit and secondary mechanical cut-off—both certified to EN 61000-6-2/6-4 immunity and safety standards.
- Double-layer tempered glass door with stainless steel frame provides unobstructed visual monitoring without compromising thermal integrity or operator safety.
- PID auto-tuning controller enables rapid stabilization and precise setpoint maintenance, with 0.1°C resolution display and real-time deviation feedback.
- Chamber interior constructed from electropolished SUS#304 stainless steel—resistant to oxidation, corrosion, and residue buildup under repeated thermal cycling up to 500°C.
- Power-fail memory timer supports uninterrupted operation: resumes elapsed time and setpoint upon AC restoration, critical for long-duration stability studies (e.g., ASTM D570, ISO 62).
Sample Compatibility & Compliance
The YL-2201 accommodates a broad range of sample types—including polymer films, elastomeric specimens, pharmaceutical excipients, ceramic precursors, and food-grade packaging materials—within defined thermal limits per configuration. All models meet basic electrical safety requirements under GB 4706.1 and IEC 61010-1 for laboratory equipment. While not inherently GLP/GMP-certified, the oven’s dual-limit safety architecture, traceable temperature display, and programmable timer support audit-ready documentation when integrated into validated workflows (e.g., USP , ISO 17025-compliant QC labs). Optional calibration certificates (NIST-traceable Pt100 sensor) are available for IQ/OQ protocols.
Software & Data Management
The YL-2201 operates via embedded microcontroller firmware with no external PC dependency. Temperature logging is manual via front-panel display; however, optional RS-485 interface (add-on module) enables integration with SCADA systems or LabVIEW-based data acquisition platforms for time-stamped thermal profiling. The unit supports basic electronic record generation—setpoint, actual temperature, elapsed time, and alarm status—compatible with 21 CFR Part 11-compliant archive systems when paired with validated third-party software. No cloud connectivity or proprietary drivers are included.
Applications
- Moisture content determination per ASTM D229, ISO 3745, or pharmacopeial drying loss methods (USP )
- Thermal aging of rubber compounds (ASTM D573), plastics (ASTM D3045), and pressure-sensitive adhesives
- Pre-conditioning of test specimens prior to tensile, peel, or shear testing (ISO 293, ASTM D638)
- Drying of filter papers, crucibles, and glassware in analytical chemistry workflows
- Baking of printed circuit board (PCB) substrates and solder paste stencils in electronics manufacturing QA
- Stabilization of hygroscopic reference standards and calibration weights in metrology labs
FAQ
What is the maximum operating temperature for the YL-2201F model?
The maximum temperature depends on the suffix code: “2” = 200°C, “3” = 300°C, “4” = 400°C, and “5” = 500°C. The YL-2201F-5 configuration supports full-range operation up to 500°C.
Is the oven suitable for inert-atmosphere drying?
No—the YL-2201 is a forced-air convection oven designed for ambient air operation only. It lacks gas purge ports, vacuum capability, or sealed atmosphere control.
Can the internal chamber be cleaned with solvents?
Yes—SUS#304 stainless steel construction resists common lab solvents (e.g., ethanol, acetone, isopropanol); avoid chlorinated or fluoride-based cleaners to prevent pitting.
Does the unit include calibration documentation?
Standard delivery includes factory-set verification at 100°C and 200°C. NIST-traceable calibration certificates with uncertainty budgets are available as a paid option.
What is the typical warm-up time to reach 200°C?
From ambient (25°C), the YL-2201B-3 achieves 200°C in approximately 22–28 minutes under no-load conditions, per ISO 8503-2 thermal response testing.
