Overview
The Shanghai LabTech 202-3EBS Electrically Heated Constant-Temperature Drying Oven is a precision-engineered laboratory drying system designed for reliable thermal processing across industrial, pharmaceutical, clinical, and academic settings. Operating on resistive heating principles with forced-air convection, the unit maintains uniform temperature distribution throughout its stainless-steel chamber—critical for applications requiring consistent thermal exposure without localized hot spots or stratification. It delivers stable setpoint control within ±1.0 °C deviation across its operational range (ambient +10 °C to 250 °C), making it suitable for moisture removal, sample pre-conditioning, polymer curing, wax melting, microbiological media sterilization (dry heat method), and residual solvent evaporation in accordance with standard laboratory protocols.
Key Features
- Robust chamber construction using AISI 304 stainless steel—resistant to corrosion, oxidation, and repeated thermal cycling; facilitates easy cleaning and long-term dimensional stability.
- Electrostatically coated carbon-steel outer casing—provides mechanical durability, chip resistance, and uniform aesthetic finish under routine lab handling.
- Double-layer tempered glass observation window integrated into the front door—enables real-time visual monitoring of samples without compromising thermal integrity or introducing ambient air infiltration.
- Modular temperature control architecture—supports interchangeable digital PID controllers (optional configurations available), delivering high repeatability (±0.5 °C typical inter-batch variation) and programmable ramp-hold profiles for process-critical workflows.
- Optimized airflow design with rear-mounted centrifugal blower and perforated top/bottom baffles—ensures laminar circulation and <9% temperature gradient across the full working volume per ISO 17025–recommended validation practices.
Sample Compatibility & Compliance
The 202-3EBS accommodates a broad range of sample formats—including Petri dishes, weighing boats, glassware, metal trays, and polymer molds—within its 225 L internal volume. Its maximum operating temperature of 250 °C satisfies dry-heat sterilization requirements per ISO 15883-1 and USP , while its stable thermal profile supports ASTM E145-compliant drying procedures for gravimetric moisture analysis. The unit complies with IEC 61010-1:2010 safety standards for electrical equipment used in laboratory environments and incorporates dual overtemperature protection (mechanical backup thermostat + electronic cut-off) to prevent thermal runaway. It is compatible with GLP/GMP documentation workflows when paired with external data loggers meeting FDA 21 CFR Part 11 audit-trail requirements.
Software & Data Management
While the base configuration features a standalone digital PID controller with LED display and manual keypad interface, optional RS-485 Modbus RTU connectivity enables integration into centralized lab management systems. When equipped with LabTech’s optional DataBridge™ firmware module (sold separately), users gain access to time-stamped temperature logging, remote setpoint adjustment via Ethernet, and exportable CSV reports compliant with ISO/IEC 17025 clause 7.5.2. All controller variants support password-protected parameter locking, calibration offset adjustment, and sensor drift diagnostics—facilitating routine maintenance and metrological traceability.
Applications
- Pharmaceutical QC labs: Residual solvent removal from active pharmaceutical ingredients (APIs) prior to HPLC analysis; desiccation of reference standards per USP .
- Materials science: Curing of epoxy resins and thermoset composites; thermal aging studies of polymers and coatings.
- Food & agriculture testing: Moisture content determination in cereals, dairy powders, and feedstuffs per AOAC 950.46.
- Clinical microbiology: Dry-heat sterilization of glass pipettes, forceps, and metal instruments where steam autoclaving is unsuitable.
- Environmental labs: Pre-drying of soil/sediment samples before gravimetric total suspended solids (TSS) quantification (EPA Method 160.2).
FAQ
What is the recommended calibration frequency for this oven?
Annual calibration against NIST-traceable reference thermometers is advised; interim verification using Class A PT100 probes every 3 months is recommended for GxP-regulated environments.
Can the oven be validated for IQ/OQ/PQ protocols?
Yes—the unit’s mechanical and electrical design supports full qualification per ASTM E2500 and Annex 15 of the EU GMP Guidelines; documentation templates and sensor mapping kits are available upon request.
Is over-temperature protection certified to a specific standard?
The dual independent overtemperature cutoff system conforms to IEC 61010-1 Clause 11.3 and includes both a self-resetting bimetallic thermostat and a non-resettable thermal fuse rated at 270 °C.
Does the stainless-steel chamber meet food-grade or pharmaceutical-grade surface finish requirements?
The interior surface finish is Ra ≤ 0.8 µm (electropolished equivalent), satisfying ASME BPE-2022 criteria for non-porous, cleanable surfaces in regulated manufacturing processes.
Are spare parts and service manuals available internationally?
Yes—LabTech provides global technical support, OEM replacement heaters, PID modules, door gaskets, and comprehensive English-language service documentation through authorized regional partners.
