Boante BAT-Series Benchtop Forced-Air Constant-Temperature Drying Oven

Overview

The Boante BAT-Series Benchtop Forced-Air Constant-Temperature Drying Oven is an engineered solution for precise, repeatable thermal processing in research laboratories, quality control environments, and industrial R&D settings. Utilizing forced-convection airflow architecture—where a rear-mounted centrifugal blower delivers horizontal, laminar air movement across the chamber—the oven ensures rapid thermal equilibration and high spatial uniformity. Its operational principle relies on closed-loop temperature regulation via a microprocessor-based PID controller, continuously modulating heater output in response to real-time feedback from a calibrated PT100 sensor. This architecture minimizes overshoot and stabilizes chamber conditions within ±1°C fluctuation and ±3% uniformity relative to setpoint—performance metrics validated under steady-state conditions per GB/T 5170.2–2017. The oven operates across a broad usable range from ambient +10°C to 250°C, making it suitable for moisture removal, pre-weighing sample conditioning, polymer curing validation, and residual solvent evaporation protocols.

Key Features

• Mirror-finish AISI 304 stainless steel interior chamber with seamless, radius-corner construction—resistant to corrosion, non-porous, and compliant with cleaning validation requirements for regulated labs.
• Laser-cut and welded outer chassis with electrostatic powder-coated finish—enhancing structural rigidity and long-term dimensional stability.
• Triple-layer sealing system: high-temperature silicone door gasket, isolation-type hinge design, and dual-point latching mechanism—ensuring thermal integrity and minimizing heat leakage during extended operation.
• Double-pane tempered glass observation window with low-emissivity coating—providing clear visual monitoring while reducing surface condensation and maintaining external surface temperature below 45°C at 200°C internal setpoint.
• Three-speed adjustable blower control—enabling optimization of airflow velocity for delicate samples (e.g., thin-film coatings) or high-mass loads requiring aggressive convective transfer.
• Configurable shelving: two (or three in BAT210-TGF) removable, height-adjustable stainless steel shelves—supporting load distribution flexibility and accessibility for ISO/IEC 17025-compliant calibration verification procedures.

Sample Compatibility & Compliance

The BAT-Series accommodates standard laboratory vessels including Petri dishes, weighing boats, crucibles, glass beakers, and aluminum sample pans—compatible with ASTM D2240 (Shore hardness preconditioning), ISO 293 (thermoplastic compression molding), and USP (container drying prior to extractables testing). Chamber geometry and airflow profile have been validated for ≤5% temperature deviation across full load conditions (per ICH Q5C stability protocol guidelines). All electrical components conform to GB 4793.1–2019 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use). Optional RS485 interface supports Modbus RTU communication for integration into centralized facility monitoring systems compliant with FDA 21 CFR Part 11 audit trail requirements when paired with validated data acquisition software.

Software & Data Management

Standard configuration includes an embedded 4.3-inch color LCD controller with intuitive icon-driven navigation, supporting both time-based (0–9999 min / 0–999 h) and temperature-based termination logic. Optional upgrades include a 5-inch capacitive touch controller with USB data export (CSV format), real-time graphing, and password-protected parameter locking—enabling traceable operation logs aligned with GLP/GMP Annex 11 expectations. When connected via RS485 to a host PC running Boante’s certified TempLog Pro v3.2 software, users can configure multi-step ramp-hold profiles, generate PDF reports with digital signatures, and archive raw sensor data with timestamped metadata—including ambient temperature compensation records. Remote monitoring via WeChat Mini Program provides status alerts and historical trend access without compromising network security boundaries.

Applications

• Moisture content determination per AOAC 950.46 and ISO 5528 for food, pharmaceutical excipients, and soil samples.
• Pre-drying of filter membranes prior to gravimetric particulate analysis (EPA Method 160.1).
• Thermal stabilization of reference standards before calibration of analytical balances (OIML R76).
• Curing support for epoxy-coated test coupons used in ASTM D4541 pull-off adhesion testing.
• Desiccation of hygroscopic reagents (e.g., lithium aluminum hydride, phosphorus pentoxide) under controlled inert-atmosphere prep conditions.
• Accelerated aging studies for packaging materials per ASTM F1980, where precise 40°C/75% RH preconditioning precedes peel strength evaluation.

FAQ

What is the maximum allowable load volume for uniform temperature distribution?
Uniformity specifications assume ≤70% chamber volume occupancy; exceeding this threshold may degrade performance beyond ±3% uniformity—validated per GB/T 5170.2–2017 Annex B.
Is the oven suitable for use with flammable solvents?
No. This model lacks explosion-proof certification (e.g., ATEX or UL 1203) and is not rated for Class I, Division 1 hazardous locations.
Can the PT100 sensor be recalibrated in-house?
Yes—sensor offset adjustment is accessible via service mode using a NIST-traceable dry-block calibrator; full calibration requires factory service or ISO/IEC 17025-accredited third-party lab.
Does the USB data export include timestamps synchronized to UTC?
Yes—when connected to a PC with internet time sync enabled, TempLog Pro v3.2 embeds ISO 8601-compliant UTC timestamps in all exported CSV files.
What maintenance intervals are recommended for the blower motor?
Inspection every 500 operating hours; lubrication-free sleeve bearings require no scheduled greasing but should be checked for axial play and abnormal acoustic emission during routine GLP audits.
