Boante BAT-Series Dual-Zone Forced-Air Constant-Temperature Drying Oven

Overview

The Boante BAT-Series Dual-Zone Forced-Air Constant-Temperature Drying Oven is an engineered solution for laboratories requiring simultaneous yet independent thermal processing of multiple sample batches under tightly controlled conditions. Unlike conventional single-chamber ovens, this instrument integrates two physically separated, thermally isolated workspaces within a unified chassis—each equipped with dedicated heating elements, PT100 resistance temperature detectors (RTDs), and independent microprocessor-based PID controllers. The system operates on the principle of forced convection, utilizing a rear-mounted centrifugal blower to generate horizontal airflow across the chamber volume, ensuring rapid thermal equilibration and minimizing recovery time after door opening. Designed for routine drying, curing, sterilization pre-treatment, moisture content determination, and thermal stability assessment, the BAT-Series complies with fundamental laboratory environmental control requirements per ISO/IEC 17025:2017 clause 6.4 (environmental conditions) and supports GLP-compliant workflows when configured with data logging and audit-trail-capable controllers.

Key Features

• Dual independent chambers enable concurrent operation at different temperatures and timing profiles—eliminating cross-contamination risk and improving throughput efficiency.
• High-precision PT100 sensors with low self-heating effect ensure fast dynamic response (<5 s for 90% step response) and long-term drift stability (<0.1 °C/year).
• LCD blue-backlit controller displays real-time chamber temperature, setpoint, elapsed time, and remaining time; supports both constant-temperature and programmable timer modes.
• Mirror-finish 304 stainless steel interior with radius-corner construction minimizes particle retention and facilitates cleaning validation per USP guidelines.
• Double-layer tempered glass observation window maintains thermal integrity while enabling non-intrusive visual monitoring without compromising chamber uniformity.
• Isolated hinge design and compression-type silicone gasket provide >95% sealing efficiency at 250 °C, verified per ASTM E145-22 Annex A3 (oven leakage test methodology).
• Over-temperature protection circuit triggers audible and visual alarm if internal temperature exceeds user-defined safety limit by ≥5 °C.

Sample Compatibility & Compliance

The BAT-Series accommodates standard laboratory ware including Petri dishes, weighing bottles, crucibles, aluminum pans, and glass desiccators. Its dual-zone architecture supports comparative studies—e.g., accelerated aging tests per ICH Q1A(R2), residual solvent evaporation per USP , or polymer curing kinetics analysis. All models meet CE marking requirements for electrical safety (EN 61010-1) and electromagnetic compatibility (EN 61326-1). When equipped with optional RS485 interface and compliant software, the system supports 21 CFR Part 11–aligned electronic recordkeeping—including user authentication, change history, and digital signature capability—for regulated QC/QA environments.

Software & Data Management

Standard configuration includes embedded firmware supporting local parameter storage (≥100 programs), event logging (door open/close, alarm trigger, temperature deviation), and real-time display of deviation from setpoint. Optional upgrades include a 5-inch capacitive touchscreen controller with graphical trend visualization, USB mass-storage export of CSV-formatted temperature logs (timestamped at 10-s intervals), and RS485 Modbus RTU protocol for integration into LabVantage, Thermo Fisher SampleManager, or custom SCADA systems. Remote supervision via WeChat Mini-Program enables push notifications for alarm events and remote setpoint adjustment—subject to network-authenticated access control.

Applications

• Moisture loss-on-drying (LOD) assays in pharmaceutical raw material release testing (USP ).
• Pre-drying of filter membranes prior to gravimetric particulate matter analysis (EPA Method 201A).
• Curing of epoxy-coated substrates in materials science R&D.
• Baking of silica gel desiccants and activated carbon carriers in analytical chemistry labs.
• Thermal conditioning of reference standards before calibration of hygrometers or thermocouples.
• Stability chamber qualification support (IQ/OQ documentation packages available upon request).

FAQ

Can both chambers operate at different temperatures simultaneously?
Yes—the upper and lower chambers are fully independent, each with its own temperature sensor, heater, and control loop.
What is the maximum allowable load per shelf?
Each stainless steel shelf supports up to 15 kg uniformly distributed load; total chamber loading must not obstruct airflow paths or exceed 80% volume occupancy.
Is the oven suitable for use with flammable solvents?
No—this is a general-purpose drying oven without explosion-proof certification; use only with non-volatile or low-volatility samples.
How often should the PT100 sensors be calibrated?
Annual calibration against NIST-traceable reference standards is recommended; field verification using dry-block calibrators can be performed quarterly.
Does the USB data logger record timestamps with UTC synchronization?
Yes—when connected to a host PC with internet time sync enabled, the device embeds ISO 8601-formatted timestamps in exported log files.
