Boante BAT20/50/90/210-DZF Vacuum Drying Oven

Overview

The Boante BAT Series Vacuum Drying Ovens (BAT20-DZF, BAT50-DZF, BAT90-DZF, and BAT210-DZF) are precision-engineered laboratory instruments designed for moisture removal, solvent evaporation, heat-sensitive sample drying, and stabilization of hygroscopic or oxidation-prone materials under reduced pressure. Operating on the principle of vacuum-assisted thermal desorption, these ovens lower the boiling point of volatile substances by reducing ambient pressure—enabling efficient drying at lower temperatures than conventional convection ovens. This minimizes thermal degradation, preserves structural integrity of biological samples, pharmaceutical intermediates, polymers, and electronic components, and ensures reproducible residual moisture content in quality-critical applications. Each model complies with fundamental design requirements outlined in ISO 17025-accredited calibration practices and supports GLP-compliant workflows through traceable temperature control and optional audit-ready data logging.

Key Features

• Mirror-finish 304 stainless steel chamber with seamless laser-welded construction and radius-rounded corners for optimal cleanability and corrosion resistance.
• High-efficiency vacuum system achieving ≤133 Pa ultimate pressure, compatible with standard two-stage rotary vane vacuum pumps (not included).
• Microprocessor-based PID temperature controller with blue-backlit LCD display, supporting both setpoint and programmable time-based operation (0–9999 minutes or 0–999 hours).
• PT100 platinum resistance thermometer with fast thermal response (<3 s to 90% step change) and low self-heating error (<0.05°C), ensuring accurate real-time feedback control.
• Preheated air circulation design: heated air is mixed and directed into the chamber via a dedicated preheat cavity, enhancing thermal homogeneity and shortening ramp-up time.
• Tempered safety glass observation door with adjustable compression mechanism and integrally molded silicone gasket for reliable vacuum sealing over extended cycles.
• Aluminum alloy shelf plates with high thermal conductivity and uniform heat distribution across load-bearing surfaces.
• Dual-stage safety architecture: independent mechanical over-temperature cut-off switch plus electronic alarm with audible buzzer and visual LED indicator.

Sample Compatibility & Compliance

The BAT-DZF series accommodates a broad range of sample formats including Petri dishes, weighing bottles, crucibles, glass vials, and custom trays up to the maximum internal dimensions (e.g., 450 × 450 × 450 mm for BAT90-DZF). It is routinely deployed in pharmaceutical stability testing (aligned with ICH Q1A–Q1E guidelines), moisture content analysis per USP , residual solvent determination (ICH Q3C), and pre-weighing preparation for gravimetric analysis (ASTM E1218, ISO 554). Chamber material meets FDA 21 CFR 178.3570 requirements for indirect food contact surfaces. Optional RS485 interface enables integration into centralized lab monitoring systems compliant with 21 CFR Part 11 when paired with validated software platforms.

Software & Data Management

Standard configuration includes local parameter storage and real-time display of chamber temperature, elapsed time, and vacuum status. Optional upgrades support regulatory-grade data integrity: the 5-inch touchscreen controller provides multi-segment ramp-soak programming, password-protected user levels, and timestamped event logging. USB export functionality allows CSV-formatted temperature/vacuum history files for offline review. When connected via RS485 to a validated PC-based acquisition system, the oven supports automated data capture with electronic signatures, audit trails, and report generation—fully aligned with GMP Annex 11 and ALCOA+ principles.

Applications

• Drying heat-labile APIs and excipients without decomposition or polymorphic transition.
• Removing residual solvents from coated tablets, film-coated granules, or lyophilized formulations.
• Conditioning reference standards and certified reference materials (CRMs) prior to calibration or certification.
• Dehydrating soil, sediment, or sludge samples for total solids determination (EPA Method 1684).
• Outgassing of optical components, MEMS devices, and vacuum-compatible sensors prior to packaging.
• Accelerated aging studies requiring controlled low-humidity environments under inert gas purging (with optional N₂ inlet port).

FAQ

What is the maximum operating temperature and corresponding accuracy specification?
The unit is rated for continuous operation from ambient +10°C to 250°C, with temperature fluctuation maintained within ±1°C and uniformity within ±3% of the setpoint across the working volume.
Is the vacuum system integrated or external?
The oven is equipped with a vacuum port (KF16 or G1/4″ internal thread, depending on model) and requires an externally connected vacuum pump; no built-in pump is provided.
Can multiple temperature setpoints be programmed for unattended operation?
Yes—the optional touchscreen controller supports up to 32 segments of ramp-and-soak profiles, enabling complex thermal cycling protocols.
Does the device support validation documentation (IQ/OQ/PQ)?
While the base unit does not ship with formal validation protocols, all models include factory calibration certificates for temperature and vacuum sensors, and optional IQ/OQ templates are available upon request for GxP-regulated environments.
What maintenance is required for long-term vacuum integrity?
Routine inspection of the silicone door gasket for compression set or cracking is recommended every 6 months; replacement gaskets are available as spare parts with traceable lot numbers.
