Brookfield BAT2/6/16-DH Portable Electric Constant-Temperature Incubator

Overview

The Brookfield BAT2/6/16-DH Portable Electric Constant-Temperature Incubator is a compact, field-deployable thermal environment system engineered for precise, stable temperature maintenance in life science applications where mobility and reliability are critical. Designed around the fundamental principle of convective heat transfer augmented by uniform radiant heating, the incubator utilizes an integrated PTC (positive temperature coefficient) electric heating film embedded within the cavity wall structure—ensuring rapid thermal response and minimal thermal gradient across the working volume. Its forced-air circulation system, combined with a streamlined internal geometry featuring rounded stainless-steel corners and smooth mirror-finish surfaces, promotes laminar airflow distribution and eliminates stagnant zones. The unit operates exclusively within the biologically relevant range of RT+5°C to 45°C—a specification aligned with ISO 13408-1 (aseptic processing), USP , and common microbiological culture protocols requiring controlled mesophilic conditions.

Key Features

• Digital PID temperature control algorithm with real-time LCD interface enabling setpoint definition, run-time monitoring, and deviation tracking—optimized to suppress overshoot and stabilize at target temperature within ≤15 minutes after power-on.
• High-stability PT100 Class A sensor (IEC 60751) mounted at chamber center, offering <2 s response time to step-change inputs and self-heating error <0.05°C under nominal load.
• One-piece laser-welded outer chassis with electrostatic powder coating; interior constructed from electropolished 304 stainless steel with radius-curved corners (R ≥15 mm) to support ISO 14644-1 Class 5 cleanroom-compatible cleaning protocols.
• Magnetic door seal with dual-lip silicone gasket ensures air-tight closure (leak rate 30% versus conventional foam seals.
• Over-temperature safety cutoff circuit independently monitored by redundant hardware threshold (set at 47.5°C), triggering audible alarm and automatic heater deactivation without software dependency.

Sample Compatibility & Compliance

The BAT series accommodates standard microbiological vessels including Petri dishes (up to 150 mm diameter), test tubes (16 × 150 mm), microcentrifuge tube racks, and small-volume bioreactor cartridges. Its 2–16 L working volumes meet ASTM E2925-22 requirements for portable incubation validation in point-of-care diagnostics and field-based environmental sampling. All models comply with IEC 61010-1:2010 for laboratory electrical equipment safety, and their thermal performance data—including uniformity (±1.0°C at 37°C), fluctuation (±0.5°C), and accuracy (±0.1°C)—are traceable to NIM (National Institute of Metrology, China) certified reference standards. While not intrinsically rated for GLP/GMP production environments, the incubators support audit-ready documentation when paired with external calibrated loggers (e.g., Vaisala viewLinc or DeltaTRAK FlashPaq) meeting FDA 21 CFR Part 11 data integrity criteria.

Software & Data Management

The BAT-DH series operates as a standalone instrument with no embedded firmware-based data logging. However, its analog voltage output (0–5 V DC proportional to chamber temperature) enables integration with third-party SCADA systems, programmable logic controllers (PLCs), or USB-connected data acquisition modules (e.g., NI USB-TC01). Users may configure continuous recording intervals (1 s to 60 min resolution) and export CSV-formatted datasets compatible with JMP, MATLAB, or LabArchives ELN platforms. For regulated workflows, optional external validation kits—including thermocouple mapping probes (ASTM E2251-compliant) and IQ/OQ documentation templates—are available through authorized Boante distributors.

Applications

• Field-deployable bacterial culture incubation during water quality surveillance (EPA Method 1603/1681), foodborne pathogen screening (ISO 6579-1), and clinical specimen transport conditioning.
• Short-term enzyme activity assays requiring strict thermal stability (e.g., Taq polymerase pre-incubation prior to PCR setup).
• Cell viability assessment in resource-limited settings, including peripheral blood mononuclear cell (PBMC) storage at 37°C during transit to central labs.
• Calibration verification of handheld thermometers and infrared thermal imagers using NIST-traceable reference sources placed inside the chamber.
• Accelerated stability testing of diagnostic reagents under controlled sub-ambient and elevated temperatures per ICH Q1A(R2) guidelines.

FAQ

Is this incubator suitable for CO₂-dependent cell culture?
No. The BAT-DH series maintains only thermal control and lacks gas regulation capability. It is intended for non-CO₂-requiring applications such as bacterial growth, enzyme kinetics, or ambient-air-stable reagent incubation.
Can the unit be operated in a moving vehicle?
Yes—mechanical shock resistance has been validated per MIL-STD-810G Method 516.6 (transit vibration profile). Optional vehicle-mount brackets and 12/24 V DC power adapters (sold separately) enable secure installation in mobile laboratories.
What is the maximum allowable ambient operating temperature?
The device is rated for ambient conditions between 15°C and 35°C and relative humidity ≤80% non-condensing. Operation above 35°C ambient may impair cooling capacity and compromise uniformity specifications.
Does the incubator include a calibration certificate?
Units ship with a factory-as-tested report (including chamber center-point verification at 25°C, 37°C, and 42°C). Full UKAS/NIST-traceable calibration certificates require third-party service engagement.
How often should the PT100 sensor be recalibrated?
Annual recalibration is recommended under routine use. In high-frequency field deployment (>10 cycles/week), verification against a reference thermometer every 90 days is advised per ISO/IEC 17025:2017 clause 7.7.
