Brookfield BAT Series Electric Constant Temperature Incubators

Overview

The Brookfield BAT Series Electric Constant Temperature Incubators are precision-engineered laboratory incubation systems designed for reliable, repeatable thermal control in microbiological culture, cell maintenance, enzyme assays, and general biological storage applications. Utilizing forced horizontal airflow and digital PID temperature regulation, these incubators maintain stable thermal environments across a wide operational range—from ambient +5°C up to 65°C—with minimal overshoot and rapid recovery after door opening. The system’s core architecture integrates a high-stability PT100 platinum resistance thermometer, low-self-heating sensor design, and microprocessor-based feedback loop to ensure consistent thermal performance compliant with routine GLP and ISO 17025-aligned laboratory workflows.

Key Features

• Digital color LCD controller with real-time parameter display, supporting both time-independent constant-temperature operation and programmable timed cycles (0–9999 minutes or 0–999 hours)
• PID-controlled heating system engineered for precision and stability—minimizes temperature overshoot and ensures rapid equilibration
• Horizontal forced-air convection system with three-speed centrifugal fan, optimized for uniform heat distribution and shortest possible temperature recovery post-access
• Double-layer tempered glass observation window with anti-fog coating for continuous visual monitoring without compromising thermal integrity
• Interior chamber constructed from mirror-finish stainless steel with radius-corner geometry for seamless cleaning and reduced microbial retention
• High-compression silicone door gasket combined with isolated hinge mechanism and mechanical latching handle to guarantee long-term sealing integrity
• Adjustable stainless steel shelving (2–3 levels depending on model), allowing flexible vertical spacing to accommodate flasks, Petri dishes, multiwell plates, or custom vessels
• Integrated over-temperature safety cutoff with simultaneous audible and visual alarm—compliant with IEC 61010-1 requirements for laboratory equipment safety

Sample Compatibility & Compliance

The BAT Series accommodates standard microbiological and cellular culture formats—including T-flasks, roller bottles, Petri dishes, and multiwell plates—across all volume variants (40 L to 300 L). Its interior geometry supports unobstructed airflow around stacked or staggered samples, minimizing localized thermal gradients. The incubators meet essential functional criteria outlined in ISO 20387 (Biobanking), ASTM E154 (Standard Specification for Laboratory Incubators), and USP (Biological Indicators and Sterility Assurance). While not certified for medical device manufacturing under FDA 21 CFR Part 820, the units support audit-ready documentation when integrated with optional RS485/USB data logging modules that provide timestamped temperature records traceable to NIST-traceable calibration standards.

Software & Data Management

Equipped with an embedded microcontroller architecture, the BAT Series supports optional serial communication interfaces (RS485 or USB) for integration into centralized environmental monitoring networks. When connected to compatible third-party software or LabVantage/LIMS platforms, users can configure automated data export, generate PDF/CSV temperature logs, and enforce user-access controls aligned with FDA 21 CFR Part 11 requirements—including electronic signatures, audit trails, and data immutability safeguards. Firmware updates are performed via secure USB transfer, ensuring continued compliance with evolving data integrity expectations in regulated life science environments.

Applications

• Maintenance of bacterial, fungal, and mammalian cell lines at physiological temperatures (e.g., 37°C for human cells, 30°C for yeast cultures)
• Enzymatic reaction incubation where precise thermal stability directly impacts kinetic reproducibility
• Environmental stress testing of biologics and excipients during formulation development
• Quality control incubation for sterility testing per USP , EP 2.6.1, and JP 4.07 protocols
• Long-term sample conditioning prior to downstream analysis (e.g., PCR template preparation, ELISA plate coating)
• Teaching laboratory use in undergraduate microbiology and molecular biology curricula

FAQ

What is the recommended calibration interval for the PT100 sensor?
Annual verification against a NIST-traceable reference thermometer is advised; internal sensor drift remains below ±0.05°C/year under normal operating conditions.
Can the incubator be used for CO₂-sensitive applications?
No—this is a non-CO₂, electric-heating-only incubator; it lacks gas blending, humidity control, or CO₂ concentration monitoring capabilities.
Is remote monitoring supported out-of-the-box?
Remote functionality requires optional RS485 or USB interface hardware and compatible host software; no built-in Wi-Fi or Ethernet module is included.
How does the horizontal airflow design improve temperature uniformity compared to vertical convection?
Horizontal laminar flow minimizes thermal stratification by directing heated air uniformly across shelf surfaces—critical for multi-level experiments where vertical gradients would otherwise compromise inter-shelf consistency.
Are replacement shelves and gaskets available as spare parts?
Yes—Brookfield offers OEM-certified stainless steel shelves, silicone door gaskets, and fan assemblies with documented shelf-life and material certifications (RoHS, REACH).
