Brookfield BAT50/100/150/250-JDH Precision Electric Constant Temperature Incubator

Overview

The Brookfield BAT Series Precision Electric Constant Temperature Incubator is engineered for reliable, reproducible thermal environments in life science laboratories, quality control facilities, and academic research settings. Utilizing a forced horizontal convection airflow system—driven by a centrifugal blower with three adjustable speed levels—the incubator ensures rapid temperature recovery after door opening and exceptional spatial uniformity across the entire working chamber. Its core thermal regulation relies on a high-stability PT100 platinum resistance thermometer coupled with a microprocessor-based digital PID controller, minimizing overshoot and maintaining setpoint stability within ±0.1°C under steady-state conditions. The chamber operates within a practical range of RT+5°C to 65°C, optimized for microbial growth, cell culture maintenance, enzyme assays, and stability testing protocols where precise, drift-free temperature control is critical.

Key Features

• 5-inch full-color capacitive touchscreen interface with real-time parameter display and intuitive navigation
• 30-segment programmable temperature/time profile capability (each segment: 0–9999 minutes duration)
• Mirror-finish stainless-steel interior with seamless, radius-rounded corners for effortless cleaning and contamination control
• Dual-layer insulated observation window with low-emissivity glass and magnetic seal, preserving internal thermal integrity during visual inspection
• Laser-cut, welded outer chassis with electrostatic powder coating for corrosion resistance and structural rigidity
• Adjustable stainless-steel shelf system: fully removable and repositionable to accommodate varied vessel heights and experimental configurations
• Independent over-temperature safety cutoff with simultaneous audible alarm and visual indicator—compliant with IEC 61010-1 requirements for laboratory equipment

Sample Compatibility & Compliance

The BAT series accommodates standard laboratory vessels including Petri dishes, multi-well plates, flasks, and culture tubes without interference from airflow turbulence. Its chamber geometry and horizontal air distribution minimize thermal stratification and convective shear stress on sensitive biological samples. All models meet essential electrical safety standards per IEC 61010-1 and are designed to support GLP-compliant workflows. When equipped with optional RS485 or USB interfaces, the incubator supports audit-trail-capable data logging—enabling traceability aligned with FDA 21 CFR Part 11 principles when integrated into validated systems. The unit is suitable for use in ISO 13485-certified medical device manufacturing environments and ASTM E2874-compliant stability chambers when operated within specified environmental conditions.

Software & Data Management

While the onboard controller provides standalone operation, optional communication modules enable integration into centralized lab monitoring networks. The RS485 interface supports Modbus RTU protocol for bidirectional command exchange with SCADA or LIMS platforms. USB connectivity allows direct export of time-stamped temperature logs (.CSV format) to external storage devices. Firmware supports user-defined calibration offsets and password-protected parameter locking—critical for regulated environments requiring change control documentation. Data retention intervals and sampling frequency (default: 10-second intervals) are configurable via the touch interface, ensuring alignment with internal SOPs and regulatory expectations for environmental monitoring records.

Applications

• Bacterial and fungal culture incubation under CLSI-recommended conditions (e.g., 35°C ±0.5°C for aerobic plate counts)
• Mammalian cell line maintenance at physiological temperatures (37°C ±0.2°C), including CO₂-independent cultures
• Enzyme activity assays requiring strict thermal consistency across replicate runs
• Accelerated stability studies per ICH Q1A(R3) guidelines for pharmaceutical intermediates
• Quality assurance testing of diagnostic reagents and clinical assay kits
• Environmental simulation for material biodegradability assessments (ISO 14855)

FAQ

What is the maximum operating temperature of the BAT series incubators?
The upper temperature limit is 65°C, with stable operation achievable across the full range from ambient +5°C to 65°C.
Does the incubator support validation documentation for GxP environments?
Yes—when configured with optional data logging and used with appropriate IQ/OQ protocols, it supports qualification under GMP, GLP, and ISO 17025 frameworks.
Can multiple incubators be networked for centralized monitoring?
Yes—RS485 daisy-chaining enables up to 32 units on a single bus, compatible with third-party building management or lab infrastructure software.
Is the internal chamber humidity controlled?
No—this is a dry-air constant temperature incubator; humidity control requires separate humidification add-ons or dedicated CO₂/humidity models.
What is the typical temperature recovery time after a 30-second door opening at 37°C?
Under standard test conditions (BAT100-JDH, mid-shelf position), recovery to ±0.3°C of setpoint occurs within ≤3.5 minutes.
