BOXUN BG-160 Water-Jacketed Constant Temperature Incubator

Overview

The BOXUN BG-160 Water-Jacketed Constant Temperature Incubator is an engineered solution for stable, uniform, and contamination-resistant thermal environments in life science laboratories. Unlike forced-air incubators, the BG-160 employs a water-jacketed heating architecture—where heated water circulates within a sealed outer chamber surrounding the inner workspace—delivering superior thermal inertia, minimal temperature overshoot, and exceptional stability during prolonged operation. This design inherently dampens external ambient fluctuations and ensures consistent conditions critical for sensitive biological processes including mammalian cell culture, microbial growth kinetics, BOD testing per ISO 5815-1, plant tissue culture initiation, and embryonic development studies. Its robust construction—featuring a cold-rolled steel exterior with electrostatic epoxy coating and a mirror-finish 304 stainless steel interior—meets fundamental requirements for cleanroom-compatible equipment under GLP-compliant workflows.

Key Features

• Water-jacketed thermal system with independent left/right/bottom heating zones for precise heat distribution and minimized vertical gradients
• Microprocessor-based PID temperature controller with LCD interface, supporting real-time display of setpoint, actual temperature, elapsed time, and alarm status
• Three-tier adjustable stainless steel shelving with reinforced load capacity; all trays are removable and autoclavable
• Double-sealed access door: tempered glass front panel integrated with dual-layer silicone gasketing to maintain internal humidity and prevent condensation-induced thermal bridging
• Low-noise axial fan with adaptive speed modulation—automatically optimized based on thermal load and setpoint deviation to sustain uniform air circulation without disturbing delicate cultures
• Programmable operation mode: up to 10 temperature/time segments across 100 total cycles, enabling unattended multi-stage protocols (e.g., stratification → germination → hardening)
• RS-485 serial interface compliant with Modbus RTU protocol for integration into centralized lab monitoring systems or SCADA platforms
• Non-volatile memory retention: preserves user-defined parameters—including program sequences, alarms, and calibration offsets—during power interruption or system reset

Sample Compatibility & Compliance

The BG-160 accommodates standard laboratory vessels including Petri dishes (up to 150 mm), multi-well plates (6–96-well), Erlenmeyer flasks (≤2 L), and tissue culture roller bottles. Its water-jacketed configuration minimizes relative humidity loss—maintaining >85% RH at 37°C without supplemental humidification—making it suitable for non-CO₂-dependent applications where moisture-sensitive media (e.g., agar-based plant regeneration media or anaerobic enrichment broths) must remain intact. The unit complies with IEC 61010-1:2010 safety standards for electrical equipment used in laboratory environments and supports audit-ready documentation for ISO/IEC 17025-accredited testing labs. While not certified for medical device manufacturing under ISO 13485, its design principles align with GMP Annex 11 data integrity expectations when paired with validated PC monitoring software and electronic log archiving.

Software & Data Management

The BG-160 supports optional PC-based supervision via RS-485-to-USB conversion and BOXUN’s proprietary LabLink™ software (Windows 10/11 compatible). This application enables remote parameter configuration, real-time graphing of temperature profiles, automated CSV export of timestamped readings at user-defined intervals (1 s–60 min), and configurable alarm notifications via email or SMS when integrated with the optional GPRS module. All logged data include operator ID, event timestamps, and change history—supporting ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) for regulatory submissions. Thermal printer integration provides hard-copy traceability of critical runs, including trend curves and pass/fail indicators against predefined acceptance criteria.

Applications

• Microbiological assays requiring strict thermal consistency: bacterial enumeration (ISO 4833-1), yeast/mold counts (ISO 21527-1), and antibiotic susceptibility testing (CLSI M07)
• Environmental monitoring: biochemical oxygen demand (BOD₅) determination per ASTM D5210 and ISO 5815-1
• Botanical research: seed germination trials (ISTA Rules), callus induction, and micropropagation under controlled photoperiod-agnostic conditions
• Veterinary and aquaculture labs: fish egg incubation, insect rearing (e.g., Drosophila developmental staging), and small-mammal neonatal support
• Pharmaceutical QC: stability testing of excipients and non-sterile dosage forms under long-term storage conditions (ICH Q1A)

FAQ

What is the purpose of the water jacket in this incubator?
The water jacket serves as a high-thermal-mass buffer zone that significantly reduces temperature variability caused by door openings, ambient drafts, or power cycling—enabling ±0.2°C fluctuation and ±0.5°C uniformity across the entire chamber volume.
Can the BG-160 be used for CO₂-dependent cell culture?
No—it lacks CO₂ regulation, gas-tight sealing, and humidification control required for mammalian monolayer maintenance; it is intended for non-CO₂ applications such as bacterial culture, fungal growth, or plant explant development.
Is calibration traceable to national standards?
Yes—optional NIST-traceable temperature calibration certificates are available upon request, covering probe verification at three points (25°C, 37°C, 55°C) with uncertainty reporting per ISO/IEC 17025.
How does the auto-restart function handle power failures?
Upon restoration of AC power, the incubator resumes the last active program segment using stored parameters—including remaining time, target temperature, and fan speed—without manual intervention.
What maintenance is required for the water jacket?
Deionized or distilled water must be refilled every 6–12 months depending on ambient evaporation rate; periodic inspection of jacket integrity and silicone gasket condition is recommended annually.
