BOXUN BXYC-C Series CO₂-Integrated Stackable Precision Incubator Shaker

Overview

The BOXUN BXYC-C Series CO₂-Integrated Stackable Precision Incubator Shaker is an engineered solution for long-term, high-fidelity cell culture, microbial fermentation, and suspension-based bioprocessing under tightly regulated environmental conditions. Unlike conventional orbital shakers, this system integrates real-time CO₂ concentration control with precise temperature regulation, programmable orbital motion, and multi-layer stackable architecture—enabling laboratory-scale scalability without compromising parameter fidelity. The instrument operates on a dual-control principle: thermal regulation via a high-efficiency refrigeration circuit (featuring imported compressors and intelligent defrost logic), and gaseous environment control via infrared CO₂ sensing and dual-solenoid gas flow modulation. Designed for GLP-compliant workflows, it supports continuous operation across extended durations (up to 999.9 hours per program), making it suitable for mammalian cell expansion, yeast propagation, and recombinant protein expression where pH stability (via CO₂/bicarbonate buffering) and shear-sensitive growth kinetics are critical.

Key Features

• Stackable modular design with top-hinged lid (upper deck) and bottom-hinged access doors (lower decks), optimizing bench space and enabling temporary surface use during loading/unloading.
• Removable shaking platform secured via mechanical latch system—ensures mechanical stability during high-speed operation while facilitating rapid vessel exchange.
• BRIGHT II Intelligent Control System with adaptive parameter compensation based on ambient thermal drift and load-induced thermal inertia.
• 7-inch full-color capacitive touchscreen interface supporting independent control per deck: temperature, speed, orbit diameter, rotation direction (forward/reverse/alternating), timing mode, cycle segmentation, and calendar-based scheduling.
• Programmable logic: up to 5 user-defined protocols, each comprising 30 segments and 99 cycles—enabling complex ramp-and-hold profiles for differentiation studies or fed-batch initiation.
• Dual CO₂ delivery control: fast-fill and slow-fill electromagnetic valves regulate gas flow dynamically to maintain setpoint accuracy (±0.1% CO₂ v/v) while minimizing cylinder consumption.
• Intelligent frost management: adjustable defrost temperature, interval, and duration—prevents ice accumulation in evaporator coils without interrupting incubation integrity.
• Compressor soft-start delay (≥3 min) and servo motor ramp-up algorithm mitigate mechanical stress and prevent liquid splashing during acceleration phases.

Sample Compatibility & Compliance

The BXYC-C accommodates standard culture vessels including Erlenmeyer flasks (50–5000 mL), roller bottles, deep-well plates, and custom bioreactor sleeves. Its stainless-steel, waterproof interior with integrated drainage grooves supports wet-cleaning protocols and prevents cross-contamination from aerosolized biomass. The chamber includes UV germicidal irradiation (254 nm) and LED illumination for visual monitoring without door opening. All electronic subsystems comply with IEC 61010-1 safety standards for laboratory equipment. Data logging meets ALCOA+ principles: timestamps, operator IDs (via optional password protection), and immutable audit trails are embedded in stored records. While not FDA 21 CFR Part 11–certified out-of-box, the system’s firmware architecture supports future validation packages for GMP environments upon IQ/OQ/PQ execution.

Software & Data Management

Internal storage retains ≥150,000 timestamped data points—including real-time temperature, CO₂ concentration, RPM, and alarm events—with automatic time-stamped event logging (e.g., door open, compressor fault, sensor timeout). USB export enables CSV-formatted data transfer for post-acquisition analysis in MATLAB, Python (Pandas), or LIMS-integrated platforms. Historical curve navigation supports temporal jump-to-point functionality: users may select any timestamp to overlay measured vs. setpoint traces for temperature, CO₂, and speed. Optional remote monitoring software provides centralized oversight of multiple BXYC-C units via Ethernet/Wi-Fi, displaying live parameters, historical trends, and predictive maintenance alerts (e.g., compressor runtime thresholds, CO₂ cylinder depletion estimates).

Applications

• Mammalian cell culture (CHO, HEK293) requiring stable 5% CO₂ and 37°C with orbital agitation to enhance mass transfer and prevent sedimentation.
• Microbial fermentation of E. coli, S. cerevisiae, or P. pastoris under controlled pH (via CO₂-mediated buffering) and oxygen transfer optimization.
• Stem cell expansion protocols demanding low-shear, humidity-stabilized environments—enhanced by optional RH module (ambient–95% RH, ±5% RH accuracy).
• Photobioreactor development using optional 6-level adjustable illumination (0–16,000 lux), enabling circadian rhythm studies or light-dependent metabolic engineering.
• Biobanking and cryopreservation prep workflows where consistent pre-thaw agitation and CO₂ equilibration improve viability recovery rates.

FAQ

What CO₂ sensing technology is used, and what is its measurement range and accuracy?
The system employs a factory-calibrated NDIR (non-dispersive infrared) CO₂ sensor with a measurement range of 0–20% v/v and typical accuracy of ±0.1% v/v within the 0–10% operating band.
Can the shaker operate without CO₂ supply?
Yes—the CO₂ control loop is fully decoupled from temperature and agitation systems; the unit functions as a high-precision incubator shaker in ambient-air mode.
Is humidity control included as standard?
No—humidity regulation is available only as an optional add-on module (BXYC-HUM), providing active humidification from ambient RH up to 95% RH with ±5% RH control precision.
How does the system handle power interruptions?
It features auto-restart capability with configurable resume behavior: users may select “resume from last state”, “restart from beginning”, or “hold until manual intervention” after power restoration.
What maintenance intervals are recommended for long-term reliability?
Compressor oil inspection every 24 months; CO₂ sensor recalibration annually; UV lamp replacement every 12 months (or after 8,000 hours); and routine cleaning of condensate drain channels per ISO 14644-1 Class 7 cleanroom-compatible protocols.
