Boxun BSD-100 Orbital Shaking Incubator

Overview

The Boxun BSD-100 Orbital Shaking Incubator is an integrated environmental chamber engineered for precise temperature-controlled cultivation of microbial, cellular, and biochemical samples under dynamic agitation conditions. It combines a microprocessor-regulated thermostatic chamber with a robust orbital shaking platform—enabling simultaneous control of thermal environment and mechanical stimulation essential for aerobic cell growth, suspension culture expansion, enzyme kinetics studies, and BOD (Biochemical Oxygen Demand) assays. The unit operates on a dual-function principle: thermoregulation via a sealed, high-efficiency compressor-based refrigeration system using R134a (CFC-free), and motion control through a brushless DC motor driving a balanced eccentric drive mechanism. Its chamber design adheres to standard incubator performance benchmarks defined in ISO 8570-1 (incubators for microbiology) and supports routine validation per ASTM E2500-13 (verification of laboratory equipment). Intended for use in regulated life science laboratories, the BSD-100 delivers stable operation across its full 0–60°C range, with documented uniformity of ±1°C at 37°C—a critical threshold for mammalian and bacterial culture fidelity.

Key Features

• Microprocessor-based PID temperature control with 0.1°C resolution and ±0.5°C stability; real-time LCD display showing setpoint, actual temperature, elapsed time, and remaining timer duration
• Orbital shaking platform with continuously adjustable speed (0–220 rpm) and fixed 20 mm orbit diameter; optional reciprocating mode (0–300 cycles/min, 30 mm stroke) for specialized suspension protocols
• Integrated refrigeration architecture featuring an internationally certified hermetic compressor, optimized copper-aluminum evaporator, and passive auto-defrost cycle that eliminates thermal perturbation during long-term runs
• Double-layer insulated chamber with cold-rolled steel exterior (electrostatically powder-coated), mirror-finish 304 stainless steel interior, and one removable/adjustable stainless steel shelf
• Dual air management: programmable independent fresh-air intake (on/off controllable) and rear-mounted ventilation ducts ensuring consistent O₂ replenishment without compromising temperature homogeneity
• Comprehensive safety suite including over-temperature cut-off, power-failure parameter retention, automatic restart with recovery logic, and mechanical door lock compliant with IEC 61010-1 Class II requirements
• RS-485 serial interface supporting Modbus RTU protocol for integration into centralized lab monitoring systems or third-party data loggers

Sample Compatibility & Compliance

The BSD-100 accommodates standard laboratory vessels—including Erlenmeyer flasks (up to 2 L), test tubes, multi-well plates, and culture bags—secured on its 370 × 300 × 200 mm oscillating platform. Its 100 L internal volume permits concurrent processing of multiple sample sets while maintaining spatial uniformity. The absence of humidity control makes it suitable for applications where condensation must be avoided—such as antibiotic susceptibility testing, phage propagation, and anaerobic pre-cultures requiring gas-tight sealing. The device conforms to electromagnetic compatibility (EMC) standards IEC 61326-1 and electrical safety standard IEC 61010-1. While not certified for medical device manufacturing, its operational repeatability and audit-ready parameter logging (via optional RS-485 export) align with GLP documentation expectations for academic, environmental, and QC labs performing EPA Method 521 (BOD), ISO 6222 (coliform enumeration), or USP microbial limits testing.

Software & Data Management

The BSD-100 embeds firmware supporting up to 10 programmable segments with 99 cycles per segment—enabling complex ramp-hold-cool sequences for synchronized growth-phase experiments. All settings—including temperature setpoints, shake profiles, timers, and alarm thresholds—are stored in non-volatile memory and retained during mains interruption. The RS-485 port allows bidirectional communication: users may configure parameters remotely or stream timestamped temperature/shake-speed logs at user-defined intervals (e.g., every 30 sec) to external PCs running terminal emulation or custom LabVIEW/Python acquisition scripts. Optional accessories include a thermal printer module (supporting trend curve output) and GPRS-enabled SMS alert hardware for unscheduled deviation notifications (e.g., door open, temp excursion >±2°C). Audit trail generation is achievable via external SCADA systems compliant with FDA 21 CFR Part 11 when paired with appropriate electronic signature middleware.

Applications

• Aerobic microbial culture for water quality assessment (e.g., BOD₅, coliform enumeration per APHA Standard Methods)
• Suspension-based cell line expansion (CHO, HEK293) prior to transfection or bioreactor inoculation
• Enzyme activity profiling under controlled thermal-agitation conditions
• Antibiotic degradation kinetics and metabolite formation studies in liquid media
• Seed germination and plant tissue culture under circadian-mimicking agitation regimes
• Quality control of probiotic formulations and starter cultures in food/pharma manufacturing environments

FAQ

Does the BSD-100 support humidity control?
No. This model is a dry-shake incubator; humidity regulation is not implemented. For humidified applications, consider Boxun’s BH series CO₂/humidity incubators.
What is the maximum flask size supported on the shaker platform?
Standard configuration accommodates up to two 2 L Erlenmeyer flasks (with proper clamping). Larger loads require verification of center-of-gravity balance and are not covered under warranty.
Is the RS-485 interface compatible with common lab data systems?
Yes—it implements Modbus RTU protocol at 9600 baud, 8N1, and is interoperable with LabVIEW, MATLAB Serial, and most industrial SCADA platforms.
Can the unit operate continuously for 7+ days?
Yes. The auto-defrost system, thermal overload protection, and redundant fan control enable unattended operation exceeding 168 hours when validated per user-defined SOPs.
Are calibration certificates available?
Factory calibration reports (traceable to NIM China) are provided with each unit. UKAS/NIST-traceable third-party calibration services can be arranged through authorized Boxun service partners.
