Boxun BSD-TF270 Benchtop Incubated Orbital Shaker

Overview

The Boxun BSD-TF270 Benchtop Incubated Orbital Shaker is an engineered platform for precise, reproducible cell culture, microbial growth, solubility testing, and biochemical incubation under controlled temperature and agitation conditions. Utilizing a single-axis orbital drive mechanism with continuously adjustable amplitude and frequency, the system delivers stable, low-shear motion optimized for oxygen transfer efficiency in suspension cultures—critical for aerobic fermentation, E. coli expression, yeast propagation, and mammalian cell expansion. Its integrated P.I.D. microprocessor-based environmental scanning controller maintains thermal stability across the full 5–60 °C range, with ±0.1 °C setpoint accuracy and ±1 °C uniformity at 37 °C (measured per ISO 17025-aligned validation protocols). Designed for routine QC labs, academic core facilities, and pilot-scale bioprocess development, the BSD-TF270 meets fundamental requirements for GLP-compliant shaker operation when paired with documented calibration and maintenance records.

Key Features

• Single-axis orbital drive architecture with continuous amplitude adjustment—enabling fine-tuned optimization of dissolved oxygen (DO) transfer without mechanical gear shifts or discrete settings
• DC brushless motor with constant torque output across 25–240 rpm; eliminates carbon wear, reduces electromagnetic interference, and ensures stable speed under ±10% AC line voltage fluctuation
• P.I.D. temperature control algorithm with real-time environmental scanning—compensates for door openings, ambient drift, and load mass variations to sustain chamber uniformity
• LCD backlit display showing simultaneous readouts of setpoint temperature, actual chamber temperature, oscillation speed, elapsed time, and remaining timer duration
• Programmable timer with 0–999-hour range and auto-restart function—supports unattended overnight or multi-day incubations with power-loss recovery
• Over-temperature cut-off with independent thermal fuse and audible/visual alarm—complies with IEC 61010-1 safety requirements for laboratory equipment
• Lockable parameter interface with password protection—prevents unauthorized modification of critical operational settings during shared-lab use

Sample Compatibility & Compliance

The BSD-TF270 accommodates standard microbiological and cell culture vessels on its 440 × 420 mm stainless-steel platform, including flasks (50–1000 mL), deep-well plates, and custom trays. Maximum load capacity supports up to 32 × 50 mL tubes, 16 × 250 mL Erlenmeyer flasks, or 6 × 1 L bottles—validated per ASTM D4064 for orbital shaker load distribution and vibration transmission. The unit conforms to CE marking directives (2014/30/EU EMC, 2014/35/EU LVD), RoHS 2011/65/EU material restrictions, and GB/T 29812-2013 (Chinese national standard for laboratory shakers). While not FDA 21 CFR Part 11–certified out-of-box, audit-ready data logging (via optional RS-485 or USB interface) supports GMP traceability when implemented with validated third-party software.

Software & Data Management

The embedded microcontroller stores up to 10 user-defined protocols with recall functionality, eliminating repetitive manual entry. Real-time parameter logging is accessible via serial output (RS-232/485) or USB-to-serial adapter for integration into LabVantage, STARLIMS, or custom Python-based acquisition systems. Optional firmware upgrade enables CSV export of timestamped temperature and RPM data at 10-second intervals—supporting IQ/OQ documentation per ISO/IEC 17025 and internal SOPs for equipment qualification. All configuration changes are recorded with date/time stamps in non-volatile memory, satisfying basic ALCOA+ data integrity principles for lab notebooks and electronic records.

Applications

• Aerobic bacterial and fungal cultivation (e.g., Bacillus subtilis, Saccharomyces cerevisiae) requiring consistent DO supply
• Mammalian cell line expansion in serum-free or low-serum media where shear sensitivity demands precise orbit control
• Enzyme kinetics assays requiring simultaneous temperature stabilization and homogeneous mixing
• Antibiotic susceptibility testing (AST) using broth microdilution formats under standardized CLSI M07 guidelines
• Protein solubilization and ligand-binding equilibration in buffer screening workflows
• Environmental microbiology—water quality analysis, biodegradation studies, and activated sludge respirometry

FAQ

Does the BSD-TF270 support external temperature probes for chamber mapping?

Yes—via optional PT100 input port (firmware v2.3+), enabling validation-grade spatial temperature profiling per ISO/IEC 17025 Annex A.
Can multiple units be synchronized for parallel experiments?

No native master-slave sync; however, identical protocols can be loaded and initiated manually within ±2 seconds using the built-in timer’s “delay start” function.
Is the shaker compatible with CO₂-enriched environments?

Not designed for CO₂ operation—the chamber seal and insulation are rated for ambient air only; use only in standard atmospheric incubation applications.
What calibration documentation is provided with shipment?

Factory calibration certificate (traceable to NIM, China) covering temperature accuracy at 25 °C, 37 °C, and 55 °C, plus speed verification at 100 rpm and 200 rpm.
How often does the unit require preventive maintenance?

Annual inspection recommended: motor bearing lubrication check, door gasket integrity assessment, and PID tuning verification—no scheduled replacement parts required within first 5 years under normal use.
