Boxun BSD-TF370 Benchtop Incubated Orbital Shaker

Overview

The Boxun BSD-TF370 Benchtop Incubated Orbital Shaker is an engineered solution for controlled, temperature-regulated agitation in microbiology, cell culture, molecular biology, and bioprocess development laboratories. It operates on the principle of orbital shaking—generating a circular motion with a fixed 40 mm orbit diameter—to ensure uniform suspension, enhanced oxygen transfer, and consistent mixing across liquid cultures. Unlike reciprocating or vortex shakers, orbital motion minimizes shear stress on sensitive biological samples while maximizing surface-to-volume gas exchange—a critical factor in aerobic microbial growth and recombinant protein expression. Integrated P.I.D. temperature control, coupled with real-time environmental scanning via a dedicated microprocessor, enables precise thermal regulation from ambient +6°C up to 60°C. The unit’s sealed 70 L chamber, combined with its single large-format platform (440 × 420 mm), supports scalable vessel configurations—from high-density microtiter plates to liter-scale flasks—without compromising thermal homogeneity or mechanical stability.

Key Features

• Single-axis direct-drive mechanism with brushless DC motor: delivers constant torque across the full 25–240 rpm range, eliminates carbon brush wear, and ensures immunity to line voltage fluctuations (±10% tolerance).
• Microprocessor-controlled soft-start acceleration profile: prevents sample splashing or vessel displacement during startup by gradually ramping speed over a user-defined interval.
• Backlit LCD interface with dual-parameter display: simultaneously shows setpoints and real-time values for temperature, speed, and remaining timer duration; all parameters are password-locked to prevent accidental modification.
• Comprehensive safety architecture: includes overtemperature cut-off with independent thermal fuse, audible/visual alarm for temperature deviation >±2°C, and automatic power resumption after grid interruption (with memory retention of active protocol).
• Orbit amplitude fixed at 40 mm—optimized for Erlenmeyer flask aeration and suspension culture consistency—while frequency remains continuously adjustable without mechanical recalibration.
• Structural design compliant with IEC 61010-1 for laboratory equipment safety; chassis constructed from powder-coated steel with reinforced platform support to dampen resonance at high-frequency operation.

Sample Compatibility & Compliance

The BSD-TF370 accommodates standard laboratory vessels including glass and polycarbonate Erlenmeyer flasks (50–1000 mL), deep-well microplates, and custom bioreactor bags mounted on rigid carriers. Its platform load capacity supports up to 6 × 1000 mL flasks or 32 × 50 mL tubes under balanced loading conditions. Temperature uniformity (±1.0°C at 37°C) meets ISO 13408-2 requirements for incubator performance validation in aseptic processing environments. While not certified for GMP manufacturing, the instrument supports GLP-compliant workflows through traceable parameter logging, user-accessible calibration offsets, and audit-ready operational history (when paired with optional data export module). All electrical components conform to CE marking directives and RoHS 2011/65/EU material restrictions.

Software & Data Management

The embedded controller stores up to 10 programmable protocols with independent timer, temperature, and speed settings. Each protocol retains start time, elapsed duration, and final status (normal completion vs. alarm-triggered halt). USB port enables firmware updates and raw parameter export in CSV format for integration into LIMS or ELN systems. Optional Boxun DataLink software (v3.2+) provides remote monitoring via Ethernet connection, configurable alarm notifications (email/SNMP), and 21 CFR Part 11–compliant electronic signature support for validated environments. Audit trails record all parameter changes—including operator ID, timestamp, and pre-/post-modification values—with immutable storage on internal flash memory.

Applications

• Microbial cultivation (E. coli, yeast, Bacillus spp.) under defined dissolved oxygen regimes.
• Mammalian and insect cell suspension expansion in serum-free or low-serum media.
• Enzyme kinetics assays requiring stable temperature and homogeneous mixing.
• Antibiotic susceptibility testing using broth microdilution formats.
• Preparative-scale protein expression in shake-flask bioreactors prior to bioreactor scale-up.
• Environmental microbiology studies involving soil slurry or wastewater enrichment cultures.

FAQ

Does the BSD-TF370 support external temperature probes for chamber mapping?
Yes—via optional PT100 input port (model BSD-TF370-EXT-TP), enabling real-time validation of spatial temperature distribution per ISO 14644-3.
Can the shaker operate continuously beyond 999 hours?
No—the timer maxes at 999 h; however, users may configure repeat cycles or disable timing for uninterrupted operation.
Is the platform compatible with magnetic stir bars or heating modules?
No—the platform is mechanically isolated for orbital motion only; integration of auxiliary heating/stirring requires third-party adapters not validated by Boxun.
What maintenance is required for the brushless DC motor?
None—no lubrication, commutator cleaning, or brush replacement is necessary throughout the rated service life (≥20,000 operating hours).
How is temperature uniformity verified during factory calibration?
Using nine calibrated NIST-traceable PT100 sensors placed per ISO 29183:2021 Annex B, with results documented in the Certificate of Conformance shipped with each unit.
