Overview
The Langbo ZHWY-2112B Dual-Layer High-Capacity Incubated Orbital Shaker is an engineered platform for scalable, temperature-controlled suspension culture and mixing applications in microbiology, molecular biology, fermentation, and bioprocess development laboratories. Designed around a robust vertical dual-shelf architecture, it delivers high-volume throughput without compromising spatial efficiency—ideal for core facilities and QC labs requiring parallel processing of multiple culture vessels under tightly regulated thermal and mechanical conditions. Its orbital motion (25 mm diameter) ensures gentle yet effective homogenization of liquid cultures, minimizing shear stress on sensitive microbial or mammalian cells while maintaining uniform oxygen transfer and nutrient dispersion. The system operates on a PID-controlled forced-air convection heating system, enabling precise thermal regulation across the full working range (ambient +5°C to 60°C), with stability ≤±0.5°C at 37°C and uniformity ≤±1°C at 25°C—performance metrics aligned with ISO 17025-compliant environmental control requirements for biological incubation.
Key Features
- Dual-layer stainless steel shelves (970 × 560 mm each), supporting up to 582 L total chamber volume and accommodating up to 164 × 100 mL flasks or 36 × 1000 mL bottles per run
- PID microprocessor-based environmental controller with real-time LCD display (backlit, graphical interface) showing setpoints and actual values for temperature, speed, and time
- Intelligent acceleration ramping circuitry ensures smooth start-up and deceleration, protecting culture integrity during initiation and cessation of oscillation
- Comprehensive safety architecture: over-temperature audiovisual alarm, motor overheat detection, independent power cutoff on thermal runaway, and automatic recovery after external power interruption
- Parameter lock function prevents accidental modification of operational settings; memory retention preserves user-defined protocols across power cycles
- Brushless AC induction motor—maintenance-free, low-noise, high-torque output across full 30–300 rpm range with ±1 rpm speed accuracy
- Ergonomic double-door access with tempered glass viewing window and electrostatically sprayed steel enclosure for corrosion resistance and cleanroom-compatible operation
Sample Compatibility & Compliance
The ZHWY-2112B accommodates standard laboratory vessels—including Erlenmeyer flasks (100–1000 mL), culture bottles, deep-well plates, and custom bioreactor sleeves—across both shelves simultaneously. Its chamber geometry and airflow design support consistent thermal distribution even under maximum load conditions, validated per ASTM E1510-22 guidelines for incubator performance verification. The unit meets CE marking requirements for electrical safety (EN 61010-1) and electromagnetic compatibility (EN 61326-1). While not certified for GMP manufacturing environments, its parameter logging, password-protected configuration, and audit-ready timer functionality align with GLP documentation expectations for non-clinical laboratory studies (OECD 1998, FDA Guidance for Industry on GLPs).
Software & Data Management
The onboard controller supports manual operation and time-programmed sequencing up to 500 hours, with endpoint audiovisual alerts and automatic shutdown. Though no external PC interface is included, all operational parameters—including elapsed time, current temperature, and rotational speed—are continuously logged in non-volatile memory and displayed in real time. For laboratories requiring electronic records, optional RS-485 or USB-to-serial adapters (sold separately) enable integration with third-party data acquisition platforms compliant with 21 CFR Part 11 when paired with validated software solutions. All firmware revisions are traceable via version stamping in the display menu, supporting internal calibration and maintenance recordkeeping.
Applications
- High-yield microbial cultivation (E. coli, yeast, Bacillus spp.) under controlled aeration and temperature
- Protein expression optimization using autoinduction media in shake-flask bioreactors
- Cell line expansion and transfection preparation in suspension-adapted mammalian systems
- Enzyme activity assays requiring precise thermal stabilization during kinetic measurement
- Environmental microbiology studies involving soil slurry enrichment or waterborne pathogen propagation
- Preparative-scale biochemical extractions where consistent agitation enhances solute diffusion
FAQ
What is the minimum ambient temperature required for stable operation?
The unit is rated for use in environments between 5°C and 25°C ambient temperature to ensure accurate thermal control within the chamber.
Can the shaker maintain 37°C while operating at 250 rpm?
Yes—the forced-air convection system and PID algorithm are designed for simultaneous precision in temperature and speed control across the full operational envelope.
Is the inner chamber constructed from stainless steel?
The shelves and structural frame are stainless steel; the interior lining is electropolished 304 stainless steel for enhanced corrosion resistance and ease of decontamination.
Does the device support external data export or remote monitoring?
No native Ethernet or Wi-Fi connectivity is provided; however, analog/digital I/O expansion modules and serial communication adapters are available as field-installable options.
What safety certifications does this model carry?
It complies with EN 61010-1 (safety of laboratory equipment) and EN 61326-1 (EMC for laboratory use), with CE marking affixed to the rear panel.
