YIHENG DV-2006L LCD Display Constant Temperature Orbital Shaker

Overview

The YIHENG DV-2006L is a microprocessor-controlled air-jacketed orbital shaker engineered for precision incubation and agitation of biological samples in life science laboratories. It integrates temperature regulation and orbital motion within a single compact chamber—eliminating the need to transfer cultures between separate incubators and shakers. The device operates on the principle of controlled convection heating and sinusoidal orbital motion (20 mm diameter), delivering uniform thermal distribution and consistent mixing across all vessel positions. Designed for long-term unattended operation under GLP-compliant workflows, the DV-2006L supports applications ranging from microbial growth kinetics and cell suspension culture to enzyme reaction optimization and biochemical assay development. Its thermally insulated double-wall construction, low-heat-output DC motor, and fluorine-free refrigerant system meet international environmental and safety standards including ISO 14001 and IEC 61000-6-3.

Key Features

• Integrated incubation-shaking functionality: Eliminates workflow interruption by enabling seamless transition from shaking mode to static incubation mode post-experiment.
• Large backlit LCD display with intuitive menu-driven interface—supports real-time monitoring of setpoints and actual values for temperature, speed, and remaining time.
• High-efficiency DC motor with high starting torque and wide-speed range (40–300 rpm), ensuring stable acceleration, minimal vibration transmission, and maintenance-free continuous operation (>72 h).
• Double-glazed, tempered observation window with low-emissivity coating provides optical clarity during operation while minimizing heat loss and external ambient interference.
• Interior chamber, platform surface, and adjustable shelves constructed entirely from electropolished 304 stainless steel—resistant to corrosion, compatible with common laboratory disinfectants, and compliant with USP analytical instrument qualification requirements.
• 25 mm diameter access port on left side wall enables flexible integration with external sensors, gas lines, or pH/DO probes without compromising chamber integrity.
• Intelligent fault diagnostics: Real-time error codes displayed on LCD screen (e.g., E01 = overtemperature, E03 = motor stall, E05 = sensor open-circuit) facilitate rapid troubleshooting and minimize downtime.

Sample Compatibility & Compliance

The DV-2006L accommodates standard culture vessels—including Erlenmeyer flasks (50–2000 mL), test tubes, deep-well plates, and custom bioreactor sleeves—via interchangeable platforms and universal clamps (sold separately). Its uniform temperature distribution (±0.3°C at 37°C, measured per ASTM E2234) and consistent orbital motion profile ensure reproducible growth conditions across all load configurations. The unit conforms to electromagnetic compatibility (EMC) Class B limits (EN 61326-1), electrical safety standards (IEC 61010-1), and is certified for use in ISO Class 5–8 cleanroom-adjacent environments. Optional UV-C germicidal lamp (254 nm, 15 W) installed on rear chamber wall meets ISO 14644-1 particle control recommendations for reducing airborne bioburden during non-operational periods.

Software & Data Management

Equipped with RS-485 serial interface and USB host port (U-disk logging), the DV-2006L supports bidirectional communication with PC-based control software (YIHENG LabControl Suite v3.2). Users can configure multi-segment programs (up to 9 segments per cycle), log timestamped temperature/speed/time data at user-defined intervals (1 s–60 min), and export CSV-formatted reports compatible with LIMS systems. Audit trail functionality records operator ID, parameter changes, alarm events, and system power cycles—fully compliant with FDA 21 CFR Part 11 requirements when deployed with electronic signature modules. Optional thermal printer interface enables direct hardcopy output of validation protocols and run summaries.

Applications

• Mammalian and insect cell suspension culture under controlled O₂/CO₂-balanced atmospheres (when used with gas-tight enclosures)
• Bacterial and yeast fermentation studies requiring precise temperature–agitation coupling
• Protein expression optimization in shake-flask bioreactors
• Enzyme kinetic assays where substrate homogeneity and thermal stability are critical
• Antibiotic susceptibility testing using broth microdilution formats
• Environmental microbiology sample enrichment under regulated thermal stress conditions

FAQ

What is the temperature uniformity specification across the platform at 37°C?
Typical uniformity is ±0.3°C (measured at nine points per ICH Q5C Annex 1), verified during factory calibration and documented in the Certificate of Conformance.
Can the DV-2006L operate continuously for 7 days without intervention?
Yes—its brushless DC motor, passive cooling architecture, and redundant thermal cutoffs enable validated 168-hour uninterrupted operation under nominal load conditions.
Is the USB data logging function compatible with Windows 11 and macOS Ventura?
Yes—YIHENG LabControl Suite supports Windows 10/11 (64-bit) and macOS 12–14 via native drivers; no virtual machine or emulation layer required.
Does the unit support external CO₂ or humidity control integration?
Not natively—but the 25 mm access port and programmable analog output (0–5 V) allow third-party integration with gas controllers or humidification modules using OEM-approved signal conditioning hardware.
How often does the UV-C lamp require replacement to maintain >90% germicidal efficacy?
Per manufacturer specifications, the UV-C lamp maintains ≥90% irradiance output for 5,000 hours of cumulative use; annual recalibration with a NIST-traceable radiometer is recommended.
