Langbo YY-82A Oil-Bath Orbital Shaker

Overview

The Langbo YY-82A Oil-Bath Orbital Shaker integrates precise thermal regulation with controlled orbital agitation in a single compact platform. Unlike air-jacketed incubator shakers, this instrument employs a thermally stable oil bath as the primary heat-transfer medium—enabling uniform temperature distribution across the entire sample zone and minimizing thermal gradients during extended operation. The system operates on the principle of conductive heating via high-flash-point silicone-based thermal oil, regulated by a digital PID controller with real-time feedback from a calibrated PT100 sensor embedded in the bath reservoir. Its operational envelope spans from ambient +5°C up to 300°C, making it suitable for applications requiring elevated-temperature kinetic studies, solvent-based extractions, enzymatic reactions under non-aqueous conditions, and accelerated stability testing protocols. Engineered for reproducibility in routine and research-grade laboratories, the YY-82A delivers consistent orbital motion (20 mm diameter) at speeds adjustable from standstill to 280 rpm—ensuring compatibility with standard flasks, tubes, and custom vessels mounted on its single stainless-steel platform.

Key Features

• Dual-function design: Simultaneous temperature control and orbital shaking in one unit—eliminating need for separate incubators or shakers.
• Thermal oil bath architecture: Provides superior thermal homogeneity vs. air-heated systems; reduces overshoot and improves long-term setpoint stability.
• Digital PID temperature controller with LED display: Enables intuitive setpoint entry, real-time temperature readout, and programmable ramp-hold profiles (via optional firmware upgrade).
• Stainless steel inner chamber and powder-coated exterior: Resists corrosion from organic solvents, acids, and high-temperature oil vapors; supports frequent decontamination.
• Adjustable timer (1–120 minutes): Auto-shutdown function prevents overheating or over-agitation during unattended runs.
• Robust mechanical drive: Brushless DC motor ensures low-vibration performance and extended service life under continuous duty cycles.
• Integrated safety mechanisms: Over-temperature cutoff, dry-run protection, and motor thermal overload sensing comply with IEC 61010-1 Class II requirements.

Sample Compatibility & Compliance

The YY-82A accommodates standard laboratory glassware—including Erlenmeyer flasks (50–2000 mL), test tubes, centrifuge tubes, and custom reaction vessels—secured via universal clamps or silicone matting. Its open-bath configuration allows direct immersion of containers into the thermal oil, ensuring rapid thermal equilibration. The unit is designed for use in environments adhering to Good Laboratory Practice (GLP) frameworks; audit-ready operation is supported through manual logbook entries aligned with ISO/IEC 17025 clause 7.7 (equipment records) and FDA 21 CFR Part 11 principles (when paired with validated external data capture systems). While not certified for IVD or GMP manufacturing, it meets essential electrical safety (EN 61010-1) and electromagnetic compatibility (EN 61326-1) standards applicable to general-purpose lab equipment.

Software & Data Management

The YY-82A operates as a standalone instrument with no embedded software or network interface. All parameter inputs and status monitoring occur via front-panel controls and LED display. For traceable data recording, users are advised to integrate external logging solutions—such as USB-connected thermocouple dataloggers or LabVIEW-compatible DAQ systems—configured to sample temperature and rotational speed at user-defined intervals. Calibration certificates (NIST-traceable PT100 sensor, rpm tachometer) are provided upon request and should be renewed annually per internal quality SOPs. Firmware updates are not available; hardware-level calibration adjustments require authorized service technician intervention.

Applications

• Kinetic studies of thermally activated biochemical reactions (e.g., lipase-catalyzed transesterification in organic media).
• Accelerated solvent extraction of plant metabolites, polymers, or environmental contaminants using heated oil-phase systems.
• High-temperature cell lysis protocols where aqueous buffers are replaced by biocompatible oils.
• Calibration validation of thermal sensors and rheological probes under dynamic heating/agitation conditions.
• Preparative-scale synthesis requiring simultaneous heating and mixing—particularly where microwave or reflux methods pose safety or scalability limitations.
• Teaching laboratories conducting comparative experiments on heat transfer efficiency between air and liquid-phase thermal coupling.

FAQ

Is the YY-82A suitable for use with flammable solvents?

No. The oil bath operates up to 300°C and uses high-boiling-point silicone oil; however, it is not explosion-proof. Flammable solvents must be excluded from the bath environment per NFPA 45 guidelines.
Can the oscillation speed be maintained accurately at maximum temperature?

Yes. The brushless DC motor and isolated drive train maintain rated speed stability (±3 rpm) across the full temperature range, verified per ASTM E2500-13 Annex A3.
What maintenance is required for long-term reliability?

Annual inspection of oil level and clarity; replacement every 24 months or after 500 operational hours; cleaning of stainless chamber with non-chlorinated solvents only.
Does the unit support external temperature probe input for secondary verification?

Not natively. External probe integration requires third-party signal conditioning hardware compatible with 0–5 V analog output interfaces.
Is CE marking applied to this model?

The YY-82A complies with relevant EU directives (EMC, LVD) but is supplied without CE marking for export markets; end-user responsibility includes local conformity assessment per national regulations.
