Overview
The OHAUS SHWV02AL 3D Orbital Shaker is an engineered platform for precise, low-shear orbital motion under controlled temperature conditions. Utilizing a balanced eccentric drive mechanism and a dynamically stabilized tilt-axis system, it delivers consistent 3D orbital oscillation—combining horizontal rotation with programmable angular inclination—to enhance mixing uniformity in viscous or density-stratified samples. Designed specifically for life science laboratories requiring reproducible agitation in demanding thermal environments, the SHWV02AL supports applications where conventional linear or circular shakers risk sample stratification, sedimentation, or surface shearing. Its integrated refrigeration and heating system enables operation across a wide ambient-compensated range (−20°C to +65°C), making it suitable for cold-chain cell culture conditioning, hybridization protocols requiring thermal ramping, and low-temperature enzymatic assays.
Key Features
- Low-Profile Ergonomic Design: 120 mm clearance height allows seamless integration into standard CO2 incubators, biosafety cabinets, and walk-in cold rooms without compromising airflow or spatial access.
- Cast-Aluminum Structural Base: Provides mechanical rigidity and vibration damping, minimizing harmonic resonance during extended low-speed operation (1–15 rpm) critical for fragile suspension cultures.
- Independent Analog Control System: Dedicated rotary dials for speed (1–75 rpm), tilt angle (0–20°), and timer (1–120 min) enable intuitive, glove-compatible operation without software dependency or touchscreen calibration drift.
- Gradual Acceleration Ramp: Motor control firmware implements soft-start profiles to prevent splashing in open vessels or disruption of adherent monolayers during initiation of motion.
- Integrated Overload & Obstruction Detection: Real-time current monitoring triggers audible alarm and LED indicator upon mechanical resistance exceeding safe torque thresholds—protecting both motor integrity and sample containment.
- Condensate-Resistant Enclosure: Sealed electronics housing and angled drip channels direct condensate away from PCBs and drive components, ensuring reliable function at 80% non-condensing relative humidity across the full operating temperature span.
Sample Compatibility & Compliance
The SHWV02AL accommodates standard labware including multi-well plates (6–96-well), Erlenmeyer flasks (up to 2 L), Petri dishes, and gel trays via optional universal clamping kits. Its motion profile meets ISO 20737:2021 requirements for orbital shaker performance verification and supports GLP-compliant workflows when paired with external data loggers. While not inherently 21 CFR Part 11 compliant due to its analog interface, audit trails can be maintained through external timestamped video recording or connected environmental monitors—common practice in academic and contract research settings performing ASTM D4097 (gel staining agitation) or USP endotoxin assay preparation.
Software & Data Management
This instrument operates as a standalone hardware platform with no embedded firmware, network interface, or proprietary software dependency. All operational parameters are set locally via tactile controls, eliminating cybersecurity vulnerabilities associated with IoT-enabled devices. For laboratories requiring electronic records, third-party USB data loggers (e.g., Omega OM-DAQPRO-5300) may be mounted externally to capture real-time temperature and rotational speed outputs via analog voltage signals. Calibration certificates traceable to NIST standards are provided with each unit, and annual verification follows OHAUS-recommended procedures outlined in Technical Bulletin TB-SH-002.
Applications
- Gel electrophoresis staining and destaining (Coomassie, silver, SYBR Safe)
- Nucleic acid hybridization (Southern/Northern blotting, FISH probe incubation)
- Cell suspension culture maintenance under hypothermic or normothermic conditions
- Antibody-antigen binding kinetics in ELISA plate-based assays
- Tissue decalcification and permeabilization in histopathology workflows
- Low-shear dissolution testing of biopolymer hydrogels and scaffold matrices
FAQ
Does the SHWV02AL support programmable multi-step temperature ramps?
No—temperature is manually set via analog dial and held at a single setpoint; ramping requires external controllers.
Can this shaker operate continuously beyond 120 minutes?
Yes—the timer is optional; disabling it enables indefinite operation with manual stop.
Is the tilt angle calibrated at factory level, and is recalibration possible onsite?
Tilt angle is factory-verified using optical inclinometry; field recalibration is not supported, but routine verification with digital inclinometer is recommended per ISO/IEC 17025 internal audit schedules.
What is the maximum load capacity at 75 rpm and 20° tilt?
Rated for 5 kg evenly distributed load; derating to 3.5 kg advised above 50 rpm with >15° tilt to maintain mechanical longevity.
Are replacement parts such as drive belts or tilt actuators available through OHAUS distribution channels?
Yes—OHAUS part numbers SHWV-DRV-BELT and SHWV-TILT-ACTUATOR are stocked globally with typical lead time of 5–7 business days.
