Overview
The SHZ-82 Digital Air-Bath Constant-Temperature Orbital Shaker is a precision-engineered laboratory instrument designed for applications requiring simultaneous temperature control and gentle, uniform orbital agitation. Unlike water-bath shakers, the air-bath design eliminates fluid contamination risks, simplifies maintenance, and enables rapid thermal equilibration across sample vessels. Its operating principle relies on forced-air convection via a high-efficiency fan and PID-controlled heating element, ensuring stable thermal environments within ±1 °C across the chamber. The orbital motion—characterized by a 20 mm diameter circular trajectory—provides consistent mixing ideal for aerobic microbial culture, enzyme kinetics studies, solubility testing, and cell suspension maintenance. This unit is widely deployed in environmental monitoring labs (e.g., BOD₅ incubation per ASTM D5210), pharmaceutical QC facilities, academic microbiology suites, and agricultural biotechnology centers where ISO/IEC 17025-compliant sample handling and GLP-aligned operational traceability are required.
Key Features
- Orbital shaking platform with adjustable speed (0–300 rpm) and digital LED speed display for real-time monitoring and reproducible protocol execution
- PID temperature controller with ambient-to-50 °C range and ±1 °C uniformity across the chamber—validated per IEC 61000-4-3 for electromagnetic compatibility
- Aluminum alloy chamber with insulated double-wall construction and internal airflow optimization for minimal thermal gradient (<0.8 °C max deviation at setpoint)
- Non-slip silicone rubber mat and universal clamping system compatible with Erlenmeyer flasks (50–1000 mL), test tubes, and multi-well plates
- Over-temperature and motor overload protection circuits compliant with UL 61010-1 safety standards
- Front-accessible calibration port for field verification of temperature sensor (PT100 class B) and tachometer output
Sample Compatibility & Compliance
The SHZ-82 accommodates standard laboratory glassware and plastic vessels up to 1 L capacity without modification. Its open-chamber architecture allows unobstructed access for sterile technique workflows and facilitates integration into biosafety cabinets (Class II A2). The device meets essential requirements for Good Laboratory Practice (GLP) and current Good Manufacturing Practice (cGMP) environments when used with documented SOPs—including audit-ready calibration records and preventive maintenance logs. While not FDA 21 CFR Part 11–certified out-of-the-box, its analog control interface supports external data logging systems compliant with 21 CFR Part 11 Annex 11 (EU GMP) when paired with validated third-party acquisition hardware and software.
Software & Data Management
The SHZ-82 operates as a standalone analog-controlled instrument with no embedded firmware or network interface. All operational parameters—temperature setpoint, actual chamber temperature, and rotational speed—are displayed locally via dual LED readouts. For laboratories requiring electronic recordkeeping, optional analog output modules (0–5 V or 4–20 mA) are available to interface with SCADA systems, LabVIEW-based DAQ platforms, or LIMS-integrated environmental monitoring systems. Calibration certificates (traceable to NIM, China) and IQ/OQ documentation templates are provided upon request to support qualification under ISO 9001:2015 and ISO/IEC 17025:2017 frameworks.
Applications
- Biochemical oxygen demand (BOD) incubation per APHA Standard Methods 5210B and ISO 5815-1
- Maintenance of bacterial cultures (e.g., E. coli, Bacillus subtilis) during log-phase growth and cryopreservation preparation
- Enzyme assay optimization involving temperature-dependent kinetic profiling (e.g., amylase, protease activity)
- Plant tissue culture media equilibration and callus suspension propagation
- Environmental sample extraction—e.g., pesticide residue recovery from soil matrices using solvent-assisted agitation
- Quality control testing of liquid pharmaceutical formulations for homogeneity and stability under accelerated conditions
FAQ
What is the maximum load capacity of the SHZ-82 platform?
The platform supports up to 15 kg distributed evenly; typical loading includes twelve 250 mL flasks or six 1 L flasks.
Can the SHZ-82 be operated inside a cold room?
Yes—ambient operating range is 5–40 °C; performance below 15 °C may extend time-to-setpoint but does not compromise control stability.
Is the temperature sensor user-calibratable?
Yes—via front-panel calibration mode using a NIST-traceable reference thermometer (procedure detailed in Section 4.2 of the Operation Manual).
Does the unit include a timer function?
No—this model lacks built-in timing; external programmable timers or PLC integration is recommended for unattended operation.
What certifications does the SHZ-82 hold?
CE marking (2014/30/EU EMC Directive and 2014/35/EU LVD Directive), RoHS 2011/65/EU compliance, and GB/T 14710–2009 (Chinese environmental adaptability standard).
