Overview
The CZGY ZW-08A1 is a precision-engineered benchtop orbital shaker designed for consistent, low-maintenance agitation of liquid samples under ambient temperature conditions. It operates on the principle of orbital motion—where the platform rotates in a circular path with a fixed 20 mm diameter orbit—generating uniform mixing ideal for cell culture suspension, microbial growth, solubility studies, and reagent homogenization. Unlike reciprocating or vortex shakers, orbital motion minimizes shear stress on sensitive biological samples while ensuring high reproducibility across repeated runs. Its brushless DC motor delivers stable speed control across the full 40–300 rpm range without carbon brush wear or electromagnetic interference, supporting long-term operational reliability in shared laboratory environments. The unit is engineered for continuous-duty operation and complies with IEC 61010-1 safety standards for laboratory electrical equipment.
Key Features
- Brushless DC motor ensures maintenance-free performance, precise speed regulation, and extended service life (>20,000 hours MTBF)
- LCD digital display with intuitive keypad interface for real-time monitoring and adjustment of speed and timer settings
- Wide-speed range (40–300 rpm) with ±1 rpm speed stability at setpoint, calibrated traceable to internal reference
- 20 mm orbital diameter optimized for efficient oxygen transfer and suspension uniformity in Erlenmeyer flasks and test tubes
- Programmable timer spanning 0–9999 minutes (or hours), supporting both single-run and auto-restart modes
- Single-tier aluminum alloy platform (300 × 300 mm usable area) with integrated 16-position 150 mL flask clamping system
- Low-noise design (<50 dB(A) at 1 m distance) suitable for open-lab layouts and laminar flow hoods
- Compact footprint (400 × 350 × 220 mm) and lightweight construction (≈12 kg) facilitate placement on standard lab benches or mobile carts
Sample Compatibility & Compliance
The ZW-08A1 accommodates standard microbiological and biochemical vessels including glass and PET Erlenmeyer flasks (50–500 mL), centrifuge tubes (15–50 mL), and multi-well plates (with optional adapter). Its fixed 20 mm orbit and smooth acceleration profile prevent splashing and foaming during prolonged incubation of low-viscosity media (e.g., LB broth, PBS, yeast extract–peptone–dextrose medium). The unit meets CE marking requirements under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and conforms to ISO/IEC 17025-aligned calibration practices for speed and timer verification. While not thermostatically regulated, its ambient-only operation aligns with ASTM D4084-22 guidelines for non-temperature-controlled agitation protocols in environmental and pharmaceutical QC labs.
Software & Data Management
The ZW-08A1 operates as a standalone instrument with no embedded firmware-based data logging or network connectivity. All operational parameters—including set speed, elapsed time, and remaining timer duration—are displayed locally on the LCD screen. For GLP/GMP-compliant environments, users may integrate the shaker into validated workflows using external electronic lab notebooks (ELNs) or LIMS platforms via manual entry or barcode-scanned protocol assignment. Though it lacks FDA 21 CFR Part 11-compliant audit trails, its mechanical simplicity and deterministic timer logic support retrospective validation per ISO 13485 Annex C and USP Analytical Instrument Qualification (AIQ) categories A–B.
Applications
- Microbial cultivation (E. coli, Bacillus spp., Pseudomonas) in aerobic shake-flask bioreactors
- Cell line maintenance in suspension culture (CHO, HEK293, Sf9) prior to transfection or harvest
- Enzyme kinetics assays requiring uniform substrate mixing without denaturation
- Environmental water sample homogenization prior to filtration or nutrient analysis (APHA 2540D)
- Extraction efficiency optimization for plant metabolites or soil-bound contaminants (EPA Method 3550C)
- Quality control testing of buffer consistency, reagent solubility, and polymer dissolution profiles
FAQ
Is the ZW-08A1 compatible with incubators or cold rooms?
No—the unit is rated for ambient operation only (10–35°C, ≤80% RH non-condensing) and lacks thermal insulation or condensation protection.
Can the timer be set in hours instead of minutes?
Yes—timer input accepts values up to 9999; users may interpret units as minutes or hours based on protocol requirements.
Does the shaker include over-speed or over-temperature protection?
It features motor over-current protection and thermal cut-off at ≥85°C motor winding temperature, but no platform temperature sensing.
What certifications does the ZW-08A1 hold for international export?
CE-marked per EU directives; RoHS 2011/65/EU compliant; factory calibration certificate provided upon request.
Is third-party calibration available?
Yes—accredited metrology laboratories can perform speed and timer verification per ISO/IEC 17025, using NIST-traceable tachometers and stopwatch standards.
