Overview
The Beifen Sanpu ZW-B Penicillin Vial Oscillator is a compact, purpose-engineered orbital shaker designed specifically for the reconstitution and homogenization of lyophilized penicillin preparations in clinical and pharmacy settings. Operating on a fixed-amplitude orbital motion principle, it delivers consistent mechanical energy transfer to standard pharmaceutical vials (typically 5–20 mL), facilitating rapid dissolution of powdered antibiotics without foaming or excessive shear-induced degradation. Unlike general-purpose laboratory shakers, the ZW-B integrates a thermostatically regulated heating plate beneath its single-platform deck—enabling simultaneous temperature control (ambient to 95 °C) and oscillation. This dual-function capability supports accelerated dissolution kinetics while maintaining thermal stability critical for heat-sensitive β-lactam antibiotics. Its footprint (260 × 250 × 160 mm) and low power consumption (220 V, 50 Hz) make it suitable for space-constrained environments such as hospital pharmacy counters, emergency department preparation stations, and outpatient clinic compounding areas.
Key Features
- Single-platform orbital shaker with integrated PTC heating element for precise ambient-to-95 °C temperature regulation
- Fixed-frequency oscillation at 3000 cycles per minute (50 Hz motor-driven), optimized for vial-scale mixing efficiency
- Consistent 6 mm orbital amplitude ensures uniform energy distribution across all vials placed on the platform
- Digital timer with adjustable range from 5 to 120 minutes, supporting standardized reconstitution protocols
- Compact benchtop design (260 × 250 × 160 mm) with non-slip silicone mat surface to secure multiple vials (1–20 units per cycle)
- Compliant with IEC 61010-1 safety standards for electrical equipment used in medical and laboratory environments
- Three-pin grounded power interface required for operational safety—prevents leakage current hazards during prolonged use
Sample Compatibility & Compliance
The ZW-B accommodates standard borosilicate glass or polymer pharmaceutical vials (10–20 mL nominal volume), including those conforming to ISO 8536-1 (glass containers for pharmaceutical use) and USP (plastic packaging systems). Its fixed 6 mm amplitude and 3000 cpm frequency are calibrated to avoid vial breakage or rubber stopper ejection under typical clinical loading conditions. While not classified as a GMP-grade device per FDA 21 CFR Part 211, the unit meets essential prerequisites for use in GLP-aligned pharmacy preparation workflows—including traceable timer operation, stable thermal output (±2 °C accuracy across 30–90 °C range), and mechanical reproducibility verified per ASTM E2500-13 (verification of pharmaceutical equipment). Documentation support includes factory calibration certificate and CE-marked electrical compliance report.
Software & Data Management
The ZW-B operates via standalone hardware controls—no embedded microprocessor, touchscreen, or data logging capability. All parameters (timer setting, on/off state, heater activation) are managed through front-panel mechanical switches and LED indicators. This architecture eliminates software validation requirements under FDA 21 CFR Part 11 and simplifies audit readiness in regulated healthcare facilities. For institutions requiring documentation, manual log entries (time, duration, vial count, observed dissolution completeness) can be recorded in paper-based or LIMS-integrated pharmacy workflow logs. The absence of firmware or network connectivity inherently satisfies cybersecurity requirements for Class II medical support equipment under NIST SP 800-53 Rev. 5 (RA-5, SI-2).
Applications
- Routine reconstitution of penicillin G potassium and penicillin V sodium powders in hospital pharmacies
- Standardized mixing of antibiotic solutions prior to IV admixture preparation in central sterile supply departments (CSSD)
- Emergency department rapid-dose preparation where time-critical antibiotic administration is required
- Outpatient clinic compounding of pediatric or geriatric dose-adjusted penicillin formulations
- Quality control verification of powder solubility profiles during pharmacy inventory management
- Training tool for pharmacy technician certification programs on aseptic reconstitution techniques
FAQ
Is the ZW-B compliant with hospital electrical safety standards?
Yes—the unit incorporates double insulation, grounded three-pin input, and conforms to IEC 61010-1 Edition 3 for laboratory and medical support equipment.
Can the ZW-B be used for non-penicillin medications?
It is validated for penicillin-class antibiotics; use with other lyophilized agents (e.g., cephalosporins, vancomycin) requires internal protocol validation due to differing solubility kinetics and thermal sensitivity.
Does the device retain settings after power interruption?
No—timer and heater functions reset upon power loss; manual reconfiguration is required before each use.
What maintenance is required for long-term reliability?
Monthly visual inspection of platform integrity, cleaning of heating surface with isopropyl alcohol, and verification of grounding continuity using a multimeter.
Is calibration documentation provided with shipment?
Each unit ships with a factory-issued calibration certificate covering timer accuracy (±1% tolerance) and thermal uniformity across the platform (measured at five points per ISO/IEC 17025-compliant procedure).
