Overview
The DRETOP ZYC-100B Air-Bath Constant-Temperature Orbital Shaker is an integrated laboratory instrument engineered for precise temperature-controlled orbital agitation of biological and biochemical samples. It operates on the principle of air-bath convection heating—where heated ambient air circulates uniformly around the sample platform—to achieve rapid thermal equilibration and high spatial temperature uniformity across the stainless-steel shaking surface. Unlike water-bath shakers, this design eliminates contamination risks from water ingress, condensation, or microbial growth in bath fluid, making it especially suitable for long-duration microbial culture, enzyme kinetics, solubility studies, and cell suspension maintenance under sterile or semi-sterile conditions. Its orbital motion (26 mm diameter) ensures gentle yet effective mixing of flasks, tubes, and culture vessels without vortexing or foaming—critical for aerobic microbial growth, protein expression, and hybridization protocols requiring consistent gas exchange.
Key Features
- Microprocessor-based PID temperature and speed control with ±0.1°C temperature accuracy and ±1 rpm speed regulation, ensuring high reproducibility across repeated experiments.
- Backlit LCD display with intuitive angled control panel showing real-time temperature, rotational speed, elapsed time, and system status—including audible/visual alarms for over-temperature, over-speed, or timer completion events.
- Brushless DC motor drive delivering maintenance-free operation, constant torque across the full 0–300 rpm range, and extended service life (>20,000 hours).
- Three-dimensional eccentric cam drive mechanism with soft-start functionality to minimize mechanical shock during acceleration—reducing splashing, cross-contamination risk, and sample loss.
- Electrostatically coated steel housing with 304 stainless-steel inner chamber and platform; seamless welds and rounded corners facilitate cleaning and compliance with GLP hygiene requirements.
- Parameter lockout and auto-recovery function: settings persist through power interruption and restore automatically upon re-energization, supporting unattended overnight operation.
- Integrated safety suite including over-temperature cutoff, overspeed shutdown, timer-based automatic stop, and programmable temperature/speed correction offsets.
Sample Compatibility & Compliance
The ZYC-100B accommodates standard laboratory glassware and plastic vessels via interchangeable clamping options—including universal spring clips, fixed Erlenmeyer flask holders (100 mL × 9, 250 mL × 3, or 500 mL × 2 configurations), and custom-fit tube racks. Its 290 × 260 mm platform supports loads up to 15 kg with balanced mass distribution. The unit meets IEC 61010-1:2010 safety standards for laboratory electrical equipment and conforms to electromagnetic compatibility (EMC) requirements per EN 61326-1. While not certified for GMP production environments, its design supports audit-ready documentation when used within ISO/IEC 17025-accredited testing laboratories. Optional UV germicidal lamps (254 nm) enable periodic decontamination of internal surfaces, aligning with biosafety Level 1 (BSL-1) containment practices.
Software & Data Management
The ZYC-100B supports optional USB data logging via a dedicated interface module, enabling timestamped export of temperature, speed, and runtime data in CSV format. This facilitates traceability for method validation, regulatory submissions (e.g., FDA 21 CFR Part 11-compliant workflows when paired with validated third-party software), and quality assurance records. No proprietary software is required—raw logs are readable in Excel or LabChart. Firmware updates are performed locally via USB stick, eliminating network dependencies and enhancing cybersecurity posture in regulated lab networks.
Applications
This shaker serves critical roles in academic research, pharmaceutical QC, and bioprocess development labs. Typical applications include: bacterial and yeast culture expansion (E. coli, S. cerevisiae) under aerobic conditions; plasmid amplification and protein expression in LB or TB media; enzymatic assay incubation (e.g., kinase or phosphatase activity at controlled temperatures); dissolution testing of solid dosage forms; antigen-antibody binding kinetics; and environmental microbiology (e.g., BOD bottle agitation per ASTM D5210). Its RT+5°C to 60°C operating envelope covers mesophilic growth ranges and enables accelerated stability studies compliant with ICH Q1A(R3).
FAQ
What is the maximum load capacity for the ZYC-100B platform?
The unit supports up to 15 kg distributed evenly across the 290 × 260 mm stainless-steel platform.
Does the ZYC-100B support external temperature probes or PT100 calibration inputs?
No—it relies on factory-calibrated internal NTC sensors; however, user-defined temperature offset correction is available in the setup menu.
Can this shaker be used inside a CO₂ incubator or laminar flow hood?
It is not rated for humidified or high-CO₂ atmospheres; operation must occur in ambient laboratory air with adequate ventilation.
Is the oscillation motion truly orbital, or is it reciprocating?
The drive mechanism produces true circular orbital motion (26 mm diameter), confirmed by ISO 8573-1-compliant motion profiling during factory acceptance testing.
What certifications does the ZYC-100B hold for international shipment?
It carries CE marking (EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU) and complies with RoHS 2011/65/EU restrictions on hazardous substances.
