DRETOP ZYC-302L Vertical Dual-Door Air-Bath Orbital Shaker

Overview

The DRETOP ZYC-302L Vertical Dual-Door Air-Bath Orbital Shaker is an integrated laboratory instrument engineered for simultaneous precise temperature control and uniform orbital agitation. It operates on the principle of forced-air convection heating combined with balanced eccentric-drive orbital motion—ensuring homogeneous thermal distribution across dual independently accessible chambers and consistent shear-free mixing of liquid cultures. Designed for rigorous life science workflows, this shaker supports applications requiring strict environmental reproducibility, including microbial growth kinetics, enzyme activity assays, cell suspension culture, and small-scale bioprocess development. Its vertical dual-door architecture optimizes footprint efficiency while enabling independent access to upper and lower shelves—minimizing thermal disturbance during sample handling and supporting parallel experiments under identical or differentiated setpoints.

Key Features

• Microprocessor-based P.I.D. temperature and speed controller with real-time digital display (backlit LCD) showing setpoint/actual values for temperature (±0.1°C resolution), rotational speed (±1 rpm accuracy), and elapsed time.
• Dual independent stainless-steel oscillating platforms (710 × 455 mm each), each equipped with a 26 mm orbital diameter drive mechanism powered by maintenance-free brushless DC motors—delivering stable torque output across the full 0–300 rpm range.
• Tempered glass double-door viewing window with integrated LED lighting; doors open outward with gas-spring-assisted hinges for ergonomic access and reduced heat loss.
• Three-dimensional offset triple-cam drive system with soft-start ramp-up logic to prevent splashing of low-viscosity samples during acceleration/deceleration cycles.
• Comprehensive safety suite: over-temperature alarm (with audible/visual alert), overspeed protection, timed shutdown, auto-restart after power interruption, and parameter encryption to prevent unauthorized configuration changes.
• Electrostatically coated steel exterior and electropolished 304 stainless-steel interior chamber and platform surfaces—resistant to corrosion and compatible with standard laboratory disinfectants.
• Optional accessories include universal spring clamps, flask holders (50–5000 mL), tube racks, UV-C germicidal lamp module (254 nm), and O₂ enrichment ports with manual flow shutoff valves.

Sample Compatibility & Compliance

The ZYC-302L accommodates a wide range of vessel formats—including Erlenmeyer flasks (50–2000 mL), test tubes, microtiter plates (with optional adapter), and custom bioreactor vessels—secured via interchangeable mounting fixtures. Its air-bath design eliminates direct contact between heating elements and samples, minimizing localized overheating and ensuring compliance with ISO 13485–aligned quality system requirements for device-related biological testing. The instrument’s temperature stability (±0.3°C at 37°C) and speed repeatability meet ASTM E1249-22 criteria for orbital shaker performance verification. While not certified for GMP manufacturing environments, its data logging capabilities (via USB interface) support GLP-compliant record retention when used in academic, R&D, or QC laboratories adhering to internal SOPs aligned with FDA 21 CFR Part 11 principles (audit trail enabled via external software).

Software & Data Management

Data acquisition is facilitated through a built-in USB port enabling direct download of time-stamped temperature, speed, and runtime logs to standard Windows/Linux systems. Exported files are generated in CSV format and can be imported into spreadsheet or LIMS platforms for trend analysis, calibration validation, or audit documentation. No proprietary software installation is required; raw datasets retain full metadata (date/time stamp, user ID if configured externally, setpoint history). Optional firmware upgrades—distributed via encrypted DRETOP-signed firmware packages—maintain traceability and cybersecurity integrity per IEC 62443-3-3 guidelines for industrial control systems.

Applications

This shaker is routinely deployed in university microbiology labs for aerobic bacterial propagation (e.g., E. coli, Bacillus subtilis), in pharmaceutical R&D for solubility screening and protein expression optimization, and in environmental testing laboratories for BOD incubation and algal growth studies. Its dual-platform configuration allows concurrent execution of control vs. experimental conditions (e.g., temperature gradient studies at 30°C/37°C), fermentation parameter scouting (aeration vs. agitation interdependence), or high-throughput strain library expansion. The RT+5°C to 60°C operating envelope covers standard mesophilic culture protocols as well as thermophilic enzyme characterization—without requiring auxiliary cooling units.

FAQ

Is the ZYC-302L suitable for CO₂-sensitive cell cultures?
No—this model lacks CO₂ regulation or humidity control; it is intended for non-CO₂-dependent microbial or biochemical applications.
Can both shelves operate at different temperatures or speeds?
No—the unit maintains a single uniform air-bath temperature and synchronized oscillation frequency across both platforms.
What is the maximum load capacity per shelf?
Each platform supports up to 15 kg distributed load; recommended flask loading follows DRETOP’s published capacity tables (e.g., 45 × 250 mL flasks or 36 × 500 mL flasks per shelf).
Does the shaker comply with electromagnetic compatibility (EMC) standards for lab environments?
Yes—it meets EN 61326-1:2013 Class A emission limits and EN 61000-4-2/3/4/6 immunity requirements for laboratory instrumentation.
Is remote monitoring or Ethernet connectivity available?
Not natively; networked operation requires third-party IoT gateways interfacing via the USB data export function.
