DRETOP ZYL-5036 Air-Bath Constant-Temperature Orbital/Reciprocal Shaker

Overview

The DRETOP ZYL-5036 Air-Bath Constant-Temperature Orbital/Reciprocal Shaker is an engineered platform for precise, reproducible incubation and mixing of biological and biochemical samples under controlled thermal and mechanical conditions. Unlike water-bath shakers, this air-bath system employs forced-air convection—driven by a high-efficiency internal blower and uniform airflow ducting—to achieve rapid thermal equilibration and exceptional temperature homogeneity (±0.5 °C) across the entire chamber volume (≥98 L). Its dual-mode oscillation capability (orbital and reciprocal) supports diverse culture formats including Erlenmeyer flasks, test tubes, microtiter plates, and culture bottles. Designed for continuous operation in academic laboratories, clinical research units, pharmaceutical QC labs, and environmental testing facilities, the ZYL-5036 complies with fundamental operational safety and stability requirements aligned with ISO 13485–informed lab equipment practices and supports GLP-compliant documentation when paired with optional data logging accessories.

Key Features

• Microprocessor-based PID temperature and speed control system with real-time LED dual-digit display for simultaneous monitoring of setpoint and actual values (temperature in °C, speed in rpm, timer in minutes)
• DC permanent-magnet motor delivering stable torque output across the full 40–300 rpm range; speed regulation accuracy ±1 rpm; no carbon brushes, zero maintenance requirement
• PT100 platinum resistance temperature sensor integrated into chamber wall for high-fidelity thermal feedback and responsive correction
• Intelligent safety architecture: independent over-temperature cutoff (audible/visual alarm), motor overheat protection, and automatic power disconnection upon thermal runaway or sensor failure
• Soft-start circuitry prevents abrupt acceleration—minimizing liquid splashing and ensuring sample integrity during flask or plate-based cultures
• Parameter lock function enables password-protected configuration to prevent unauthorized modification during unattended operation
• Power-failure recovery mode retains last operational settings and resumes pre-interruption protocol automatically after mains restoration
• Stainless-steel interior chamber and reinforced structural frame ensure corrosion resistance, long-term dimensional stability, and compatibility with common laboratory disinfectants

Sample Compatibility & Compliance

The ZYL-5036 accommodates standard laboratory vessels up to 5 L capacity, including conical flasks (100–2000 mL), culture tubes, deep-well plates, and enzymatic assay trays. Its adjustable spring clamps—constructed from medical-grade stainless steel—provide secure fixation without deformation or slippage. The unit meets CE-marking prerequisites for electromagnetic compatibility (EMC Directive 2014/30/EU) and low-voltage safety (LVD Directive 2014/35/EU). While not certified to IEC 61010-1 as a standalone medical device, its design principles align with risk management frameworks referenced in ISO 14971 for laboratory instrumentation used in diagnostic development and bioprocess validation.

Software & Data Management

The base configuration operates via front-panel controls with no embedded software stack. Optional USB data-logging module enables time-stamped recording of temperature, speed, and elapsed time at user-defined intervals (1–60 sec resolution), generating CSV-formatted files compatible with Excel, MATLAB, and LabArchives. When deployed with the optional color touchscreen interface, the system supports audit-trail-enabled parameter logging per FDA 21 CFR Part 11 guidelines—provided external validation protocols are executed by the end user. Wireless monitoring (Wi-Fi or Bluetooth) and thermal printing modules are available as field-upgradable add-ons for paperless recordkeeping in regulated environments.

Applications

• Microbial and mammalian cell culture propagation under defined aeration and thermal conditions
• Enzyme kinetics assays requiring consistent agitation and temperature stabilization
• Solubility and dissolution testing of active pharmaceutical ingredients (APIs) per USP & Ph. Eur. methods
• Environmental sample enrichment (e.g., coliform detection in water matrices)
• Protein expression optimization in shake-flask bioreactors
• Antibiotic susceptibility testing using broth microdilution formats
• Preparative-scale buffer equilibration and reagent homogenization

FAQ

What is the maximum flask size supported on the ZYL-5036 platform?

Standard configurations accommodate up to 2 L Erlenmeyer flasks; with optional extended-clamp kits, 5 L vessels may be secured under orbital mode at ≤150 rpm.
Does the unit support programmable multi-step protocols?

Yes—via optional touchscreen controller, users may define up to 16 sequential segments combining distinct temperature setpoints, speeds, and dwell times.
Is calibration documentation provided with the instrument?

Factory calibration certificates for temperature (at 37 °C and 50 °C) and speed (at 100 rpm and 250 rpm) are included; traceability to national standards (NIM, China) is stated.
Can the ZYL-5036 operate continuously for 72+ hours?

Rated for uninterrupted duty cycle at ≤250 rpm and ≤45 °C ambient; thermal derating applies above 45 °C chamber setpoint.
What maintenance is required for long-term reliability?

Annual inspection of fan assembly, motor brushless commutation integrity, and PID controller firmware version is recommended; no routine lubrication or consumable replacement is needed.
