CZGY THZ-200B Benchtop Full-Temperature Orbital Shaker

Overview

The CZGY THZ-200B Benchtop Full-Temperature Orbital Shaker is an engineered platform for precise temperature-controlled agitation of biological and biochemical samples in research and quality control laboratories. Utilizing a robust air-bath heating system and a balanced orbital drive mechanism, the instrument maintains uniform thermal distribution across the shaking surface while delivering consistent, low-shear mixing—critical for cell culture expansion, microbial growth studies, enzyme kinetics, and suspension-based assays. Unlike water-bath shakers, the air-bath design eliminates liquid contamination risks and simplifies maintenance, making it ideal for routine use in GLP-compliant labs, academic core facilities, and pharmaceutical QC environments. Its operational range—from 5 °C (below ambient) to 60 °C—enables applications spanning psychrophilic organism cultivation, mesophilic fermentation, and thermally accelerated stability testing.

Key Features

• Stable orbital motion with adjustable speed (40–300 rpm) and fixed 26 mm amplitude, optimized for homogeneous suspension without foaming or shear-induced cell lysis
• Precision PID temperature control with ±0.5 °C accuracy across the full 5–60 °C range, verified via internal PT100 sensor and calibrated airflow management
• Single-tier stainless steel shaking plate (440 × 350 mm), compatible with standard flasks (up to 5 L), test tubes, microplates, and culture bags using universal spring clamps
• Extended programmable timer supporting dual units: minutes (1–9999) or hours (1–9999), with auto-shutdown and memory retention after power interruption
• Integrated UV-C sterilization module and LED illumination—both factory-standard—to support aseptic handling and real-time visual monitoring during incubation
• Robust mechanical architecture: cold-rolled steel chassis with epoxy powder coating, corrosion-resistant mirror-finish 304 stainless steel chamber interior, and brushless DC motor for long-term reliability

Sample Compatibility & Compliance

The THZ-200B accommodates a broad spectrum of sample containers—including Erlenmeyer flasks (50 mL to 5 L), centrifuge tubes, Petri dishes, multi-well plates, and custom bioreactor vessels—without requiring adapter kits. Its orbital geometry ensures minimal vortexing and maximal oxygen transfer in aerobic cultures. The unit meets general electrical safety requirements per IEC 61010-1 and is constructed to support ISO/IEC 17025 laboratory accreditation workflows. While not certified for medical device manufacturing under FDA 21 CFR Part 11 out-of-the-box, its programmable parameters, audit-ready timer logs, and non-volatile settings storage enable traceable operation when integrated into validated SOPs compliant with USP , ASTM E2500, and EU GMP Annex 11 frameworks.

Software & Data Management

The THZ-200B operates via an intuitive front-panel interface with digital LED display for simultaneous readout of setpoint temperature, actual temperature, rotational speed, and remaining time. No external software is required for basic operation; however, optional RS-485 serial output (available on request) allows integration with LabArchives, LabVantage, or custom SCADA systems for centralized parameter logging and remote status monitoring. All timing events and temperature deviations are recorded in non-volatile memory, supporting retrospective review during internal audits or regulatory inspections. Firmware supports user-defined profiles (up to 10 saved programs), facilitating repeatable experimental conditions across shifts and operators.

Applications

• Mammalian and insect cell line propagation in suspension culture systems
• Bacterial and yeast fermentation optimization under controlled thermal gradients
• Antibiotic susceptibility testing and MIC determination in CLSI-compliant protocols
• Protein solubilization and antigen-antibody binding kinetics in immunoassay development
• Environmental microbiology: enrichment of soil/water isolates at ecologically relevant temperatures
• Stability assessment of biologics and excipient formulations per ICH Q5C guidelines
• Preparation of homogeneous suspensions for downstream analysis (e.g., flow cytometry, HPLC sample injection)

FAQ

Can the THZ-200B operate below ambient temperature?
Yes—the unit achieves a minimum setpoint of 5 °C regardless of room temperature, enabled by active cooling via thermoelectric elements and regulated airflow.
Is the shaking motion configurable between orbital and reciprocating modes?
Orbital is standard; reciprocating motion is available as a factory-configured option—contact technical support prior to order to confirm mechanical compatibility and lead time.
Does the UV sterilization function meet ISO 15883 standards for lab equipment decontamination?
The built-in UV-C lamp (254 nm) provides surface-level microbial reduction per ISO 15883-1 Annex B guidance but is not validated for complete sterilization of enclosed chambers; supplemental ethanol wipe-down is recommended for critical applications.
What is the maximum flask volume supported on the standard plate?
A single 5 L Erlenmeyer flask may be accommodated; for optimal balance and longevity, loading should not exceed 70% of total plate area or 15 kg distributed mass.
Are calibration certificates provided with shipment?
NIST-traceable temperature and speed calibration reports are available upon request at additional cost and require 5 business days for issuance pre-shipment.
