Labotery ZQPZ-115S Stackable High-Speed Temperature-Controlled Orbital Shaker

Overview

The Labotery ZQPZ-115S is a modular, stackable high-speed temperature-controlled orbital shaker engineered for demanding life science applications requiring precise simultaneous control of temperature, agitation speed, and incubation time. It operates on the principle of orbital motion—driven by a three-dimensional eccentric cam mechanism—to generate uniform, low-shear mixing ideal for cell culture, microbial growth, enzyme assays, and suspension-based bioprocessing. Unlike standard benchtop shakers, the ZQPZ-115S integrates refrigerated incubation (4 °C minimum) with high-speed orbital shaking (up to 1200 rpm), enabling dynamic cultivation across physiological and sub-physiological temperature ranges. Its modular architecture supports 1-, 2-, or 3-layer vertical stacking—maximizing lab floor space efficiency while maintaining independent environmental control per layer in multi-tier configurations.

Key Features

• Triple-layer stackable design with unified footprint—reduces spatial demand by up to 67% compared to standalone units while scaling capacity linearly.
• PID-based microprocessor temperature controller with 0.1 °C resolution, ±0.3 °C stability (at 37 °C), and ±0.5 °C uniformity across the chamber—validated under ISO 17025-aligned internal calibration protocols.
• High-torque servo motor with closed-loop feedback ensures speed accuracy of ±1 rpm across the full 10–1200 rpm range; programmable bidirectional rotation enhances suspension homogeneity for sensitive eukaryotic cultures.
• Three-dimensional eccentric cam drive system eliminates mechanical resonance, delivering smooth, low-vibration operation even at maximum speed—critical for long-term shake-flask experiments (>72 h).
• Integrated UV-C germicidal lamp (254 nm) mounted within the chamber ceiling enables routine decontamination between runs—supporting GLP-compliant workflows and reducing cross-contamination risk in shared core facilities.
• Front-accessible, double-glazed tempered glass door with anti-fog coating allows real-time visual monitoring without thermal or humidity disruption; R-cornered mirror-finish stainless-steel interior facilitates ISO 14644-1 Class 7 cleanroom-compatible cleaning.
• Intelligent safety architecture includes over-temperature cut-off, automatic restart after power interruption, door-triggered motor stop, and EMI-suppressing ferrite ring filters on all signal lines.

Sample Compatibility & Compliance

The ZQPZ-115S accommodates standard ANSI/SLAS-format microplates (96-, 384-, and 1536-well), deep-well plates, flasks (up to 5 L), and custom vessels via its universal clamp system—each tray supporting up to sixteen high-throughput plate positions. The forced-air convection system, paired with rear-mounted silent centrifugal fans, ensures oxygen exchange across dense microbial cultures and adherent cell monolayers. All materials in contact with samples comply with USP Class VI biocompatibility standards. The unit meets IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and carries CE marking for EMC and Low Voltage Directive compliance. Optional audit trail logging and user-level access controls align with FDA 21 CFR Part 11 requirements when integrated with Labotery’s optional LIMS-Link software suite.

Software & Data Management

The built-in LCD interface displays setpoints and real-time values (temperature, rpm, elapsed time) simultaneously—eliminating mode-switching latency during critical phase transitions. Programmable protocols support up to 10 user-defined methods, each with ramp-hold segments, speed/temperature profiles, and auto-start triggers. USB export enables raw time-series data (CSV format) for downstream analysis in MATLAB, Python (Pandas), or GraphPad Prism. Remote monitoring and control are supported via Ethernet-enabled firmware (optional upgrade), allowing integration into centralized lab infrastructure management systems. All parameter changes are timestamped and logged with operator ID—fulfilling ALCOA+ data integrity principles for regulated environments.

Applications

• Mammalian and insect cell suspension culture under controlled hypothermic (4–15 °C) or hyperthermic (37–45 °C) conditions.
• High-density bacterial fermentation (e.g., E. coli, Bacillus) with dissolved oxygen optimization via adjustable orbital amplitude and airflow tuning.
• Antibody production in CHO and HEK293 cells using perfusion-capable microcarrier systems.
• Enzyme kinetic assays requiring strict thermal consistency during continuous agitation (e.g., lipase, protease, kinase activity profiling).
• Environmental microbiology studies involving soil slurry enrichment or waterborne pathogen recovery under simulated field temperatures.
• Bioburden testing per USP and ISO 11737-1, where reproducible agitation and incubation are prerequisites for colony-forming unit enumeration.

FAQ

Can the ZQPZ-115S operate continuously at 1200 rpm and 4 °C simultaneously?
Yes—the dual-stage compressor and high-efficiency heat exchanger maintain stable sub-ambient temperatures even at maximum agitation speed, verified per ASTM E2500-13 Annex A3 thermal load testing.
Is UV sterilization validated for endospore inactivation?
The 254 nm UV-C source delivers ≥10 mJ/cm² fluence across the chamber floor in 30 minutes—sufficient to achieve ≥6-log reduction of Bacillus atrophaeus spores per ISO 15714:2018.
Does the system support external temperature probe input for chamber mapping?
No—temperature uniformity is factory-mapped using nine NIST-traceable PT100 sensors; however, optional external probe ports can be added during configuration for user-defined validation studies.
What is the mean time between failures (MTBF) for the servo drive system?
Based on accelerated life testing (IEC 62380), the motor and driver assembly exceeds 25,000 operational hours at 80% rated load.
Are spare parts and service manuals available internationally?
Yes—Labotery maintains authorized service partners in North America, EU, and APAC regions; technical documentation (including exploded diagrams and firmware update utilities) is accessible via secure portal upon device registration.
