Labotery ZQPW-70 Full-Temperature Orbital Shaking Incubator

Overview

The Labotery ZQPW-70 Full-Temperature Orbital Shaking Incubator is an engineered platform for precise, reproducible cultivation of microbial, mammalian, and suspension cell cultures under controlled temperature and agitation conditions. It integrates orbital shaking mechanics—based on a constant-diameter circular motion (26 mm orbit)—with active refrigeration and heating to maintain stable thermal environments across the full biologically relevant range of 4°C to 65°C. Unlike ambient-only shakers, the ZQPW-70 employs a high-efficiency, imported CFC-free compressor coupled with a thermally optimized heat dissipation architecture, enabling sustained low-temperature operation without compressor thermal shutdown. Its forced-air convection system—driven by a centrifugal air duct—ensures uniform temperature distribution (±0.5°C at 37°C), critical for kinetic consistency in growth curve studies, enzyme assays, and solubility screening. Designed for GLP-compliant labs, the unit supports traceable process control through PID-based microprocessor regulation (0.1°C resolution) and non-volatile memory retention.

Key Features

• Brushless DC motor drive delivering precise speed control (10–400 rpm, ±1 rpm accuracy), extended service life, and zero maintenance requirements.
• Multi-axis integrated eccentric cam mechanism ensures mechanical stability, minimal vibration transmission, and long-term operational reliability.
• PID-controlled temperature regulation with real-time feedback, achieving ±0.3°C stability at setpoint (tested at 37°C, empty chamber).
• Intelligent door interlock system halts oscillation immediately upon door opening—preventing sample disturbance and operator exposure.
• Three programmable motion modes: continuous forward rotation, alternating forward/reverse cycling, and static incubation—enabling simulation of shear-sensitive or sedimentation-prone culture conditions.
• Full-cycle programmability: users define multi-segment protocols with independent speed, direction, dwell time, and temperature setpoints per segment; timing configurable from 1 minute to 9999 minutes (or hours).
• LCD interface with intuitive navigation; optional upgrade path to true-color capacitive touchscreen controller supporting graphical protocol editing and USB data export.
• Dual lighting system: white LED illumination for routine visual inspection and a 254 nm UV-C germicidal lamp for periodic chamber decontamination (UV dose calibrated per IEC 62471).
• Tempered double-layer hollow glass door with Ø30 mm access port for sensor insertion, gas exchange tubing, or pH/DO probe integration—supporting aerobic and microaerophilic workflows.

Sample Compatibility & Compliance

The ZQPW-70 accommodates standard laboratory vessels including Erlenmeyer flasks (100–1000 mL), culture tubes, and deep-well plates via its universal spring clamp system (standard configuration: 100 mL × 25, 250 mL × 20, etc.). The 520 × 430 mm stainless steel working shelf is electropolished for corrosion resistance and ease of decontamination. All electrical components comply with IEC 61010-1 safety standards for laboratory equipment. While not certified for ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, the system’s audit-ready features—including timestamped event logging (door opens, alarms, mode changes), power-fail recovery, and non-volatile parameter storage—facilitate integration into GMP/GLP environments when paired with validated SOPs and external electronic lab notebook (ELN) systems.

Software & Data Management

The base LCD controller logs operational events (e.g., temperature deviations, speed anomalies, door actuation) with timestamps and retains them across power cycles. Optional touchscreen firmware adds CSV export capability via USB port, enabling direct import into LIMS or statistical analysis platforms (e.g., JMP, GraphPad Prism). Protocol files are stored internally with versioned naming; no cloud connectivity or remote access is implemented—ensuring data sovereignty and alignment with institutional IT security policies. Firmware updates are performed offline using signed binary packages distributed via Labotery’s secure customer portal.

Applications

• Microbial growth kinetics (E. coli, yeast, Bacillus spp.) under variable temperature and aeration regimes.
• Mammalian suspension cell expansion in serum-free media, where gentle orbital motion minimizes shear stress versus vortexing.
• Protein expression optimization in autoinduction media requiring precise thermal ramping during induction phase.
• Biochemical assay development involving temperature-dependent enzyme activity profiling across 4–65°C.
• Environmental microbiology studies simulating seasonal temperature shifts in aquatic or soil-derived isolates.
• Preparation of homogeneous suspensions for downstream applications including flow cytometry, qPCR template generation, and metabolite extraction.

FAQ

What is the minimum operating temperature, and can it sustain 4°C with continuous shaking?
Yes—the ZQPW-70 achieves and maintains 4°C under continuous 10–400 rpm operation, verified per ISO 8570:2020 thermal performance testing at 20°C ambient.
Is the UV lamp intensity calibrated, and what is its rated lifetime?
The 254 nm low-pressure mercury UV-C lamp is rated for 5,000 hours of operation; intensity is factory-verified using NIST-traceable radiometry and documented in the Certificate of Conformance.
Can the shaker accommodate baffled flasks for improved oxygen transfer?
Yes—baffled flasks up to 1000 mL fit within the standard clamp configuration; maximum fill volume recommendations follow ASTM D5257 guidelines for orbital shake flask aeration efficiency.
Does the system support external temperature probe input for vessel-specific monitoring?
No native analog input is provided; however, the Ø30 mm access port allows integration of third-party PT100 or thermocouple probes connected to external dataloggers.
What documentation is supplied for regulatory submissions?
Each unit ships with a Factory Calibration Report (temperature uniformity/stability, speed accuracy), Electrical Safety Test Certificate (IEC 61010-1), and Material Declaration (RoHS/REACH compliance statement).
