Overview
The Maikenuo MK-150A Biochemical Incubator is a precision-controlled, dual-mode (heating and refrigeration) environmental chamber engineered for stable, long-term cultivation of biological samples under defined thermal conditions. Based on Peltier-assisted or compressor-based active cooling combined with resistive heating elements and PID-regulated microprocessor control, the unit maintains consistent temperature profiles across its stainless-steel interior chamber—critical for reproducible results in microbiological growth, enzymatic assays, cell culture pre-incubation, and biochemical stability testing. Designed to meet foundational requirements of ISO/IEC 17025-accredited laboratories and GLP-compliant workflows, it supports applications where thermal deviation must remain within ±1 °C over extended durations, including shelf-life studies, QC sample conditioning, and educational laboratory instruction in life sciences curricula.
Key Features
- Stainless-steel inner chamber and powder-coated carbon steel exterior for corrosion resistance and structural integrity
- Polyurethane foam insulation (≥40 mm thickness) ensuring low thermal leakage and energy-efficient operation
- Micro-circulation fan system mounted at the top for uniform air distribution and minimized vertical temperature gradients
- LED digital display with real-time temperature readout and intuitive keypad interface for setpoint adjustment and status monitoring
- Compressor protection circuitry incorporating power-off delay and restart inhibition to extend refrigeration system service life
- Integrated interior lighting (LED) for non-invasive visual inspection without opening the door
- Robust architecture rated for continuous 24/7 operation under ambient conditions up to 40 °C and 85% relative humidity
Sample Compatibility & Compliance
The MK-150A accommodates standard Petri dishes, multi-well plates, test tubes (up to 16 mm diameter), Erlenmeyer flasks (≤500 mL), and culture bottles. Its temperature stability profile complies with ASTM E2928-22 (Standard Practice for Calibration and Verification of Temperature-Controlled Chambers) and aligns with general-purpose incubation requirements outlined in USP and ISO 20387:2018 (Biobanking). While not certified for sterile processing or Class II biosafety containment, it meets essential performance criteria for non-sterile, low-risk biological work—including bacterial colony enumeration (ISO 4833-1), yeast/mold enumeration (ISO 21527-1), and enzyme activity assays conducted per ICH Q5C guidelines. The unit operates within the regulatory scope of FDA 21 CFR Part 11 when paired with validated external data logging systems.
Software & Data Management
The MK-150A operates via embedded firmware with no proprietary software dependency. All operational parameters—including setpoint, real-time temperature, elapsed run time, and alarm status—are accessible through the front-panel LED interface. For traceable recordkeeping, users may integrate third-party USB or RS-232 data loggers compliant with ISO/IEC 17025 Annex A.2 (data integrity controls), enabling audit-ready temperature trending, calibration verification logs, and electronic signature support when deployed in GxP environments. Firmware supports password-protected parameter locking to prevent unauthorized adjustments during routine QC procedures.
Applications
- Bacterial and fungal culture propagation in clinical, environmental, and food microbiology labs
- Enzyme kinetics and protein stability studies requiring controlled thermal ramping or hold phases
- Pre-incubation of reagents and media prior to PCR, ELISA, or Western blot workflows
- Environmental simulation for biodegradation testing (e.g., OECD 301 series)
- Seed germination and plant tissue culture initiation under standardized thermal regimes
- Quality control of raw materials and finished products in pharmaceutical and nutraceutical manufacturing
- Undergraduate and graduate teaching laboratories supporting curriculum-aligned experiments in molecular biology and biochemistry
FAQ
Does the MK-150A support programmable temperature ramps or multi-step profiles?
No—this model features single-setpoint PID control only. For gradient protocols, consider externally interfaced programmable controllers or upgraded models with multi-segment scheduling capability.
Is the incubator suitable for CO₂-dependent cell cultures?
No—CO₂ regulation requires gas mixing, humidification, and infrared sensing subsystems not present in this configuration. Use dedicated CO₂ incubators for mammalian cell work.
What calibration documentation is provided with shipment?
Each unit ships with a factory calibration certificate verifying temperature uniformity and accuracy at three points (15 °C, 37 °C, and 45 °C) per ISO 17025 traceable standards.
Can the unit be validated for IQ/OQ/PQ in regulated environments?
Yes—protocol templates and URS alignment guidance are available upon request; validation must be performed by qualified personnel using NIST-traceable reference thermometers.
What is the warranty coverage and service response timeline?
One-year limited warranty covering parts and labor for defects in materials or workmanship. On-site technical support is available within 5 business days in major Chinese Tier-1 cities; remote diagnostics and spare-part dispatch are standard globally.
