Maikenuo DHP-160 Temperature-Controlled Incubator

Overview

The Maikenuo DHP-160 is a microprocessor-controlled, forced-air temperature-regulated incubator engineered for stable, repeatable thermal environments in life science laboratories. Designed for routine cell culture, microbial growth, enzyme activity assays, and biological sample conditioning, it operates on the principle of convection-based thermal equilibrium—utilizing a precisely modulated heating element, internal air circulation fan, and high-resolution PID temperature controller to maintain setpoint stability under varying ambient conditions. While humidity control capability is indicated in its classification as a temperature and humidity controlled incubator, technical specifications for humidification performance—including achievable RH range, control accuracy, and steam generation method—are not provided in the manufacturer’s published data. As such, users requiring validated humidity control should confirm operational parameters with the distributor prior to deployment in GLP or ISO 17025-compliant workflows.

Key Features

• Microprocessor-based digital temperature controller with LED display for real-time setpoint and chamber temperature readout
• Forced-air convection system ensuring improved thermal homogeneity compared to static-air designs
• Double-layer insulated chamber door with magnetic seal to minimize heat loss and external condensation
• Stainless steel interior chamber (304 grade) for corrosion resistance, ease of decontamination, and compliance with biosafety cleaning protocols
• Over-temperature protection circuit with independent mechanical safety cutoff to prevent thermal runaway
• Adjustable stainless steel shelving (standard configuration: 2 shelves, load capacity ≤15 kg per shelf)
• Compliance-ready design supporting documentation traceability for internal lab quality systems

Sample Compatibility & Compliance

The DHP-160 accommodates standard laboratory vessels including Petri dishes, multi-well plates (6–96-well), Erlenmeyer flasks (up to 2 L), and tissue culture flasks (T25–T225). Its chamber dimensions (approx. 500 × 450 × 700 mm W×D×H, inferred from model-series benchmarks) support typical benchtop workflow integration. The unit meets basic electrical safety requirements per GB 4793.1–2007 (equivalent to IEC 61010-1) for laboratory equipment. It is not certified to UL 61010-1, EN 61010-1, or FDA 21 CFR Part 11 out-of-the-box; however, its architecture permits integration into audit-trail-enabled environmental monitoring systems when paired with external data loggers compliant with ISO/IEC 17025 clause 7.7. Humidity-related applications (e.g., fungal culture, seed germination studies) require third-party validation due to absence of factory-reported RH performance metrics.

Software & Data Management

The DHP-160 operates via embedded firmware without native PC connectivity or software interface. All parameter setting and status monitoring occur locally via front-panel controls. For regulated environments, users may integrate optional external USB or Ethernet-enabled temperature data loggers (e.g., Omega OM-DAQPRO-5300, Testo 177-T4) that provide time-stamped, password-protected records compliant with ALCOA+ principles. Audit trail functionality, electronic signatures, and user access levels must be implemented at the data acquisition layer—not within the incubator’s base firmware. Firmware updates are not supported remotely; service interventions require authorized technician access.

Applications

• Bacterial and yeast cultivation in microbiology QC labs (e.g., total viable count, antimicrobial susceptibility testing per CLSI M07)
• Mammalian and insect cell propagation during upstream bioprocessing development
• Enzyme kinetics studies requiring precise thermal stabilization (e.g., amylase, protease, lipase activity assays)
• Material biocompatibility testing per ISO 10993-5 (cytotoxicity screening under controlled thermal exposure)
• Seed viability and germination rate assessment in agricultural research settings
• Short-term storage of temperature-sensitive reagents (e.g., restriction enzymes, antibodies) where refrigerated incubation is preferred over cold-room cycling

FAQ

Does the DHP-160 include humidity control functionality?

The product classification references humidity control capability, but no verified RH operating range, accuracy, or humidification mechanism (e.g., ultrasonic, steam injection) is published. Confirm technical implementation with Maikenuo’s authorized distributor before specifying for hygroscopic or moisture-dependent protocols.
Is the unit suitable for GMP-regulated environments?

It may be deployed in GMP facilities for non-critical process steps (e.g., pre-incubation of media), provided temperature mapping, periodic calibration (traceable to NIST standards), and preventive maintenance logs are maintained per Annex 15 and EU GMP Chapter 3 requirements.
What is the warranty coverage and service support structure?

Maikenuo provides a 12-month limited warranty covering defects in materials and workmanship under normal laboratory use. Field service is coordinated through authorized regional distributors; response time and spare parts availability vary by geography and require advance service agreement registration.
Can the incubator be calibrated internally?

No built-in calibration mode exists. Users must perform external verification using a Class A PT100 probe or equivalent NIST-traceable reference thermometer, following SOPs aligned with ISO/IEC 17025 clause 6.5. Calibration frequency should reflect risk assessment outcomes (e.g., daily for critical QC processes, quarterly for R&D use).
