MKN B Series Intelligent Plant Growth Chamber

Overview

The MKN B Series Intelligent Plant Growth Chamber is a precision-controlled environmental simulation system engineered for reproducible, long-term cultivation of plants, algae, fungi, and phototrophic microorganisms under defined temperature, humidity, and light conditions. Based on the principle of active climate regulation—integrating Peltier-assisted or compressor-based thermoelectric cooling/heating, resistive humidification/dehumidification, and spectrally tunable illumination—the chamber maintains stable setpoints across its 160 L working volume. Designed for compliance with standard laboratory environmental conditioning protocols, it supports ISO/IEC 17025-aligned experimental workflows in plant physiology, crop science, seed germination studies, circadian rhythm research, and pre-clinical botanical assay development.

Key Features

• Microprocessor-based dual-loop PID control for independent regulation of temperature, relative humidity, and light intensity—ensuring stability within ±1 °C and ±5 %RH under steady-state operation.
• High-efficiency polyurethane insulation (≥50 mm thickness) minimizes thermal bridging and energy consumption while maintaining uniform internal climate distribution.
• Forced-air circulation system with rear-mounted centrifugal blower and perforated baffle design achieves ≤±0.8 °C spatial temperature uniformity (measured per ASTM E1395-22 at 9 reference points).
• Double-layer tempered glass door with anti-fog coating and magnetic seal enables clear observation without compromising chamber integrity or thermal load.
• Stainless steel interior (AISI 304 grade) and rounded chamber corners facilitate cleaning, sterilization, and adherence to GLP-compliant hygiene standards.
• Compressor protection circuitry includes automatic restart delay (≥3 min), phase-loss detection, and high-pressure cutoff—extending service life and reducing unplanned downtime.

Sample Compatibility & Compliance

The chamber accommodates standard-sized growth trays (up to 400 × 300 mm footprint), multi-tier shelving configurations, and modular pot racks. It supports both sterile and non-sterile cultivation modes and is compatible with common plant tissue culture vessels, petri dishes, hydroponic modules, and microcosm setups. The system meets structural and electrical safety requirements per IEC 61010-1:2010 and complies with electromagnetic compatibility standards EN 61326-1:2013. While not certified for GMP manufacturing environments, its logging-capable controller architecture supports audit-ready documentation for academic, regulatory, and industrial R&D applications governed by ISO 14644-1 (cleanroom classification), USP , and OECD Test Guidelines 208 (terrestrial plant toxicity).

Software & Data Management

The embedded controller features real-time data logging with timestamped storage of temperature, humidity, and illumination profiles (minimum interval: 1 minute; onboard memory: 30 days at default sampling). Optional RS-485 or USB-to-serial interface enables integration with LabVIEW, MATLAB, or custom SCADA systems via Modbus RTU protocol. Data export is supported in CSV format for post-processing in statistical software (e.g., R, Python pandas). Audit trail functionality—including user login history, parameter change logs, and alarm event records—meets basic requirements for 21 CFR Part 11 Annex 11 readiness when paired with validated third-party software solutions.

Applications

• Controlled-environment phenotyping of model species (Arabidopsis thaliana, Oryza sativa) under diurnal light/dark cycles.
• Seed viability and germination rate assessment per ISTA Rules and AOSA Standards.
• Cultivation of light-dependent cyanobacteria (e.g., Synechocystis sp. PCC 6803) for biofuel precursor synthesis.
• Long-term stress response experiments involving drought, heat, or photoinhibition treatments.
• Pre-acclimatization of tissue-cultured plantlets prior to greenhouse transfer.
• Environmental simulation for ecotoxicology testing of agrochemicals under tiered exposure scenarios.

FAQ

What is the maximum illumination intensity and spectral range?
The chamber delivers ≥5000 lux at shelf level using adjustable white-light sources. Spectral output depends on lamp type (standard configuration: cool-white fluorescent or broad-spectrum LED); optional narrow-band LED modules (450 nm blue, 660 nm red) are available upon request.
Can humidity be maintained below 50% RH?
No—the standard humidification system is designed for 50–90% RH operation. Sub-50% RH requires external desiccant-based dehumidification or nitrogen purge integration, which is not supported natively.
Is remote monitoring supported out-of-the-box?
Basic local data export is included; Ethernet/WiFi connectivity and cloud-based dashboards require optional hardware add-ons and firmware upgrades.
What maintenance intervals are recommended?
Compressor oil inspection every 24 months; condensate drain line cleaning quarterly; air filter replacement every 6 months; calibration verification annually using NIST-traceable probes.
Does the unit comply with FDA or CE marking requirements?
It carries CE marking per Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. FDA registration is not applicable as this is a research-grade instrument, not a medical device.
