Overview
The MEMMERT HPP108 Photoperiodic Climate Chamber is a precision-engineered, semiconductor-cooled environmental simulation system designed for reproducible long-term biological and botanical studies requiring strict control of temperature, relative humidity, and spectrally tunable illumination. Unlike conventional compressor-based climate chambers, the HPP108 employs solid-state Peltier technology for both heating and cooling—enabling ultra-low vibration operation (< 0.5 µm RMS), critical for sensitive applications such as Drosophila development, seed germination kinetics, photomorphogenesis assays, and circadian rhythm research. Its measurement architecture integrates Class A PT100 four-wire temperature sensors and capacitive humidity transducers, compliant with DIN 12 880:2007-05 for thermal stability verification. The chamber delivers ±0.1 °C temporal temperature stability and ≤±0.4 °C spatial uniformity at key setpoints (10 °C and 37 °C), ensuring GLP-aligned experimental integrity across extended incubation cycles.
Key Features
- Photobiologically optimized LED illumination system with two selectable spectral modes: cool white (5500 K) and dual-color blend (5500 K + 2700 K), covering the full visible spectrum (380–780 nm)
- Digitally adjustable light intensity in 10% increments, up to 10,000 lux at 10 cm distance (measured per ISO/CIE standards)
- Ultra-low mechanical vibration profile achieved via Peltier thermoelectric modules—eliminating compressor-induced microtremors that disrupt embryonic development or insect locomotion studies
- Stainless steel interior (AISI 304) with five adjustable, perforated stainless steel shelves; external housing features embossed stainless steel front and galvanized steel rear panel
- Intelligent humidity management: self-suctioning distilled water reservoir, thermally sterilized steam generation, and condensation-suppressing rapid recovery algorithm (10–90 %RH range; 10–85 %RH when illumination active)
- Triple-layer safety architecture: hardware-level overtemperature protection (Class 3.3 per DIN EN 61000-6-2), automatic shutdown relay, and real-time sensor diagnostics with visual/audible alarms
Sample Compatibility & Compliance
The HPP108 supports diverse biological sample formats—including Petri dishes, multiwell plates, growth trays, and ventilated insect cages—without compromising environmental fidelity. Its internal volume (108 L), dimensions (W 560 × H 480 × D 400 mm), and removable shelves accommodate standard labware while maintaining laminar airflow distribution. Regulatory compliance includes adherence to DIN 12 880:2007-05 (climate chamber performance testing), IEC 61000-6-2 (EMC immunity), and EN 61010-1 (safety requirements for laboratory equipment). For regulated environments, the built-in logging system meets ALCOA+ data integrity principles, supporting audit trails required under FDA 21 CFR Part 11 when paired with validated software interfaces.
Software & Data Management
Embedded firmware provides comprehensive environmental logging: 1024 KB internal memory stores timestamped values for temperature, RH, illumination status, alarms, and diagnostic events at 1-minute intervals—supporting up to 3 months of continuous recording. Data export is enabled via parallel port (PCL3-compatible inkjet printers) or USB-to-parallel adapters. Optional MEMoryCard XL software enables remote configuration of up to 40-stage weekly programs with independent ramp/soak profiles for temperature, humidity, and light intensity—including weekend-only or diurnal cycle scheduling. On-device calibration is performed without external PCs: 3-point temperature and 2-point humidity (20 %RH / 90 %RH) adjustments are accessible via intuitive multilingual UI (German, English, Spanish, French, Italian).
Applications
- Plant physiology: photoperiod-controlled phenotyping, vernalization studies, and stress response assays under defined spectral irradiance
- Insect rearing: Drosophila melanogaster, Tribolium castaneum, and other model organisms requiring vibration-free incubation during pupation and eclosion
- Seed science: standardized germination testing per ISTA protocols with synchronized light/dark transitions
- Microbial ecology: humidity-stable fungal culture maintenance and spore viability assessment
- Pharmaceutical stability: ICH Q1B-compliant photostability screening under controlled irradiance conditions
- Academic teaching labs: modular climate experimentation for undergraduate biology and environmental science curricula
FAQ
What is the maximum illumination intensity achievable, and at what distance is it measured?
The LED system delivers up to 10,000 lux at a distance of 10 cm from the light source, calibrated using traceable photometric standards.
Can the HPP108 operate continuously at 40 °C with 85 %RH and full illumination?
Yes—the semiconductor cooling system maintains stable operation within the specified operating envelope (10–40 °C / 10–85 %RH with light), even under high ambient temperatures (up to 35 °C room temperature).
Is the humidity system compatible with deionized or reverse-osmosis water?
Only distilled or demineralized water (conductivity < 5 µS/cm) is permitted to prevent mineral scaling and sensor drift; RO water may be used if conductivity is verified.
Does the device support 21 CFR Part 11 compliance out of the box?
The HPP108 provides foundational data integrity features (audit trail, electronic signatures via optional software, and secure user access levels); full Part 11 validation requires site-specific IQ/OQ/PQ documentation and third-party software qualification.
How many shelf positions are adjustable, and what is the load capacity per shelf?
Five perforated stainless steel shelves are included, each rated for 15 kg uniformly distributed load; shelf spacing is freely configurable within the 480 mm internal height.
