Memmert HCP108 Climate Chamber

Overview

The Memmert HCP108 Climate Chamber is a precision-engineered, fully stainless steel environmental test chamber designed for reproducible long-term conditioning of sensitive samples under tightly controlled temperature and relative humidity (RH) conditions. Based on forced-air convection with laminar airflow distribution and six-sided heating architecture, the HCP108 employs a closed-loop dynamic humidity control system—fed by distilled water from an external reservoir via a calibrated peristaltic pump—to maintain stable RH setpoints across its operational range of 20–95 % RH. Its thermally optimized aluminum heat-distribution layer ensures exceptional temperature uniformity (±0.5 °C at 90 °C), while the dual-layer door (outer stainless steel, inner tempered glass) minimizes thermal bridging and condensation risk, enabling uninterrupted visual monitoring of light- or heat-sensitive specimens without compromising chamber stability. Designed for GxP-aligned workflows, the HCP108 meets essential safety and electromagnetic compatibility requirements per IEC 61010-1 and carries full CE marking for use in EU-regulated laboratories.

Key Features

• Six-sided stainless steel heating elements with integrated aluminum thermal mass layer for rapid equilibration and superior temperature homogeneity
• Dynamic humidity control system using distilled water feed and precision vapor generation—no internal humidifier tank or standing water reservoir
• Laminar, turbulence-free air circulation with HEPA-grade pre-filtered intake air, minimizing particle contamination and thermal stratification
• Dual-door construction: outer corrosion-resistant stainless steel shell and inner low-emissivity tempered glass panel for optical access and thermal isolation
• Full AISI 304 stainless steel interior and exterior surfaces—non-porous, autoclavable-compatible, and resistant to aggressive solvents and cleaning agents
• STERICard-enabled validation: all internal components—including sensors, fans, and ventilation ducts—certified for dry-heat sterilization at 160 °C for 4 hours
• Intelligent safety logic: audible alerts for overtemperature, undertemperature, and door-open events; non-volatile memory retains program settings during power interruption
• Modular controller platform with P-type microprocessor-based regulation, supporting both manual operation and automated multi-step profiles

Sample Compatibility & Compliance

The HCP108 accommodates a broad spectrum of sample types requiring defined climatic stress exposure—including pharmaceutical stability testing (ICH Q1A–Q1E), polymer aging studies, electronic component reliability qualification (e.g., JEDEC JESD22-A110), and cell culture preconditioning prior to bioreactor inoculation. Its absence of internal plastic components, seamless welds, and electropolished interior surfaces support ISO 14644-1 Class 5 cleanroom-compatible operation when coupled with appropriate air filtration upgrades. The chamber complies with EN 60335-1 (household and similar electrical appliances), IEC 61010-1 (safety requirements for electrical equipment for measurement, control, and laboratory use), and relevant harmonized standards under the EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. While not intrinsically compliant with FDA 21 CFR Part 11 out-of-the-box, audit-ready data integrity is achievable through optional Celsius software integration with electronic signature and change-tracking functionality.

Software & Data Management

Operation and documentation are supported via three interoperable interfaces: the front-panel touch-enabled P-controller (with real-time graphing and alarm history), the Windows-based Celsius software (v5.0+), and the STERICard-based logging system. Celsius enables remote monitoring, multi-chamber synchronization, protocol scheduling, and export of time-stamped CSV or PDF reports—including temperature/RH deviation plots, calibration logs, and cycle summaries. All data entries are timestamped and user-attributed; optional audit trail activation meets GLP/GMP traceability expectations. The embedded memory retains up to 100 programs and 30 days of 1-minute-interval data even during mains failure. For regulated environments, optional Ethernet or RS485 connectivity supports integration into centralized LIMS or MES platforms via Modbus TCP or ASCII protocols.

Applications

• Pharmaceutical stability testing per ICH guidelines (long-term, accelerated, intermediate conditions)
• Material aging and degradation analysis of polymers, composites, and adhesives under combined thermal/hygrometric stress
• Reliability screening of PCBs, semiconductors, and optoelectronic assemblies (e.g., THB, HAST simulation)
• Pre-conditioning of biological reagents, lyophilized powders, and diagnostic assay kits prior to functional validation
• Environmental simulation for automotive ECU validation (ISO 16750-4, SAE J2347)
• Seed germination and plant tissue culture under precisely defined hygrothermal regimes
• Calibration and verification of hygrometers, psychrometers, and reference humidity generators

FAQ

What is the minimum ambient temperature required for reliable operation of the HCP108?
The unit requires an ambient environment between 15–30 °C and ≤70 % RH (non-condensing) for optimal performance; operation below 15 °C may extend humidity recovery times and affect control stability.
Can the HCP108 be used for sterile storage applications?
No—it is not a sterile storage cabinet. However, its STERICard-compatible design allows full chamber sterilization via dry heat (160 °C / 4 h), making it suitable for depyrogenation of reusable labware and sensor calibration artifacts.
Is distilled water mandatory for the humidity system?
Yes. Only USP/EP-grade distilled or deionized water with conductivity <5 µS/cm is permitted; tap or softened water will cause mineral buildup, pump failure, and inaccurate RH delivery.
Does the HCP108 support external data logging via analog outputs?
Yes—optional 0–10 V or 4–20 mA analog outputs are available for temperature and RH signals, configurable via Celsius software for third-party SCADA or building management systems.
How often does the peristaltic pump tubing require replacement?
Under standard usage (8 h/day, 20–80 % RH cycling), the silicone tubing should be replaced every 12 months or after 2,000 operating hours—whichever occurs first—to ensure volumetric accuracy and prevent microbial ingress.
