Memmert HPP2200eco Environmental Stability Chamber for Pharmaceutical Testing

Overview

The Memmert HPP2200eco is a purpose-engineered environmental stability chamber designed exclusively for long-term pharmaceutical stability testing in accordance with ICH Q1A(R3), Q5C, and regional regulatory expectations (e.g., USP , EU Annex 1). Unlike conventional compressor-based chambers, the HPP2200eco employs solid-state Peltier technology for both heating and cooling—enabling precise, bidirectional thermal control without refrigerants, mechanical compressors, or oil-lubricated components. This architecture eliminates vibration transmission (85 % of long-term stability studies are conducted.

Key Features

• Solid-state Peltier thermoelectric modules—no refrigerants, no compressor maintenance, zero ozone-depleting substances (ODP = 0, GWP = 0)
• Passive air circulation design with laminar flow distribution and integrated fan speed modulation for load-adaptive thermal homogeneity
• Triple-point user calibration function directly accessible via touchscreen interface—supports IQ/OQ/PQ validation without external hardware
• Modular LED illumination option with selectable CCT (2700 K warm white, 6500 K cool white, or dual-channel mixing) and 1–100 % intensity control in 1 % increments
• Corrosion-resistant stainless-steel interior (AISI 304), seamless welded corners, and HEPA-filtered recirculation path compliant with ISO 14644-1 Class 5 requirements
• Real-time data logging with timestamped T/RH values, configurable sampling intervals (1–300 s), and encrypted CSV export via USB port

Sample Compatibility & Compliance

The HPP2200eco accommodates diverse sample formats—including open trays, sealed vials, blister packs, and primary packaging—without compromising environmental integrity. Its chamber geometry and airflow profile have been validated using ASTM E2259-22 (Standard Practice for Performance Verification of Environmental Chambers) and meet the spatial uniformity criteria specified in ICH Q1A for long-term (25 °C/60 % RH) and intermediate (30 °C/65 % RH) storage conditions. All firmware and control logic comply with FDA 21 CFR Part 11 requirements for electronic records and signatures when paired with Memmert’s optional validation package (including audit trail, user role management, and electronic signature workflows). Full documentation support includes Factory Acceptance Test (FAT) reports, Installation Qualification (IQ) templates, and Operational Qualification (OQ) protocols aligned with ISO/IEC 17025 and EU GMP Annex 15.

Software & Data Management

The integrated Memmert eCO Control software provides local touchscreen operation and optional Ethernet/Wi-Fi connectivity for remote monitoring via web browser or dedicated client application. Data integrity safeguards include automatic checksum verification, write-once-read-many (WORM) log archiving, and tamper-evident timestamps traceable to NIST-traceable time servers. Exported datasets include full metadata (chamber ID, operator ID, calibration history, sensor serial numbers) and conform to CDISC SDTM standards for regulatory submission readiness. Optional 21 CFR Part 11 compliance mode enables role-based access control (RBAC), electronic signatures with biometric or token authentication, and immutable audit trails covering all parameter changes, calibration events, and alarm acknowledgments.

Applications

• I CH Q1A-compliant long-term, accelerated, and stress stability studies for APIs, drug products, and biologics
• Photostability testing per ICH Q5C when equipped with calibrated LED illumination module
• Reference standard storage under controlled temperature/humidity per USP
• Excipient compatibility screening and degradation kinetics modeling
• Environmental stress qualification of primary and secondary packaging systems
• GLP-regulated stability programs requiring full traceability, audit readiness, and reproducible environmental profiles

FAQ

Does the HPP2200eco require refrigerant handling or periodic compressor servicing?
No. The solid-state Peltier system contains no refrigerants, oils, or moving mechanical parts subject to wear—eliminating scheduled maintenance and associated downtime.
How is temperature and humidity uniformity verified across the chamber volume?
Uniformity is validated per DIN 12880 using 9–15 calibrated PT100 sensors distributed across three vertical planes; results are documented in the OQ report and available upon request.
Can the LED illumination module be calibrated for photostability testing?
Yes—the optional LED system includes factory calibration certificates traceable to PTB (Physikalisch-Technische Bundesanstalt) for irradiance (W/m²) and spectral distribution (320–400 nm), meeting ICH Q5C requirements.
Is remote monitoring and alarm notification supported?
Yes—via Memmert’s eCO Cloud service (optional subscription), users receive SMS/email alerts for out-of-spec conditions, power failures, or door-open events, with secure TLS 1.3 encrypted data transmission.
What documentation is provided for regulatory submissions?
Standard delivery includes FAT report, IQ/OQ templates, calibration certificates (NIST-traceable), and a Declaration of Conformity to EU Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU.
