MEMMERT IPP300 Low-Temperature Biochemical Incubator

Overview

The MEMMERT IPP300 Low-Temperature Biochemical Incubator is an engineered precision environment chamber designed for stable, reproducible temperature-controlled cultivation of biological samples under non-sterile or low-risk microbiological conditions. Operating within a validated range of 10 °C to 37 °C, the IPP300 employs active thermoelectric heating and cooling combined with high-resolution dual 4-wire PT100 resistance temperature detectors (RTDs) for real-time, spatially averaged temperature monitoring and feedback control. Its microprocessor-based fuzzy logic controller ensures minimal overshoot and rapid stabilization—critical for sensitive biochemical assays, enzyme kinetics studies, and long-term cell culture maintenance where thermal drift must remain below ±0.3 °C (typical at setpoint). The unit conforms to DIN EN 61000-6-3 (EMC) and IEC 61010-1 (safety), and its construction meets ISO 13485-aligned manufacturing practices for laboratory equipment used in regulated research environments.

Key Features

• Stainless steel inner chamber (39 L volume) and outer housing—corrosion-resistant, cleanable, and compliant with GLP cleaning protocols
• Dual independent overtemperature protection system: Class 1 (TB) primary safety cutoff and Class 3.1 (TWW) active fuzzy-control override—both certified per DIN EN 60519-1 and IEC 61010-1
• Programmable multi-segment operation: up to 40 time–temperature segments per program, with durations from 1 minute to 999 hours; supports nested loops and SP waiting modes
• Integrated digital clock enabling 24-hour light-cycle simulation—compatible with circadian rhythm studies and photobiological applications
• Configurable fan control: adjustable speed and on/off timing to optimize convective uniformity without inducing desiccation or shear stress on cultures
• Front-panel programming interface with stainless steel glass touchscreen—no external PC required for routine operation
• Onboard data logging: 1024 KB non-volatile memory stores temperature history at user-defined intervals; expandable via optional 32 MB memory card

Sample Compatibility & Compliance

The IPP300 accommodates standard petri dishes, multiwell plates, Erlenmeyer flasks (up to 1 L), and test tubes on its single removable stainless steel shelf. Its interior geometry (480 × 320 × 250 mm) permits unobstructed airflow distribution, verified by thermal mapping per ASTM E2297-21 guidelines. The double-door design—comprising an inner tempered glass door and outer stainless steel door—minimizes heat loss and condensation while maintaining visual sample access. Calibration certificates traceable to DKD (German Calibration Service) are supplied for 10 °C and 37 °C, supporting IQ/OQ documentation for labs operating under ISO/IEC 17025, FDA 21 CFR Part 11 (when paired with MEMMERT’s validated software), and EU GMP Annex 11 requirements.

Software & Data Management

Via RS232 or RS485 serial interface, the IPP300 integrates with MEMMERT’s optional incubator management software for remote parameter configuration, real-time monitoring, and export of timestamped temperature logs in CSV or PDF format. Audit trail functionality—including user login, parameter changes, alarm events, and calibration actions—is enabled when operated in compliance mode. The parallel printer port allows direct hardcopy output of current status or logged intervals without host dependency. All firmware updates are delivered through MEMMERT’s secure engineering portal and undergo version-controlled validation per IEC 62304 Class B software lifecycle standards.

Applications

• Low-temperature enzymatic reaction profiling (e.g., restriction digests, ligations, RT-PCR prep)
• Microbial growth curve analysis under sub-mesophilic conditions (e.g., Listeria, Yersinia)
• Seed germination and plant tissue culture requiring diurnal temperature cycling
• Stability testing of biologics and excipients per ICH Q5C guidelines
• Quality control incubation for pharmaceutical raw materials (USP , EP 2.6.27)
• Environmental simulation for ecotoxicology and aquatic microbiology studies

FAQ

What temperature accuracy and uniformity specifications apply to the IPP300?
At 37 °C, typical temperature uniformity across the chamber is ±0.5 °C (measured at 9 points per DIN 12880), with stability of ±0.2 °C over 24 h. Accuracy is ±0.3 °C when referenced to DKD-traceable calibration.
Is the IPP300 suitable for CO₂-dependent cell culture?
No—the IPP300 is a temperature-only incubator without gas control or humidity regulation. For CO₂ applications, MEMMERT’s IC series or dedicated CO₂ incubators are recommended.
Can the IPP300 be integrated into a LIMS or central lab monitoring system?
Yes—via RS485 Modbus RTU protocol, it supports read-only access to real-time temperature, setpoint, alarm status, and program state for integration with third-party SCADA or LIMS platforms.
Does the unit comply with electromagnetic compatibility (EMC) requirements for shared lab environments?
Yes—it meets EN 61326-1:2013 for laboratory use and has been tested for immunity against radiated RF fields (80 MHz–2.7 GHz) and electrostatic discharge (±8 kV contact).
How is validation support provided for regulated laboratories?
MEMMERT supplies IQ/OQ templates, calibration certificate packages, and firmware version documentation aligned with ASTM E2500-13 and EU GMP Annex 15 principles. Full 21 CFR Part 11 compliance requires use of validated software and controlled electronic signatures.
