Memmert IPP55plus Low Temperature Incubator with Dual Display

Overview

The Memmert IPP55plus Low Temperature Incubator is an engineered solution for precise, energy-efficient temperature control in life science laboratories. Utilizing solid-state Peltier thermoelectric technology, the IPP55plus implements bidirectional thermal regulation—capable of both heating and active cooling—without mechanical compressors or refrigerants. This principle relies on the Peltier effect: electrical current applied across semiconductor junctions induces directional heat transfer, enabling accurate temperature setpoints from 0 °C to 70 °C with exceptional stability (±0.1 °C typical at 37 °C, per Memmert technical documentation). Unlike conventional vapor-compression systems, the Peltier architecture eliminates oil-lubricated moving parts, resulting in near-zero operational vibration and acoustic emissions (<38 dB(A) at 1 m). Its sealed thermal management design prevents internal condensation—a common source of microbial contamination and sample degradation—by relocating moisture formation exclusively to external heat-sink surfaces. The dual-display interface provides simultaneous readout of setpoint and actual chamber temperature, supporting real-time process verification under GLP-compliant workflows.

Key Features

• Peltier-based thermoelectric heating/cooling system with zero ozone-depleting refrigerants and no compressor-driven mechanical wear
• Energy consumption reduced by up to 90% compared to equivalent compressor-based incubators, verified per DIN EN 60068-3-5 test protocols
• Ultra-low vibration (<0.5 µm peak-to-peak displacement) and silent operation—validated for sensitive applications including insect rearing, cell monolayer culture, and microplate-based assays
• Forced-air convection with tangential fan and optimized baffle geometry ensures uniform temperature distribution (±0.3 °C across working volume, per ISO 15270:2018)
• Dual high-resolution LCD displays: left screen shows setpoint temperature; right screen shows real-time chamber temperature and status indicators
• Stainless steel interior (AISI 304), seamless welded corners, and rounded edges facilitate decontamination and comply with ISO 14644-1 Class 5 cleanroom-compatible cleaning protocols

Sample Compatibility & Compliance

The IPP55plus accommodates standard laboratory vessels—including Petri dishes, multiwell plates (6–384-well), flasks (up to 2 L), and insect rearing cages—within its 53 L usable chamber volume. Its absence of internal condensation supports long-term storage of hygroscopic biological samples, enzymatic reagents, and humidity-sensitive calibration standards. The unit conforms to IEC 61010-1:2010 for laboratory equipment safety and carries CE marking under the EU Machinery Directive 2006/42/EC. It supports audit-ready documentation per FDA 21 CFR Part 11 when integrated with Memmert’s optional data logging software (e.g., memmertLINK), providing electronic signatures, user access levels, and immutable event logs for GxP environments.

Software & Data Management

While the IPP55plus operates as a standalone instrument, it is compatible with Memmert’s memmertLINK PC software via RS232 or USB interface. This platform enables remote parameter configuration, continuous temperature logging (with timestamp, user ID, and alarm flags), and export of CSV/Excel-formatted reports traceable to NIST-traceable reference standards. All data records include digital signatures and tamper-evident audit trails compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate). Optional Ethernet connectivity allows integration into centralized lab infrastructure monitoring systems adhering to IEEE 1394 or BACnet MS/TP protocols.

Applications

• Low-temperature microbiological cultivation (e.g., psychrotrophic bacteria, lactic acid starters at 4–15 °C)
• Controlled-temperature insect colony maintenance (Drosophila, Tribolium) requiring vibration-free environments
• Enzyme kinetics studies where thermal hysteresis or compressor-induced fluctuations compromise reproducibility
• Stability testing of biopharmaceutical intermediates per ICH Q1A(R2) guidelines at sub-ambient conditions
• Pre-incubation of PCR master mixes and cold-adapted restriction enzymes prior to thermal cycling
• Environmental simulation for plant tissue culture and seed germination assays under defined chilling stress

FAQ

Does the IPP55plus require external water supply or drainage for humidity control?
No—the IPP55plus is a dry-temperature-only incubator. Humidity control is not integrated; for combined temperature/humidity applications, Memmert recommends the HPPeco series.
What is the maximum ambient temperature for reliable operation?
The unit is rated for continuous use at ambient temperatures up to 30 °C, per DIN 12880-1 environmental class specifications.
Can the dual display be customized to show additional parameters (e.g., elapsed time, alarm status)?
No—the dual-display layout is fixed to temperature setpoint and measured chamber temperature only; advanced parameter visualization requires memmertLINK software.
Is the Peltier module field-replaceable without factory service intervention?
Yes—Memmert supplies modular Peltier assemblies with standardized mounting interfaces and diagnostic firmware support for qualified service personnel.
How does the IPP55plus meet ISO/IEC 17025 requirements for temperature validation?
It supports 3rd-party sensor mapping per ISO/IEC 17025:2017 Annex A.3 using calibrated PT100 probes; Memmert provides IQ/OQ documentation templates aligned with ASTM E2875-13.
