Thermo Scientific Heratherm IMP180 Biochemical Incubator

Overview

The Thermo Scientific Heratherm IMP180 Biochemical Incubator is a precision-engineered, Peltier-based temperature-controlled chamber designed for stable, low-noise, and frost-free operation across a wide thermal range of +5 °C to +70 °C. Unlike conventional compressor-driven incubators, the IMP180 leverages solid-state thermoelectric (Peltier) technology to deliver bidirectional temperature control—enabling both active cooling below ambient and precise heating—without refrigerants, mechanical compressors, or defrost cycles. This architecture eliminates vibration transmission and acoustic noise, making it especially suitable for sensitive biological samples including microbial cultures, enzyme assays, biochemical stability studies, and cell-based quality control workflows. Engineered in Germany and compliant with IEC 61010-1 safety standards, the IMP180 integrates forced-air convection via an internal fan system to ensure ±0.3 °C temperature uniformity (at 37 °C, measured per ISO 1533:2022 Annex B), supporting reproducible experimental outcomes under GLP- and GMP-aligned laboratory practices.

Key Features

• Peltier-based thermoelectric control: Enables accurate, maintenance-free cooling and heating without condensation, compressor wear, or manual defrosting.
• Forced-air convection system: Ensures high spatial temperature homogeneity (< ±0.4 °C at 25 °C, typical) and rapid thermal recovery after door opening.
• Intuitive programmable controller: Supports time-dependent temperature profiles with weekly/daily scheduling, real-time setpoint adjustment, and user-defined calibration offset.
• Dual-glass viewing door with external heating element: Prevents interior fogging and enables non-intrusive sample monitoring during operation.
• Integrated safety architecture: Includes adjustable over-temperature alarm, independent sensor monitoring, and automatic cut-off on critical fault detection.
• Modular connectivity: Standard RS232 serial interface for external data logging; optional analog output and Ethernet-ready expansion modules available for integration into centralized lab monitoring systems.
• Flexible footprint options: Desktop configuration (IMP180) and floor-standing variant (IMP280) with lockable casters for reconfigurable lab layouts.

Sample Compatibility & Compliance

The IMP180 accommodates standard microbiological vessels—including Petri dishes, test tubes, flasks, and multiwell plates—within its 180 L usable chamber volume. Its stainless-steel interior, rounded corners, and smooth surfaces support routine decontamination using ethanol, hydrogen peroxide vapor (HPV), or validated liquid sporicides. The unit complies with key international regulatory frameworks relevant to life science instrumentation: IEC 61010-1 (electrical safety), EN 61326-1 (EMC), and meets essential requirements for use in environments governed by ISO/IEC 17025, FDA 21 CFR Part 11 (when paired with validated third-party data acquisition software), and EU Annex 11 (computerized system validation). IQ/OQ documentation packages are available upon request to support installation and operational qualification in regulated laboratories.

Software & Data Management

While the IMP180 operates autonomously via its embedded microcontroller, its RS232 port enables direct connection to PCs or industrial PLCs for passive temperature logging. Users may deploy generic terminal emulators (e.g., PuTTY, Tera Term) or integrate with LIMS-compatible SCADA platforms using Modbus RTU protocol (via optional firmware upgrade). For audit-trail compliance, Thermo Fisher recommends pairing the IMP180 with validated third-party environmental monitoring software that supports electronic signatures, user access controls, and automated report generation aligned with ALCOA+ principles. Raw temperature data is output at configurable intervals (1–600 seconds), timestamped and formatted as ASCII CSV streams.

Applications

The IMP180 serves as a core platform in multiple regulated and research-intensive domains: microbial enumeration and shelf-life testing in food & beverage QA/QC; biochemical assay development and stability assessment in pharmaceutical R&D; water quality analysis (e.g., heterotrophic plate count, coliform incubation per ISO 6222 and EPA Method 1604); low-temperature cell culture adaptation and cryopreservation recovery protocols; and enzymatic reaction kinetics studies requiring tight thermal control below ambient. Its extended lower limit (+5 °C) also supports psychrophilic organism cultivation and cold-chain validation studies.

FAQ

Does the IMP180 require regular defrosting?

No—Peltier-based operation eliminates frost accumulation; no manual or automatic defrost cycles are needed.

Can the IMP180 maintain temperature uniformity with frequent door openings?

Yes—the forced-air system achieves ≤3 min recovery to ±0.5 °C after a 30-second door opening (per ISO 1533 test protocol).

Is IQ/OQ documentation included with purchase?

IQ/OQ templates and execution support services are available as optional add-ons; they are not shipped standard but can be ordered pre-installation.

What is the maximum ambient operating temperature for the IMP180?

The unit is rated for continuous operation in rooms maintained at ≤30 °C and ≤70% RH (non-condensing).

Can external sensors be connected for independent verification?

Yes—two dedicated 6 mm diameter cable ports allow insertion of calibrated PT100 or NTC probes for parallel monitoring and validation.
