Esco CelCulture® CCL-170-B-8-P Direct-Heating CO₂ Incubator with Integrated Refrigeration System

Overview

The Esco CelCulture® CCL-170-B-8-P is a direct-heating, refrigerated CO₂ incubator engineered for precision-controlled cell culture environments where thermal stability across sub-ambient and elevated temperatures is critical. Unlike conventional incubators relying solely on resistive heating, this model integrates a closed-loop refrigeration module—enabling stable operation from 12°C below ambient up to 60°C. This extended thermal range supports demanding applications in stem cell expansion, primary mammalian cell culture, marine and amphibian cell isolation, insect cell line maintenance, and regenerative medicine workflows where physiological relevance requires precise hypothermic or normothermic conditions. The chamber employs a microprocessor-controlled PID algorithm to coordinate heating elements and refrigerant cycling, minimizing temperature overshoot and ensuring uniformity (< ±0.3°C at 37°C, typical). Chamber construction utilizes seamless stainless steel (AISI 304) with double-wall insulation and an inner door seal to reduce thermal load fluctuations during access.

Key Features

• Integrated refrigeration system enabling stable operation from 12°C below ambient to 60°C—critical for cold-adapted cell lines and metabolic studies.
• 90°C validated moist-heat sterilization cycle compliant with UK Health Protection Agency (HPA) standards; fully traceable validation protocol included.
• ULPA-grade air filtration (≥99.999% @ 0.12 µm) combined with ISOCIDE® antimicrobial coating on all interior surfaces and a 0.2 µm CO₂ gas inlet filter to prevent microbial ingress.
• Direct-heating architecture eliminates water-jacket thermal lag, improving response time and reducing condensation risk in high-humidity protocols.
• Gas-tight chamber design with dual-door configuration (optional 4-panel sealed inner glass door, COA-1006/F) minimizes CO₂ loss and humidity drift during frequent access.
• Modular gas control architecture supporting CO₂-only, CO₂/O₂ dual-gas, or full tri-gas (CO₂/O₂/RH) monitoring and regulation via field-installable electronic analyzers (COA-2010-F through COA-2017-F).

Sample Compatibility & Compliance

The CCL-170-B-8-P accommodates standard tissue culture formats—including T-flasks, multiwell plates, roller bottles, and Petri dishes—within its 170 L working volume. Its uniform temperature distribution (±0.2°C at setpoint), CO₂ concentration stability (±0.1% at 5%), and rapid humidity recovery (<15 min from 5% to 95% RH after door opening) meet requirements for sensitive primary cultures and low-passage stem cells. Regulatory compliance includes CE marking per IEC 61010-1 and IEC 61326-1, adherence to ISO 13485 quality management principles for medical device manufacturing support, and compatibility with GLP/GMP documentation workflows via optional IQ/OQ packages (COA-2011-F). The 90°C sterilization cycle satisfies USP sterility assurance requirements for non-sterile ancillary equipment used in aseptic processing environments.

Software & Data Management

• Voyager Smart Remote Monitoring Software (5250001) enables real-time web-based access to chamber parameters—including temperature, CO₂, O₂, RH, door status, alarm logs, and sterilization cycle history—across LAN/WAN networks.
• Analog output interface (COA-1005/F) provides 4–20 mA or 0–10 V signals for integration into centralized building management systems (BMS) or laboratory information management systems (LIMS).
• Optional chart recorders (COA-2012-F to COA-2014-F) deliver continuous analog traceability of temperature and/or humidity for audit-ready hardcopy records aligned with FDA 21 CFR Part 11 requirements when paired with secure user authentication and electronic signature modules.
• All firmware versions support audit trail logging with timestamped operator actions, parameter changes, and alarm events—essential for ISO 17025-accredited testing laboratories and clinical research facilities.

Applications

This incubator serves as a platform for advanced life science research requiring environmental fidelity beyond standard 37°C/5% CO₂ paradigms. Key use cases include: cryopreserved stem cell recovery under controlled ramp-down protocols; marine organism cell culture requiring 15–20°C operation; amphibian and insect cell lines (e.g., Sf9, High Five™) maintained at 27–28°C with precise O₂ modulation; co-culture models requiring independent O₂ gradients; and food microbiology studies involving psychrotrophic pathogen growth kinetics at sub-ambient temperatures. Its robust construction and validated sterilization make it suitable for shared core facilities handling biosafety level 1 (BSL-1) and select BSL-2 workloads under institutional biosafety committee oversight.

FAQ

Does the CCL-170-B-8-P support dual-gas (CO₂/O₂) control?
Yes—via optional COA-2016-F electronic analyzer module, enabling independent regulation of CO₂ (0–20%) and O₂ (1–21%) concentrations with ±0.1% accuracy.

Is the 90°C moist-heat sterilization cycle validated per international standards?
Yes—the cycle is HPA-certified and includes thermocouple mapping data, dwell-time verification, and biological indicator (Geobacillus stearothermophilus) challenge reports provided with COA-2011-F IQ/OQ documentation.

Can humidity be monitored and logged continuously?
Yes—when equipped with COA-2017-F (CO₂/O₂/RH analyzer) and COA-2014-F (temperature/RH chart recorder) or Voyager software, RH is sampled every 10 seconds and archived with metadata for regulatory review.

What electrical specifications does the unit require?
The CCL-170-B-8-P operates on 115/230 VAC, 50/60 Hz, single-phase supply; maximum power draw is 1.8 kW during simultaneous heating and refrigeration at extreme setpoints.

Are replacement ULPA filters and ISOCIDE® coating reapplication services available?
Yes—Esco-certified service technicians provide scheduled filter replacement and surface re-coating using ISO Class 5 cleanroom protocols; filter part number: CCL-ULPA-01.
