StableTemp Low-Temperature Incubator 39063-05

Overview

The StableTemp Low-Temperature Incubator Model 39063-05 is a precision-engineered environmental chamber designed for controlled low-temperature cultivation, storage, and stabilization of biological samples, reagents, and sensitive materials in life science laboratories. Unlike standard ambient or CO₂ incubators, this unit operates across an extended temperature range from −10 °C to +70 °C—enabling applications such as psychrophilic microorganism growth, enzyme stability studies, cold-chain validation, and temperature-dependent assay development. Its thermal architecture employs a high-efficiency refrigeration system coupled with resistive heating and advanced PID control logic to maintain setpoint accuracy within ±0.2 °C across the entire working volume. The chamber utilizes dual-wall construction with polyurethane (PU) foam insulation and a stainless-steel exterior shell to minimize thermal bridging and external heat ingress—critical for long-term stability under variable ambient conditions.

Key Features

• Stainless-steel exterior housing with corrosion-resistant plastic interior liner for chemical compatibility and ease of decontamination
• Digitally controlled LED display interface with real-time temperature readout and visual over/under-temperature alarm indicators
• Independent over-temperature safety cutoff circuit (mechanical backup) compliant with IEC 61000-4-2 and UL 61010-1 requirements
• Integrated 2A power outlet on inner door panel for powering ancillary devices (e.g., small sensors, data loggers, or low-power stirrers)
• Five-tier shelving configuration: two adjustable stainless-steel shelves plus three fixed-position shelves mounted on the door—optimized for vertical space utilization and sample accessibility
• Castor-mounted base with locking swivel wheels for stable positioning and safe relocation within laboratory workflows
• Energy-efficient compressor system with eco-friendly R134a refrigerant and low-noise operation (<52 dB(A) at 1 m)

Sample Compatibility & Compliance

This incubator is validated for use with microbiological cultures (including Pseudomonas, Cryobacterium, and Colwellia spp.), cell-based cryopreserved stocks, nucleic acid preparations, protein standards, and pharmaceutical reference materials requiring non-humidified thermal conditioning. As a dry-air chamber, it does not support humidity-controlled environments—making it unsuitable for mammalian cell culture but ideal for applications where condensation or moisture-induced degradation must be avoided. The device conforms to key regulatory frameworks including ISO 13485:2016 (for medical device-related testing), ASTM E2872–19 (Standard Practice for Environmental Chambers Used in Biological Testing), and supports GLP-compliant documentation through optional external data logging interfaces. It is CE-marked and RoHS-compliant, with electrical safety certification per EN 61010-1:2010.

Software & Data Management

While the 39063-05 operates via standalone digital controls, it includes analog output (0–10 VDC) and RS-232 serial port connectivity for integration into centralized lab monitoring systems (e.g., LabVantage, Thermo Fisher SampleManager, or custom SCADA platforms). Optional third-party software packages support time-stamped temperature logging, alarm event capture, and export to CSV or PDF formats—facilitating audit readiness for FDA 21 CFR Part 11 compliance when paired with appropriate electronic signature and audit trail modules. All firmware updates are delivered via secure USB firmware loader, with version history traceable in internal memory.

Applications

• Growth and maintenance of cold-adapted bacterial and fungal strains
• Long-term storage of temperature-sensitive enzymes, antibodies, and diagnostic reagents
• Thermal stress testing of biologics and excipients during formulation development
• Accelerated stability studies per ICH Q1A(R2) guidelines at sub-ambient conditions
• Calibration verification of thermocouples, RTDs, and portable dataloggers
• Pre-conditioning of test specimens prior to mechanical or rheological characterization

FAQ

Is humidity control available on this model?
No—Model 39063-05 is a dry-air, non-humidified incubator. Humidity regulation is not supported.
Can this unit be used for sterile cell culture?
Not recommended. It lacks HEPA filtration, UV sterilization, and CO₂ control; intended for non-sterile, low-bioburden applications.
What is the maximum allowable ambient operating temperature?
The unit is rated for continuous operation in ambient environments up to 32 °C with ≥15 cm clearance on all sides for ventilation.
Does it include a factory calibration certificate?
Yes—a NIST-traceable calibration report for temperature sensor accuracy (±0.15 °C at 25 °C) is supplied with each unit.
Are replacement shelves and castors available as spare parts?
Yes—genuine OEM accessories (Part Nos. ST-SH-02, ST-CR-04) are stocked and ship globally within 5 business days.
