Drick DRK652 Electrically Heated Constant-Temperature Incubator

Overview

The Drick DRK652 Electrically Heated Constant-Temperature Incubator is a precision-engineered laboratory instrument designed for stable, uniform thermal environments essential in microbiological culture, fermentation process development, and controlled-temperature experimental protocols. Based on air-jacketed dual-sided heating architecture and PID-controlled microprocessor regulation, the DRK652 maintains tight thermal stability across its operational range (ambient +5°C to 65°C), with demonstrated uniformity of ±0.5°C and accuracy of ±0.3°C at the critical 37°C setpoint—standard for bacterial growth studies. Its 152-liter stainless steel (SUS304) chamber supports reproducible incubation conditions under routine QC, academic research, and regulated production environments. The unit complies with GB/T 23914.2–2009 for incubator performance and incorporates design elements aligned with ISO 13485 quality system expectations for medical device-related biological testing.

Key Features

• Air-jacketed dual-sided heating system ensures rapid temperature recovery (<15 min after 3-minute door opening at 37°C) and minimizes internal gradient formation.
• PID microprocessor controller with high-resolution digital display (0.1°C resolution) enables precise setpoint definition and real-time monitoring of chamber temperature.
• Triple-layer insulated double-glazed door with silicone gasket provides enhanced thermal retention and visual observation without compromising stability.
• Three adjustable, load-rated stainless steel shelves (each supporting up to 15 kg) allow flexible configuration for Petri dishes, flasks, test tubes, or multi-well plates.
• Dual independent thermal protection: primary PID control loop plus a mechanical safety thermostat prevents uncontrolled overheating under fault conditions.
• Door-open alarm with audible and visual indicators activates upon prolonged opening (>30 s), supporting GLP-compliant procedural adherence.

Sample Compatibility & Compliance

The DRK652 accommodates standard microbiological containers including 90-mm Petri dishes (up to 80 per shelf), 250-mL Erlenmeyer flasks, 15- and 50-mL conical tubes, and 96-well microplates. Its stainless steel interior resists corrosion from repeated disinfectant exposure (e.g., 70% ethanol, 1% sodium hypochlorite), and seamless welds prevent microbial harborage. The incubator is validated for use in environments requiring documented thermal consistency—supporting internal calibration verification per ISO/IEC 17025 and alignment with USP environmental control guidelines for non-sterile pharmaceutical testing. While not certified for ISO 5 cleanroom integration, it meets ambient lab-grade particulate and airflow specifications per ISO 14644-1 Class 8 when installed in controlled spaces.

Software & Data Management

The DRK652 operates as a standalone analog-digital hybrid system with no embedded data logging or network interface. However, its analog output (0–5 V DC proportional to chamber temperature) enables connection to external chart recorders, SCADA systems, or third-party data acquisition hardware (e.g., NI CompactDAQ, Keysight DAQ970A). Users may integrate the unit into LabVantage or STARLIMS via optional RS-485 Modbus RTU communication module (sold separately), supporting audit-trail-capable temperature trending and electronic batch record linkage where required by FDA 21 CFR Part 11–governed workflows. Calibration certificates traceable to NIM (National Institute of Metrology, China) are provided with each unit.

Applications

• Bacterial and fungal cultivation (e.g., Escherichia coli, Staphylococcus aureus, Candida albicans) under standardized CLSI M07-A10 incubation conditions.
• Enzyme activity assays requiring strict thermal control between 25°C and 60°C.
• Cell line maintenance for non-CO₂-dependent adherent or suspension cultures during pre-incubation phases.
• Accelerated stability testing of raw materials and finished products per ICH Q1A(R2) guidelines (e.g., 40°C/75% RH long-term condition support).
• Quality control of industrial fermentation inocula in food, dairy, and probiotic manufacturing facilities.

FAQ

Is the DRK652 suitable for CO₂-dependent cell culture?
No—the DRK652 does not provide CO₂ concentration control or humidification; it is strictly a dry-air, temperature-only incubator.
What is the recommended calibration frequency?
Annual calibration is advised per ISO/IEC 17025; users should perform in-house verification before critical experiments using NIST-traceable thermistors or PT100 probes.
Can the unit be installed in a cold room?
Yes—operational ambient range is 10–30°C; however, startup time increases below 15°C ambient, and condensation risk requires proper acclimatization prior to power-on.
Does Drick provide IQ/OQ documentation templates?
Yes—validated installation and operational qualification protocols compliant with ASTM E2500-13 are available upon request for regulated laboratories.
Is the stainless steel chamber electropolished?
No—it features mechanically polished SUS304 finish, sufficient for routine decontamination but not equivalent to electropolished surfaces used in aseptic processing equipment.
