Chengmeng CM10 Dry Bath Incubator

Overview

The Chengmeng CM10 Dry Bath Incubator is a compact, microprocessor-controlled thermal platform engineered for precise and stable temperature regulation of samples in sealed tubes, vials, and microplates. Unlike water baths, it employs solid-state aluminum heating and Peltier-based active cooling elements to deliver rapid, uniform thermal transfer without evaporation, contamination risk, or maintenance associated with liquid media. Its operational principle relies on direct conductive heat exchange between the heated/cooled aluminum block and sample containers—ensuring high reproducibility in applications requiring strict thermal consistency, such as enzyme reactions, DNA denaturation/annealing, cell culture pre-warming, and reagent equilibration. Designed for benchtop integration in QC laboratories, clinical diagnostics workflows, and academic research settings, the CM10 operates across a broad range from –10 °C to 100 °C, supporting both ambient-subzero and high-temperature protocols within a single instrument.

Key Features

• Wide dual-mode temperature control: –10 °C to 100 °C, enabled by integrated Peltier thermoelectric modules and high-efficiency resistive heating elements.
• High-precision digital PID control with real-time feedback ensures ≤ ±0.3 °C temperature accuracy and ≤ ±0.3 °C intra-block uniformity across all wells.
• Programmable multi-step protocols: Supports up to 5 independent temperature setpoints with user-defined dwell times; repeatable cycling up to 99 iterations for automated thermal profiling.
• Intelligent power management: Auto-start function resumes last-used program upon power restoration; built-in power-failure recovery retains configuration and elapsed time data.
• Optimized thermal dynamics: Achieves 25 °C to 100 °C ramp in ≤12 minutes; cools from 100 °C to 25 °C in ≤10 minutes and reaches 30 °C below ambient in ≤25 minutes.
• Universal compatibility: Interchangeable aluminum blocks accommodate common formats including 0.2 mL, 0.5 mL, 1.5 mL, and 2.0 mL microcentrifuge tubes, 96-well PCR plates, and 0.2 mL strip tubes.

Sample Compatibility & Compliance

The CM10 accommodates standard laboratory consumables via removable, anodized aluminum heating blocks—designed for mechanical durability, chemical resistance, and minimal thermal lag. All block configurations maintain ISO/IEC 17025-aligned thermal performance under routine use conditions. While not certified for medical device use per IEC 61010-1, the unit complies with general laboratory equipment safety standards (EN 61010-1:2010, UL 61010-1), including overtemperature cutoff, short-circuit protection, and reinforced insulation. Its closed-loop control architecture supports GLP-compliant documentation when paired with external logging systems; however, native audit trail or 21 CFR Part 11 compliance requires integration with validated third-party data acquisition software.

Software & Data Management

The CM10 operates via an intuitive front-panel interface with LED display showing real-time temperature, setpoint, remaining time, and status indicators. It does not feature onboard data logging or USB/Ethernet connectivity. For traceable recordkeeping, users may connect external calibrated thermistors or PT100 probes to standalone dataloggers (e.g., Omega OM-DAQPRO-5300) synchronized with timer events. The device supports manual protocol export via screen capture for inclusion in SOPs and validation reports. Firmware updates are not field-upgradable; all calibration parameters are factory-set and verified against NIST-traceable references prior to shipment.

Applications

• Molecular biology: PCR tube pre-heating, restriction enzyme incubation, ligase reaction setup, and cDNA synthesis thermal equilibration.
• Clinical chemistry: Standard curve preparation at defined temperatures, calibrator stabilization, and immunoassay reagent conditioning.
• Pharmaceutical QA/QC: Dissolution media pre-conditioning, viscosity test sample tempering (per USP ), and stability study intermediate storage.
• Industrial microbiology: Culture media warming prior to inoculation, antibiotic susceptibility testing plate conditioning, and lyophilized reagent reconstitution.
• Education labs: Demonstrating Arrhenius kinetics, enzyme activity vs. temperature profiles, and phase transition behavior in biochemical systems.

FAQ

Does the CM10 support remote monitoring or network connectivity?
No—the CM10 is a standalone instrument with no Ethernet, Wi-Fi, or Bluetooth interfaces. Remote oversight requires external temperature sensors and compatible SCADA or LabVIEW-based acquisition systems.
Is calibration certificate included with purchase?
A factory calibration report (traceable to national standards) is provided with each unit. Full ISO/IEC 17025-accredited calibration must be performed by an accredited third-party lab using documented procedures.
Can the CM10 maintain sub-zero temperatures continuously?
Yes—it sustains temperatures down to –10 °C indefinitely under typical ambient conditions (18–25 °C), though prolonged operation below 0 °C may reduce Peltier module service life if ambient humidity exceeds 60% RH.
What safety protections are built into the system?
Overtemperature shutdown (>105 °C), fuse-protected power input (3 A, 250 V), automatic heater disable during lid opening (if equipped with optional interlock switch), and thermal runaway detection via dual-sensor redundancy.
Are custom block geometries available?
Standard blocks cover common tube and plate formats. Custom-machined blocks can be ordered directly from Chengmeng Technology upon submission of dimensional specifications and minimum order quantities (MOQ: 5 units).
