Jiayuan MINIB-100I Heated Metal Block Incubator with Thermally Controlled Lid

Overview

The Jiayuan MINIB-100I Heated Metal Block Incubator with Thermally Controlled Lid is a compact, microprocessor-controlled dry-block thermal system engineered for precise and reproducible sample incubation in molecular biology, clinical diagnostics, and routine laboratory workflows. Unlike water baths or conventional heating blocks, this device employs solid aluminum alloy heating blocks with high thermal conductivity and low thermal inertia, enabling rapid temperature stabilization and minimal spatial gradient across the working surface. The integrated thermally regulated lid—functioning as an active heat barrier—minimizes evaporation from open-tube formats (e.g., PCR tubes, microcentrifuge vials), thereby preserving sample integrity during extended incubations. Designed for portability and operational flexibility, the unit operates on 24 V DC input, making it compatible with vehicle power systems, uninterruptible power supplies (UPS), and field-deployable lab setups. Its lightweight construction (≤1 kg) and footprint of less than 180 × 120 × 110 mm support benchtop, mobile cart, or biosafety cabinet integration without compromising stability or thermal performance.

Key Features

• Microprocessor-based PID temperature control with real-time display of setpoint and actual block temperature (0.1°C resolution)
• Thermally controlled lid maintaining surface temperature within ±2°C of block setpoint—critical for preventing condensation and sample loss in low-volume reactions
• Automatic calibration offset adjustment function to compensate for long-term sensor drift or ambient thermal influence
• Integrated self-diagnostic system with audible alarm and on-screen error code upon overtemperature, sensor failure, or power anomaly
• Passive cooling assisted by a low-noise axial fan—reducing cooldown time by up to 40% compared to natural convection alone
• Modular block design supporting rapid interchange of standardized aluminum inserts (MINI-A to MINI-G) for seamless transition between tube formats without tooling
• UL/CE-compliant electrical architecture with dual-stage overtemperature protection (hardware cutoff + software limit)

Sample Compatibility & Compliance

The MINIB-100I accommodates a broad range of common laboratory consumables via interchangeable modules: 0.2 mL PCR strips (MINI-A), 0.5 mL microtubes (MINI-B), 1.5 mL and 2.0 mL centrifuge tubes (MINI-C/D), cuvettes (MINI-E), and larger vessels up to 50 mL (MINI-G). All modules are manufactured from anodized aluminum for chemical resistance, ease of decontamination (autoclavable up to 121°C for non-electronic components), and minimal metal ion leaching. The system meets IEC 61010-1:2010 safety requirements for laboratory electrical equipment and complies with RoHS 2011/65/EU directives. While not certified for ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, its programmable timer, stable thermal profile, and audit-ready temperature logging (via optional RS232/USB interface) support GLP-aligned documentation practices in QC/QA environments.

Software & Data Management

The MINIB-100I operates autonomously via front-panel controls; however, optional firmware upgrades enable serial communication (RS232 or USB-to-serial) for external data capture using third-party LabVIEW, Python (PySerial), or Excel-based acquisition tools. Timestamped temperature logs—including setpoint, measured block temperature, elapsed time, and alarm events—can be exported for traceability in regulated workflows. Firmware supports user-defined ramp-hold profiles (single-step only) and retains settings after power cycling. No proprietary cloud platform or vendor-specific software is required—ensuring full data sovereignty and compatibility with existing LIMS or ELN infrastructures.

Applications

• Enzyme reaction incubation (e.g., restriction digests, ligations, phosphatase treatments)
• Cell culture sample warming prior to transfection or passaging
• Serum inactivation and complement depletion protocols
• Antibody labeling and conjugation reactions requiring precise thermal control
• Standby heating for HPLC autosampler trays or mass spectrometry sample introduction stages
• Field-deployable nucleic acid amplification preparation in point-of-care or veterinary diagnostic settings

FAQ

Can the MINIB-100I be used for PCR setup without a dedicated thermal cycler?
No—it is not a thermal cycler. It provides static or single-step incubation only and lacks programmed denaturation–annealing–extension cycling capability.
Is the heated lid independently controllable?
No—the lid temperature is dynamically coupled to the block setpoint and maintains a fixed offset (typically +2°C) to prevent condensation.
Are replacement modules available for non-standard tube sizes?
Yes—custom module fabrication (MINI-H) is supported per OEM specifications, subject to minimum order quantity and lead time.
Does the unit support continuous operation beyond 999 minutes?
No—the maximum timer duration is 999 minutes; for extended incubations, manual reset or external relay control is required.
What maintenance is recommended for long-term accuracy?
Annual verification using a NIST-traceable calibrated thermometer probe is advised; no internal recalibration tools are user-accessible.
