Overview

The MK2000-2HL Dual-Module Dry Bath Incubator is an engineered thermal platform designed for precise, reproducible, and simultaneous temperature control across two independent sample blocks. Unlike traditional water baths or single-zone metal blocks, this instrument integrates a thermally regulated PCR-style lid—mechanically actuated and actively heated—to minimize condensation, prevent sample evaporation, and ensure stable thermal coupling during extended incubation or thermal cycling protocols. Its core architecture leverages high-conductivity aluminum alloy blocks, precision-machined well geometries, and closed-loop PID fuzzy logic control to deliver laboratory-grade thermal performance without fluid media. The system operates within a validated range of ambient +5°C to 100°C (with 105°C safety limit), making it suitable for enzyme reactions, nucleic acid hybridization, cell lysis, antigen retrieval, and low-cycle PCR applications where consistent block-to-sample heat transfer is critical.

Key Features

• Dual independent heating modules controlled by a single high-stability PID algorithm—ensuring synchronized yet individually calibrated thermal output
• Integrated thermal lid with adjustable pressure and active heating (up to 110°C), eliminating condensation and reducing tube deformation risk during prolonged heating
• Stainless steel anti-explosion cover plates (standard) provide mechanical containment for pressurized tubes and meet ISO 15195:2019 recommendations for safe thermal handling of sealed microtubes
• Capacitive touchscreen interface with real-time graphical temperature/time curve display and intuitive navigation
• 60 programmable protocols, each supporting up to four sequential temperature–time segments; all programs retain settings after power cycle
• Auto-diagnostic system continuously monitors heater resistance, sensor continuity, and lid position—triggering audible/visual alerts upon fault detection
• Modular compatibility with 14 standardized block configurations—including 96-well PCR plates, 384-well formats, slide holders, and solid blocks—for seamless assay scalability
• Optional internal Pt100 sensor or external probe input (via 2-mm jack) enables traceable calibration against NIST-traceable references

Sample Compatibility & Compliance

The MK2000-2HL accommodates standard microcentrifuge tubes (0.2 mL to 5.0 mL), PCR strips, full-format plates (96- and 384-well), microscope slides, and custom-shaped vessels via user-selectable or OEM-customized blocks. All modules conform to ISO 8573-1 purity class 5 for surface finish and dimensional tolerance, ensuring repeatable seating depth and thermal contact area. The instrument meets IEC 61010-1:2010 safety requirements for laboratory electrical equipment and complies with electromagnetic compatibility standards EN 61326-1:2013. While not certified as a medical device, its thermal accuracy and data integrity features—including non-volatile protocol storage and timestamped event logging—support GLP-compliant workflows and audit-ready documentation under FDA 21 CFR Part 11 when paired with validated software.

Software & Data Management

No proprietary PC software is required for basic operation; however, the device supports optional USB-C firmware updates and protocol import/export via FAT32-formatted flash drives. All temperature profiles, runtime logs, and alarm events are stored in internal memory with automatic timestamping (YYYY-MM-DD HH:MM:SS). For integration into LIMS or ELN environments, ASCII-formatted CSV export is available through the serial interface (RS-232, configurable baud rate), enabling automated capture of start/stop times, setpoints, and deviation flags. Audit trail functionality includes operator ID fields (user-definable alphanumeric tags), change history for modified protocols, and write-protected archival of completed runs—facilitating compliance with ISO/IEC 17025 clause 7.7 on result reporting integrity.

Applications

• Enzymatic digestions (e.g., restriction enzyme incubations at 37°C or 50°C)
• Nucleic acid denaturation and annealing steps in endpoint PCR and isothermal amplification
• Antigen unmasking in immunohistochemistry using citrate or EDTA buffer heating
• Protein solubilization and ligand-binding assays requiring precise thermal ramping
• Quality control testing of temperature-sensitive reagents (e.g., polymerases, ligases, reverse transcriptases)
• Cell culture sample warming prior to transfection or passaging
• Controlled drying of thin-film samples on glass slides or silicon wafers

FAQ

Does the MK2000-2HL support gradient temperature operation across the two modules?

No. Both modules share a common thermal control loop and maintain identical setpoints; independent gradient programming is not supported.

Can the thermal lid be disabled for non-PCR applications?

Yes. The lid heating function can be deactivated via menu setting while retaining mechanical closure for convection suppression.

What calibration documentation is provided with the unit?

Each shipment includes a factory calibration certificate referencing NIST-traceable standards at three points (37°C, 65°C, 95°C), valid for 12 months from date of issue.

Is the device compatible with third-party LIMS via network connectivity?

No Ethernet or Wi-Fi interface is built-in; integration requires RS-232-to-TCP/IP gateway hardware or USB-to-serial adapters configured at the host system level.

Are spare modules covered under warranty?

Standard modules carry a 12-month limited warranty; custom-machined blocks are excluded unless specified in writing at time of order.
