MENTS MS-100 Heated Vortex Mixer with Temperature Control

Overview

The MENTS MS-100 Heated Vortex Mixer is a precision-engineered laboratory shaker designed for simultaneous temperature-controlled incubation and orbital mixing. It operates on the principle of controlled horizontal orbital oscillation combined with PID-regulated resistive heating, enabling reproducible thermal and mechanical stimulation of biological samples. Unlike conventional water baths or standalone vortexers, the MS-100 integrates both functions within a single compact platform—eliminating workflow interruptions caused by sample transfer between instruments. Its architecture supports applications requiring strict thermal homogeneity (≤±0.3 °C) and consistent rotational dynamics across microcentrifuge tubes, PCR plates, and enzymatic assay vessels. The device is engineered for routine use in molecular biology labs, quality control environments, and academic research settings where protocol standardization, traceability, and equipment footprint are critical constraints.

Key Features

• DC brushless motor drive ensures low-noise operation (20,000 hr MTBF), and zero maintenance requirements;
• PID-based intelligent temperature control with auto-tuning capability delivers rapid thermal response (≤12 min from 25 °C to 100 °C) and high stability (≤±0.3 °C uniformity across the platform);
• Independent functional modules: users may activate/deactivate heating, shaking, and timing functions separately—enabling flexible configuration for protocols such as heat activation, enzyme denaturation, or ambient-speed mixing;
• Interchangeable aluminum heating blocks (A–J options) accommodate diverse vessel formats including 96-well PCR plates, 0.2–50 mL centrifuge tubes, and flat-bottom microtiter plates;
• Backlit LCD interface displays real-time temperature, speed, and remaining time; supports calibration offset adjustment per module type;
• Programmable endpoint alert (audible beep) and optional auto-restart after power interruption ensure protocol continuity in unattended operation;
• Short-pulse vortex mode (press-and-hold) allows manual agitation without altering preset parameters;
• Compact footprint (260 × 195 × 150 mm) and lightweight design (7.0 kg) facilitate integration into biosafety cabinets or modular lab benches.

Sample Compatibility & Compliance

The MS-100 accommodates standardized consumables used across life science workflows—including ISO-certified PCR tubes, ASTM D4294-compliant sample vials, and USP endotoxin assay containers. Its temperature and speed profiles comply with common method validation requirements for nucleic acid extraction, protein solubilization, and immunoassay preparation. While not certified for GLP/GMP production environments, the instrument supports audit-ready documentation when paired with external logging systems. All heating blocks undergo thermal mapping verification per IEC 61000-4-3 electromagnetic compatibility standards. No refrigeration module is included; operation is limited to heating-only configurations.

Software & Data Management

The MS-100 operates via embedded firmware without external software dependency. All operational parameters—including setpoints, runtime, and calibration offsets—are stored in non-volatile memory. Though it lacks USB/Bluetooth connectivity or cloud synchronization, its timer and alarm system meet basic FDA 21 CFR Part 11 readiness criteria for electronic record integrity when used in conjunction with lab notebook documentation. Optional module-specific calibration routines allow users to apply individual correction factors per block type (e.g., A for 96×0.2 mL, G for 24×5 mL), improving inter-batch consistency during multi-vessel experiments.

Applications

• Thermal activation of restriction enzymes and ligases prior to DNA assembly;
• Homogenization of viscous lysates in RNA isolation protocols;
• Equilibration of antibody-conjugated beads in ELISA plate coating steps;
• Pre-incubation of cell culture media components before sterile filtration;
• Accelerated dissolution testing of lyophilized reagents under controlled agitation;
• Standardized mixing of calibration standards for HPLC and mass spectrometry workflows.

FAQ

Does the MS-100 support cooling functionality?

No—the MS-100 is a heated-only shaker. Cooling requires external cold blocks or integration with a separate refrigerated incubator.
What is the maximum safe operating temperature for plastic PCR plates?

When using Block F (96-well flat-bottom plate), sustained operation above 95 °C is not recommended for polycarbonate or polypropylene plates due to potential warping; validated performance is confirmed up to 90 °C.
Can multiple modules be heated simultaneously?

Only one module can be installed and operated at a time. Module swapping is tool-free and takes less than 30 seconds.
Is the timer resolution adjustable below 1 minute?

Time input is discrete in 1-minute increments; however, the short-pulse vortex mode provides sub-second manual agitation control.
How is temperature uniformity verified across the platform?

Each unit undergoes factory thermal mapping using NIST-traceable PT100 probes at nine spatial points; test reports are available upon request.
