DLAB MS-H280 Series LCD Digital Programmable Heating Mantle with Integrated Magnetic Stirrer

Overview

The DLAB MS-H280 Series is a dual-function, microprocessor-controlled heating mantle system engineered for precise thermal management and magnetic stirring in routine laboratory workflows. Unlike conventional single-purpose mantles or stirrers, the MS-H280 integrates a thermally optimized aluminum heating mantle with a brushless DC magnetic stirrer into one compact, safety-certified platform. Its operational principle relies on resistive heating through an embedded alloy coil, coupled with permanent-magnet rotation driven by a sealed, spark-free motor—enabling simultaneous temperature control and agitation without mechanical coupling or external drive units. Designed for compatibility with standard borosilicate glassware, it supports reproducible reaction setup across synthesis, dissolution testing, sample preparation, and quality control protocols under ambient to elevated temperature conditions (up to 380 °C surface temperature). The system adheres to fundamental electrical safety requirements per IEC 61010-1 and incorporates fail-safe architecture aligned with GLP-compliant lab infrastructure.

Key Features

• Modular glassware compatibility: Accepts round-bottom flasks (100–1000 mL) and flat-bottom beakers (100–1000 mL) via interchangeable, heat-resistant fiberglass inner sleeves and high-purity alumina-silica insulation layers.
• Dual independent operation mode: Enables standalone heating (mantle only), standalone stirring (stirrer only), or synchronized heating + stirring—configurable via front-panel LCD interface without hardware reconfiguration.
• Aluminum alloy mantle housing with corrosion-resistant powder-coated finish ensures long-term structural integrity in humid or mildly acidic lab environments.
• Self-calibrating digital temperature control: User-accessible calibration offset function improves thermal accuracy post-installation; typical repeatability ±1.5 °C over 25–300 °C range.
• Integrated thermal safety architecture: Dual redundant safety circuits continuously monitor mantle surface temperature and internal sensor integrity; automatic cut-off triggers upon sensor failure, thermal runaway (>390 °C), or short-circuit detection.
• Residual heat warning system: Persistent “HOT” indicator flashes on LCD display when mantle surface exceeds 50 °C—even after power-off—to prevent accidental contact burns during cooldown phase.
• Brushless DC motor: Sealed, maintenance-free design eliminates carbon brush wear, arcing, and electromagnetic interference; rated for >20,000 hours MTBF at nominal load.

Sample Compatibility & Compliance

The MS-H280 accommodates common laboratory glassware conforming to ISO 3585 (borosilicate 3.3) and ASTM E438 Type I Class A specifications. Its uniform radial heating profile minimizes thermal gradients across vessel bases, supporting consistent kinetics in applications such as reflux, extraction, and buffer equilibration. The unit complies with CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU) and low-voltage safety (LVD Directive 2014/35/EU). While not certified for hazardous area use (ATEX/IECEx), its non-sparking motor and grounded metal enclosure meet general-purpose lab safety expectations under ISO/IEC 17025-accredited facilities. No regulatory certification for FDA 21 CFR Part 11 is applicable, as the device lacks electronic record storage or user audit trail functionality.

Software & Data Management

The MS-H280 operates via an embedded 4-button LCD interface with real-time display of setpoint temperature, actual surface temperature, and stirring speed (0–1200 rpm). It does not feature USB, Bluetooth, or Ethernet connectivity; all parameter adjustments and status monitoring are performed locally. Temperature and speed values are retained in volatile memory during operation but are not logged or exportable. For laboratories requiring traceable thermal profiles, integration with external data loggers (e.g., Omega OM-DAQPRO or Testo 176 T4) is supported via analog 0–5 V output (optional accessory port, sold separately). No proprietary software suite is provided.

Applications

• Controlled-temperature synthesis: Facilitates Grignard reactions, esterifications, and polymerizations requiring stable thermal input and homogeneous mixing.
• Dissolution testing support: Used in preliminary validation of USP Apparatus II setups where bath temperature stability directly impacts release rate interpretation.
• Standard solution preparation: Ensures complete solute dispersion and thermal equilibration prior to pH, conductivity, or titration analysis.
• QC sample conditioning: Heats and homogenizes viscous samples (e.g., emulsions, suspensions) before filtration or instrumental analysis (HPLC, GC).
• Educational labs: Serves as a robust platform for teaching thermodynamics, reaction kinetics, and safe equipment handling principles.

FAQ

Can the MS-H280 be used with plastic or quartz vessels?
No—it is designed exclusively for borosilicate glassware. Plastic containers may deform or emit volatile compounds at elevated temperatures; quartz vessels require higher thermal mass compensation not supported by the default PID algorithm.
Is the temperature sensor replaceable by the end user?
The integrated PT100-class sensor is factory-calibrated and not field-replaceable. If drift exceeds specification, the unit must be returned to DLAB authorized service centers for recalibration or component-level repair.
Does the device support ramp-and-soak temperature programming?
No—only single-point temperature setpoints are supported. Multi-step thermal profiles require external programmable controllers or manual intervention.
What is the maximum recommended continuous operating time?
Rated for uninterrupted operation up to 72 hours under load at ≤300 °C setpoint and ≤800 rpm stirring speed, assuming adequate ventilation and ambient temperature ≤30 °C.
Is there a warranty or service agreement available internationally?
DLAB provides a 24-month limited warranty covering material and workmanship defects. International service support is coordinated through regional distributors; spare parts availability varies by country and requires validated purchase documentation.
