IKA LabDisc Ultra-Thin Magnetic Stirrer

Overview

The IKA LabDisc Ultra-Thin Magnetic Stirrer is an engineered solution for precise, low-profile stirring in constrained laboratory environments—particularly under fume hoods, inside incubators, or within modular automation workstations. Unlike conventional stirrers with mechanical gearboxes or rotating motors, the LabDisc employs a contactless electromagnetic drive system based on high-efficiency planar coil arrays. This solid-state architecture eliminates moving parts, bearings, and brushes—ensuring zero mechanical wear, silent operation, and long-term reliability. The device operates via dynamic polarity reversal: every 30 seconds, the magnetic field orientation shifts to reverse stir bar rotation direction, enhancing homogenization efficiency in viscous or heterogeneous samples without requiring manual intervention. Its ultra-low profile (just 12 mm height) enables seamless integration beneath narrow vessel necks or within stacked benchtop configurations where vertical clearance is limited.

Key Features

• Ultra-thin form factor (12 mm height) optimized for space-constrained applications including glove boxes, environmental chambers, and multi-tiered lab automation setups.
• IP65-rated enclosure ensures full protection against dust ingress and low-pressure water jets—suitable for humid or splash-prone environments such as wet chemistry labs or QC cleanrooms.
• Chemically resistant polyester film-coated aluminum plate surface withstands repeated exposure to common solvents, acids, and bases without degradation or discoloration.
• Non-slip silicone feet provide stable positioning on smooth or inclined surfaces while minimizing vibration transmission during high-speed operation.
• Energy-efficient design: 5 W input power with 3 W effective output delivers consistent torque up to 1500 rpm while maintaining thermal stability across extended duty cycles.
• No internal motor or gears—reliance solely on electromagnetic induction eliminates maintenance requirements and extends service life beyond typical electromechanical stirrers.

Sample Compatibility & Compliance

The LabDisc supports standard PTFE- or glass-coated magnetic stir bars up to 25 mm in length, accommodating vessels from 10 mL vials to 800 mL beakers (tested with aqueous media). Its flat, uniformly heated-compatible plate allows optional integration with external temperature-controlled platforms—though the unit itself does not include heating functionality. All materials comply with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Mechanical safety and ingress protection conform to DIN EN 60529 (IP65), and electrical safety meets IEC 61010-1:2010 for laboratory equipment. While not certified for sterile or GMP-critical processes out-of-the-box, its sealed construction and cleanable surface support alignment with GLP documentation protocols when used in validated workflows.

Software & Data Management

The IKA LabDisc operates as a standalone analog-controlled instrument with no embedded microprocessor, firmware, or digital interface. As such, it does not generate electronic records, lack audit trail capability, and is not compliant with FDA 21 CFR Part 11 requirements. This design choice prioritizes electromagnetic compatibility (EMC), operational simplicity, and immunity to software obsolescence—making it suitable for regulated environments where deterministic behavior and traceable manual operation are preferred over digital dependency. Speed adjustment is performed via a calibrated analog dial with tactile feedback; no calibration certificate is supplied, though users may verify rotational consistency using an external tachometer per ISO 27889:2017 guidelines for stirrer performance verification.

Applications

• Low-volume reagent mixing in analytical sample preparation workflows (e.g., buffer dilution, standard curve preparation).
• Stirring during enzymatic assays or cell culture media equilibration where minimal heat generation and vibration isolation are critical.
• Integration into custom-built fluidic manifolds or microfluidic reactor staging systems requiring compact, EMI-quiet agitation sources.
• Use in teaching laboratories where durability, intuitive operation, and chemical resistance support high-throughput student experiments.
• Supporting ASTM D445 (kinematic viscosity) or ISO 3104 sample homogenization prior to viscometer analysis—provided vessel geometry permits adequate stir bar immersion depth.

FAQ

Does the LabDisc include a heating function?
No. The LabDisc is a non-heating magnetic stirrer. Temperature control must be achieved externally using a heated platform or water bath.
Can it be used with corrosive solvents like concentrated HCl or acetone?
Yes—the polyester film-coated plate surface and sealed electronics housing resist short-term exposure to common organic solvents and dilute mineral acids. Prolonged contact with strong oxidizers (e.g., concentrated nitric acid) is not recommended.
Is speed calibration traceable to national standards?
The device lacks built-in calibration memory or digital output. Users performing metrologically sensitive work should validate speed accuracy periodically using a NIST-traceable optical tachometer.
What is the maximum viscosity this stirrer can handle at 1500 rpm?
Performance depends on stir bar geometry and vessel shape. With a 25 mm bar in a 100 mm beaker, stable agitation is achievable up to ~500 mPa·s (e.g., 1% CMC solution); higher viscosities require reduced speed or alternative agitation methods.
Does IKA provide a warranty or service support outside Germany?
IKA offers a standard 2-year manufacturer’s warranty globally through authorized distributors. Technical support and spare parts distribution follow regional service agreements aligned with ISO/IEC 17025-accredited calibration partners.
