DHS MaxMixer-100 Industrial High-Capacity Vortex Mixer

Overview

The DHS MaxMixer-100 is an industrial-grade high-capacity vortex mixer engineered for robust, contamination-free homogenization of large-volume liquid samples in regulated and non-regulated laboratory and production environments. Unlike magnetic stirrers or overhead agitators, the MaxMixer-100 employs eccentric orbital oscillation to induce controlled vortex motion within vessels—generating consistent radial shear forces without introducing external magnetic fields, mechanical shafts, or submerged components. This principle ensures uniform mixing across heterogeneous suspensions, emulsions, cell cultures, reagent batches, and viscous process streams—particularly where sterility, material compatibility, and operator safety are critical. Designed for continuous operation in GMP-compliant manufacturing suites and QC laboratories, the unit features a fully welded 316 stainless steel frame and platform, IP54-rated electrical enclosure, and vibration-damped structural architecture to maintain positional stability under full-load conditions (up to 100 L).

Key Features

• High-capacity mixing: Supports single-vessel operation up to 100 L (e.g., standard IBC totes, stainless steel drums, or custom-lined polypropylene tanks)
• Precision programmable control: Digital interface enables independent setting of mix duration (1–99 min), inter-cycle pause interval (0–99 sec), and total cycle count (1–9), with real-time LED feedback and non-volatile memory retention
• Adjustable oscillation dynamics: Frequency range of 50–100 rpm with fixed 50 mm amplitude—optimized to balance turbulent energy input and mechanical stress on vessel integrity
• GMP-ready construction: All wetted and structural surfaces fabricated from electropolished 316 stainless steel; no painted or coated components; cleanroom-compatible surface finish (Ra ≤ 0.8 µm)
• Operational safety system: Integrated emergency stop button (IEC 60947-5-5 compliant), overload current protection, and automatic thermal cutoff at ≥85 °C motor winding temperature
• Acoustic optimization: Noise emission <62 dB(A) at 1 m distance during continuous 100 rpm operation, achieved via balanced counterweight design and elastomeric mounting isolators

Sample Compatibility & Compliance

The MaxMixer-100 accommodates cylindrical, rectangular, and tapered containers with stable base geometry—including stainless steel drums (30–100 L), UN-certified IBCs, glass carboys (with reinforced bases), and FDA-compliant HDPE/PP process vessels. It is validated for use with aqueous buffers, organic solvents (e.g., ethanol, isopropanol), low-viscosity oils (<500 cP), microbial growth media, and particulate-laden slurries (≤15% w/v solids). The device meets ISO 13849-1 (PL d, Category 3) for functional safety and conforms to electromagnetic compatibility requirements per EN 61326-1:2013. While not certified as Class I, Division 1 hazardous location equipment, it is suitable for general-purpose industrial zones (Zone 2 / Class I, Div. 2) when operated per manufacturer-specified ventilation guidelines.

Software & Data Management

The MaxMixer-100 operates via embedded firmware with no external PC dependency. All user-defined parameters are stored in EEPROM with write-cycle endurance >100,000 cycles. Audit trail functionality logs timestamped events—including power-on/off, parameter changes, emergency stop activation, and thermal fault occurrences—for GLP/GMP traceability. Optional RS-485 Modbus RTU interface (available upon request) supports integration into SCADA systems and centralized MES platforms. When paired with DHS’s optional MaxLog Pro data acquisition module (sold separately), users can export CSV-formatted run logs compliant with FDA 21 CFR Part 11 requirements—including electronic signatures, user authentication, and immutable record archiving.

Applications

• Biopharmaceutical manufacturing: Homogenization of bulk buffer solutions prior to filtration and filling; resuspension of lyophilized intermediates in large-scale bioreactor harvest processing
• Environmental testing labs: Uniform dispersion of sediment samples in EPA Method 1664B-compliant extraction protocols
• Food & beverage QA/QC: Standardized mixing of viscosity-modified sauces, dairy blends, and nutritional fortification premixes
• Chemical synthesis support: Pre-reaction blending of catalyst slurries and multi-phase reagent systems under inert atmosphere (when used with sealed, pressure-rated vessels)
• Academic core facilities: High-throughput sample preparation for metabolomics, proteomics, and environmental DNA extraction workflows requiring scalable, hands-free agitation

FAQ

What is the maximum recommended fill level for a 100 L container on the MaxMixer-100?

For optimal vortex formation and mechanical stability, DHS recommends ≤85% nominal volume (i.e., ≤85 L for a 100 L vessel) with liquids having dynamic viscosities below 1,000 cP.
Can the MaxMixer-100 be used with pressurized or vacuum-sealed vessels?

Yes—provided the vessel is rated for the applied oscillatory load and sealing mechanism remains intact under 50 mm amplitude displacement. DHS advises validation of seal integrity under operational conditions prior to routine use.
Is calibration required, and does DHS provide calibration documentation?

Oscillation frequency and timer accuracy are factory-verified against NIST-traceable standards. A Certificate of Conformance (CoC) is supplied with each unit; optional UKAS-accredited calibration services (including amplitude verification) are available through authorized DHS service centers.
Does the unit support continuous 24/7 operation?

The MaxMixer-100 is rated for S1 continuous duty cycle under ambient temperatures of 15–35 °C and relative humidity ≤80% non-condensing. Thermal management and bearing lubrication are designed for ≥10,000 hours MTBF.
Are replacement platforms or custom fixtures available?

Yes—DHS offers application-specific platform inserts (e.g., drum cradles, IBC clamping kits, and dual-vessel adapters) as well as OEM-integrated mounting brackets for inline production line integration.
