BIO-DL FeelVotex-3 Vortex Mixer

Overview

The BIO-DL FeelVotex-3 Vortex Mixer is an engineered solution for rapid, reproducible sample homogenization in routine laboratory workflows. It operates on the principle of eccentric circular oscillation—where a motor-driven eccentric shaft induces controlled orbital motion at the platform surface, generating consistent vortex formation within liquid samples contained in tubes. This mechanical design ensures uniform energy transfer across diverse tube geometries without requiring manual intervention or variable speed tuning. Unlike variable-speed vortexers, the FeelVotex-3 maintains a fixed rotational frequency optimized for broad compatibility with standard microcentrifuge tubes (1.5–2.0 mL), PCR strips, Eppendorf-style tubes, and small-volume vials (up to 45 mm diameter). Its low-center-of-gravity architecture—achieved via precision zinc alloy die-cast base construction—minimizes lateral displacement during operation, even under high-load or prolonged mixing conditions. The device meets fundamental ergonomic and functional requirements for GLP-compliant sample preparation environments where repeatability, footprint efficiency, and operational transparency are critical.

Key Features

• Eccentric orbital drive system delivering stable, non-slip vortex generation across all compatible tube formats
• Zinc alloy die-cast base providing structural rigidity, vibration damping, and long-term dimensional stability
• Wear-resistant silicone rubber oscillation pad ensuring consistent amplitude transmission and extended service life (>50,000 cycles under normal use)
• Integrated LED power breath light offering real-time visual status feedback—illuminated during standby, pulsing during active operation
• Compact footprint (125 × 125 × 140 mm) enabling placement on crowded benchtops or inside biosafety cabinets
• Dual-power capability: standard AC adapter input (100–240 V, 50/60 Hz) with optional external battery pack support for field-deployable applications

Sample Compatibility & Compliance

The FeelVotex-3 accommodates tubes with outer diameters up to 45 mm, including conical-bottom centrifuge tubes (15 mL and 50 mL formats when partially filled), standard 1.5 mL microtubes, 0.5 mL PCR tubes, and 0.2 mL strip tubes. Its fixed-frequency oscillation profile has been validated for homogeneous suspension of low-viscosity aqueous solutions, cell suspensions (e.g., mammalian HEK293 or CHO cultures post-thaw), reagent dilutions, and immunoassay plate pre-mixing steps. While not intended for high-viscosity or particulate-laden suspensions requiring shear-intensive dispersion, it complies with general electrical safety standards applicable to Class I laboratory equipment (IEC 61010-1). No regulatory certification (e.g., CE, UL, FDA 510(k)) is claimed; users are advised to verify local conformity requirements prior to integration into regulated workflows.

Software & Data Management

The FeelVotex-3 is a standalone electromechanical instrument with no embedded firmware, network interface, or data logging functionality. As such, it does not generate electronic records, audit trails, or time-stamped operation logs. This design aligns with ISO/IEC 17025:2017 Clause 7.7.1 for equipment used in non-automated testing procedures, where manual usage logs maintained by laboratory personnel satisfy traceability requirements. For laboratories operating under 21 CFR Part 11 or EU Annex 11, the device may be included in equipment qualification protocols (IQ/OQ) as a “non-data-generating auxiliary tool,” with operational verification performed via periodic amplitude and cycle consistency checks using calibrated digital tachometers.

Applications

• Routine resuspension of lyophilized reagents and enzyme stocks prior to assay setup
• Homogenization of DNA/RNA extraction lysates in silica-membrane spin columns
• Pre-incubation mixing of ELISA and lateral flow assay reagents
• Cell pellet resuspension following centrifugation in microbiology and immunology workflows
• Field-based point-of-care sample prep where portability and battery operation are required
• Quality control sampling in pharmaceutical manufacturing environments (non-GMP support role)

FAQ

Is the FeelVotex-3 suitable for mixing viscous samples such as glycerol solutions or agarose gels?
No. Its fixed-frequency eccentric oscillation is optimized for low-to-medium viscosity liquids (<50 mPa·s). Highly viscous or gel-phase materials require shear-intensified mixing methods (e.g., magnetic stirring or rotor-stator homogenizers).
Can the oscillation pad be replaced if worn?
Yes. BIO-DL supplies OEM replacement silicone pads (Part No. FV3-PAD-SR) with standardized M4 threaded mounting for field replacement without tools.
Does the device support timer-based operation?
No. The FeelVotex-3 operates continuously while activated via momentary contact switch; timing must be managed externally using laboratory timers or stopwatch protocols.
What is the expected service life under typical lab usage?
Rated for ≥10,000 hours of cumulative operation based on accelerated life testing of the brushless DC motor and mechanical linkage assembly.
Is the zinc alloy base susceptible to corrosion in humid environments?
The base undergoes electrophoretic coating treatment per ISO 4520, providing resistance to ambient humidity and incidental exposure to common buffer solutions (e.g., PBS, Tris-HCl), though direct immersion is not recommended.
