IKA Vortex 1 Compact Orbital Tube Shaker

Overview

The IKA Vortex 1 is a compact, benchtop orbital tube shaker engineered for precise, reproducible vortex mixing of small-volume liquid samples in life science and clinical laboratories. Utilizing a robust eccentric drive mechanism, it generates consistent circular motion with a fixed 4.5 mm orbit diameter—optimized for efficient homogenization without splashing or foaming in standard microcentrifuge tubes (e.g., 0.2–2.0 mL Eppendorf®), PCR tubes, and small-diameter test tubes up to 30 mm. Its design adheres to fundamental principles of orbital agitation, where centrifugal force couples with fluid inertia to induce rapid radial mixing—ideal for resuspension of pellets, reagent dissolution, and pre-PCR sample homogenization. Unlike vortexers with variable orbit geometry, the Vortex 1 maintains mechanical stability across its full speed range (1000–2800 rpm), ensuring repeatable shear profiles critical for assay consistency.

Key Features

• True continuous-speed control from 1000 to 2800 rpm—no stepped settings—enabling fine-tuned optimization for sensitive biological samples.
• Dedicated momentary “touch” mode (point activation) for rapid, hands-free initiation of mixing without speed adjustment—essential for time-critical workflows such as enzyme reactions or cell lysis steps.
• Chemically resistant polymer housing and tube platform, combined with a coated zinc-alloy base, provide long-term durability against common laboratory solvents (e.g., ethanol, isopropanol, dilute acids/bases) and mechanical wear.
• IP40-rated enclosure ensures protection against solid objects ≥1 mm and limited ingress of dust—suitable for standard ISO Class 7 (10,000) clean benches and non-sterile biosafety cabinets.
• Universal 100–240 V AC input with 50/60 Hz compatibility enables seamless deployment across global laboratory infrastructures without voltage converters.
• 100% duty-cycle rated motor with thermal overload protection supports uninterrupted operation during extended protocols, including overnight incubation-assisted mixing.

Sample Compatibility & Compliance

The Vortex 1 accommodates cylindrical containers with outer diameters ≤30 mm, including 0.2 mL PCR strips, 1.5 mL and 2.0 mL microcentrifuge tubes, and standard 13 mm test tubes. Its low-mass oscillating platform minimizes vibration transmission to adjacent instruments—a key consideration in dense bench layouts. The device complies with DIN EN 60529 (IP40), IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use), and meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU). While not certified for use in explosion-proof environments or under GMP Annex 1 sterile conditions, its construction and performance align with GLP documentation standards for routine QC/QA sample preparation.

Software & Data Management

As a stand-alone analog instrument, the Vortex 1 does not incorporate digital connectivity, embedded software, or data logging capabilities. Speed selection is performed via a calibrated rotary dial; no display or electronic feedback is provided. This minimalist architecture eliminates firmware validation burdens and ensures deterministic behavior—critical for regulated environments where audit trails must reflect only user-initiated actions (e.g., manual speed setting and point activation). Laboratories implementing 21 CFR Part 11 compliance may document operational parameters via handwritten logbooks or integrated LIMS entries referencing batch-specific mixing protocols.

Applications

• Resuspension of lyophilized reagents and bacterial pellets prior to downstream analysis.
• Homogenization of viscous solutions (e.g., glycerol stocks, agarose gels, protein lysates) without introducing air bubbles.
• Pre-incubation mixing in ELISA, Western blotting, and nucleic acid extraction workflows.
• Standardization of sample turbidity in microbiological assays (e.g., McFarland standard preparation).
• Supporting temperature-controlled protocols when placed inside refrigerated or ambient-temperature incubators (operational range: 5–40 °C).

FAQ

Does the Vortex 1 support programmable timing or speed ramping?
No. It operates exclusively in manual mode with continuous speed control and momentary activation—no timer, memory function, or acceleration/deceleration profiles are implemented.
Can it be used inside a CO₂ incubator?
No. While rated for ambient temperatures down to 5 °C, the unit is not designed for humidified, elevated-CO₂, or pressurized environments. Condensation risk and material compatibility limitations preclude safe use inside CO₂ incubators.
Is the platform autoclavable?
No. The polymer platform and coated metal base are not autoclave-compatible. Surface decontamination is recommended using 70% ethanol or 0.5% sodium hypochlorite solution, followed by dry wiping.
What is the maximum tube fill volume for optimal vortexing at 2800 rpm?
For stable operation and minimal splashing, fill volumes should not exceed 75% of tube capacity—e.g., ≤1.1 mL in a 1.5 mL tube—to maintain consistent vortex formation and avoid cap leakage.
Does IKA provide calibration certificates or traceable metrology documentation?
The Vortex 1 is classified as a general-purpose laboratory shaker and does not ship with factory calibration certificates. Users requiring documented speed verification may employ an external optical tachometer compliant with ISO/IEC 17025-accredited metrology practices.
