Typical Applications

Unique Features / Advantages

iSwix Jr (Mini, fixed)

Standard cup head for single tubes up to 30 mm diameter (e.g. up to 50 mL centrifuge tubes)​

Analog (fixed speed; no speed knob)

Quick, routine vortexing of individual microtubes or small test tubes in small labs or personal workspaces

Ultra-compact footprint; heavy base with suction feet prevents “walking”​; simple one-touch operation; rugged design for basic mixing tasks

iSwix Jr NXT (Mini, fixed)

Standard cup head; tubes up to 30 mm diameter​

​

(e.g. 1.5 mL to 50 mL tubes)

Analog (fixed speed)

Quick mixing of single tubes (samples, reagents) where a compact, portable mixer is needed

Next-gen mini vortex with improved durability – features a low-voltage power supply and suspension design for longer switch life​

; slightly larger and heavier than original Jr for better stability

iSwix Jr VT NXT (Mini, variable)

Standard cup head; tubes up to 30 mm diameter​

​

Analog (variable speed dial)

Small-scale experiments requiring gentle to vigorous mixing (user can dial down speed for delicate samples)

Combines compact size with variable speed control (2000–4200 RPM) for flexibility​

; same improved design as Jr NXT (suction footing, enhanced switch longevity) for reliable operation

iSwix FS (Full-size, fixed)

Comes with a round platform and rubber cup attachments for single-tube mixing​

(test tubes, vials up to ~30 mm). Not designed for microplate/flask attachments (fixed high speed)

Analog (toggle switch: on/off for continuous, or touch mode)

Routine sample mixing at a consistent high speed – ideal for quick vortexing in teaching labs or standardized protocols that use a single vigorous mixing speed

Robust die-cast body for stability​; no speed adjustment needed (simple operation); no “walking” issues due to inbuilt counter-balance and heavy weight​; IP21 spill-safe design for longevity

iSwix (Full-size, analog)

Interchangeable attachments: standard cup head included for single tubes, plus optional platforms for a microplate, foam inserts for microtubes (24 ×1.5 mL), or a flask up to 250 mL​

. Max tube diameter ~30 mm by default

Analog (variable speed knob)

General-purpose lab mixing – suitable for a wide range of tasks from gentle resuspension to vigorous vortexing of various containers

Versatile mixer with adjustable speed (0–2800 RPM)​

for gentle or vigorous mixing; 3-way switch (touch/standby/continuous) for convenience​; counter-balanced drive ensures stable, quiet operation​; small footprint and optional attachments expand its use (e.g. mix flasks, microplates)​

iSwix VT (Full-size, digital)

Accepts same attachments as iSwix (microtube racks, microplate, flask platform – optional)​

while a standard cup head is typically included

Digital control (LED display with push-button or knob input for speed & time)​

​

Advanced applications requiring precise and repeatable mixing – e.g. enzyme reactions, assays needing timed mixing, or protocols requiring specific speeds and durations

Programmable digital mixer: adjustable speed 300–4200 RPM with ±1 RPM resolution​, built-in timer (1–999 min) and digital display​; Pulse mode (run-pause-run cycling) to enhance mixing efficiency​; maintenance-free BLDC motor for quiet, long-life operation​; can be used in cold rooms or fume hoods​

.

iSwix Jr VT (Mini, older variable)

Standard cup head; tubes up to 30 mm diameter​

Analog (variable speed dial)

Small-scale experiments needing variable agitation – similar use cases as Jr NXT VT, but older model

Compact with variable speed: 2500–4500 RPM range​

for gentle to vigorous mixing; suction-cup feet and die-cast base for stability​; designed for quick mixing in tight spaces with the flexibility of speed control

iSwix MV (Digital Multi-tube)

Includes multiple foam rack attachments for simultaneous mixing of many tubes/flasks: e.g. 72×1.5/2 mL microtubes, 60×7 mL, 45×15 mL, 18×50 mL conical tubes, or 6×250 mL flasks​

(all included). Max load up to ~4.5 kg of samples​

​

Digital (microprocessor control with digital display and buttons)

High-throughput mixing – ideal for labs processing large batches of samples in parallel (e.g. clinical diagnostics, QC labs, extractions requiring vortexing dozens of tubes at once)

High-capacity vortexer: heavy-duty BLDC motor can handle large loads without overheating​; adjustable timer 1–999 min & infinite run​; programmable pulse mode with user-set run/stop intervals (30–99 s) and both clockwise & counter-clockwise motion​

for thorough mixing; extremely stable (≈18 kg unit with non-slip feet) despite vigorous multi-tube operation.
