Fisons Whirlimixer Vortex Mixer

• Mixing small liquid volumes in test tubes and vials for chemical and biological assays.
• Resuspending cell pellets and biological samples in microbiology and cell culture.
• Vortexing reagents and buffers in pharmaceutical research and development.
• Preparing samples for analytical techniques such as chromatography and spectroscopy.
• General laboratory mixing tasks requiring rapid and consistent agitation.

Typical vessel capacity

Units of this type commonly accommodate tubes up to 25mm in diameter.

Mixing action

Vortex mixing, creating a swirling action within the vessel.

Speed control

Variable speed control is a common feature, allowing for gentle to vigorous mixing.

Operation modes

Typically offers both continuous and touch-start (press-activated) operation.

Power supply

For the UK market, these units commonly operate on a 230V, 50Hz electrical supply.

Footprint

Compact benchtop design, typically with a small square or rectangular base.

Shakers and incubation mixers are valued for reliable sample preparation and culture growth across biotech and pharmaceutical settings. When buying used models, buyers prioritise consistent temperature control, speed accuracy, and platform stability. Industry sentiment favours machines from established manufacturers with robust build quality. Key strengths include straightforward operation, minimal maintenance requirements, and long operational lifespans. Buyers typically assess motor condition, calibration history, and overall structural integrity before purchase. These instruments remain dependable workhorses in laboratory environments when properly maintained.
