Orbital Shaker (Incubated vs. Non-Incubated): Advantages for Bacterial Culture Aeration, Protein Elution, and Even Mixing
In any lab that regularly handles liquid samples, the orbital shaker earns its place as a core instrument. Its circular motion path makes it well suited to a wide range of jobs — growing bacterial cultures, eluting proteins, running staining and destaining steps, hybridisation work, and everyday liquid mixing. Labtron's orbital shaker line reflects this versatility, offering several models with shaking speeds reaching up to 350 rpm and platform footprints sized for different sample loads.
What Sets Orbital Motion Apart
Unlike shakers that rock, tilt, or move in a straight line, an orbital shaker keeps its platform moving in a circular path at a set orbit diameter and speed. The result is even agitation across the entire platform surface, meaning every flask, tube, or microplate on board experiences the same motion regardless of its position. Labtron's range spans shaking speeds from as low as 10 rpm up to 350 rpm across its various models.
This platform-wide consistency is a major differentiator compared with other shaking mechanisms, particularly for labs running several vessels at once and needing comparable results across the board. Labtron's catalogue reflects this with a range of orbit diameters, weight capacities, and platform sizes built around different workflow demands.
Bacterial Culture Aeration
Growing aerobic bacteria successfully depends heavily on oxygen transfer into the medium. The continuous circular motion of an orbital shaker keeps the culture liquid moving, increases its exposure to the headspace above, and helps distribute nutrients while clearing waste products throughout the vessel.
Labtron's orbital shakers are a strong fit for this application, with speed ranges and multi-flask platform options designed for culture work. For labs scaling up, the range also extends to double-decker and triple-decker configurations that support larger batch volumes.
Protein Elution
Elution steps typically call for gentle, uninterrupted agitation so that buffer moves evenly across membranes, gels, or bead-based media. The circular sweep of orbital motion suits this well, delivering steady, even coverage rather than a repeated back-and-forth impact.
Several Labtron models include adjustable speed settings and built-in timers, useful for elution protocols that run over longer periods. Some models add working-temperature control for temperature-sensitive samples, while others are built for use within already-controlled lab environments.
Even Mixing Across Applications
Perhaps the broadest use case for an orbital shaker is simply even mixing — buffer preparation, staining and destaining, wash steps, and other routine liquid-handling tasks where uniformity matters.
Labtron's lineup covers this ground with a variety of platform sizes, shaking modes, and timer ranges, letting users match a shaker to their sample volume and type. Several models are also designed for energy efficiency during extended runs, which matters for long mixing or incubation protocols.
Choosing Between Incubated and Non-Incubated Models
Whether to choose an incubated or non-incubated orbital shaker comes down to whether temperature control needs to be built directly into the shaking unit. Incubated models make sense when a stable temperature is a required part of the protocol; non-incubated models work well when the shaker will operate in an already temperature-controlled or ambient environment.
Labtron's orbital shaker category spans both types, with different operating ranges, speeds, and platform capacities, so the right choice ultimately depends on the specific application and workflow requirements.
The Labtron Range at a Glance
Labtron's orbital shakers run from compact benchtop units to large, high-capacity platforms, along with specialised formats such as 3D orbital shakers and magnetic-drive designs. Across the category, users will find features like ±1 rpm speed accuracy, built-in timers, and load capacities suited to both single-sample and multi-sample processing.
