Orbital Shaker

<h2>What are orbital shakers?</h2>
&nbsp;
Orbital shakers are laboratory mixing platforms that move their platform surface in a horizontal circular (orbital) motion at controlled speed, agitating the contents of vessels clamped or placed on the platform by inertial forces as the platform traces a circular path. The circular orbit creates a mixing pattern in flask liquids that promotes oxygen transfer from the headspace into the culture broth, which is the rate-limiting step for aerobic bacterial and yeast cultures grown in shaking flasks. Orbital shaker speed, orbit diameter, and fill volume together determine the mixing intensity and oxygen transfer rate in a culture.

<h2>How to choose an orbital shaker</h2>
&nbsp;
Choose an incubated orbital shaker for bacterial, yeast, or mammalian culture
Incubated orbital shakers maintain above-ambient temperature inside an integrated chamber, allowing cultures to grow at their optimum temperature while being agitated. This format is commonly used for microbial culture, protein expression, fermentation screening, and other temperature-controlled applications.
Choose a refrigerated shaker for cold-temperature incubation or hybridization
Refrigerated orbital shakers maintain temperatures below ambient, typically from approximately 4&deg;C to room temperature, making them suitable for enzyme reactions, nucleic acid hybridization, and other temperature-sensitive workflows requiring agitation.
Match orbit diameter to your flask size and culture volume
Orbital shakers are available with different orbit diameters, commonly 1 cm, 2 cm, 3 cm, and 5 cm. Smaller orbits are generally used for smaller flasks and lower volumes, while larger orbits provide increased liquid movement and aeration for larger flasks and higher culture volumes.
Select a speed range appropriate for your application
Different applications require different shaking speeds. Microbial culture often operates at higher speeds to support oxygen transfer, while hybridization, staining, and washing procedures typically require gentler agitation. Selecting a shaker with a broad speed range increases flexibility across applications.
Confirm platform size and maximum load capacity
Platform dimensions determine how many flasks, bottles, or microplates can be processed simultaneously. Maximum load capacity should accommodate the combined weight of vessels and media to ensure stable operation during continuous shaking.
&nbsp;
<h2>Specifications context</h2>
&nbsp;
The oxygen transfer rate in a shaking flask depends on shaking speed, orbit diameter, flask geometry, and fill volume. Appropriate combinations of these variables improve mixing efficiency and culture performance. Stackable orbital shakers remain a common solution for laboratories that require multiple simultaneous culture conditions while conserving bench and floor space.

Orbital Shaker Accessories

<h2>What are orbital shaker accessories?</h2>
&nbsp;
Orbital shaker accessories are the platform attachments and holders that secure specific vessel types to a shaker platform during operation. Erlenmeyer flasks typically require spring-clip clamps that hold the flask securely while allowing unrestricted liquid movement, microplates use dedicated plate holders, tube rack inserts accommodate centrifuge and microcentrifuge tubes, and non-slip mats provide flexible placement for vessels during lower-speed mixing applications.
&nbsp;
<h2>What you will find:</h2>
&nbsp;
<ul>
<li>
Dedicated Flask Platforms: Pre-configured platforms designed to securely hold specific sizes of Erlenmeyer flasks or standard microplates.
</li>
<li>
Universal Magnetic Platforms: Versatile, metallic base platforms engineered for instant, tool-free swapping of magnetic clamps and tube racks.
</li>
<li>
Magnetic Flask Clamps: Single-size and combo magnetic clamps designed for quick attachment to hold 25ml up to 500ml Erlenmeyer flasks.
</li>
<li>
Magnetic Tube Racks: Specially designed magnetic racks to accommodate culture tubes, microplates, and large conical bottles in various orientations.
</li>
</ul>
&nbsp;
<h2>How to choose orbital shaker accessories</h2>
&nbsp;
Select Erlenmeyer flask clamps by flask volume
Flask clamps are designed for specific flask sizes, including 125 mL, 250 mL, 500 mL, 1 L, and larger culture flasks. Each clamp is engineered to fit the dimensions of a particular flask size, ensuring secure retention during shaking.
Confirm compatibility with your shaker platform
Accessory mounting systems vary between manufacturers and shaker models. Before ordering, verify that the clamp, holder, or rack is listed as compatible with the specific orbital shaker platform being used.
Choose a microplate holder suitable for your application
Microplate holders secure standard microplates during incubation and mixing procedures. Different holder designs support different operating speeds and plate formats, making compatibility and intended use important selection criteria.
Use a non-slip platform mat for flexible vessel placement
Non-slip mats provide a simple solution for holding bottles, flasks, trays, and other containers at low to moderate shaking speeds. They are useful when vessel configurations change frequently and dedicated clamps are not required.
Verify tube rack capacity and platform fit
Tube rack inserts are available for common laboratory tube formats, including microcentrifuge tubes and conical centrifuge tubes. Confirm that the rack dimensions fit within the shaker platform and that the rack accommodates the desired number of samples per run.
&nbsp;
<h2>Specifications context</h2>
&nbsp;
Orbital shaker accessories are designed to keep vessels securely positioned while exposed to continuous circular motion. Flask clamps, plate holders, and tube racks should be selected according to vessel dimensions, operating speed, and platform compatibility. Stainless steel spring-clip clamps remain one of the most widely used accessory formats for laboratory culture applications due to their durability and secure retention.
