What is the Benchtop Orbital Shaker?
A benchtop orbital shaker is a compact unit with a small platform for routine mixing and culture at moderate loads. It is the standard choice for individual workstations and small-volume culture and mixing tasks.
What is the Benchtop Orbital Shaker?
A benchtop orbital shaker is a compact unit with a small platform for routine mixing and culture at moderate loads. It is the standard choice for individual workstations and small-volume culture and mixing tasks.
Overview
The benchtop orbital shaker fits a platform of 250 to 400 mm into a unit that sits on the bench, with speeds of 20 to 300 rpm and orbits of 10 to 25 mm. It holds flasks, tubes or small trays with clamps or racks, and load ratings run 2 to 8 kg. A brushless motor with belt or direct drive and a digital controller with timer is typical, and closed-loop speed control holds rpm under load. Power is modest, usually 30 to 100 W. Construction is a coated steel or aluminum base with a stainless platform. It suits general mixing, staining, small culture batches and teaching, and it pairs well with a separate incubator when temperature control is needed.
How does it work?
An orbital shaker turns an eccentric bearing with a motor, converting rotation into a circular motion of the platform. The offset between the motor axis and the platform center sets the orbit diameter, usually 10 to 50 mm, and the speed is set by the controller. A brushless motor drives through a belt or directly, and sealed bearings support the load so the unit can run for long periods. Closed-loop speed control measures rpm with a tachometer or Hall sensor and corrects against load changes. Platforms bolt to the drive and accept flask clamps, tube racks, trays or bottle holders. A timer or programmable controller runs the cycle, and some models add a soft start, which brings the platform up to speed gradually to avoid spilling liquid from flasks.

What are the technical specifications?
A typical benchtop orbital shaker configuration offers platform size of 250×250 to 400×400 mm, speed range of 20–300 rpm, orbit diameter of 10–25 mm, load rating of 2–8 kg, speed accuracy of ±1 rpm and timer range of 1 min to 99 h. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.
Which applications is it used for?
The Benchtop Orbital Shaker is used in routine sample mixing, gel staining and destaining, small culture batches and teaching laboratory work. Across the wider Orbital Shakers class, laboratories also deploy it for bacterial and yeast culture, liquid-liquid extraction and staining and destaining of gels.
Which standards and certifications apply?
Relevant standards and methods include IEC 61010-1, IEC 61010-2-051 and ISO 9001. Certification candidates for this model are CE, ISO 9001 manufacturing and RoHS; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.
Balance the platform by loading symmetrically, since an uneven load causes vibration, noise and rapid bearing wear, and can move the unit across the bench. Stay within the load rating at the chosen speed and start with a soft or low-speed ramp when flasks are filled. Site the shaker on a level, stable surface with clearance for ventilation and moving parts, and never operate it with the platform unsecured. Clean spills promptly, because media and reagents corrode clamps and platforms. Inspect belts, bearings and clamps on schedule, and check feet and fasteners for loosening that would worsen vibration.
How do I select the right Benchtop Orbital Shaker?
Select the benchtop orbital shaker for small platforms and moderate loads on a single workstation. Heavy-duty or large-platform models suit bigger batches. In the RFQ, specify platform size, speed and orbit, load, clamp types, timer and power supply.
How does it compare with other Orbital Shakers variants?
Choose an orbital shaker for smooth, gentle mixing that suits culture and extraction, and pick the orbit diameter for the application: 10 to 19 mm for gentle work, 19 to 25 mm for most culture and mixing, and 25 to 50 mm for large volumes needing strong agitation. Match the load rating to the heaviest flask set at the working speed, since ratings fall as speed rises. Decide the platform size and clamp types, then the drive and control features, such as closed-loop speed, soft start, timer and duty cycle. For continuous operation, specify a unit rated for it. Confirm power, footprint and whether stacking or a larger platform is needed.

Frequently asked questions about Benchtop Orbital Shaker
Typically 2 to 8 kg when balanced, with the rating falling as speed rises. Exceeding it causes vibration, noise and bearing wear, so the flask set should be weighed or counted against the rating at the working speed.
Only if the shaker is rated for the incubator's temperature and humidity, since motors and electronics have limits. Many laboratories instead use a dedicated shaking incubator when temperature control is required, which avoids condensation and heat problems.
Most use 30 to 100 W on a standard 220 V single-phase circuit, so power is rarely a constraint. Higher speeds and larger platforms draw more, but the load itself has more effect on performance than the motor power.
It mixes, aerates and keeps samples suspended by moving a platform in a circle. Typical uses are microbial and cell culture, liquid extraction, gel staining, sample homogenization and dissolution studies in flasks, tubes and bottles.
Use 10 to 19 mm for gentle mixing and sensitive samples, 19 to 25 mm for most culture, extraction and staining, and 25 to 50 mm for large volumes that need strong agitation. Larger orbits give more movement but can splash or foam light liquids.
Vibration from an unbalanced load, worn bearings or a surface that is not level makes the unit move. Distribute the load symmetrically, tighten clamps, check the feet and fasteners, and keep the speed within the rating to reduce movement.
