Rocking shakers

Rocking shakers for gentle mixing of samples

Rocking shakers are indispensable devices for gently mixing solutions, which effectively prevents them from foaming. This is a key aspect in medical diagnostics and working with delicate substances, where the subtle undulating motion protects the structure of samples much better than violent Cortex devices.

By choosing equipment from recognized brands such as IKA or DLAB, you get a guarantee of repeatability of results in each test cycle. Modern models offer a number of functionalities that make everyday work easier:

• an angle of inclination usually 7 degrees,
• infinitely variable speed adjustment up to 100 revolutions per minute,
• varied lifting capacity of up to 10 kg,
• precise digital control with LCD screen,
• Rugged analogue designs with high durability,
• Safe non-slip mats to protect dishes from falling.

The stability of the device is essential when staining gels and conducting cell cultures, which require a steady pace of work. The use of multi-level platforms allows for a significant increase in efficiency, allowing for the simultaneous processing of a larger number of samples with the highest precision and reliability of the analyzes.

Rocker, wavy and 3D motion

Choosing the right dynamics of the device is crucial for the accuracy of test results. While classic rocker shakers perform vertical pendulum movements, modern solutions offer a much wider range of functionality, essential when working with sensitive proteins or delicate biological material.

Today's laboratories use a variety of mixing methods to ensure optimal reaction conditions:

• classic cradle movements for standard applications,
• subtle wavy variants protecting the structure of proteins,
• advanced 3D technology combining rotation with platform inclination,
• precise polar mode to increase process efficiency,
• dynamic roll mode available on the Phoenix RS-RS 5 series.

The use of 3D technology guarantees intensive circulation in three planes, providing a more efficient alternative to standard linear movement. The final success depends on the correct adjustment of the type of movement to the specifics of the liquid and the geometry of the vessel in which the experiment is carried out. Advanced systems allow for full control over these parameters, which translates into repeatability and high quality of the results obtained.

Speed control, tilt angle and load

In laboratory work, precision is the foundation of the success of any experiment. Although rocker devices run softer than vortex mixers, they offer a wide speed range to suit specific requirements. The DLAB SK-R model operates at up to 30 rpm, the Phoenix RS-RR offers 70 rpm, and the fastest CAT ST5 reaches as much as 100 rpm. This range of parameters allows you to perfectly match the mixing dynamics to the density and viscosity of a particular substance.

Modern control systems and well-thought-out design of shakers guarantee users the following benefits:

• smooth movement of the platform effectively preventing foaming of liquids,
• digital control systems that ensure the stability of parameters,
• full repeatability of results in test series,
• stable operation under load in the heavy duty variant,
• protection of delicate protein structures from damage.

Use in cell cultures and gel staining

In modern biotechnology, gentle oxygenation of media is crucial, which protects sensitive cells from mechanical damage. Laboratory shakers effectively improve hybridization and extraction processes, and models equipped with an incubation function guarantee a stable temperature, which is essential for reproducible test results.

Modern devices offer a number of functionalities:

• effective and gentle oxygenation of media,
• protection of cells from mechanical damage,
• precise temperature control in incubators,
• space savings thanks to multi-level platforms,
• Stabilization of dishes by non-slip mats.

Users can choose between digital systems with high-precision LCD screens or extremely durable analogue versions. Both solutions are characterized by quiet operation and high reliability allowing for intensive use in continuous mode.

Multi-level platforms and anti-slip mat

The use of multi-level platforms is a proven way to significantly accelerate laboratory processes. Thanks to them, it is possible to mix samples simultaneously on several levels, which directly translates into higher work efficiency.

The system is designed to ensure maximum safety and precision of operation:

• simultaneous mixing of samples on several floors,
• full stability in intensive three-dimensional movement,
• effective immobilization of vessels thanks to classic mats,
• vibration damping and shock absorption of glass by mats with protrusions,
• possibility of mounting scarves, microplates and flasks,
• Safe operation with loads up to 10 kg.

With dedicated adapters, the system becomes even more flexible, allowing even unusual components such as centrifuge tubes to be mounted. Even under maximum load, the devices maintain impeccable performance, ensuring that valuable research materials are not damaged. It is an ideal solution for modern facilities that focus on high efficiency and full control over the mixing process.

Digital and analogue rocking shakers

The choice of the right laboratory shaker depends primarily on the specifics of the research being conducted. Analogue  models attract with their simplicity – classic knobs guarantee high reliability, which makes them a proven solution in everyday, routine practice.

The digital variants, on the other hand, focus on maximum precision and modernity. They offer a range of amenities, such as:

• easy-to-read LCD screens for ongoing motion monitoring,
• integrated timer for precise work planning,
• advanced speed stabilization systems,
• RS-232 connector for direct data transfer,
• modern mechanisms ensuring full repeatability of results.

Both types of equipment are characterized by exceptional robustness, withstanding even the most intensive use. Choosing a specific model allows you to adjust the tools to the standards of reliable diagnostics and the individual needs of the user.
