Mechanical laboratory stirrer

Mechanical agitators for laboratory and industry

Today's laboratories base their efficiency on reliable mechanical agitators, which form the foundation for precise testing processes. DanLab provides technologically advanced solutions dedicated to the chemical, food and cosmetics industries. Thanks to the diverse offer, including both compact and industrial models, it is possible to efficiently process liquids even in large-size tanks.

A key advantage of these systems is their versatility and ability to mix very high viscosity substances. These devices handle volumes of up to 200 liters, which, in combination with the fast-shear variants, results in a perfectly homogeneous solution structure. Such precision directly translates into the reliability and repeatability of each test carried out, significantly raising the standards of work in a modern plant.

The range includes professional equipment from market leaders, ensuring many years of operation in demanding conditions:

• IKA brand solutions,
• Velp devices,
• systems from Heidolph,
• reliable Ohaus equipment,
• CAT brand products.

Mechanical agitators – technical parameters

The choice of a professional stirrer depends primarily on  the viscosity of the substance and the scale of the planned activities. Advanced models can easily handle very dense masses, offering high torque and high drive power, which allows for extremely precise adjustment of process parameters.

Modern mixing systems are distinguished by the following parameters:

• handling of substances with viscosities up to 100,000 mPa·s,
• precision two-stage gearbox,
• intelligent torque compensation system,
• advanced motor overload protection,
• durable IP54 housing,
• innovative microprocessor-controlled rheometric tests.

Thanks to the use of modern electronic systems, CAT  devices guarantee that a constant pace of work is maintained even with changes in the density of the mixture, which ensures the highest precision and repeatability of tests available on the market.

Rods and ends – propeller, vane and anchor

Selecting the right stirrer geometry is the foundation for success in any laboratory process. The drive goes to the vessel through a solid shaft, and the following elements take care of the service life and stability of the entire system:

• precision PTFE guides,
• durable FPM seals,
• high corrosion resistance of steel,
• sterile cleanliness of glass and Teflon,
• protective polymer coatings,
• vibration-damping shaft shock absorbers.

The way the liquid moves depends on the tip you choose. Propeller agitators generate axial flow for low-viscosity substances, and vane variants force radial motion. Anchor agitators work well for dense masses, while turbines are irreplaceable for dispersing components. The solid construction combined with modern materials creates a barrier to acids and aggressive chemicals.

Mechanical and magnetic stirrers in our offer

Our state-of-the-art magnetic stirrers use a precise magnetic field to efficiently combine liquids, which guarantees full control over the process. The SmartChuck  system brings a new quality to everyday laboratory duties. With innovative handles, parts are  replaced quickly and without the use of keys, allowing researchers to focus on their scientific work instead of servicing equipment.

Investing in professional solutions ensures:

• solid tripods that ensure the stability of the entire structure,
• practical paws for stocks and lifts to facilitate the organization of the station,
• specialized flocculators for accurate jar testing,
• obtaining a perfectly homogeneous structure of each tested sample,
• full repeatability of physicochemical characteristics of solutions and emulsions.

Digital control and brushless motor

Modern laboratory mixers combine innovative technology with the highest precision of operation. Thanks to the use of modern components, work becomes more efficient, and research processes gain stability even under dynamically changing loads.

• extremely quiet operation and stability thanks to brushless motors,
• precise control in rotational and vibration mode by fuzzy logic,
• Current preview of parameters on LCD or TFT displays,
• high thermal safety of samples thanks to Pt100 probes,
• the possibility of full automation of work through built-in timers,
