IKA T 50 digital ULTRA-TURRAX disperser, 0.25 to 30 l, up to 10,000 rpm, 0003787000

The IKA S 50 N - G 45 G dispersing tool represents a high-purity and extremely powerful fluid-mechanical system solution for the professional comminution, homogenisation and suspension of sample media on a laboratory and pilot-plant scale. This precision-manufactured rotor-stator system has been specifically validated for use with the high-performance IKA dispersing drives of the ULTRA-TURRAX T 50 series. In complex processes within the chemical industry, food analysis, cosmetics manufacturing or biotechnology, the rapid disruption and mixing of coarse sample structures is the primary criterion for producing homogeneous suspensions or stable emulsions in a gentle and time-efficient manner for subsequent process or analytical steps. Fluid-mechanical comminution through optimised rotor-stator geometry The process-engineering heart of the unit is the generator in the tried-and-tested G version (Coarse). The perfectly matched geometry of the rotor and stator generates extremely high mechanical impact, cutting and shear forces in the transient shear gap, whilst maintaining a high axial flow rate. This mechanical kinetics is ideally designed to capture, disintegrate and homogenise lumpy samples, agglomerates, powders or viscous liquid-liquid phases in a flash. The open design of the generator head ensures excellent circulation of the medium, which minimises thermal hotspots in the sample vessel in a way that is gentle on the material and ensures process reliability. Material-related inertness and complete sterilisability The materials science design of the dispersing rod is consistently optimised for maximum chemical resilience and absolute freedom from contamination. All functional elements in contact with the medium are made of high-purity, stainless steel grade 1.4404 (AISI 316L). An extremely low-friction and wear-resistant PTFE bearing system is used for the shaft bearing. This combination of materials allows for continuous use in aggressive acids, alkalis and organic solvents. To ensure a sterile sampling environment and to completely prevent cross-contamination in multi-user operations, the entire tool can be easily sterilised in an autoclave or cleaned gently with standard disinfectants. Process reliability and flexible system integration The mechatronic system architecture guarantees safe and vibration-free power transmission even at maximum speeds of up to 10,000 revolutions per minute. The dispersing shaft can be quickly secured in the T 50 digital drive via the standardised connection without the need for tools. Thanks to the generous immersion depth of up to 250 mm and the fluid-mechanical geometry, the tool is certified for a wide working volume ranging from 0.5 to 20 litres (based on water). This offers laboratory managers and industrial users maximum flexibility when scaling up processes from research to pilot plant scale.

The IKA S 50 N - G 45 G - ST dispersing tool represents a high-purity and extremely powerful fluid-mechanical system solution for the professional comminution, homogenisation and suspension of demanding sample media on a laboratory and pilot-plant scale. This precision-manufactured rotor-stator system has been specifically validated for use with the high-performance IKA dispersing drives of the ULTRA-TURRAX T 50 series. In complex processes within the pharmaceutical processing industry, food analysis, biotechnology or pulp research, the disruption of viscous, fibrous or elastic sample structures is the primary criterion for producing homogeneous suspensions in a gentle and time-efficient manner for subsequent analytical steps. Fluid-mechanical comminution via sawtooth geometry The process-engineering heart of the tool is the generator in a special ST (Saw Tooth) design. The distinctive geometry of the saw teeth on the rotor and stator generates extremely high mechanical impact, cutting and shear forces in the transient shear gap. This mechanical kinetics is ideally designed to cut and disintegrate fibrous matrices – such as tissue structures, plant parts, tobacco, paper and wood pulps, as well as tough plastics or viscous emulsions – in a flash. Uncontrolled wrapping of fibres around the shaft is prevented by the flow-optimised tooth arrangement, ensuring gentle handling of the material and process reliability. Material-related inertness and uncompromising sterilisability The materials science design of the dispersing rod is consistently optimised for maximum chemical resilience and absolute freedom from contamination. All functional elements in contact with the medium are made of high-purity, stainless steel grade 1.4404 (AISI 316L). The shaft is supported by an extremely low-friction and wear-resistant PTFE bearing system. This combination of materials allows for continuous use in aggressive acids, alkalis and organic solvents. To ensure a sterile sampling environment and to completely rule out cross-contamination in multi-user operation, the entire tool can be easily sterilised in an autoclave or cleaned gently with standard disinfectants. Process reliability and convenient system integration The mechatronic system architecture guarantees safe and vibration-free power transmission even at maximum speeds of up to 10,000 revolutions per minute. The dispersing shaft can be quickly and tool-free secured in the T 50 digital drive via the standardised connection. Thanks to the generous immersion depth of up to 250 mm and the fluid-mechanical geometry, the tool is certified for a wide working volume ranging from 0.5 to 20 litres (based on water). This offers laboratory managers and industrial users maximum flexibility when scaling up processes from research to pilot plant scale.

Maximum circulation, minimal air ingress: IKA jet mixing head S 50 N - W 80 SMK The IKA S 50 N - W 80 SMK (MPN 0008006300) is a highly specialised dispersing and mixing tool for the high-performance IKA T 50 digital drive. Whilst conventional dispersing tools are designed for maximum shear forces to break down materials, this jet mixing head (SMK) is designed for efficient mixing and suspension in large volumes ranging from 1 to 50 litres (based on water). The jet mixing principle The geometry of the SMK generates a strong axial flow (from top to bottom or bottom to top, depending on the orientation/direction of rotation). Suspension of powders: Solids are swept up from the bottom of the vessel by the directed liquid jet and distributed homogeneously throughout the liquid. No vortex effect: Unlike simple propeller agitators, the stator tube prevents the formation of a deep vortex. This ensures that no unwanted air is incorporated into the medium – a crucial advantage when producing sensitive emulsions or foaming media. Rapid mixing: Even in large beakers or small vessels (up to 50 litres), the Ø 80 mm stator head ensures rapid and complete circulation of the entire sample. High-quality construction (“N”) The unit is built for heavy-duty, continuous use in laboratories and pilot plants: Materials: All components that come into contact with the medium are made of high-quality stainless steel (AISI 316L). PTFE bearing (“N”): The tried-and-tested, highly chemically-resistant PTFE bearing ensures smooth operation and a long service life. Hygiene: The tool can be easily dismantled for thorough cleaning and is fully autoclavable at 121 °C. Areas of application Chemicals & Cosmetics: Mixing thickeners, powders or pigments into liquids without trapping air. Environmental analysis: Stirring of sediments or sludge samples in large containers. Food technology: Suspending solids in large volumes (e.g. milk powder, cocoa). Pilot plant/scale-up: Preparation of batches for subsequent production.
