Product information "IKA S 10 D - 7 G - KS - 110 plastic dispersing tool, 24 pieces, 0020002075"

High-shear kinetics on an analytical micro-scale

In molecular biological sample preparation (such as RNA/DNA extraction) and cellular analysis, the physical disruption of soft tissue in the low millilitre range is the fundamental first step in the process. The IKA S 10 D - 7 G - KS - 110 dispersing tool (geometrically specified with a 7 mm stator diameter) transfers the immense kinetic energy of the T 10 basic drive precisely into this microenvironment. The fluid dynamics principle is based on high-speed rotor-stator technology. The liquid medium is drawn into the dispersing head axially and forced through the geometrically defined slots in the stator (G version) by the rotating inner shaft with extreme radial acceleration. The resulting massive hydrodynamic shear stresses and high-frequency pressure fluctuations (cavitation) shatter cell membranes in fractions of a second and convert tissue samples into absolutely homogeneous cell suspensions.

Rheological adaptation to conical reaction vessels

The fluid dynamics of the dispersion are significantly limited by the geometry of the sample vessel. With a shaft length of 110 mm and a diameter of exactly 7 mm, the S 10 D - 7 G - KS - 110 tool is fluid-dynamically designed to operate in standard conical reaction vessels (such as 1.5 ml microcentrifuge tubes or 15 ml Falcon tubes). Thanks to the optimised gap geometry between the rotor and stator, the sample volume (1 to 20 ml H₂O) is circulated turbulently without causing an excessive vortex effect that would draw process-damaging atmospheric oxygen into the medium or eject the sample from the tube.

Physical elimination of molecular carry-over

When processing PCR matrices, forensic traces or highly infectious tissue, microscopic sample carry-over from one batch to the next represents an absolute analytical disaster. Conventional stainless-steel dispersing tools require thermodynamically and chemically intensive decontamination after each process step in order to completely destroy nucleic acid fragments. IKA plastic tools (KS series) solve this critical contamination problem physically by virtue of their design as single-use (or limited-use) tools. After homogenisation of a critical sample, the entire tool is discarded or autoclaved separately. Cross-contamination between serial measurement runs is thus 100 per cent ruled out at the molecular level.

Polymer integrity and biocompatible materials

To ensure the structural integrity of the dispersing head at speeds of up to 30,000 revolutions per minute, the KS tools are made from high-performance, biocompatible thermoplastic polymers (such as polycarbonate/polyethersulphone). These plastics are characterised by high torsional stiffness and mechanical abrasion resistance. During short-term high-shear processes, they do not release any toxic plasticisers or disruptive microparticles into the analytical matrix.

Individual requirements & accessories

The plastic dispersing tools of the KS series require the IKA T 10 basic high-performance drive for process operation. Due to the frictional heat generated in the polymer shear gap at speeds of up to 30,000 rpm, KS tools are not designed for extensive continuous operation and should be treated as consumables to ensure analytical purity in the laboratory at all times. Please contact our procurement service at any time regarding the strategic procurement of laboratory consumables.

IKA T 10 basic ULTRA-TURRAX Dispergierer, 0,5 bis 100 ml, bis 30.000 rpm, 0003737000, Produktansicht
IKA T 10 basic ULTRA-TURRAX disperser, 0.5 to 100 ml, up to 30,000 rpm, 0003737000
Herstellernummer: 0003737000

The IKA T 10 basic ULTRA-TURRAX is a hand-held disperser for small sample volumes of between 0.5 and 100 millilitres (H₂O). The unit is powered directly from the 230-volt mains supply, requires no battery and is ready for use immediately upon plugging it in. The speed is infinitely variable from 8,000 to 30,000 revolutions per minute, allowing it to process both low-viscosity aqueous samples and thicker emulsions up to 5,000 mPas.Continuously variable speed via the scale displayOn the T 10 basic, the speed is read from a scale on the housing; the battery-powered ‘battery’ version displays it digitally. This is sufficient for a procedure where the same mark can always be selected, and operation remains simple. When plugged in, the unit draws 125 watts, 75 watts of which are delivered to the motor. A duty cycle of 10 minutes followed by a 5-minute pause protects the motor from overheating during longer production runs.Tool change without additional toolsThe arm has a diameter of 8 millimetres and a length of 100 millimetres. The dispersion tool can be removed without any additional tools using the quick-release coupling. Stainless steel dispersion tools are dismantled and cleaned individually for this purpose, whilst the disposable plastic tools, available in two sizes, come ready-assembled from the packaging and are disposed of after use. This reduces the cleaning effort required between two samples and prevents cross-contamination, for example in PCR analysis. No dispersing tool is included in the scope of delivery; it is selected separately to suit the application.Compact and lightweight for manual operationMeasuring 178 millimetres in length, 56 in width and 66 in depth, the T 10 basic fits comfortably in the hand. Weighing 0.61 kilograms, the device can be held for extended periods without causing fatigue; the noise level without an attachment fitted is 65 dB(A).For different mains voltagesIn addition to the standard 230-volt version, IKA also supplies the same unit in 115-volt and 100-volt versions, for countries outside the European mains supply or for branch sites with different mains voltages. The IP 30 protection rating in accordance with DIN EN 60529 and a permissible operating range of between 5 and 40 degrees Celsius at up to 80 per cent relative humidity are sufficient for normal day-to-day laboratory use, although the unit is not designed for use outdoors or in damp rooms.Typical applicationsHomogenisation of small tissue samples prior to further extractionPreparation and fine dispersion of emulsions and suspensions on a micro-scaleSample preparation for PCR analysis using disposable plastic instrumentsRoutine tasks in teaching and training where a robust instrument that does not require battery maintenance is requiredSelection guide: basic or battery?The T 10 basic runs exclusively on mains power and therefore always requires a power socket within reach. For those who wish to use the disperser under a fume cupboard or on the move without a cable, the T 10 battery ULTRA-TURRAX is the battery-powered variant of the same series, albeit with lower motor power and a lower viscosity limit of 200 mPas. For mobile use with suitable accessories, there are also three kits available, such as the T 10 battery Portable Solution or the T 10 battery Tissue Safe Solution with disposable tools for tissue samples.Technical detailsMotor power input / output125 W / 75 WProcessable volume (H₂O)0.5 to 100 mlMax. viscosity5,000 mPasSpeed range8,000 to 30,000 rpm, continuously variableSpeed displayScaleNoise level without tools65 dB(A)Boom diameter / boom length8 mm / 100 mmDuty cycleON 10 mins, OFF 5 minsPermissible ambient temperature / humidity5 to 40 °C / 80 %Protection classIP 30 in accordance with DIN EN 60529Dimensions (W x H x D)56 x 178 x 66 mmWeight0.61 kgPower rating230 V, 50/60 Hz, 125 W (other voltage options: 115 V / 100 V)ContentsT 10 basic ULTRA-TURRAX drive unit, ID No. 0003737000R 200 clamp, ID No. 0003372000A dispersing tool is not included in the scope of delivery and must be selected separately from the range of accessories to suit the application.Regulatory informationThis unit is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).
