IKA Tube Mill 100 control, single-use mill, 100 ml, 25,000 rpm, 0020007144

Tribological degradation and preventive maintenance The reusable grinding chambers of the IKA Tube Mill series (MMT 40.1 and MMT 100.1) operate at the extreme limits of mechanical capability. Rotational speeds of up to 25,000 revolutions per minute, combined with highly abrasive sample matrices (such as mineral ores or rocks), generate massive tribological friction forces on the dynamic sealing elements and mechanical bearings. This continuous stress inevitably leads to gradual degradation of the elastomers and microscopic wear on the rotating contact surfaces. The IKA A-MMT.100 spare parts kit restores the grinding chamber’s original kinematic and thermodynamic integrity by replacing the system’s process-critical wear parts before metrological or mechanical failure of the batch occurs. Restoration of system hermeticity and aerosol containment A fundamental safety consideration in the dry grinding of toxic, biohazardous or highly potent active pharmaceutical ingredients (APIs) is the prevention of leaks. If the elastomeric seals become brittle due to thermomechanical stress, the grinding chamber loses its function as a hermetic containment system. Microscopically fine, respirable dust (aerosols) could escape into the laboratory environment through the compromised O-rings. The preventative replacement of the sealing elements using the A-MMT.100 set restores this critical physical barrier and supports the protection of the user in line with applicable occupational safety regulations. Kinematic stabilisation and resonance suppression Worn mechanical components within the grinding chamber axis not only cause leaks but also generate fluid dynamic imbalances. This eccentricity of the rotating shaft leads to high-frequency vibrations, which place a strain on the Tube Mill’s magnetic drive and exponentially increase thermodynamic friction (exothermic reaction) within the sample chamber. The installation of brand-new replacement parts ensures that the drive shaft is once again precisely coaxially aligned. This mechanical resonance suppression ensures that the kinetic energy flows loss-free into the impact comminution of the sample and that the analytical reproducibility of the particle size distribution is permanently maintained. Technical details Product type: Spare parts set / Wear parts kit (Maintenance Kit) Process function: Restoration of dynamic system hermeticity Tribological focus: Compensation for mechanical wear on sealing elements Kinematics: Coaxial stabilisation of the drive shaft Occupational safety: Restores hermetic aerosol containment Quality assurance: Supports reproducible grinding results Compatibility: Suitable exclusively for IKA MMT 40.1 and MMT 100.1 (reusable grinding chambers) Scope of delivery 1 x IKA A-MMT.100 spare parts set (Important note: The MMT grinding cups and the Tube Mill drive unit are not included in the scope of delivery!) Individual requirements & accessories The reusable MMT 40.1 and MMT 100.1 systems offer a high degree of analytical flexibility; however, unlike single-use cups (MT series), they require strict adherence to maintenance intervals. To prevent cross-contamination (carry-over) and mechanical failure, wear parts must be replaced at regular intervals depending on the abrasiveness of the sample matrix. For laboratories processing high volumes of hard rock samples, we recommend always keeping several spare parts kits in stock to ensure that the ongoing analytical workflow is not interrupted by safety-related downtime. Please contact our procurement service at any time regarding the strategic procurement of maintenance kits.

Kinetics of impact comminution at scaled-up volume In the analytical sample preparation of hard, brittle and dry matrices (such as rocks, mineral solids or agricultural products), the application of substantial mechanical energy is essential. The IKA MT 100 single-use grinding cups apply the process principle of high-speed impact and percussion comminution to a significantly increased working volume of 100 ml. A solid stainless-steel beater is permanently integrated at the geometric centre of the chamber. Driven by the magnetic coupling of the IKA Tube Mill base station at up to 25,000 revolutions per minute, this rotor transfers immense kinetic energy to the solids. The enlarged chamber geometry creates enhanced three-dimensional flow turbulence, which continuously circulates the material into the impact zone. The resulting shock waves overcome the molecular binding forces of the sample and transform it into an analytically homogeneous, fine-powdered matrix. Polymer physics and thermomechanical integrity The high-speed comminution of extremely hard samples in larger batches induces a significantly increased thermodynamic load (exothermic reaction) due to friction and massive wall collisions. The MT 100 grinding cups are manufactured from high-performance thermoplastic polymers that exhibit extreme torsional stiffness and structural ballistic impact resistance. This specific polymer matrix is physically engineered to withstand the massive kinetic impacts of large rock fragments or pellets without undergoing plastic deformation (fracture prevention). At the same time, the material integrity ensures that, even under the increased thermal load of the 100-ml volume, no interfering plasticisers or polymer particles are released into the analytical matrix. Aerosol containment and elimination of carry-over When grinding toxic, biohazardous or highly potent active pharmaceutical ingredients (APIs) in large quantities, preventing uncontrolled aerosol formation is an absolute safety priority. The MT 100 grinding cup functions as a hermetically sealed containment system. The process takes place in a completely sealed atmosphere, thereby physically protecting the user from respirable fine dust. The fundamental metrological design principle as a ‘single-use’ vessel also guarantees that analytical cross-contamination (carry-over of DNA fragments or chemical traces) between consecutive batches is completely eliminated. The cleaning, which is demanding in terms of thermodynamics and time, of conventional stainless-steel grinding chambers is no longer required, which significantly speeds up the workflow in the laboratory. Technical details Product type: Disposable grinding cup / single-use milling tube Processing principle: Impact and shock comminution (dry milling) Maximum usable volume: 100 ml Integrated tool: Permanently fitted standard stainless steel beater Material: Impact-resistant, transparent, high-performance thermoplastic Analytical focus: Protection against cross-contamination (carry-over) Workplace safety: Hermetic containment against toxic dusts and aerosols Compatibility (drive): Suitable exclusively for the IKA Tube Mill (control / 100) Packaging unit (PU): 10 pieces per set Scope of delivery 10 x IKA MT 100 disposable grinding cups (100 ml) (Important note: The IKA Tube Mill drive unit is not included in the scope of delivery!) Individual requirements & accessories The MT 100.10 grinding cups are dedicated single-use consumables and function exclusively in combination with the IKA Tube Mill drive system. The 100 ml capacity is optimal for representative cross-sectional analyses of larger sample volumes, where a 40 ml cup could lead to statistical deviations. For laboratories with extremely high sample throughput, it makes sense from both a metrological and economic perspective to stock the cups in bulk packs of 50 or 100 (e.g. MT 100.50) to avoid interrupting the continuous workflow. Please contact our specialist procurement service at any time for strategic demand planning.

Kinetics of impact comminution on a scaled macro-scale In clinical diagnostics, agricultural science and molecular biological sample preparation, the physical disruption of larger batches of tissue or solid materials (such as bone fragments, infected plant material or seeds) is a process-critical step. The IKA MT 100 sterile disposable grinding cups operate on the process principle of high-speed impact and percussion comminution and extend the working chamber to an isolated 100-ml volume. A solid stainless-steel beater is permanently integrated at the geometric centre of the chamber. Driven by the magnetic coupling of the IKA Tube Mill base station at up to 25,000 revolutions per minute, this rotor shatters macroscopic tissue and cell structures in fractions of a millisecond. The hydrodynamic turbulence (vortex) generated by the expanded volume transforms even larger samples into an analytically homogeneous, fine-powdered matrix that is optimally accessible for subsequent DNA/RNA extraction. Biological integrity and industrial sterilisation In PCR-based trace analysis or forensic investigations of representative cross-sectional samples, even the slightest presence of foreign nucleic acids or microbial enzymes (DNases/RNases) leads to a catastrophic metrological false-positive result. The MT 100 sterile cups are pre-sterilised using a highly controlled industrial process. This physico-chemical process completely breaks down the macromolecular structure of potential biological contaminants inside the grinding chamber. The thermoplastic polymer matrix of the cup is designed to withstand these sterilisation stresses without any degradation of its structural and ballistic impact resistance, thereby guaranteeing absolute genetic purity (blank value) for the primary analysis buffer in large volumes. Bioaerosol containment and elimination of carry-over High-speed grinding of infectious samples or highly potent active pharmaceutical ingredients generates significant fluid dynamic turbulence and internal pressure spikes, leading to the formation of respirable bioaerosols. The MT 100 sterile grinding cup functions as a hermetically sealed bio-containment system. The process takes place in a completely enclosed atmosphere, thereby physically protecting the user from airborne pathogens. The fundamental design principle as a sterile ‘single-use’ vessel also guarantees that analytical cross-contamination (carry-over) between consecutive patient or environmental samples is completely eliminated, as the error-prone and thermodynamically demanding decontamination of conventional stainless-steel grinding chambers is no longer required. Technical details Product type: Sterile disposable grinding cup / sterile single-use milling tube Processing principle: Impact and shock comminution on a macro scale Maximum usable volume: 100 ml Microbiological status: Industrially sterilised (to prevent genetic contamination) Integrated tool: Permanently fitted standard stainless steel beater Material: Impact-resistant, transparent, high-performance thermoplastic Health and safety: Hermetic containment against infectious bioaerosols Compatibility (drive): Exclusively compatible with the IKA Tube Mill (control / 100) Packaging unit (PU): 10 pieces per set (supplied sterile-packed) Scope of delivery 10 x IKA MT 100 sterile disposable grinding cups (100 ml) (Important note: The IKA Tube Mill drive unit is not included in the scope of delivery!) Individual requirements & accessories The MT 100.10 sterile grinding cups are highly specialised consumables for large-volume molecular biology or clinical workflows and function exclusively in combination with the IKA Tube Mill drive system. For high-throughput forensic laboratories, pandemic reference centres or in agricultural genetics, where representative sample sections of up to 100 ml need to be processed in a standardised manner, scaling up to large-volume containers (e.g. MT 100.50 sterile) is both economically and logistically advisable. Please contact our specialist procurement service at any time regarding the establishment of framework agreements and the strategic procurement of sterile bulk containers.

Kinetics of impact comminution at larger scale In the analytical sample preparation of hard, brittle and dry matrices (such as rocks, mineral solids or agricultural products), the application of substantial mechanical energy is essential. The IKA MT 100 single-use grinding cups apply the process principle of high-speed impact and percussion comminution to a significantly increased working volume of 100 ml. A solid stainless-steel beater is permanently integrated at the geometric centre of the chamber. Driven by the magnetic coupling of the IKA Tube Mill base station at up to 25,000 revolutions per minute, this rotor transfers immense kinetic energy to the solids. The enlarged chamber geometry creates enhanced three-dimensional flow turbulence, which continuously circulates the material into the impact zone. The resulting shock waves overcome the molecular binding forces of the sample and transform it into an analytically homogeneous, fine-powdered matrix. Polymer physics and thermomechanical integrity The high-speed comminution of extremely hard samples in larger batches induces a significantly increased thermodynamic load (exothermic heat build-up) due to friction and massive wall collisions. The MT 100 grinding cups are manufactured from high-performance thermoplastic polymers that exhibit extreme torsional stiffness and structural ballistic impact resistance. This specific polymer matrix is physically engineered to withstand the massive kinetic impacts of large rock fragments or pellets without undergoing plastic deformation (fracture prevention). At the same time, the material integrity ensures that, even under the increased thermal load of the 100-ml volume, no interfering plasticisers or polymer particles are released into the analytical matrix. Aerosol containment and elimination of carry-over in high-throughput applications When grinding toxic, biohazardous or highly potent active pharmaceutical ingredients (APIs) in large quantities in a batch process, preventing uncontrolled aerosol formation is an absolute safety priority. The MT 100 grinding cup functions as a hermetically sealed containment system. The process takes place in a completely enclosed atmosphere, thereby physically protecting the user from respirable fine dust. This pack of 50 units is precisely tailored to the high-throughput requirements of medium to large laboratories. The fundamental metrological design principle of a ‘single-use’ vessel guarantees that analytical cross-contamination (carry-over of DNA fragments or chemical traces) between consecutive batches is completely eliminated. The energy- and time-intensive cleaning of conventional stainless steel grinding chambers is no longer necessary, which significantly speeds up the analytical workflow.

Individual requirements & accessories The MT 100.50 grinding cups are dedicated single-use consumables and function exclusively in combination with the IKA Tube Mill drive system. The 100 ml capacity is ideal for representative cross-sectional analyses of larger sample volumes, where a 40 ml cup could lead to statistical deviations. The pack of 50 offers the ideal logistical balance between storage space requirements and an uninterrupted process chain. Please contact our specialist procurement service at any time for strategic demand planning, call-off orders or the procurement of even larger volume units.

Kinematics of impact comminution on a scaled macro-scale In the analytical sample preparation of brittle, hard or fibrous matrices, the application of substantial kinetic energy is essential. The IKA MMT 100.1 grinding beaker utilises the process principle of high-speed impact and shock comminution and applies this to a significantly expanded working volume of 100 ml. Designed as a reversible, reusable system, a solid stainless-steel beater rotates at the geometric centre of the chamber. Driven by the magnetic coupling of the IKA Tube Mill base station at up to 25,000 revolutions per minute, the scaling to 100 ml generates intense three-dimensional flow turbulence (vortex). These hydrodynamic vectors continuously force even large sample volumes into the active impact zone. The design as a reusable vessel requires precise metrological cleaning after each batch to avoid analytical cross-contamination (carry-over) in large-volume analyses. Thermomechanical stability and tribological reversibility The repeated high-speed comminution of large and hard sample quantities induces a significant, cyclic thermodynamic load (exothermic reaction) due to friction and massive wall collisions. The MMT 100.1 grinding chamber is manufactured from a structurally cross-linked, high-performance thermoplastic. This specific macromolecular polymer matrix is engineered to withstand the kinetic impacts of large rock fragments or pellets without undergoing plastic deformation. At the same time, the polymer resists chemical and thermal degradation during repeated mechanical cleaning (dishwasher-safe). However, the rotating drive shaft and the dynamic sealing elements are subject to natural tribological wear under continuous abrasive stress on this macro scale, which makes preventive maintenance essential. Sealing and maintenance During the grinding of toxic, biohazardous or highly potent active pharmaceutical ingredients (APIs) on a 100-ml scale, the rotor generates increased internal pressure peaks due to the expanded chamber volume. The tightness of the chamber should be checked after numerous rinsing and grinding cycles. Technical details Product type: Reusable grinding beaker / Multi-Use Milling Tube Processing principle: Impact and shock comminution on a macro scale Maximum usable volume: 100 ml Integrated tool: Permanently fitted standard stainless steel beater Material: High-temperature and chemical-resistant polymer Hygiene and cleaning: Fully dishwasher-safe (machine-washable) Maintenance: Dynamic seals and bearing components are interchangeable Compatibility (drive): Suitable exclusively for the IKA Tube Mill (control / 100) Scope of delivery 1 x IKA MMT 100.1 reusable grinding beaker (100 ml) (Important note: The IKA Tube Mill drive unit is not included!) Individual requirements & accessories The MMT 100.1 reusable grinding beaker is the ideal process engineering solution for laboratories that carry out representative cross-sectional analyses of large sample volumes and have validated cleaning protocols in place. It is essential to note that the dynamic elastomer seals in the rotational axis are subject to wear due to the significant centrifugal and shear forces generated by the 100 ml batch. To prevent leaks or irregular kinematics, these wear parts must be replaced at regular intervals. For this purpose, use only the original IKA A-MMT.100 spare parts kit (item no. 0020003378). Please contact our procurement service at any time regarding the strategic procurement of spare parts.

Kinetics of impact comminution on an enlarged scale and its relevance to materials science In the analytical sample preparation of hard, brittle matrices (such as rocks, soil samples or mineral solids), the application of substantial mechanical energy is essential. The IKA MTT 100 single-use grinding beakers operate on the process engineering principle of high-speed impact and shock comminution and extend the isolated working chamber to a large volume of 100 ml. Driven by the magnetic coupling of the IKA Tube Mill base station at up to 25,000 revolutions per minute, the integrated rotor transfers immense kinetic energy to the solids. The enlarged chamber geometry creates enhanced three-dimensional flow turbulence (vortex), which continuously forces representative cross-sections of the sample into the impact zone. However, the key process-engineering modification of this beaker lies in the material properties of the impact tool: it is made of solid titanium rather than conventional stainless steel. Metallurgical interference and abrasion prevention A fundamental mechanical problem when comminuting hard, abrasive samples is tribological tool wear, which is further exacerbated on a macroscale (100 ml) by the increased particle collision rate. Collisions between the matrix and a conventional stainless steel beater inevitably lead to metallic abrasion. This introduction of foreign ions (specifically iron, chromium and nickel) causes significant spectroscopic interference and metrological errors in sensitive trace analysis (such as AAS, ICP-OES or ICP-MS). The use of the MTT 100 titanium beater avoids this introduction of foreign metals from the stainless steel beater. Single-use vessel and carry-over on a macro scale The high-speed grinding of extremely hard samples induces significant thermodynamic stress (exothermic reaction). The chamber wall, made of high-performance thermoplastic, absorbs these kinetic impacts and thermal loads from the 100-ml batch without fracturing. As a ‘single-use’ vessel, the beaker reduces the risk of analytical cross-contamination (carry-over) between consecutive batches, as the decontamination of conventional grinding chambers is no longer required. Technical details Product type: Disposable grinding beaker / Single-Use Milling Tube Tool geometry: Permanently fitted standard beater made of pure titanium Processing principle: Impact and percussion comminution on a macro scale Maximum usable volume: 100 ml Material (vessel): Impact-resistant, transparent, high-performance thermoplastic Analytical focus: no stainless steel abrasion (Fe, Cr, Ni) in trace analysis Compatibility (drive): Exclusively compatible with the IKA Tube Mill (control / 100) Packaging unit (PU): 10 pieces per set Scope of delivery 10 x IKA MTT 100 disposable grinding beakers (titanium beater, 100 ml) (Important note: The IKA Tube Mill drive unit is not included in the scope of delivery!) Individual requirements & accessories The MTT 100.10 grinding beakers are highly specialised consumables for the analytical solid-state spectroscopy of representative cross-section samples. The metrological selection of the correct beaker is essential: for large-volume standard grinding operations where the iron content of the sample is irrelevant, opt for the standard MT 100 beaker (stainless steel beater) for economic reasons. However, as soon as element-specific trace analysis on an enlarged scale is required, switching to the MTT version with a titanium rotor described here is recommended in order to avoid systematic measurement errors caused by stainless steel abrasion.
