IKA Tube Mill 100 control Benchtop Cryogenic Grinding Mill

Overview

The IKA Tube Mill 100 control is a compact, high-speed benchtop cryogenic grinding mill engineered for reproducible, controlled size reduction of temperature-sensitive and brittle materials. It operates on the principle of high-energy impact and shear forces generated by rapid rotation of a stainless-steel grinding element inside a sealed, interchangeable tube—enabling efficient comminution without thermal degradation. Designed for laboratories requiring precise, repeatable sample preparation prior to elemental analysis, XRD, SEM, or polymer characterization, the Tube Mill 100 control delivers consistent particle size distribution across batches while supporting dry ice cooling to maintain sub-ambient temperatures during operation. Its robust architecture, compliant with DIN EN 60529 (IP 30), ensures safe operation in standard laboratory environments (5–40 °C, ≤80 % RH), and its modular grinding cup system allows seamless adaptation to varying sample volumes and physical properties.

Key Features

• Stepless electronic speed control from 5000 to 25,000 rpm, enabling fine-tuned energy input for diverse material classes—from soft polymers to moderately hard minerals (up to 5 Mohs hardness)
• Integrated multilingual OLED display with real-time parameter feedback, diagnostic error codes, and intuitive touch-key navigation
• Programmable timer (5 seconds to 3 minutes) supporting both continuous and intermittent grinding cycles to minimize heat accumulation
• USB interface for bidirectional communication: remote parameter control, full experimental data logging (speed, time, cycle count, errors), and method export/import for audit-ready documentation
• Cryogenic compatibility: grinding chamber accommodates dry ice placement directly adjacent to the sample tube, preserving thermolabile analytes and inhibiting agglomeration
• Three included grinding cups—MT 40 (40 mL capacity), MT 100 (100 mL), and MMT 40 (micro-volume, 40 mL with enhanced sealing)—each precision-machined from stainless steel for durability and minimal contamination
• User-configurable safety limits: maximum rotational speed and run duration are programmable to prevent mechanical overload or unintended overgrinding

Sample Compatibility & Compliance

The Tube Mill 100 control accepts feed particles up to 10 mm in diameter and processes samples with hardness ≤5 Mohs on the Mohs scale—including plant tissues, pharmaceutical tablets, plastics, ceramics, and geological specimens. Its sealed grinding system minimizes cross-contamination and airborne particulate release, aligning with ISO 17025 requirements for sample integrity in accredited testing labs. The instrument meets CE marking criteria under the EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. While not inherently GLP- or FDA 21 CFR Part 11–compliant out-of-the-box, its USB data logging, method storage, and timestamped error reporting support traceability frameworks required for regulated environments when integrated into validated SOPs.

Software & Data Management

No proprietary software installation is required—the Tube Mill 100 control appears as a virtual COM port upon USB connection, allowing direct integration with Lab Information Management Systems (LIMS) or custom Python/MATLAB scripts via standard serial protocols. All operational parameters—including start/stop timestamps, actual speed profiles, total runtime, and fault events—are recorded in CSV-compatible format. Up to ten user-defined methods can be stored internally, each retaining independent settings for speed, duration, mode (continuous/intermittent), and safety thresholds. Audit trails are preserved locally on-device memory and exported on demand, facilitating internal quality reviews and external regulatory assessments.

Applications

• Preparation of homogenized powders for X-ray fluorescence (XRF) and inductively coupled plasma (ICP-OES/MS) analysis
• Reduction of freeze-dried biological samples (e.g., lyophilized tissue, microbial pellets) without denaturation
• Generation of uniform polymer granules for melt flow index (MFI) testing per ASTM D1238
• Size reduction of brittle ceramics and refractory oxides prior to laser diffraction particle sizing (ISO 13320)
• Routine QC grinding of pharmaceutical excipients and active ingredients under cGMP-aligned workflows
• Fragmentation of composite materials for SEM-EDS cross-sectional analysis

FAQ

Can the Tube Mill 100 control be used with liquid nitrogen?

No—it is specifically designed for dry ice cooling only; LN₂ may cause thermal shock to the grinding cups or O-ring seals.
Is calibration required before first use?

No routine calibration is specified by IKA; however, speed accuracy (±2 %) is factory-verified and traceable to national standards.
What maintenance intervals are recommended?

Visual inspection of grinding cups and O-rings before each use; lubrication-free operation eliminates scheduled bearing maintenance.
Does the device support automatic restart after power interruption?

No—safety-critical design mandates manual re-initiation following any power loss.
Are additional grinding cups available separately?

Yes—MT 20, MT 50, and specialized cryo-compatible variants are offered as optional accessories through authorized IKA distributors.
