AS ONE YKB High-Speed Laboratory Grinder

Overview

The AS ONE YKB High-Speed Laboratory Grinder (Model C3-6661-01) is a precision-engineered, benchtop rotational grinder designed for rapid and reproducible size reduction of dry, brittle, and moderately fibrous solid samples in research, quality control, and analytical laboratories. Operating on the principle of high-velocity impact and shear forces generated by a dynamically balanced spring-steel blade rotating at approximately 28,000 rpm, the YKB delivers consistent particle size distribution across small-batch preparations. Its compact footprint and robust mechanical timer make it particularly suited for routine sample homogenization prior to elemental analysis (e.g., XRF, ICP-OES), moisture content determination, or sieve-based particle size classification. Unlike planetary ball mills or cryogenic grinders, the YKB requires no cooling media or complex milling jars—enabling rapid turnaround between samples with minimal operator intervention.

Key Features

• High-speed rotor assembly engineered for stable operation at ~28,000 rpm, minimizing vibration and thermal buildup during extended use.
• Mechanically actuated 5-minute dial timer with tactile feedback, supporting repeatable processing durations without software dependency.
• 200 mL stainless-steel grinding chamber (SUS430) offering corrosion resistance and ease of cleaning; compatible with alcohol-based decontamination protocols.
• Interchangeable spring-steel blade optimized for hardness and edge retention—designed for dry grinding of pharmaceutical tablets, plant tissues, polymers, ceramics, and mineral powders.
• Aluminum lid handle and reinforced housing provide ergonomic handling and structural integrity during high-torque operation.
• Integrated safety features including grounded 3-pin power cord, thermal cutoff protection, and blade-locking mechanism to prevent accidental activation during loading/unloading.

Sample Compatibility & Compliance

The YKB is validated for use with non-hygroscopic, low-moisture (<10% w/w), and non-oily solid materials—including granules, flakes, pellets, and friable powders. It is not recommended for wet, sticky, oily, or highly elastic samples (e.g., rubber, gels, or thermoplastics above Tg), as these may cause blade clogging or inconsistent comminution. The device complies with JIS C 61010-1:2013 (equivalent to IEC 61010-1) for laboratory electrical equipment safety. While not certified for GMP environments per se, its all-metal construction, absence of lubricants in the grinding path, and cleanable architecture support adherence to GLP documentation practices. Routine maintenance—including carbon brush replacement and blade inspection—is documented in the user manual to ensure long-term repeatability and traceability.

Software & Data Management

The YKB operates as a standalone electromechanical instrument with no embedded firmware, network interface, or digital data logging capability. All operational parameters—including timer setting, run duration, and power state—are manually controlled and visually verified. This analog design eliminates cybersecurity risks, ensures compatibility with regulated environments where software validation is prohibitive (e.g., certain ISO/IEC 17025-accredited labs), and avoids dependencies on operating system updates or driver installations. For laboratories requiring audit trails, external process logs (e.g., paper-based SOP records or LIMS-integrated run sheets) are recommended to document batch number, operator ID, start/stop time, and visual assessment of grind fineness.

Applications

• Preparation of homogeneous subsamples for quantitative elemental analysis (XRF, AAS, ICP-MS).
• Rapid disintegration of pharmaceutical dosage forms (tablets, capsules) prior to dissolution or assay testing per USP <701>.
• Size reduction of geological core fragments or ceramic shards for XRD phase identification.
• Homogenization of dried botanical material (leaves, roots, seeds) for DNA extraction or metabolite profiling.
• Particle size standardization of reference materials used in sieve calibration and laser diffraction validation studies.

FAQ

Can the YKB be used for cryogenic grinding?
No. The YKB lacks liquid nitrogen ports, insulated chambers, or low-temperature-rated components. Cryogenic operation would risk thermal shock to the SUS430 chamber and blade fracture.
Is the grinding chamber autoclavable?
No. SUS430 stainless steel is not suitable for repeated steam sterilization cycles; cleaning is recommended using isopropanol or mild detergent followed by air drying.
What is the expected service life of the included carbon brush?
Under typical usage (≤10 cycles/day), the carbon brush maintains rated performance for approximately 500 operational hours before requiring replacement per manufacturer guidelines.
Does AS ONE provide calibration certificates for the YKB?
No. As a mechanical grinding device without metrological output (e.g., no torque, RPM, or particle size sensors), formal calibration is not applicable. Performance verification is conducted via visual and sieving-based endpoint assessment.
Can third-party blades be installed?
AS ONE does not validate or warrant compatibility with non-OEM blades. Use of unauthorized components may compromise safety interlocks, void warranty, and impair rotational balance.
