Small High Speed Upright Grinder for Laboratory Sample Preparation

Product Overview

This upright high-speed grinder combines a compact footprint with a powerful 0.9 kW motor to deliver exceptionally rapid sample pulverization. Its design focuses on achieving consistent fineness from 30 to 300 mesh in seconds, making it an indispensable tool for laboratories that require fast turnaround and reliable particle size reduction. The unit handles batch capacities from 20 to 200 grams, accommodating both small-scale analytical preparations and moderate-throughput production needs.

Engineered for versatility, it processes a wide array of materials—from hard minerals to fibrous herbs—without the need for pre-crushing or secondary steps. The deep-drawn 304 stainless steel grinding chamber, manufactured using a one-piece drawing process, ensures structural integrity, corrosion resistance, and unmatched hygiene. Fully enclosed operation prevents sample leakage and airborne dust, making this system particularly suitable for cleanrooms, food testing, and toxic material handling.

Backed by years of field-proven reliability across global laboratories, this equipment incorporates intelligent safety features such as an overload fuse and a lid interlock, ensuring operator protection and machine longevity. Its upright configuration minimizes bench space, while intuitive one-button controls require minimal training. Technicians can achieve reproducible results with ease, thanks to the unit’s precision motor balancing and robust mechanical design.

Key Features

• Ultra-High-Speed Motor: The motor spins at 25,000 RPM, delivering the kinetic energy needed to fracture even the toughest materials in under three minutes. This high speed not only reduces processing time but also minimizes heat buildup, preserving heat-sensitive samples such as volatile phytochemicals and low-melting-point compounds.
• Wide-Range Adjustability with Digital Precision: Particle size is controlled simply by setting the grinding duration—from coarse 30 mesh (short bursts) to fine 300 mesh (extended cycles). This stepless adjustability allows operators to dial in exact fineness for downstream processes like HPLC, XRF, or dissolution testing without mechanical adjustments.
• Superior One-Piece Chamber Construction: The grinding chamber is deep-drawn from a single sheet of 304 stainless steel, eliminating weld seams and crevices where contaminants could hide. This seamless interior not only simplifies cleaning but also prevents cross-contamination between batches, critical for multi-user or multi-project labs.
• Integrated Overload Safety Mechanism: A thermal fuse automatically interrupts power if the motor exceeds safe operating limits due to blockages or overloading. This protects the motor windings from burnout and extends the overall service life, while the lid interlock ensures the unit cannot operate unless properly closed.
• Contamination-Free Processing Environment: The chemically inert 304 stainless steel chamber and alloy steel blades resist corrosion from acidic or alkaline samples, safeguarding sample purity. The enclosed design captures all dust, making it ideal for processing hazardous materials or potent active pharmaceutical ingredients (APIs) without exposure risk.
• Ultra-Compact Benchtop Footprint: Measuring just 170 mm wide and 350 mm tall, the upright design occupies minimal counter space, fitting easily into fume hoods, glove boxes, or crowded lab benches. Its 4 kg weight allows effortless relocation from one workstation to another without heavy lifting equipment.
• Quiet and Balanced Operation: Precision dynamic balancing of the rotor and motor assembly keeps vibration levels extremely low, resulting in operating noise under 70 dB. This allows comfortable use in open-plan laboratories where noise distractions must be minimized, and it reduces wear on bearings over time.
• Rapid Disassembly for Easy Maintenance: The removable grinding cup lifts off quickly, and the smooth internal surfaces rinse clean in seconds. This design supports high-throughput workflows where frequent material changeovers are required, such as in contract testing labs or multi-product R&D facilities.
• Versatile Material Compatibility: Designed to grind a broad spectrum of substances—fibrous plant tissues, hard mineral chunks, brittle crystals, and elastic polymers—without requiring separate grinding vessels or blade types. The aggressive blade geometry and high tip speed generate the cutting and impact forces necessary for tough-to-mill materials.
• Energy-Efficient and Cost-Effective: Consuming only 0.9 kW per hour, this grinder delivers powerful performance with low electrical consumption, contributing to reduced operational costs and a smaller carbon footprint. Its durable construction and long-life blades also minimize recurring maintenance expenses.

Applications

Technical Specifications

Note: This grinder is designed for intermittent use; for extended fine grinding, process in short cycles with cooling periods to prevent thermal buildup. Always follow the operating manual for material-specific guidance and safety precautions.

Why Choose This Product

• Field-Proven Durability and Low Total Cost of Ownership: Constructed with heavy-duty motor windings, precision bearings, and a rigid frame, this grinder has undergone accelerated life testing equivalent to 50,000 cycles. Its robust design minimizes downtime and maintenance costs, making it a smart long-term investment for high-throughput labs.
• Precision Engineering for Unmatched Consistency: Every rotor assembly is dynamically balanced to within micron-level tolerances, ensuring vibration-free operation and uniform particle output batch after batch. This consistency reduces analytical variability, giving you greater confidence in your test data.
• Uncompromising Material and Build Quality: The exclusive use of 304 food-grade stainless steel for the chamber and high-carbon alloy steel for blades provides exceptional resistance to corrosion, wear, and chemical attack—guaranteeing sample integrity even with aggressive substances. All materials comply with FDA and EC food-contact regulations.
• Enhanced Safety and Ergonomic Design: Beyond the automatic overload fuse, the magnetic lid interlock prevents startup unless securely closed, while the rubber base pads dampen residual vibrations and protect surfaces. The vertically oriented chamber and ergonomic lid lever facilitate one-handed loading and unloading, reducing operator fatigue.
• Responsive Worldwide Support and Customization Potential: Our global technical support network offers rapid assistance via phone, email, or remote diagnostics. We also provide blade re-sharpening services and, for specialized needs, can engineer custom grinding chamber volumes, coatings, or control packages.
