Pulvette Pulva-Sizer™ 3/4 - 1 HP
For researchers, laboratories and quality control departments that demand precise, small-scale grinding with minimal sample loss, the Pulvette Pulva-Sizer™ from Pulva Corporation is the definitive solution. We have engineered this machine for excellence, delivering the same precision and reliability as our larger industrial pulverizers in a compact footprint.
Since 1938, we have
built and supplied pulverizing equipment that reduces materials, such as pharmaceutical powders, to fine, uniform particle sizes, streamlining analytical testing.

The Pulvette Pulva-Sizer
Optimized for lower energy consumption and consumable expenses, the Pulvette Pulva-Sizer is the ideal R&D sample grinding equipment for your lab, pilot plant or testing facility.
Our analytical testing mini pulverizer addresses:
- Sample cross-contamination: The rapid, tool-free access to all internal components enables quick, thorough cleaning between batches, promoting sample purity and reducing the risk of costly re-testing. Since our small sample pulverizer is made of stainless steel, it facilitates purity and prevents contamination.
- Inconsistent particle size: A high-speed rotor of 14,000 RPM, combined with a durable screen, forces the material to a uniform size, making our pulverizer ideal for achieving accurate analytical results in methods such as chromatography.
- Material grinding inefficiency: The Pulvette features six forged "T" style hammers for general use, with optional Blade style hammers for fibrous or specific materials, optimizing your grinding process.
- Process inflexibility: Our solution handles the dry grinding and wet milling of slurries, providing the versatility needed for a wide range of R&D projects.
Operational Workflow With Our Pulvette
Discover how our small sample pulverizer works:
- Material feed: Introduce the material into the grinding chamber via the precision feed screw or, for larger particles, the optional gravity feed hopper.
- High-impact grinding: Inside, the high-speed rotor assembly impacts the material with its swinging hammers.
- Precise sizing: Only particles that are fine enough to pass through the screen openings can exit the grinding chamber.
- Collection: Pick up the finished, uniform-sized product for analysis.
Our Mini Pulverizer in Action
Engineered for precision and versatility, the Pulvette is the ideal choice for laboratory analysis, small batch production, R&D projects and quality control testing. It enables accuracy and discovery across different industries. Below are several application examples:
- Pharmaceuticals and cosmetics: As a pharmaceutical laboratory-scale pulverizer, it is essential for early-stage drug development, formulation and bioavailability studies. It allows your team to mill active pharmaceutical ingredients (APIs) into a precise, uniform size. In cosmetics, our pulverizer grinds pigments and minerals to achieve the desired texture and quality.
- Food science and agriculture: For quality control departments, the Pulvette mills ingredients for nutritional content analysis, texture testing and shelf-life studies. In agriculture, it prepares soil, fertilizer and crop samples for compositional analysis to promote product quality and effectiveness.
- Chemicals and polymers: Our laboratory sample preparation pulverizer prepares samples for analysis, tests reaction precursors and develops new materials. Its ability to create homogenous samples is vital for achieving reliable and repeatable experimental results.
