Tap Density Testers - QualiTAP™ Series – Precision Bulk Density Measurement for Powders

Qualitest’s QualiTAP™ Series Tap Density Testers, also known as Tapped Density Testers, are engineered for precise, repeatable measurement of the tapped density and bulk density of powders, granules, and other particulate materials. Designed to meet the most stringent pharmaceutical, industrial, and laboratory standards, these instruments ensure accuracy, reliability, and full regulatory compliance.

Our range includes single-station (QualiTAP™ 100), dual-station (QualiTAP™ 200), and triple-station (QualiTAP™ 300) models, giving you flexibility to match throughput requirements without compromising precision.

Applications Across Industries

While tap density testing is critical in the pharmaceutical industry, it is also widely used in:

  • Chemical and material science – characterization of powders for processing and quality control
  • Metal and ceramic processing – evaluating powder packing behavior in manufacturing
  • Food industry – analyzing ingredient flow and compaction properties
  • Energy materials – testing battery powder density and uniformity
  • Environmental engineering – evaluating particulate properties for research and analysis
  • Academic and industrial laboratories – supporting R&D and compliance verification

Importance in the Pharmaceutical Industry

In pharma manufacturing, tapped density measurement is essential for:

  • Formulation development – optimizing powder blends for consistent tablet and capsule production
  • Quality control – ensuring powder flowability, compressibility, and uniformity across batches
  • Regulatory compliance – meeting USP, EP, and ISO requirements for powder characterization
  • Process optimization – improving dosing, filling, and packaging efficiency

Standards Compliance

The QualiTAP™ Series fully complies with major international standards, including:

  • USP <616> – Bulk Density and Tapped Density of Powders
  • EP 2.9.34 – European Pharmacopoeia Tapped Density of Powders
  • ISO 3953 – Determination of bulk density and tapped density
  • ASTM B527 – Tapped density of metal powders and compounds

Available Models

  • QualiTAP™ 100 – Single-station tap density tester for standard throughput labs
  • QualiTAP™ 200 – Dual-station high-efficiency model for medium-to-high throughput
  • QualiTAP™ 300 – Triple-station solution for maximum productivity in busy laboratories

The QualiTAP™ Series combines advanced engineering, regulatory compliance, and intuitive operation to deliver accurate, repeatable powder density results every time.
