J. Engelsmann AG Jolting Volumeter STAV 11 for Bulk Solids Density Testing

The J. Engelsmann AG Jolting Volumeter STAV 11 is a specialized laboratory instrument designed for accurate assessment of the apparent and tapped volumes of bulk solids, powders, granulates, and fibrous materials. This compact volumeter enables calculation of tamped density by measuring before and after compaction volumes, essential for molecular diagnostics, bioprocessing, and biopharmaceutical production workflows.

Key technical features include:

• Adjustable jolting mechanism allowing customized tamping stroke counts beyond default settings, providing flexibility in sample compaction protocols for diverse material types.
• Interchangeable measurement cylinders ranging from 10 ml to 1000 ml, commonly supplied with a 250 ml standard cylinder; cylinders are secured using a robust retaining ring and gasket to ensure repeatable measurements.
• Compliance with critical industry standards including European Pharmacopoeia, DIN ISO 787 Part 11, ISO 3953, ISO 8967, and ASTM B 527-93, ensuring reliable data for synthetic biology research and pharmaceutical quality control.
• User-friendly operation through an intuitive display and control unit combined with a modern "soft design" frame that facilitates easy cleaning and maintenance—a crucial aspect in clinical diagnostic and biotechnology laboratory environments.
• Optional sound-absorption hood accessory available for quieter operation, improving ergonomic conditions for long-term laboratory use.

Widely used in quality assessment of powders and bulk solids, the STAV 11 is integral to biomanufacturing and molecular cloning workflows, delivering precise volumetric data critical in cell imaging reagent production and formulation development. Its adaptability and compliance make it highly valued across biotechnology and pharmaceutical laboratories seeking standardized bulk density testing solutions.
