Weighing Units for the Protection of Products and Individuals

Weighing Unit

The weighing unit, also called weighing unit, is used to protect individuals and products when handling hazardous substances. The downward-directed pure air flow makes the weighing cabin suitable for manual dispense processes of powdered input materials in a microbiologically controlled production environment. The large-scale laminar flow region completely covers the working area of weighing for scales, and primary and secondary containers. The hygiene-optimised design ensures microbiological safety. The weighing unit are made of V2A stainless steel 1.4301. The purity class corresponds to class A according to EG GMP Guidelines, Annex 1 or purity class 5 according to DIN EN ISO 14644-1.
