A laboratory balance enclosure provides containment of powders, particulates, vapors, and fumes for weighing procedures in weighing scales. A balance enclosure is found in almost all laboratories especially in pharmaceutical, chemical, biological, and toxicological laboratories. Laboratory balance enclosures are designed to protect the operator during the weighing process with the help of internal fans that provide constant airflow into the system. Filters will trap powders and fumes to allow filtered, clean air back into the laboratory. Airflow within the system will vary between model and depend on type of filters used.
