NEW Esco PowderMax Powder Weighing Balance Enclosures White Paper
Oct 27, 2009

Active Pharmaceutical Ingredients (APIs) are increasing in potency and can have potentially harmful consequences. To protect operators, a number of engineering controls are available. One such engineering control is the Esco PowderMax™ cabinet. The Esco PowderMax™ cabinet is designed to provide operator protection by using airflow to capture and draw away any harmful airborne powders away from the operator's respiratory zone. However, this inward airflow can influence the performance of highly sensitive analytical balances if the equipment is not correctly designed to mitigate airflow factors.

In order to verify the suitability of the PowderMax™ cabinet for precision micro-balance work, Esco designed and executed a study. The published results demonstrate that the PowderMax™ cabinet, at nominal airflows, can provide a stable work condition for sensitive powder weighing work, with extremely low standard deviations in the range of 0.000001 to 0.000011 for weighing 20g, 5g, and even 0.5g objects.
