In the last three decades Ozone has become a very important and efficient tool to achieve high quality pharmaceutical grade water. This paper will address two main topics that are critical for the effective use of ozone within the water processes of the life science industry.
The new Sartorius Quintix® sets new benchmarks in every aspect for standard lab balances: features, technology, ergonomic style, and, above all, the entirely new, user-friendly operating design of the Quintix® that helps make workflows much more efficient. What it boils down to is the Quintix® is fail-safe: it rules out weighing errors due to incorrect operation and eliminates the time-consuming chore of “finagling” with the settings. Fractions of a second are all it takes for any user to adapt the Quintix® to specific requirements and obtain traceable results much faster than ever.
The Test Objective is to study the containment capabilities of the BSC when using a chemo plus prep mat on the worksurface. A NuAire model NU-425-500 Class II, Type A2 BSC was set to its nominal average velocity airflow of 70 fpm downflow and 105 fpm inflow, and Personnel protection tests followed NSF/ANSI 49:2002 at nominal airflows using a chemo prep plus mat (10-3/8" x 16-1/2" size) on the worksurface in different configurations.
