Compounding equipment placed in a cleanroom must be constructed with materials that are highly durable, non-shedding and can withstand rigorous cleaning protocols. All laminar flow and compounding equipment manufactured by Germfree is constructed with 100% stainless steel. The physical properties of stainless steel make it inherently optimal for the demands of cleanroom equipment.

Our Horizontal Laminar Flow Hoods are USP 797 compliant and designed for the handling of sterile products in an aseptic working environment. The work area is continuously bathed with positive pressure ISO 5/Class 100 horizontal laminar flow air that has passed through a High Efficiency Particulate Air (HEPA) filter. This filter removes organisms and particulates 0.3 micron in size with an efficiency of 99.99%. The laminar airflow principle consists of moving individual streams of unidirectional, ultra-clean air along parallel lines with minimal turbulence. The HEPA filter is positioned in the rear of the work area and is protected by a removable, perforated metal diffuser.

Proper disinfection protocols are critical in sterile compounding areas. SOPs demand frequent cleaning and may utilize strong chemicals. Best practices for cleanroom operations indicate that both the interior work area, as well as the exterior surfaces of hoods are effectively cleaned. Stainless steel is preferred for its resistant properties and overall ease of cleaning.

It is also imperative that core compounding equipment is rugged, durable and non-shedding. Stainless steel will not corrode nor shed even when impacted by the ongoing wear of a high production environment. Certain painted or coated materials present a plausible risk of corrosion or shedding after repeated exposure to harsh chemicals and long-term use.
