SMA Atriums Details


SMA Atriums® are stainless steel collection devices that connect to the SMA OneTouch® ICS, SMA® DDC, or SMA MicroPortable® Air Sampler.  When partnered with one of these viable monitoring instruments the SMA Atriums direct air from the environment to impact onto a media plate.  The media plate is then evaluated to determine the amount of viable contamination in the environment.

SMA Atriums are the preferred test method of pharmaceutical, biotechnology, semiconductor, and electronics organizations around the world for determining the level of viable contamination in their facilities.  Their non-turbulent design causes no disruption in unidirectional air flow, which allows placement in the most critical areas (e.g. RABS).

SMA Atriums are available in many different configurations, including a wall mountable configuration with a specifically designed bracket and Atrium base.  The SMA Atrium Easy Grip top has a concave edge designed to make the Atrium easy to handle.

SMA® Remote Atriums are designed to sample in places where the use of the standard SMA Atrium is either impractical due to size and space limitations, or the actual procedure of replacing the media plate would interfere with the manufacturing process.  The SMA Remote Atrium extension tube attaches to 1/4 inch Hytrel® tubing.

SMA Remote Atriums can be used with VAI’s Isokinetic Probe which provides a secure attachment point near the point of sample and improves air flow efficiency.  The Isokinetic Probe and tubing can be located near critical filling processes where space is limited.

When selecting an SMA Atrium it is critical to determine the desired sample time and plate exposure period.  Extended periods of active sampling can cause desiccation and dehydration of the media plate, resulting in poor or no growth of microorganisms that may have been present in the air sample.  The SMA Atrium allows for continuous, active sampling for up to 3 hours (or more), depending on the media plate fill level and selected Atrium top.  Contact VAI for more information.

SMA Atrium Parts include 1/2 and 1/4 inch SMA Atrium Tops, SMA Remote Atrium Tops, SMA Atrium Bottoms, SMA Atrium Covers, SMA Atrium Vacuum Connections, and SMA Atrium Wall Brackets.  The SMA Atrium Wall Bracket is a wall mounted shelf that holds an Atrium and an Atrium lid.  It has a quick release fitting for easy sterilization.  It is used with the Atrium bottom (SMA-316-BOTTOM-WATR) that is made to attach to the Atrium wall bracket.
