I had Flow Sciences make a training video several years ago for the proper use of their Ventilated Balance Enclosures (VBSE’s), which are low-flow hoods with excellent contaminant control.  But as with any low-flow hood – operator performance is critical and can overcome the lower flow rates.  The lower flow rates are also more susceptible to air currents, e.g., doors, intake vents to cause interference and possible employee exposures.  I believe they include they training materials with their hoods, but if not be sure to ask.

I had the reps from Flow Sciences ( in last week for a Lunch 'n Learn on their nano enclosures. Very impressive & not too costly. They had a nice bench top enclosure for weighing.

Dear  members,


   Does anyone have a source on  a containment system  for  safely weighing  dry nanomaterial?   A chemical hood is usually too turbulent for the accuracy of a Mettler balance.  Any thought you have including precaution(s) to take for this type of  work would be appreciated.  


Thank you and keep up the great work you do.
