This letter serves to inform that we recommend a one directional workflow that is the
sample prep area is always located upstream of that of the BAX area as contamination
can happen when the workflow of the sample prep and BAX workflow overlaps.
While it is not necessary to have separate rooms for sample preparation and the BAX
area, we are fine if user chooses to have separate areas for sample prep and BAX
room or to use a laminar hood. Having a laminar hood is ideal but not compulsory.
