dear brian, dear mara,
  an alternative is to reuse the bd filters. after use store them 
submersed in water, wash them with soap and a small brush and air dry 
the filters. for sterile use they can be autoclaved. this works with 
all mesh sizes multiple times.
of note: the cell suspension does not run through the washed filter 
immediately: therefore put a drop of pbs/ water on the filter from the 
opposite site first.
happy single cell preparation.
best saeed
