I use Cat# 484775 filtration dropper tips available from Immunon/Lipshaw
800.245.6212
They fit a 8 or 15 ml plastic squeeze type bottle. I have one of these
bottles that I re-use. Very easy and very convenient.

Just curious, what are people using to filter DAB before applying to 
tissue sections?  Microfilters, non sterile variety, for syringes? 
or just a filter paper, # of filter paper please, ie Whatman # or 
an equivalent. 

this is for a very small amount of DAB, 2.5 mls frequently.
