very small FACS tubes - looking for reference/company (Jul/13/2011 )

Hi there,
some years back I used to work with very small tubes that you can put inside of the standard size FACS tubes of 5ml 12x75 mm. This was very useful for the acquisition of small volume samples avoiding the use of plates. I have no recollection of the company and cannot find these tubes (not on the BD FALCON website) but would really like to use them again.

Can any of you help out? Any information like tube size, company (or of course the reference) can be helpful. Many thanks!!!
