Biorad sell empty "biospin" columns. These can be used in conjunction with
a 1.5ml microtube for spin column applications. (They can also be used for
gravity applications). I don't know if these are suitable for you. The 
exact dimensions are 0.64 x 6cm and they hold upto 1.2ml of chromotography
media.

cat no: 732-6008 (100 empty columns)
