Test Tube Brushes

[labman]

Hi All,
This week I am trying to track down a supplier for test tube brushes. I need a few sizes, but most importantly, the small ones for the micro test tubes(10x75mm). The ones I have are approx. 19cm long,with 55mmx5mm white bristle brush. I would like to get the same sort, as they seem to last well. My normal supplier has only a 55mmx9mm size, and, while these fit, they are very tight, and cause a lot of breakages. They are also $4.00 each, I'm hoping to find them a bit cheaper if possible, as I have to buy class sets. Any info appreciated.
Cheers,
Lisa

Try big fat furry pipecleaners! They work wonders for semi micros, glass tubing etc
