Hi,

I was wondering if there are any tricks to making needles.
We have problems with our needles,
First they are thin, it's easy to get into the worm,
but they clogg very rapidly and flow is very minimal.
As we try to break them further, they get too big
and the worms die.  So we have a hard time getting
any worms injected.

I guess there are two parameters:
type of capillary (glass thickness),
and form of the pulled needle.
What capillaries are people using?

Thanks
Thomas
