Dear Group,

We concur. We also find the most reliable method, though slow, is to use a
2 microliter pipetter and gel tips.  We invested $500 on an 8 syringe unit
but the first time we used it one of the needles stuck between the glass
plates and pulled out of the syringe.  In our hands the needles, even
though supposedly for .2 mm gels are too fat to go into the well.  Plus the
unit is stiff, must be flushed between samples and has a dead volume equal
to the sample volume.

I recently saw an ad somewhere for a multiple dispotip gel loading
pipetter.  Has anyone had a good experience with this or any other device?
