Pipette Holders

How to know which pipette holder you need:

• Is the collar (where the holder attaches to the headstage) threaded or smooth?
• If it is threaded, then you need the HL-U (most common).
• If it does NOT have threads, then Molecular Devices no longer makes electrode holders for you.

For use only with threaded headstage collets.
