Pipette Holders
HL-U: Connects to all U-type headstages

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 you need need to measure the input pin on the headstage (you can measure from your old electrode holder).
- If it is 1 mm diameter, then you need HL-1.
- If it is 2 mm diameter, then you need HL-2. HL-1 and HL-2 are only for smooth collets, not threaded.
For use only with threaded headstage collets.
