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.

Important Notes

• We are now only selling the ‘U-type’ headstages with the threaded white PTFE inert collets, which connect only to HL-U holders, or U-type adapters and model cells.
• All adapters and holders must be ordered separately.
