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.

Four different sizes of cone washers allow the holder to accommodate pipettes with outer diameters from 1.0 to 1.7 mm. Suction port connects to 1 mm ID tubing. Low-noise easy-maintenance construction. Contains a 0.25 mm silver wire. Spare components supplied are as follows: cone washers (five of each size), four 50 mm lengths of silver wire and 70 mm of silicone tubing to make new seals. BNC adapter accepts a BNC-type electrode holder.

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.
