Electrode Holder for 1mm electrodes, 4mmø bar

H-7:  $64.86 - In Stock
Narishige's H-7 electrode holder holds electrodes with outer diameter between 1.0 mm and 1.5 mm. It is ideal for electrophysiology manipulations.

NOTE: If you were considering using H-7 in a microinjection setting, for example, with a microinjection manipulator such as MN-151, we recommend that you switch either to Narishige's HI-7 or Tritech Research's MINJ-4. These provide a more reliable interface for applying pressure to microinjection pipettes and obviate accidental breaking of needles.
*For O.D.1.0 - 1.5mm pipettes
*Bar O.D.4mm

The H-7 has a two pipette holding groves, so it can function as a dual pipette holder or dual electrode holder. It can hold 2 pipettes in parallel, 4mm apart from each other; however, it does not allow for fine independent positioning of the two glass needles or 2 electrodes... For positioning two pipettes or electrodes, we recommend HD-21.

Here is a mechanical drawing showing the dimensions of the end of the H-7 holder:
