Microelectrode holders - DB Range
Our original range of microelectrode holders, now superceded by our ISO range. We manufacture DB holders for users who require continuity in their experiments. They are 5mm shorter than the ISO range. The range comes with 3 types of fitting; S - Screw fitting for Axon HLU type headstages, P - Push fit for Axon HL-1 type headstages and H - BNC connector type for HEKA Co. headstages and some NPI and Dagan amlifiers.
Microelectrode holders - ISO Range
Over 2 years in development, and in use in many of the best electrophysiology laboratories in the world since 2009, this design offers electrophysiologists a holder with the highest mechanical stability and low noise. It offers major improvements over the original DB range that virtually eliminate pipette movement and air leakage. A longer barrel allows for the insertion of a small polycarbonate cylinder between the two O-rings which keeps everything rigid. The cylinder is precision milled at both ends to hold the O-rings in place.
Microelectrode spares
O-rings, wire seals, replacement gold-plated pins and BNC adapter for all our current ranges of holder.
Magnetic perfusion tube holders
Magnetic 'widgets' for holding perfusion lines, bath electrodes etc. on an electrophysiology rig.
