Low Drift

Our original type of microelectrode holder, the DB, now superceded by our ISO type. We manufacture DB holders for users who require continuity in their experiments. They are 5mm shorter than the ISO range.

The DB range has 3 types of fitting: 
S - Screw fitting for Axon HLU type headstages (including 
CV-203BU, CV-7A/B, HS-9A), 
P - Push
 fit for Axon HL-1 type headstages (including 
CV201A / 201AU) 
H - BNC connector type for HEKA Co. headstages and some NPI and Dagan amlifiers.

The holders are available for only 2 diameters of electrode glass:
1.2mm OD
1.5mm OD

Because the holders are engineered for discrete sizes of pipette glass we can ensure lower drift than those from other manufacturers whose holders can accommodate multiple sizes.

See Choosing a holder for advice on which type of holder to purchase.
