Holders are machined from polycarbonate to minimize electrical noise and are custom
bored to accommodate various diameter pipet electrode glasses. The micropipet is secured
with a rubber gasket and a polycarbonate screw
–
cap matching the OD of the pipet glass. A
1 mm pin makes electrical contact with the silver wire and plugs the holder onto the
headstage. A 1/16” OD access port is provided for applying suction to seal the pipet tip to
the cell membrane.
NOTE:
The standard holder used with the
PC
–505B
is type
QSW-AxxP
(straight body) where
"xx" specifies the glass OD in mm.
Model Cell
A model cell is included with the instrument. This model cell has three connectors, one
to simulate the bath (10M
to ground), one each to simulate a membrane patch, and one to
simulate a whole cell application. An additional model cell is included with the
HB-205
bilayer headstage to simulate a planar lipid bilayer membrane.
The model cell is used in the following familiarization instructions and is a valuable tool
in troubleshooting problems with actual setups.
