With these devices you can put images from two video cameras on the single video monitor. This may be extremely useful when you need to find correlation between two different processes. For example, if one camera images cells and another one is focused on pH meter display, you will be able to detect pH dependent changes in cell morphology with 1/30 second precision. VSS-1 unit split screen either vertically or horizontally and allow to change area allocated to each camera and adjust camera gain. VSS-2 unit inserts variable size rectangle of camera 2 image into camera 1 field. Both units work with any black and white analog cameras but one camera must have video synchronization input (usually standard BNC connector labeled "Gen. Lock" or "Sync.")

Picoamp-300B
This amplifier is a modification
of PA-300 model.
In designet to work with new HS-2C
headstage (shown on top of the unit) for cell electrophysiology applications.
This headstage has AxonTM
type threaded connector for stable and easy microelectrode mounting, 1
mm diameter gold plated connector for ground electrode and 2-56 screw for
system ground. Headstage connects to the amplifier with our standard
RJ-45 connector and backward compatible with PA-300 and even with BBA-02
units. However, "B" model amplifier has added Zap circuit which generate
short pulses of membrane breaking voltage and that is quite useful for
converting cell "patch" to "whole cell" configuration. Additionally, offset
and RC compensation ranges are increased to be compartible with glass microelectrodes.
This makes PA-300B
truly universal for both basic cell electrophysiology applications and
for BLM research. Once you decided to get to the basics of cellular
phenomena using artificial lipid bilayers, you only need to replace HS-2C
headstage with HS-2
or HS-2A, no
recalibration required.
