Chapter 4: Software Configuration
The SkanWasher 400 allows up to eight different user-defined and pro-
grammed wash sequences to be stored in memory with a battery backup. Each
wash program has the following options:
Air pressure from the internal pressure pump can be varied to control
inlet liquid flow.
Volume adjustment, conversion factor, and
σ
V can be used to fine-
tune the dispense volume to adjust for the different viscosities of
various liquids.
The position (height) of the aspirate probe above the bottom of the
well during aspiration can be varied. The amount of fluid kept in the
well can be adjusted.
Dispense probe height position in the well during washing can be set.
Up to 16 wash sequence steps can be selected. Each step can be one
of the following:
Aspirate, time in seconds [2–10 sec.]
Wash, time in seconds [0.1–10 sec.]
Dispense, volume in µ l [100–900 µl]
Soak/pause, time in minutes and seconds [1 sec.–3 min.]
The washer is pre-programmed with four typical wash sequences. These may
be removed or changed as necessary.
At the end of Appendix E, a blank program guide sheet is included to facili-
tate programming. Duplicate this sheet for your own use to save a hard copy
of each program for reference purposes.
