Chapter 4: Software Configuration
The SkanWasher 300 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,
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:
z
Aspirate, time in seconds [2–10 sec.]
z
Wash, time in seconds [0.1–10 sec.]
z
Wash, volume in µl [100–900 µl]
z
Dispense, volume in µl [100–350 µl]
z
Wash from inlet, time in seconds [0.1–10 sec.]
z
Soak/pause, time in minutes and seconds [1 sec.–2 min 50 sec.]
The washer is pre-programmed with four typical wash sequences. These may
be removed or changed as necessary.
At the end of this Guide, a blank program guide sheet is included to facilitate
programming. Duplicate this sheet for your own use to save a hard copy of
each program for reference purposes.
