2. Place a new 96-well microplate on the balance and zero the balance.
3. Pipette or dispense specified volume of
Solution #1
into each well of the
microplate:
Plate
Type
Volume
(µL/well)
96 Well
300
6 Well
5560
12 Well
2240
24 Well
1120
48 Well
560
4. Place the plate on the carrier and run the
W-96_EVAC_TEST
protocol or the
protocol you created for your manifold. This protocol evacuates the wells,
leaving a small amount of residual fluid.
5. When the program is completed, remove the plate and weigh it immediately
because evaporation will affect the results. This is the
Total Residual Weight
in
grams.
6. Visually inspect the plate and note if any wells appear to have considerably
more liquid than others.
7. Use the
Evacuation Efficiency Test Worksheet
to perform data reduction:
o
Divide the
Total Residual Weight
by
number of wells
to find the
Mean
Residual Weight
.
o
The Mean Residual Weight should be
<=
.
Plate Type
Expected Mean
Residual Weight
96 Well
0.002 g
6 Well
0.6 g
12 Well
0.15 g
24 Well
0.05 g
48 Well
0.025 g
If the Mean Residual Weight is
greater than
expected, or if one or more wells
appear to have much more liquid than the others, the washer failed the test.
