1. Empty the waste bottle now, and then as needed throughout this procedure.
2. Fill each of the supply bottles connected to
Buffer valves A
,
B
,
C
, and
D
with
three liters (3000 mL) of deionized water. Place the bottles on a surface level
with the 405 LS, i.e., the adjacent (lab bench) area.
3. Run the Maintenance protocol
PRIME_ALL_BFRS
two or three times to prime
the fluid lines, manifold, and the valves.
Repeat the following steps for each valve:
1. Edit the applicable dispense protocol, for example,
QC_96_DISP_TEST
, to use
the buffer valve currently being tested.
2. Place a new 96- or 384-well microplate on the balance and zero the balance.
3. Place the microplate on the carrier and run the dispense protocol.
4. When the program is finished, carefully remove the plate and weigh it. This is
the
Total Dispense Weight
in grams.
The Total Dispense Weight should be:
l
28.8 grams ± 10%
(between 25.92 g and 31.68 g) for the 96-Tube test.
l
30.72 grams ± 10%
(between 27.65 g and 33.79 g) for 192-Tube test.
l
If the weight falls above this range, the valve may be defective. Contact BioTek.
l
If the weight falls below this range, the valve may be contaminated with fungi or
proteins and must be cleaned using an appropriate enzyme, alcohol, or a diluted
bleach solution, depending on the contaminant.
See Removing Protein Residuals
and Fungi Growth on page 124
in the Maintenance section for suggestions. After
cleaning the valve and tubing, retry the test. If the test continues to fail, contact
BioTek.
5. Record the results in the applicable worksheet.
Dispense Precision Test (192)

This test is designed for the
192-Tube
manifold. Find the Dispense Precision
(96) on page 157.

Save the plate!
When this test is complete, use the filled plate to perform the
Evacuation Efficiency Test.
1. Fill a supply bottle with 2 liters of deionized or distilled water; Buffer Switching
units use buffer valve A. Run
W-DAY_RINSE
two or three times to flush the
