Periodic Maintenance

S-Decontaminate

Includes prompts for first running disinfectant and later running water
through the system. It can be easily modified to suit any major
cleaning effort. The A or B suffix identifies the syringe the protocol is
designed for.

W-LONG_
SHUTDOWN

Helps implement the recommended procedure for preparing the
instrument for storage. This protocol includes prompts for running
disinfectant, then water, and lastly, air through the system.

S-LONG_
SHUTDOWN

Prepares the instrument for long-term storage. This protocol includes
prompts for running disinfectant, then water, and lastly, air through
the system. Defined to use Syringe A or B.

W-PRIME_40

Simple prime routine.

QC (Quality Control) Protocols

Manifold-Specific

QC_96_DISP_TEST

Dispense precision test protocol for 96-well wash manifold.

QC_96_EVAC_TEST

Evacuation efficiency test protocol for 96-well wash manifold.

QC_SA-1536_
DISP_TEST

Dispense precision test protocol for 32-tube Syringe A manifold.

QC_SB-1536_
DISP_TEST

Dispense precision test protocol for 32-tube Syringe B manifold.

QC_P-1536_DISP_
TEST

Dispense precision test protocol for Peri-pump 1 µL cassette and
1536-well plate. (P2 protocols are for the secondary Peri-pump)

Predefined Sample Protocols

The "Sample" protocols are provided to facilitate learning. Some samples are model
specific. "P2" protocols are copies of the primary protocol but defined for the
Secondary Peri-pump.

LHC users

: You may need to customize the protocols

(as described on page 120)

to

match your instrument's settings.

Serial dilutions

P-96_
DILUTION

Peri-pump serial dilution protocol dispenses 20 µL to 240 µL in 20 µL
increments to each column of the plate. 20 µL to column 1; 40 µL to
column 2; 60 µL to column 3; and so on till 240 µL to column 12.
