7 System Fast 96- Well Sample Block (PN 4453559)

Decontaminate the sample block

Clean the sample block to eliminate fluorescent contaminants from the ViiA

™

7 System sample block. Contamination is generally evident

in failed background calibrations where one or more wells consistently exhibit abnormally high signals.

CAUTION!

PHYSICAL INJURY HAZARD

. Do not remove the ViiA

™

7 System cover. There are no instrument components that you

can safely service yourself. If you suspect a problem, contact an Applied Biosystems Service Representative.

CAUTION!

PHYSICAL INJURY HAZARD

. During instrument operation, the sample block can be heated to 100 °C. Before

performing the following procedure, be sure to wait until the sample block reaches room temperature.

CAUTION!

Before using a cleaning or decontamination method other than those recommended by the Applied Biosystems, verify

with Applied Biosystems that the proposed method will not damage the equipment.

Materials required

• Bleach, 10% solution

• Chemwipe

• Cotton or nylon swabs

• Lint-free cloths

• Ethanol, 95% solution

• Safety glasses

• Pipette (100-

L) with pipette tips

• Powder-free gloves

• Screwdriver

• Deionized water

How to handle the sample block

To prevent damaging or contaminating the sample block, handle the assembly as shown. Also, when the
assembly has been removed from the ViiA

™

7 System, place the sample block on a clean, dry surface or

in its shipping container.
