Proper BeadChip placement prevents wicking, uneven drying, and pooled dye protectant.
30 Place the tube rack into the vacuum desiccator.
Each desiccator can hold one tube rack (eight BeadChips).
31 Make sure that the vacuum desiccator valve is seated tightly and securely, and remove the red plug from
the three-way valve.
32 Gently lift the vacuum desiccator lid to ensure proper sealing. Make sure that the lid does not lift off the
desiccator base.
33 Dry the BeadChips in the vacuum desiccator for 50–55 minutes at 675 mm Hg (0.9 bar).
Drying times can vary according to room temperature and humidity.
34 Release the vacuum by turning the handle slowly.
WARNING
Make sure that air enters the desiccator very slowly to avoid disturbing the contents. Improper use of
the vacuum desiccator can result in damage to the BeadChips, especially if you remove the valve plug
while a vacuum is applied. For detailed vacuum desiccator instructions, see the documentation
included with the desiccator.
35 Return the desiccator to storage. Store with the red valve plug in the three-way valve of the desiccator to
prevent dust and lint from accumulating in the valve port.
36 Touch the edges of the BeadChips (do not touch arrays) to make sure etched, barcoded sides are dry.
37 Clean the back of each BeadChip using a Kimwipe sprayed with 70% EtOH:
a
Hold the BeadChip at a downward angle to prevent excess EtOH from dripping onto the stripes.
b
Without touching the stripes, wipe the underside of the BeadChip until XC4 is removed (5–6 times).
38 Clean the glass back plates.
