holders are designed to accept a 1 in
3 in nominal piece of glass.
The detailed specifications of the glass are as follows:
•
1 inch wide (25.4 mm, –0.45 mm, or +0.7 mm)
•
3 inches long (76.2 mm, +0.25 mm, or –1.4 mm)
•
1 mm thick (+/-0.1 mm)
•
No mirrored slides
•
High quality with low intrinsic fluorescence
•
Index of refraction from 1.510 to 1.515
Barcode and barcode label specifications
Barcode specifications for Agilent slides
The G4900DA scanner reads barcodes placed on the active side of the slide.
For backwards compatibility with the G2565AA model scanners, Agilent microarrays continue to
have barcodes on both sides. The label with the text “Agilent” denotes the active side; the label
with the numeric value is the inactive side.
