Optics
The LabChip GX Touch/GXII Touch optics provide fluorescence
detection (red excitation and red emission) for DNA, RNA, Protein
and Glycan chips and assays.
Red Laser
The LabChip GX Touch/GXII Touch instrument includes a high
intensity, long-life red diode laser to excite fluorescence on
microfluidic chips. It is expected to have a lifetime of tens of
thousands of operating hours.
Focusing and Alignment
The LabChip GX Touch/GXII Touch instruments use back-reflected
red diode laser light for automatic chip focusing.
Photodiode Detectors
The LabChip GX Touch/GXII Touch use two silicon photodiode
detectors for fluorescence detection and autofocus. Fluorescence
data can be acquired and stored at rates from 20 to 120 Hz.
Optical Train
The fluorescence excitation, fluorescence detection, and autofocus
optical trains contain several lenses and high efficiency interference
filters. The optical trains are factory aligned and do not require
adjustment.
Chip Pressure System
The pressure pump applies pressure or vacuum to the wells on the
chip to move liquid through the chip. The Pressure Pump is located
inside the LabChip GX Touch/GXII Touch instrument. O-Rings on
the
seal the chip wells and maintain the pressure.
Barcode Reader
The LabChip GX Touch/GXII Touch instrument may be equipped
with an internal Barcode Reader. The Barcode Reader reads the
customer-applied barcode on the short (portrait) edge of the
microplate.
Proper selection and placement of barcode labels is critical for
successful reading. See
Placing the Barcode on the Plate on
for specifications.
The barcode reader is internal to the system and cannot be viewed
from the outside.
