DropPlateฎ 16/96
0.5 2.5 μl sample quantities minimizing consumption
of your samples.
16 to 96 sample disposable technology your route
to higher throughput and automation
Minimized sample evaporation, allowing time and
temperature depending assays
Dynamic range: 2 3.500 ng/μl dsDNA
No sample dilution needed
Step 1
Fluid is dispensed into input well. Dispensing is done manually or via a liquid
handling robot. The chip is not in the DropSense system during dispensing.
Step 2
Fluid is drawn into capillary channel due to capillary action (hydrophilized COC
material). The chip is now ready to be loaded into the system.
A first optical measurement will be performed to verify the absorption of the chip
material. No sample is yet in the optical pathway.
Step 3
First chamber is filled by applying a small vacuum pressure at the evacuation hole
above the spill chamber. This pressure is supplied by an external source, integrated
in the DropSense system. Another optical measurement is performed
Step 4
Second chamber is also filled (first chamber remains also filled) by applying a
higher vacuum pressure. Another optical measurement is performed
