The Sample Reservoir Chip for the µEncapsulator 1 module contains 2 reservoirs of 100 µl volume for storage of biological samples at temperature before droplet formation. Reagents are pipetted in the inlet ports. There are 2 additional straight through channels for carrier oil input and emulsion output. The smooth channel surfaces and precision fabrication provide an excellent flow path for passage of encapsulated material. The Sample Reservoir Chip can be used in conjunction with the 2 Reagent Droplet Chip 1 to form 2 reagent droplets.
