Claim 5:
6. A method of microfluidic droplet dispensing, the method comprising:
using a microfluidic droplet dispensing system as claimed in claim 1 in a method comprising:
receiving droplets for dispensing in a droplet feed line;
providing said droplets for dispensing to a droplet outlet line coupled to a droplet outlet;
allowing a waste flow from said droplet outlet line;
controlling the ejection of droplets from said droplet output by selectively applying increased pressure to said droplet outlet line; and
protecting droplets in said droplet feed line from said selectively applied increased pressure by pressurising a region of said droplet feed line upstream of a location where said increased pressure is applied.
