摘要

PROBLEM TO BE SOLVED: To provide a droplet discharge head suitable for discharging a sample solution especially a sample solution containing bio-related substance.;SOLUTION: In the droplet discharge head 1 for discharging the sample solution, a section of the inner wall of the droplet discharge head 1 in contact with the sample solution is covered with a polymer formed of an unsaturated compound unit containing a phosphorylcholine group or a copolymer containing this unit. The problem is solved by the droplet discharge head. The droplet discharge head is preferably of an electrostatic drive type or of a piezoelectric drive type.;COPYRIGHT: (C)2005,JPO&NCIPI
