Abstract

A device for processing samples is disclosed. Interior surfaces of the device, which come in contact with fluids, define wetted surfaces. A portion of the wetted surfaces are coated with an alkylsilyl coating having the Formula I: R1, R2, R3, R4, R5, and R6 are each independently selected from (C1-C6)alkoxy, —NH(C1-C6)alkyl, —N((C1-C6)alkyl)2, OH, ORA, and halo. RA represents a point of attachment to the interior surfaces of the fluidic system. At least one of R1, R2, R3, R4, R5, and R6 is ORA. X is (C1-C20)alkyl, —O[(CH2)2O]1-20—, —(C1-C10)[NH(CO)NH(C1-C10)]1-20—, or —(C1-C10)[alkylphenyl(C1-C10)alkyl]1-20—.
