Devices, apparatus and methods are disclosed for carrying out processing
steps involved in chemical reactions such as hybridization reactions
conducted on the surface of a substrate comprising chemical compounds
such as biopolymer features. A device comprises a housing comprising a
housing chamber. The housing comprises an opening through which a
substrate may be inserted into the housing chamber. The device may also
comprise a lift mechanism for moving the substrate in and out of the
housing chamber in a controlled manner. At least one inlet may be in
fluid communication with the housing chamber and at least one outlet may
be in fluid communication with the housing chamber. Also disclosed are
methods wherein the surface is brought into contact with a processing
fluid; and, then, the surface is removed from contact with the fluid in a
controlled manner at a rate that substantially eliminates droplet
formation of the fluid on the surface of the substrate.
