Abstract
A method of continuously spotting a liquid onto a predetermined number of members to be spotted with the liquid includes the steps of mounting a disposable spotting tip on a suction nozzle, sucking the liquid in the spotting tip in a predetermined amount larger than the predetermined number times the amount for one spotting and discharging the liquid onto the members in sequence by the amount for one spotting by introducing a predetermined discharge pressure into the spotting tip. A signal related to the vapor pressure in atmosphere is obtained and the discharge pressure is corrected according to the change in the vapor pressure inside the spotting tip after the liquid is sucked in the spotting tip so that the same amount of the liquid is discharged onto all the members.
