Abstract
The present invention provides for a reagent splitting/dispensing device and method that can prevent contamination of an operation fluid when a reagent dispensing nozzle is in a waiting state and prevent falling of a droplet. The reagent splitting/dispensing method includes disposing and adjusting an air layer between an interface of an operation fluid and a reagent aspirated and subsequently dispensed from a nozzle tip end in an reagent dispensing nozzle.
