Abstract

See full text

A method for operating a nucleic acid sequencing instrument with movable flow cells. The method includes providing a flow cell having a flow path with an inlet port and an outlet port and filling the flow path, from the inlet port to the outlet port, with a first liquid reagent. The method also includes providing a station block having an inlet passage and an outlet passage, mounting the flow cell on the station block with the inlet port in fluid communication with the inlet passage and the outlet port in fluid communication with the outlet passage, introducing a gaseous bubble into the inlet port, conveying a second liquid reagent from the inlet passage into the inlet port to move the gaseous bubble through the flow path and into the outlet passage and fill the flow passage with the second liquid reagent, and removing the flow cell from the station block.
