A method of switching a first fluid supplied to a dispenser with a second fluid. The method includes stopping the first fluid from flowing into a common portion of a flow system, causing a flush fluid to flow through the common portion, stopping the flush fluid from flowing into the common portion, removing the flush fluid from the common portion, causing the second fluid to flow through the common portion, and continuously circulating the first fluid to and from a reservoir without the first liquid entering the common portion of the flow system. The continuously circulating of the first fluid begins a) after stopping the fluid liquid from flowing into the common portion of the flow system and b) prior to or during the second fluid flowing through the common portion of the flow system.

Method and system for switching a dispensed fluid in a nanofabrication dispensing system

A pulsation dampener for a dispensing system comprising a housing, a diaphragm comprising at least one fluoropolymer layer, the diaphragm dividing the housing into a first compartment and a second compartment, an inlet port and an outlet port each in fluid communication with the first compartment thereby providing a flow path for a liquid to enter the first compartment via the first inlet port and exit the first compartment via the outlet port, and at least one gas disposed within the second compartment, the at least one gas having a kinetic diameter of 0.36 nm or greater, wherein the fluoropolymer of the at least one fluoropolymer layer and the at least one gas are selected such that a gas transmittance rate of the at least one gas through the diaphragm is from 0 mbar*L/second to 1*10mbar*L/second.

Pulsation dampener with gas retention

A cap, a method of using a cap, and a system for using the cap. The cap is capable of being fitted to a bottle. The cap includes a transfer port; and a vent port. The vent port includes a membrane and a valve.
