Abstract

Provided is a sequenced fluid control device that includes a pneumatic driver module, a fluid cartridge having at least one fluid chamber and at least one waste chamber, and at least one sample delivery element disposed to sealably contact the fluid cartridge forming a main chamber containing a sample, where the fluid cartridge is also disposed to sealably contact the pneumatic driver module. The pneumatic driver module injects gas into or withdraws gas from the fluid cartridge, where the gas directly contacts at least one fluid causing at least one fluid to flow through channels disposed to connect at least one fluid chamber to the sample delivery element and disposed to connect the sample delivery element to the at least one waste chamber or waste channel, where a sample on the sample delivery element is exposed to the at least one fluid.

Dependent claims

A sequenced fluid control device comprising:

a. a pneumatic driver module;
b. a fluid cartridge, wherein said fluid cartridge comprises at least one fluid chamber and at least one waste chamber;
and
c. at least one sample delivery element, wherein said at least one sample delivery element is disposed to sealably contact said fluid cartridge, wherein said fluid cartridge is also sealably engaged to said pneumatic driver module, wherein said pneumatic driver module injects gas into or withdraws gas from said fluid cartridge, wherein said gas directly contacts at least one liquid or suspension causing said at least one liquid or suspension to flow through channels disposed to connect said at least one fluid chamber to said sample delivery element and disposed to connect said sample delivery element to said at least one waste chamber or channel, wherein at least one sample on said sample delivery element is exposed to said at least one liquid or suspension.
