Hardware architecture of analyzers

An automated method for isolating and analyzing at least one nucleic acid analyte in an analytical apparatus, comprising the steps of:

• a) providing an analytical apparatus for isolating and analyzing said at least one nucleic acid analyte, said apparatus comprising the following modules arranged along an axis, from a proximate to a distal end:
• (i) a first module for receiving and dispensing a sample to be analyzed, said first module comprising a fluid dispenser;
• (ii) a second module for isolating said nucleic acid analyte to be analyzed, wherein said second module comprises a first and a second, opposing side;
• and (iii) a third module for analyzing said nucleic acid analyte;
• wherein the first module is fixed to the first side of the second module, and the second module is fixed on the second side of the second module to the third module;
• said apparatus further comprising:
• (iv) a stacker positioned along said axis and comprising a plurality of consumables;
• and (v) a transport module for transferring consumables along said axis between each of said stacker and modules (i)-(iii);
• b) receiving a sample comprised in a sample container in said first module;
• c) transporting, via said transport module, a first consumable from said stacker to said first module;
• d) dispensing said sample into said first consumable;
• e) transporting, via said transport module, said first consumable from said first module to said second module;
• f) isolating said nucleic acid analyte in said second module;
• and
• g) analyzing said nucleic acid analyte in said third module.
