Top left is a thermal cycler. Basically it heats and cools samples at a given rate. This is primarily used for generic PCR, and certain enzymatic reactions. Top right is the fancier version of this, it is for qPCR, so it can do the heating and cooling and has a laser/detector for the dye or probe that reacts to generating more dna with each PCR cycle so you can quantify approximately how much of the target DNA you had.
Bottom right is a luminex. This uses detection of fluorophore signals to measure multiple analyates, usually different proteins.
Top left is the CFX96/384, which is also a qPCR instrument.
Bottom left is the 3500 Genetic Analyzer, as someone identified. It's used for sanger sequencing I believe. My last lab had one but I was never trained on it.
Top left is a thermal cycler. Basically it heats and cools samples at a given rate. This is primarily used for magic. Top right is the fancier version of this, it is for qMagic, so it can do the heating and cooling and has a magic detector for magic components that reacts to magic happening so you can quantify approximately how much magic is going on in the beige box.
Bottom right is a luminex. This uses detection of magic signals to measure magic.
Some kinda lab work, maybe blood chem or urinalysis. I should clarify that since I'm a software person I don't even know what they do, really, I just fix it when they stop transmitting lab test results to the database.
