Killerweed, or any one else, if you want to see an image of these machines you can go to siemens dot com/diagnostics then click on Products, then chemistry/immunoassay, then look at the menu of machines. It's kind of like the evil machines from Terminator 3: Rise of the machines. I have tried to link it before but the links do weird things. You can also do it from dadebehring dotcom/edbna2/ebusiness/company/overview.jsp then products then drug testing diagnostics then look at the menu of machines on the right. Note the placement of the dot coms.

There are other companies that make them and other immunoassay testing methods other than EMIT.
