The EUROBlotMaster and the EUROBlotMaster 44 are compact tabletop devices for processing EUROIMMUN blot strips (EUROLINE, EUROLINE-WB, Westernblot). Following the software-guided loading of reagents, blot strips and samples, the devices perform all incubation and wash steps of the work protocol, as well as the dispensing of buffers, conjugates and substrate and stop solutions. Different conjugates and tests for autoimmune, infection and allergy diagnostics can be combined in one run. EUROBlotMaster devices have an integrated display with a membrane keyboard and do not require an additional PC. They are convenient and simple to operate using six keys and require minimal daily maintenance of five minutes at most.
