The HS 400 Hybridization Station is used for fully automated hybridisation of up to four microarrays on slides. Incubations may be performed in the range 15–85oC. True parallel processing guarantees exact and reproducible incubation times. It offers efficient liquid agitation and on-board slide drying. Highly uniform liquid distribution ensures reproducibility for all washing steps. The HS 400 can be operated via the integrated touchscreen module or from an external PC.
