The STX1000 is the largest carrousel based incubator of the StoreX series with smallest footprint in the industry. STX1000 houses two independently operating carrousels. The transport lift is located on the back side of the incubation chamber between the two carrousels having three rotation positions – left carrousel, right carrousel and transfer station position. The Gate and therefore the transfer station are located in the center of the back side of the instrument. Two large user doors on the front side of the incubator allow simple and easy manual access to the plates inside the incubation chamber. For manual access the carrousels may be positioned automatically or rotated manually.
