Description:
The device consists of a dual-level metallic base with a leveling foot, painted with a matte-grey finish. On the lower level (the leveling foot), there are three sequentially-stacked grayish metal disks with holes in them (swivel vanes and a turntable spindle with thrust bearing), two tall vertical metal rods at the side, and a shorter horizontal one projecting from the lower end of the nearest rod (the swivel support rods/arms and funnel bracket) hovering right above the turntable. A complex, very fragile glass siphon with a funnel would be attached here, to fill the test tubes below. All that is now missing.
On the upper end, there is a control panel covered in a plastic dust cover with many switches. The control circuit has indexing motor assembly electrodes, a motor-drive wheel, a "self-operation plug," and built-in volumetric siphoning control.
The front side of the instrument contains several electrical connections, power and data plugs.
