  Compressor Lever

  A compressor lever was designed to contain living (and moving) specimens for observation under a microscope. The thick brass plate connects to a swivel arm which provides a pivot for a bar that holds at one end a glass disk in a gimbal. The other end has a screw with a knurled knob that provides the leverage to press the glass disc down on the thick glass disc held in the plate with the specimen sandwiched between discs.
