An old, but working manual micromanipulator and mechanical stage are available to a good home. Both likely need a tune-up. They were made by Lawrence Instruments years ago in Hayward CA. Thousands of tetrads have been dissected with the instrument. A user will need a simple compound microscope whose stage remains stationary during focusing and can be swapped out for this mechanical stage. Serious inquires only.
