How to Make an Inexpensive Microtome

Hi All,

I’m making inexpensive microtomes to use with the foldscopes.

Here are the items I used.

You can use either an empty wooden or plastic thread spool. In order to have a surface on which to glue the nut and to have a firm cutting surface, glue a metal washer on each end of the plastic spool. The wooden spool didn’t seem to need one.

I used 1/4-20 x 2 inch flat Phillips bolts with nuts which fit into the spools nicely. Glue the nut to the end of the spool using a hot glue gun or other waterproof glue.

Then glue a small wooden craft stick to the end of the bolt to use to turn it.

You can mark increments on the spool with a waterproof marking pen for uniform samples. Two strips of carrot can be used to hold the specimen in the microtome.

Single-side razor blades are used to cut the section. Dip the blade and section into a bowl of water and the section should float off.




Have fun! Post pictures.
