Cuts are made on the other side of the glass slide, which holds the specimen holder in place and also acts to create a smooth cutting surface for better quality cut (using standard razor blade). The glass slide has a semi-ovular cut from the bottom using a steel wheel glass cutter (see video). This cut allows the specimen to advance beyond the glass so that the specimen can be cut. Cross sectional cuts of stem are picked up with needle nose forceps and placed on a slide. Extra water was absorbed with Kim wipes separating slides.
