Perfect Loop

The PERFECT LOOP allows you to pick up sections consistently, without causing them any damage. It is the only loop currently available where the external diameter is the same as the grid and the internal diameter slightly larger than the observed area in the electron microscope.

The thickness is about 40 microns. Due to the fact that the LOOP and the grid are of the same diameter they are attracted to one another when in water and are drawn together by the surface tension of the water. Even if the section touches the inside of the grid during blotting the area of contact is minor and, therefore, the section is not damaged.

When the grid is removed from the LOOP the sections always remain in place on the grid.
