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.

The Static Line II ionizer is an antistatic device which emits negative and positive ions, neutralising the electrostatic charging.

It consists of a high voltage power pack, an ionizer electrode which is connected to the power pack by a cable, and a testing device, the MULTI CHECK.

A dial on the power pack allows for adjustment of the voltage. The correct ion emission can be achieved by turning the variable voltage dial.
