Sample holders

Petri dish holder

The Petri dish holder accommodates plastic and glass bottom dishes up to 50 mm in diameter and 10 mm in height. It is compatible with CoreAFM and FlexAFM for stand-alone applications but also in combination with the DIMO (digital inverted microscope option).

The holder is equipped with heating elements that together with the optional TEC controller CH1 allow controlling the temperature of the sample in a range from ambient to 60°C.

The holder is compatible with Nanosurf’s environmental control option.

Environmental control option

The environmental control option consists of two parts – the environmental ring that is compatible with Nanosurf’s sample holders and the sealing membrane, which seals the gap between the scan head and the environmental ring.

Environmental control option

EC-AFM sample holder

The EC-AFM sample holder allows performing in situ electrochemical experiments. The EC-AFM sample holder accepts flat working electrodes with a thickness between 0.2 mm and 2 mm and standard 2 mm diameter reference electrodes. As electrochemical reactions may be sensitive to e.g. oxygen, the EC-AFM sample holder features an integrated environmental control ring which allows perfusion of gas and liquids.

The EC-AFM sample holder can be optionally equipped with the heating or heating/cooling elements that are controlled by the TEC controller CH1. Thus, EC experiments can be performed at different temperatures.
