Description

The environmental cell is used for scanning samples in a controlled environment such as a liquid or inert gas. The cell is designed so that the AFM probe and the sample are held in a sealed chamber. Gases or liquids are introduced into the chamber through inlet and outlet ports. In use, the environmental cell replaces the probe holder in the TT-AFM light lever.

The environmental cell for the TT-AFM requires the user to have advanced understanding of AFM operation. Operators attempting to use the environmental cell without considerable practical AFM operational knowledge will have limited success. We recommend at least one full week of time for making the first images with the environmental cell.

Standard AFM probes are directly held in the environmental cell probe holder. A special tool is provide for extracting the probe holder from the environmental cell. Changing probes requeres precision tweezers that are included with the cell.

At the tip of the cell is a glass window that the laser light passes though before and after the light reflects of the cantilever. The body of the cell is made from aluminum with an anodized finish. A seal between the cell top and cell bottom is made with a viton o-ring. At the bottom of the cell a rubber disk is used to seal the sample holder in place. Silicon sealant is used to hold the window as well as the rubber disk in place.

Included with the environmental cell:
Cell top	Cell bottom
Probe holder	Scanner adapter
Plastic Tubing	Syringe
Probe extraction too	Precision Tweezers

The procedure for using the cell is:
	a) Screw scanner adapter on top of scanner
	b) Prepare specimen
	c) Clip specimen on sample holder
	d) Put probe in probe holder
	e) Insert probe older in top of cell
	f) Close cell, screw top and bottom together
	g) Insert cell into Light lever
	h) Pump liquid or gas into cell
	i) Lower light lever until scanner adapter engages bottom ring
	j) Aligh laser, photodetector
	k) do tip approach
	l) scan sample
