Allied High Tech TechPress 3 Mounting Press
The TechPress 3 is used to encapsulate samples for further preparation. It has a variety of adjustable programs that contain multiple parameters to tailor to specific needs, including: mold size, single mount or duplexing, resin type, temperature, curing time, cooling time, and pressure. Up to 2 mounts can be produced at a time using the duplex spacer.

Allied High Tech MetPrep 3 Grinder/Polisher with Power Head and AD-5 Fluid Dispenser
The MetPrep 3 Grinder/Polisher with Power Head and the AD-5 Fluid Dispenser combine to provide highly customizable semi-autonomous programs that ensure that sample polishing and grinding is done in a controlled, accurate manner. The power head on the MetPrep 3 is able to apply force centrally or to each individual mold, up to 4 molds at a time. The tilt-up design allows for easy access to the sample holder and the magnetic platten, eliminating the need to reposition the head during sample preparation. The AD-5 interfaces with the MetPrep 3 to provide automatic dispensing of the polishing suspensions and lubricants. It has 5 dispensing positions, two of which have a flush cycle to help prevent any clogging when using colloidal suspensions. It also has mist-free drip delivery to the polishing surface.

Allied High Tech TechCut 4 Precision Low Speed Saw
The TechCut 4 is a precision low speed saw that is ideal for cutting small, delicate samples that do not like the increased heat that is caused by high speed cutting. A counterweight system in the sample holder helps to balance or apply a downward force during the cutting process. Cutting fluid is used by the TechCut to help cool the samples. It can cut samples up to 2 inches thick.
