The MultiPrep™ System enables precise semiautomatic sample preparation of a wide range of materials for microscopic (optical, SEM, TEM, AFM, etc.) evaluation. It can be used for parallel polishing or angled polishing.

The TechCut 4™ is a precision low speed saw excellent for cutting smaller, delicate samples. The pivoting cutting arm has adjustable weights to apply or counterbalance downward force to the sample during sectioning. Cutting fluid is drawn from the reservoir by the blade to cool the sample. With a 3" to 6" blade range, samples up to 2" thick can be sectioned.

The Au-Pd sputter coater is used for producing an even coating on the surface of the specimen. The coating will help inhibit charging, reduce thermal damage, and improve secondary electron emission which are beneficial for Scanning Electron Microscopy.

The Cressington 108 carbon coaters use carbon rod as the evaporation source. It is generally used for coating SEM or TEM samples where metal coatings need to be avoided. It offers the choice of either manual or automatic evaporation. In manual mode the evaporation source can be operated in "pulse" or "continuous" modes.

The FEI Vitrobot (Vitrification Robot) Mark III (Type FP 5350/61) is a fully PC-controlled cryo-plunger for vitrification (= rapid cooling) of aqueous samples used later in cryo-electron microscopy (typically in JEOL JEM-2100 TEM).

The Fischione 1020 plasma cleaner can be used for gently removed organic contamination from both TEM and SEM samples and specimen holders by using Argon-oxygen high frequency plasma. The plasma cleaner has an automated timer control and accepts TEM specimen holders and SEM holders.

It is fast and reliable mechanical method of pre-thinning TEM sample to near electron transparency to greatly reduce ion milling times and uneven thinning. Advantages includes: Large transparent areas; stronger specimen with a thick supporting rim to protect and strengthen the specimen after dimpling; accurate depth and thickness control.

The Hysitron (now Bruker) P195 In-Situ TEM Picoindenter is for quantitative, direct-observation, nanomechanical testing inside TEM.

Room-temperature and cryo-sectioning of biological and industrial specimens

The MRI-150 low-speed diamond saw equips with a digital micrometer and digital speed display controller. It is a tool for cutting/dicing/slicing materials (metals, ceramic, etc) up to an inch thickness. Cutting fluid is drawn from the reservoir by the blade to cool the sample.

The Polaron Carbon String Coater use carbon rod and carbon string as the evaporation source respectively.

Vibratory polishing is an effective final polishing technique that is widely used with metals that are difficult to polish. The vibrations in both vertical and horizontal directions produced by electromagnetic forces induce the sample to move about its axis and around the cloth periphery. The vibration amplitude is adjusted to a level just adequate to produce smooth movement around the bowl. The gentle polishing greatly reduced the surface residual stress and strain.

The Well Precision Diamond Wire Saw is used for precise cutting of small samples. It uses a stainless steel wire with diamonds embedded into the surface of the wire as the “cutting tool”. The wire is wound onto a drum which mounts onto a precision reciprocating motor. The wire diameters range from 0.06mm (0.002 in.) to 0.70mm (.028 in.).
