Model 900 - 8
(Grinder)		 The lightweight Model 900 - 8" Grinding/Polishing Wheel is ideal for surface preparation of small metallographic specimens. The Model 900 is a variable speed unit with an operating range of 0 - 1725 RPM. This flexibility allows for high speed rough grinding and low speed final polishing. The Model 900 is designed for long life. It's molded plastic housing will never rust, and the 1/3 HP, fully grounded motor with electronic speed control is designed for regular laboratory use.
MODEL 910
(Metallurgical
Grinder/Polisher)		 The Model 910 is the first in a new generation of multi-purpose lapping machines designed for accurately lapping and polishing a wide range of materials. The 910 can be used as a standard metallurgical grinder/polisher utilizing abrasive papers, abrasive films, diamond discs, polishing cloths, etc. Or it can be used as a high precision free abrasive lapping machine for flat polishing of optical and semiconductor materials.
MODEL 920 - 8 in
Lapping Machine 		The Model 920 is the first in a new generation of multipurpose lapping machines designed for accurately lapping and polishing a wide range of materials. The 920 can be used as a standard metallurgical grinder/polisher utilizing abrasive papers, abrasive films, diamond discs, polishing cloths, etc, Or it can be used as a high precision free abrasive lapping machine for flat polishing of optical and semiconductor materials.

MODEL 650 The Model 650 Low Speed Diamond Wheel Saw is a compact, multipurpose, precision saw designed to cut a wide variety of materials with minimal subsurface damage. It's low speed makes it possible to cut fragile materials that would otherwise fracture and soft materials that would load the diamond wheel on a higher speed saw.
MODEL 660 The Model 660 is designed to be a multipurpose precision saw using diamond wheels up to 7" in diameter. It's low speed allows it to cut all materials traditionally cut with a high speed diamond wheel while also cutting very fragile and soft materials with minimal subsurface damage. A variety of sample holders provides a means to mount any shape sample while goniometer adaptability simplifies the cutting of orienting crystals.
MODEL 865 Constructed of a high impact polymer, the lightweight Model 865 Diamond Band Saw is designed for medium precision, efficient cutting of hard and brittle materials. However, the saw is rugged enough to cut through materials such as soft metals and polymers as well. Samples can be hand fed into the blade with the standard specimen guide. The diamond plated, steel core blades are designed for long life under normal conditions.

Critical Point Dryers Critical point drying is an established method of dehydrating biological tissue prior to examination in the scanning electron microscope. The technique was first introduced commercially for scanning electron microscopy (SEM) specimen preparation by Polaron in 1970. The original design concepts, which included a horizontal chamber, are still embodied in the design of the E3000 and E3100 systems.
Sputter Coaters and
SEM/TEM Carbon Coaters		 Sputter coating is the standard method for preparing non-conducting or poorly conducting specimens for observation in a scanning electron microscope (SEM). We offer low-cost, rotary-pumped systems for depositing non-oxidising metals - such as gold (Au) and platinum (Pt) - and also turbomolecular-pumped models, suitable for oxidising and non-oxidising metals - such as chromium (Cr).
Glow Discharge Systems The primary application of glow discharge is as a technique for the surface modification, or 'wetting', of newly-evaporated transmission electron microscopy (TEM) carbon support films.
Bench-Top
Vacuum Evaporators		 Thermal evaporation under high vacuum is an established method of depositing thin layers of metals and carbon. Typical applications include the production of support films and specimen replicas for transmission electron microscopy (TEM) and many thin-film applications.
RF Plasma Etchers/Plasma
Reactors		 RF plasma allows the low-temperature modification of a wide range of specimens and substrates. Plasma etching is generally confined to the semiconductor industry, typically for the removal of silicon layers using reactive gases, such as CF4 and for the removal of Photoresist using oxygen.
