BoroFloat™ Glass Lapping Plate

PELCO^® Precision Angle Lapper (PAL™)

Precision Metallographic Angle Lapping and Thinning Sample Preparation for: Light Microscopy, Scanning Electron Microscopy, Atomic Force Microscopy Mechanical magnification of finite structural features Wedge sample preparation for TEM Mechanical slice sample preparation for focused ion beam thinning The PELCO PAL™ offers a unique combination of features including an intermediate sample mounting block, which facilitates the use of a regular upright optical microscope (instead of an inverted microscope) for monitoring the lapping process, and an ergonomically designed baseplate. It also allows for an easy visual inspection of the specimen frontal and side views under a stereo microscope, an integrated leveling device for establishing a reference horizontal plane rapidly and accurately, optimized dimensions and overall tool weight to produce the ideal lapping conditions for a wide variety of applications.

BoroFloat™ 8" Lapping Plate The BoroFloat™ 8" Lapping Plate is produced by a float technique that yields superior surface accuracy, typically 4 - 6 waves per inch (one wave equals 0.00002"). The resulting flatness makes this product an excellent choice for a hand lapping plate. In addition, this material exhibits excellent thermal properties and chemical resistance. This lapping plate is about three times more resistant to thermal shock than standard soda lime glass. It has the thermal expansion properties of Tempax® or Pyrex®. Chemical resistance includes water, saline solutions, neutral and acidic solutions, chlorine, bromine, iodine, and organic substances.

Surface Accuracy	4 - 6 wavelengths/inch
Diameter Tolerance	±0.5mm
Thickness Tolerance	±0.2mm
Linear Thermal Coefficient of Expansion (20° to 300°C)	3.25 x 10-6/K
