Title:
VACUUM SYSTEMS FOR EPOXY MOUNTING OF MATERIAL SAMPLES
Document Type and Number:
WIPO Patent Application WO/2020/191552
Kind Code:
A1
Abstract:
Vacuum systems for epoxy mounting of material samples are disclosed. In some examples, a vacuum system may be a castable and/or cold mounting vacuum system that facilitates mounting and/or encapsulation of material samples in epoxy resin under low, vacuum, and/or near vacuum pressure. In some examples, the vacuum system may comprise a flow control device configured to control epoxy flow through a dispensing tube that connects to a hollow vacuum chamber. In some examples, the vacuum chamber may have an opening encircled by a rim sandwiched between upper and lower portions of a sealing ring. A movable lid may be configured to press down on the upper portion of the sealing ring when in a closed position, so as to seal the opening.
