Esslingen (Germany), January 2021 – SimpliVac™, the new castable vacuum mounting system by Buehler – ITW Test & Measurement GmbH, allows impregnation of porous samples or structures more efficiently by means of an automatic cycle control system. The system generates a vacuum – reliably, rapidly and efficiently, and without the need for an external pump. Thus, pores and cracks will be filled completely with epoxy resin, resulting in optimized edge retention for metallographic examinations. The system is also ideal for mounting delicate samples where pre-impregnation before sectioning and/or grinding ensures samples are well protected. 

The number of cycles, the vacuum level and the time under vacuum can be set according to your needs. To optimize the mounting process, multiple cycles can be run without user intervention between cycles. Due to these special features, SimpliVac ensures consistent uniformity, even at high throughput, and reduces the time required to complete the mounting process. The large chamber diameter allows simultaneous mounting of multiple small samples. Alternatively, SimpliVac can also accommodate samples with larger dimensions. Its compact and small footprint allows more space on the lab bench.

The new vacuum impregnation system offers cold mounting solution of test samples to both quality control and/or research laboratories. Examples include electronics components, thermal spray coatings, additive manufactured components and other specialty aerospace surface treated test samples. Technicians or metallographers will appreciate the ability to optimize sample impregnation in a faster, more automated way. SimpliVac is easy to use.

When it comes to hot compression mounting, the equivalent of the new SimpliVac is the SimpliMet™ 4000 by Buehler, for quick and reliable use. It is ideal for demanding industrial environments, both in terms of sample throughput and mounting quality.
