Thermal vacuum chambers are ideal for testing components in a simulated ... It can be cooled to a temperature of roughly -190 C (-310 F), achieve a pressure of 2x10^-6 torr and complete an experiment ...

As the vacuum sucks the air out of the chamber, the air that is trapped inside the slime has less external pressure exerted on it meaning the air inside is free to expand. This is why the slime is ...

Even in highly controlled laboratory conditions, where we use vacuum pumps to reduce the pressure inside sealed chambers to one-billionth of atmospheric pressure, a sugar cube-sized volume still ...

This allowed us to keep sealing bags quickly, but also gave the chamber vacuum enough time to build pressure and really provide an amazing, airtight vacuum and seal. This model, unlike other chamber ...

or sample preparation chambers. The Evactron ES Plasma Cleaner provides rapid, effective and mild cleaning across a broad range of pressures, allowing artifact-free, high quality images, as well as ...

Through control of chamber pressure, temperature, and with the help of inductive melt stirring, it is possible to obtain homogenous alloys with desired chemistry. Melting under vacuum conditions ...
