Yes. In a vacuum there are almost no gas molecules to transfer heat through conduction or convection, making it an excellent thermal insulator. Heat transfer by gas molecules becomes negligible when the mean free path becomes extremely long, leaving radiation as the only remaining heat-transfer mechanism.

A scroll pump is an oil-free vacuum pump that compresses gas using two interleaved spiral scrolls. It’s clean, quiet, and ideal for labs and analytical instruments. Use gas ballast when pumping moisture, solvents, or condensable vapors to prevent internal condensation and extend pump life. Read more about dry vacuum pumps.

Most rotary vane pumps use mineral oil, synthetic hydrocarbon oil, or PFPE oil, depending on the application and chemical compatibility. Mineral and synthetic oils are flammable, while PFPE oils (e.g., Fomblin) are non-flammable and chemically inert. Mineral oil is the most common and cost-effective option, synthetic oil offers higher thermal stability, and PFPE oil is mainly used for pumping aggressive chemicals and oxygen, and for plasma processes.

A safety device that ruptures at a defined pressure to protect vacuum chambers and pressure vessels from over-pressurization. Read more about vacuum safety components.

A power source that delivers radio-frequency energy (typically 13.56 MHz, 27.12 MHz, or 40.68 MHz) for plasma generation, sputtering, and semiconductor processes. Read more about RF power supplies.
