Cactus Cooler is an orange–pineapple flavored soft drink sold primarily in Southern California and the surrounding Southwestern United States. Distinguished by its orange, yellow, and green label with saguaro cacti , the soda is part of Keurig Dr Pepper and was previously distributed under the Canada Dry brand.
A vacuum chamber is a rigid enclosure from which air and other gases are removed by a vacuum pump. This results in a low- pressure environment within the chamber, commonly referred to as a vacuum . A vacuum environment allows researchers to conduct physical experiments or to test mechanical devices which must operate in outer space (for example ...
Vacuum cooling is a rapid cooling technique for any porous product that has free water and uses the principle of evaporative cooling.Vacuum cooling is generally used for cooling food products that have a high water content and large porosities, due to its efficacy in losing water from both within and outside the products.
A better choice for vacuum systems is the tin-silver eutectic, Sn95Ag5 (Sn-Ag eutectic is actually 96.5-3.5); its melting point of 230 °C (446 °F) allows bakeout up to 200 °C (392 °F). A similar 95-5 alloy, Sn95Sb5, is unsuitable as antimony has similar vapor pressure as lead. Take care to remove flux residues.
In vacuum applications, a cold trap is a device that condenses all vapors except the permanent gases (hydrogen, oxygen, and nitrogen) into a liquid or solid. [ 2 ] [ needs update ] The most common objective is to prevent vapors being evacuated from an experiment from entering a vacuum pump where they would condense and contaminate it.
Non evaporable getters (NEG), based on the principle of metallic surface sorption of gas molecules, are mostly porous alloys or powder mixtures of Al, Zr, Ti, V and Fe.They help to establish and maintain vacuums by soaking up or bonding to gas molecules that remain within a partial vacuum.
