Two typical examples: Left - Krytox, a fluoroether-based grease; Right - a silicone-based high vacuum grease by Dow Corning. Apiezon, silicone-based, and fluoroether-based greases are all used commonly in laboratories for lubricating stopcocks and ground glass joints. The grease helps to prevent joints from "freezing", as well as ensuring high ...

The U.S. Department of Agriculture (USDA) recommends cooking turkey to an internal temperature of 165°F in the thickest part of the breast and thigh. This ensure that all harmful bacteria is ...
Replacement cost (time and financial) Aesthetic; Ease of removal; Marginal integrity; Planned restoration (including change from a crown to a bridge, or adapting the crown design to act as abutment for a partial denture) Access required to treat the tooth safely and effectively (especially with regards to access cavity design)
