Surgicel is a hemostatic agent (blood-clot-inducing material) made of an oxidized cellulose polymer (the unit is polyanhydroglucuronic acid), manufactured by the Ethicon subsidiary of Johnson And Johnson. It was introduced into clinical practice in 1947. It is used to control post-surgical bleeding.
Multi Stage: (More than one level of heating or cooling) Multi Stage heating means that you have two levels of heat in your home. You will perhaps have a furnace and another method of heat like a solar panel. The second level of heat is commonly referred to as an emergency heat setting.
Single stage furnace. A single stage furnace or 1-stage furnace means has only 1 setting (high) so whenever itâs operating, itâs running at full capacity-no matter how cold it is outside. A single stage furnace is not as efficient as every time it turns on, itâs working at full blast to produce as much energy as possible. 2-stage furnace more efficient than 1 stage So, you have probably already guessed that a 2-stage furnace has 2 levels of output-high and low.
