Laboratory grade agents

Laboratory grade agents are typically colorless with a consistency ranging from water to motor oil. Salts are colorless to white crystalline solids. Neither solids nor liquids have any significant odor when pure. 

Laboratory grade agents are typically white, to pale yellow crystalline solids. Some are hygroscopic or deliquescent. They have little or no odor. 

Laboratory grade agents are typically colorless oily liquids or solids. They have little or no odor. Salts of nitrogen vesicants are typically white odorless solids. High concentrations of vesicants can cause eye irritation. Because of the lewisite (C04-A002) component, HL (C03-A010) vapors cause immediate irritation to the eyes, nose, throat, and skin. 

Laboratory grade agents are typically colorless crystalline solids. They have intense, penetrating, and disagreeable odors detectable at very low levels. 

Laboratory grade agents are typically colorless liquids or solids. Depending on the specific agent, liquids may be mobile, viscous, or even waxy in nature. Many solids are salts of the free-base liquid that are colorless to white to beige crystalline materials. In either state, these materials typically have little or no odor when pure. 

Laboratory grade agents are typically colorless to yellow or green liquids or solids. Pure materials are typically odorless. 

Notes. (1) Laboratory grade glycerol may be used since anhydrous glycerol is not necessary when iodine is used as the oxidising agent. Anhydrous glycerol may be pre-... 

Deacidifying Agents. Magnesium bicarbonate solution (pH 6.4) was made from laboratory grade magnesium hydroxide using dry ice as the source of carbon dioxide (10). 

Blood cultures are the essential laboratory test for the diagnosis and treatment of IE. Typically, patients with IE have a low-grade consistent bacteremia, with approximately 80% of cases having less than 100 CFU/mL in the bloodstream.1 Blood culture results are critical for determining the most appropriate therapy. Three blood culture sets should be drawn within the initial 24 hours to determine the etiologic agent.
